Scripts and styles only run from there. For name spacing purposes it’s good form to put your (Github) username in the path as well, so create, for instance `Library/myuser/My Library`.\n\nThen, decorate your library page with some [[Frontmatter]]. Here is an minimal example library that defines a new “Hello world” command:\n\n    ---\n    name: Library/myuser/My Library\n    tags: meta/library\n    ---\n    This implements my super awesome hello world library!\n\n    ```space-lua\n    command.define {\n      name = \"Hello world\",\n      run = function()\n        editor.flashNotification \"Hello world!\"\n      end\n    }\n    ```\n\nIf your library calls `tag.define`, `config.set` or `config.define` in a `space-lua` block, add a `-- boot: true` comment line to that block so the call applies before indexing and first render. See [[Space Lua#Definition loading]].\n\n> **note** Important\n> The `name` key _has_ to match your page’s full (path) name. Otherwise a validation error will appear on the frontmatter. When another user installs your library, they will install it to the location specified here.\n\nIf you want to distribute additional pages or files with the library (such as `.plug.js` files) make sure that they are kept at the same folder level as your library page. For instance if your library page is `Library/myuser/My Library` you can have a `Library/myuser/myplug.plug.js` and then mark it for distribution by adding it to the `files` key in your frontmatter, e.g.:\n\n```\n---\nname: Library/myuser/My Library\ntags: meta/library\nfiles:\n- myplug.plug.js\n---\n```\n\n# Require other libraries\nWhen your library builds on another library, list it under `requires` rather than copying its pages or files into yours. Installing your library then installs it too, and it can’t be removed while your library is installed:\n\n```\n---\nname: Library/myuser/Themes/Paper\ntags: meta/library\nrequires:\n- ../Fonts/Lora.md\n- github:otheruser/silverbullet-libraries@main/Library/otheruser/Inter.md\n---\n```\n\nEach entry is either a full URI (the one you would install that library from) or a path relative to your library’s own published URI, such as `../Fonts/Lora.md` (not starting with `/`). A relative path keeps the repository and branch your library was installed from, so a library installed from a release or a branch gets its requirements from the same place. Prefer relative paths for libraries in the same repository, and full URIs for anyone else’s. See [[Library#Libraries that require other libraries]] for how installing, updating and removing treat requirements.\n\n# Share the library\nAt this stage you can put your library file anywhere you like with a URL. However, for convenience, it’s good to use [[Share]] support for publishing.\n\nFor the purposes of this example, let’s use Github. Create a [[^Library/Std/Infrastructure/Github]] token and configure it as specified in the [[^Library/Std/Infrastructure/Github#Configuration|instructions]].\n\n[[^Library/Std/Infrastructure/Github]] share support offers two options: Gists and Github repo files. Let’s use a Github repo.\n\n[Create a new github repo](https://github.com/new), you can name it something like `silverbullet-libraries`.\n\nIn your own writable space, open the library page and run the `Share: Page` command, then select “Github file”. This will ask for a few things:\n1. The repo name: enter your `user/repo` here\n2. The branch name: you can keep this as `main`\n3. The file name: while this defaults to using your full page, remove that and just name it e.g. `My Library.md`\n4. A commit message\n\nIf all went well, an initial version of your page should now be uploaded to github, check your repo page.\n\nYou’ll notice that a few [[Share]] related frontmatter keys were set in your local copy. You can now make further changes to your library and run the `Share: Page` command again. After entering another commit message your page will be pushed again. This is how you publish new versions of your library for other people to use.\n\nIf you used `files` to include additional assets, you have to commit those to the repository through other means.\n\nYour library is now ready to install, you can test this by running `Library: Install` in a fresh space. As URI use the value of what is generated under `share.uri` in your library’s frontmatter.\n\nYou can now [broadcast that your library is ready to install](https://community.silverbullet.md/c/plugs-libraries/14)!\n\n# Create a repository\nIf you develop a few libraries, it may be good to make them more discoverable. To do so, you can group them in a [[Repository|Repository]].\n\nFor this, create another page in your space, this time under `Library/Repository/`, e.g. `Library/Repository/myuser` and tag it with `#meta/repository`.\n\nIn the page body, put a list of all your libraries, encoded as [[Tag/data|data objects]] as follows:\n\n    ---\n    tags: meta/repository\n    ---\n    This is my curated list of awesome libraries!\n\n    ```#meta/library/remote\n    name: Library1\n    description: This is my first awesome library\n    website: http://url.com/to/docs\n    uri: https://github.com/myuser/silverbullet-libraries/blob/main/Library1.md\n    ---\n    name: Library2\n    description: This is my second awesome library\n    uri: https://github.com/myuser/silverbullet-libraries/blob/main/Library2.md\n    ```\n\nRequired keys are:\n* `name`: a descriptive name of your library.\n  **Note**: this name is _not_ used as an installation location, the installation location is determined by the `name` key in the library itself.\n* `uri`: The URI to install the library from.\n\nAdditional recommended keys are:\n* `description`: a more elaborate description of the library and its functionality\n* `author`: who developed this library\n* `website`: a website URL for more information\n* `requires`: the library’s `requires` list, copied from its page, so the Library Manager can show what it requires before it is installed. Relative paths resolve against the entry’s `uri`. Installing always follows the library page’s own list.\n\nNow share this repo page using [[Share]] to the same github repo (or any other, it doesn’t really matter), and call it `REPO.md` (by convention).\n\nThen announce to the [community](https://community.silverbullet.md/c/plugs-libraries/14) that your repo is open for business and they can add it via the `Library: Add Repository` command (using the same `share.uri` set in your frontmatter).\n"},{"path":"Library/Page Templates/ADR.md","lastModified":1794686602000,"text":"---\ndescription: Template for an Architecture Decision Record (ADR).\ncommand: \"ADR: New\"\nsuggestedName: \"ADR/000 Untitled Decision\"\nconfirmName: true\ntags: meta/template/page\nfrontmatter: |\n  tags: adr\n  status: proposed\n  date: \"${date.today()}\"\n  deciders: \"[[Zef Hemel]]\"\n  owner: \"[[Zef Hemel]]\"\n  lastReviewed: \"${date.today()}\"\n  supersededBy:\n  dependsOn:\n  related:\n---\n# Context\nThe problem, the forces at play, and the constraints that made a decision necessary.

Empty groups return null (except `count` which returns 0 and `string_agg` which returns an empty string).\n\n# Querying available aggregates\n\nAll aggregates (built-in, user-defined, and aliases) are queryable via `index.aggregates()`:\n\n```lua\n-- List all\n${query[[from index.aggregates()]]}\n\n-- Only builtins\n${query[[from index.aggregates() where builtin]]}\n\n-- Only aliases\n${query[[from index.aggregates() where target]]}\n\n-- Only user-defined (non-builtin, non-alias)\n${query[[from index.aggregates() where not builtin and not target]]}\n```\n\nEach row includes the following columns: `builtin`, `name`, `description`, `initialize`, `iterate`, `finish`, and `target`. The `initialize`, `iterate`, and `finish` columns are represented by boolean values.\n\n# API\n\n## aggregate.define(spec)\n\nDefines a new aggregate function. Required keys:\n\n* `name`: name of the aggregate (used in queries as `name(expr)`)\n* `initialize`: function that returns the initial state\n* `iterate`: function(state, value) that returns updated state\n\nOptional keys:\n\n* `description`: description of the aggregate\n* `finish`: `function(state)` that transforms the final state into the result\n\n### Extra arguments\n\nAggregate functions can accept additional arguments beyond the first value expression. When called as `my_agg(expr, arg2, arg3)`, the extra arguments (`arg2`, `arg3`) are evaluated once before iteration and forwarded to all three callbacks:\n\n* `initialize(ctx, ...extraArgs)` — receives extra args after the context table\n* `iterate(state, value, ctx, ...extraArgs)` — receives extra args after the context table\n* `finish(state, ctx, ...extraArgs)` — receives extra args after the context table\n\nThis allows parameterized aggregates, for example a separator argument for string concatenation or boundary arguments for clamped sums.\n\n## aggregate.update(spec)\n\nUpdates an existing aggregate definition. Same keys as `aggregate.define`. Only the provided keys are overwritten; set a key to `config.unset` to remove it (e.g. `finish = config.unset`). Unlike other `*.define` APIs, `aggregate.define` still replaces the whole definition.\n\n## aggregate.alias(name, target, description?)\n\nCreates an alias so that `name` resolves to `target` at query time. The target may be a builtin, a user-defined aggregate, or another alias (chains are followed with cycle detection).\n\n```lua\naggregate.alias(\"total\", \"sum\")\naggregate.alias(\"stdev\", \"stddev_pop\", \"My stddev alias\")\n```\n\n# Examples\n\n## Define a custom aggregate with one extra argument\n\nDefine a custom aggregate `concat` that concatenates strings with a configurable separator (defaulting to `\", \"`):\n\n```lua\naggregate.define {\n  name = 'concat',\n\n  initialize = function(ctx, sep)\n    return { sep = sep or ', ', parts = {} }\n  end,\n\n  iterate = function(state, value)\n    if value ~= nil then\n      state.parts[#state.parts + 1] = tostring(value)\n    end\n    return state\n  end,\n\n  finish = function(state)\n    return table.concat(state.parts, state.sep)\n  end,\n}\n```\n\nUsage in a query:\n\n```lua\nquery [[\n  from p = data\n  group by p.category\n  select {\n    cat        = key,\n    names      = concat(p.name),\n    names_dash = concat(p.name, \" - \")\n  }\n]]\n```\n\n## Define a custom aggregate with two extra arguments\n\nDefine a custom aggregate `clamp_sum` that sums non-null inputs and clamps the result to a `[min, max]` range:\n\n```lua\naggregate.define {\n  name = 'clamp_sum',\n  description = 'Sum of non-null inputs clamped to [min, max]',\n\n  initialize = function(ctx, lo, hi)\n    return { total = 0, lo = lo or -math.huge, hi = hi or math.huge }\n  end,\n\n  iterate = function(state, value)\n    if value ~= nil then\n      state.total = state.total + value\n    end\n    return state\n  end,\n\n  finish = function(state)\n    if state.total < state.lo then return state.lo end\n    if state.total > state.hi then return state.hi end\n    return state.total\n  end,\n}\n```\n\nUsage in a query:\n\n```lua\nquery [[\n  from\n    d = {\n      { dept = \"eng\",   hours = 12 },\n      { dept = \"eng\",   hours = 35 },\n      { dept = \"sales\", hours = 8  },\n      { dept = \"sales\", hours = 6  },\n    }\n  group by d.dept\n  select {\n    dept  = d.dept,\n    total = clamp_sum(d.hours, 0, 40),\n  }\n]]\n```\n\nHere `eng` sums to 47 but is clamped to `40`, while `sales` sums to `14` which is within range.\n\n## Update an existing aggregate\n\n```lua\naggregate.update {\n  name = 'count',\n  description = 'Custom count aggregate that counts even nils',\n\n  iterate = function(state, value)\n    return state + 1\n  end,\n}\n```\n\n## Create an alias\n\n```lua\naggregate.alias(\"total\", \"sum\")\naggregate.alias(\"stdev\", \"stddev_pop\", \"Shorthand for population stddev\")\n```\n\n# Implementation\n\n```space-lua\n-- priority: 50\naggregate = aggregate or {}\n\nlocal aggregateSchema = {\n  type = 'object',\n\n  required = {\n    'name',\n    'initialize',\n    'iterate'\n  },\n\n  properties = {\n    name = schema.string(),\n    description = schema.string(),\n    initialize = schema.func(),\n    iterate = schema.func(),\n    finish = schema.func(),\n  }\n}\n\n--- Defines a new aggregate function for use in queries as `name(expr, ...)`, replacing any existing definition with the same name.\n--- @param spec table { name: string, initialize: function(ctx, ...), iterate: function(state, value, ctx, ...), finish?: function(state, ctx, ...), description?: string }; extra query arguments are passed after `ctx`\nfunction aggregate.define(spec)\n  local validationResult = jsonschema.validateObject(aggregateSchema, spec)\n\n  if validationResult then\n    error('aggregate.define: ' .. validationResult)\n  end\n\n  config.setLuaValue({'aggregates', spec.name}, spec)\nend\n\n--- Merges `spec` into an existing aggregate definition; set a key to `config.unset` to remove it.\n--- @param spec table { name: string } plus any keys accepted by `aggregate.define`\nfunction aggregate.update(spec)\n  if not spec.name then\n    error('aggregate.update: name is required')\n  end\n\n  local existing = config.get({'aggregates', spec.name}, {})\n\n  for k, v in pairs(spec) do\n    if v == config.unset then\n      existing[k] = nil\n    else\n      existing[k] = v\n    end\n  end\n\n  if not existing.initialize then\n    error('aggregate.update: aggregate '\n      .. spec.name ..

Each installed space appears once in the share sheet. SilverBullet then shows an editable draft and discovers actions with the `capture` service selector. Changes to Space Lua actions appear when Space Lua reloads.\n\nThe `match` function receives `id`, `receivedAt`, `title`, `text`, `url`, and `files`. Each file has a `handle`, `name`, `type`, and `size`; file bytes are omitted during discovery. Return `nil` to hide an action for this draft or a table with `name`, `description`, and optional `priority` to offer it.\n\n```lua\nservice.define {\n  selector = \"capture\",\n  match = function(data)\n    if data.text == \"\" then return nil end\n    return { name = \"Save shared text\", description = \"Create a page from the shared text\" }\n  end,\n  run = function(data)\n    space.writePage(\"Inbox/Shared \" .. data.id, data.text)\n  end,\n}\n```\n\nAn action's `run` function receives the edited draft. Within `run`, `capture.readFile(handle)` returns the file bytes and `capture.saveFile(handle, path)` writes a document after checking the path and size. Handles work only while that capture action is running. `saveFile` returns `true` when it creates a file, returns `false` when identical bytes already exist, and rejects a conflicting file.

It returns the same kind of value as a `${...}` directive: either a string (rendered as markdown), or a widget table such as one created with [[^Library/Std/APIs/Widget|widget.new{}]] or `widget.sandbox{}`.\n\nLua code widgets render through the same pipeline as `${...}` directives, so they get the same ⋯ menu (Edit source, Copy as Markdown) and re-run when what they read changes. Copy as Markdown copies the rendered `markdown`; widgets with only HTML have none.\n\nExample rendering a string as markdown:\n\n```lua\ncodeWidget.define {\n  language = \"greet\",\n  render = function(bodyText, pageName)\n    return \"Hello, **\" .. bodyText .. \"**!

For a ` ```#tag ` block, the first match wins: the tag's own `renderDataBlock`, then a code widget for `#tag` defined here, then the `data` tag's `renderDataBlock` (the form), then the plain YAML.

Results are sorted by page, UTF-16 position, and target identity. The returned table contains `recipient` (when filtered), `mentions`, `total` (before pagination), and `truncated` (more matches remain after this page).\n\nEach entry has `kind` (`mention` or `page`), `page`, `ref`, `target`, `snippet`, `by` (author names), and optional `replyTo`. Inline mentions also carry `range`, `pos`, `nickname`, `fromTag`, and `inComment`. `replyTo` is the first signed author, falling back to the current user's identity; it is absent when neither is known. Page-level recipients use that fallback; inspect page authorship before replying. Authorship is self-declared, not authenticated identity.

See [API/tag](https://silverbullet.md/API/tag) for use cases and longer examples.\n\n# API\n\n## tag.define(spec)\nDefines a tag, or extends an existing definition. Put `tag.define` calls in your `Library/Config` page so they are in place when the index runs.\n\n`spec` is a table with these fields, all optional except `name`:\n* `name` (string): the tag's name, without `#`.\n* `tagPage` (string): the page to open when clicking the tag. Defaults to `tag:<name>`.\n* `schema` (table): a [JSON Schema](https://silverbullet.md/Schema) the tag's objects are validated against. Build it with the [[^Library/Std/APIs/Schema|schema]] helpers. Validation failures show as lint warnings in the editor.\n* `mustValidate` (boolean): when `true`, objects that fail `schema` or `validate` are not indexed. Defaults to `false`.\n* `validate` (function `function(object)`): custom validation; returns `nil` when valid, or an error message.\n* `icon` (string): a [Feather](https://feathericons.com) icon name for the tag itself, shown in the Workbench. Unlike `pageDecoration`, it doesn't decorate the tag's pages; when it's absent, `pageDecoration.icon` is used.\n* `pageDecoration` (table): a [page decoration](https://silverbullet.md/Page%20Decorations) (`icon`, `prefix`, `cssClasses`, …) for every page with this tag. A page's own `pageDecoration` wins, then the first of its tags that sets a field; `cssClasses` from all of them combine. Changing it re-indexes the pages with the tag.\n* `transform` (function `function(object)`): called for each indexed object with this tag. Change the object and return it, return `{}` to skip indexing it, return `nil` to index it unchanged, or return a list of objects to index instead (one of which must keep the original `ref`).\n* `metatable` (table): a Lua metatable set on the tag's objects, e.g. to add computed attributes via `__index`.\n* `renderFrontmatter` (function `function(pageMeta, ctx)`): renders the frontmatter of pages with this tag as a widget. See [[#Rendering objects]].\n* `renderDataBlock` (function `function(object, ctx)`): renders each object of a ` ```#name ` data block as a widget. See [[#Rendering objects]].\n\nCalling `tag.define` again with the same `name` merges the new fields into the existing definition, so you can extend built-in tags. Set a field to `config.unset` to remove it.\n\n## tag.setRequired(name, attribute, required)\nMakes `attribute` required (`true`) or optional (`false`) in the schema of tag `name`, keeping the other required attributes. It runs whenever configuration loads, so requirements a library or built-in tag adds later are kept rather than frozen. The Workbench's Data tab writes these calls when you change whether an attribute is required.\n\nExample:\n\n```lua\ntag.define {\n  name = \"person\",\n  schema = {\n    type = \"object\",\n    properties = {\n      email = schema.string(),\n      manager = schema.ref(\"person\"),\n    },\n  },\n  pageDecoration = { icon = \"user\" },\n}\n```\n\n### Rendering objects\n`tag.define` can render a tag's objects as a custom widget in the editor, in place of their YAML. Each kind of object has its own hook:\n* `renderFrontmatter = function(pageMeta, ctx)` for a page's frontmatter\n* `renderDataBlock = function(object, ctx)` for each document of a ` ```#name ` data block.\n\nBy default both render [[^Library/Std/Widgets/Object Form]].\n\nThe first argument is the object with its current, possibly unsaved values: a page's frontmatter plus its name in `pageMeta.name`, or a data object's YAML plus `ref`, `tag`, `tags` and `page`. `ctx` is the render context: the raw YAML (`ctx.values`, `ctx.types`, `ctx.keys`), `ctx.kind` (`\"page\"` or `\"data\"`), `ctx.readOnly`, and `ctx.set(key, value)`, `ctx.remove(key)` and `ctx.move(key, delta)` to change it. See [Live Edit](https://silverbullet.md/Live%20Edit#The%20render%20context) for what each field holds, how errors and undo work, and an example.\n\n```lua\ntag.define {\n  name = \"team\",\n  renderFrontmatter = function(pageMeta)\n    return widget.htmlBlock(dom.div {\n      class = \"team-header\",\n      pageMeta.name .. \" · \" .. (pageMeta.status or \"Unknown status\"),\n    })\n  end,\n}\n```\n\nFor frontmatter, the first tag in the page's `tags` field with a `renderFrontmatter` wins, and pages without one fall back to the renderer of the `page` tag. For a ` ```#name ` block, the first match wins: the `name` tag's `renderDataBlock`, a code widget for `#name` (see [[^Library/Std/APIs/Code Widget]]), the `data` tag's `renderDataBlock`, then plain YAML. A block with several YAML documents (separated by `---`) shows one widget per document. Without any renderer, the YAML shows as plain text. The `liveEdit.frontmatter` and `liveEdit.dataBlocks` settings turn off the default form (the `page` and `data` renderers) without affecting a tag's own renderer.\n\n## tags.<name>\nShortcut for `index.objects(\"<name>\")`: all indexed objects with that tag.\n\n# Implementation\n\n```space-lua\n-- priority: 50\n-- boot: true\ntag = tag or {}\n\n--- Defines a tag, or merges `spec` into an existing definition with the same name.\n--- @param spec table { name: string, tagPage?: string, schema?: table, mustValidate?: boolean, validate?: function(object), transform?: function(object), metatable?: table, renderFrontmatter?: function(pageMeta, ctx), renderDataBlock?: function(object, ctx) }; set a field to config.unset to remove it\n--- @see API/tag\nfunction tag.define(spec)\n  local fields = {}\n  local metatable = nil\n  for k, v in pairs(spec) do\n    if k == \"metatable\" and v ~= config.unset then\n      metatable = v\n    else\n      fields[k] = v\n    end\n  end\n  config.merge({\"tags\", spec.name}, fields)\n  if metatable then\n    config.setLuaValue({\"tags\", spec.name, \"metatable\"}, metatable)\n  end\nend\n\n--- Makes `attribute` required or optional in the schema of tag `name`, keeping its other required attributes.\n--- @param name string the tag's name\n--- @param attribute string the attribute\n--- @param required boolean whether it is required\n--- @see API/tag\nfunction tag.setRequired(name, attribute, required)\n  local path = {\"tags\", name, \"schema\"}\n  local schema = config.get(path)\n  if not schema then\n    config.set(path, { type = \"object\" })\n    schema = {}\n  end\n  local list = {}\n  for _, n in ipairs(schema.required or {}) do\n    if n ~= attribute then\n      table.insert(list, n)\n    end\n  end\n  if required then\n    table.insert(list, attribute)\n  end\n  -- An empty Lua table would read back as an object, not an empty list\n  config.set({\"tags\", name, \"schema\", \"required\"}, #list > 0 and list or config.unset)\nend\n\n-- Set up tags.* short cut via meta tables\ntags = setmetatable({}, {\n  __index = function(self, tag)\n    return index.objects(tag)\n  end\n})\n```\n"},{"path":"Library/Std/APIs/Task State.md","lastModified":1794685544000,"text":"#meta/api\n\nImplements APIs for defining custom task states.

SilverBullet Markdown. Read before writing page content others will read. Not needed to read pages, to edit a space-lua block, or to add a query or widget call such as ${...} to a page (use Space Lua, Querying or Building Interfaces).\ntags: meta/skill\n---\nSilverBullet stores pages as plain Markdown. Keep prose useful when read outside SilverBullet, and preserve the style the space already uses: read a few neighboring pages (or the space's operating manual, if it has one) before writing.\n\n# Pages and links\nA file `Projects/Orchard.md` is the page `Projects/Orchard`. The `read`, `write` and `edit` tools take the page name; page APIs and wiki links omit the `.md` suffix. Wiki links are rooted at the space root, regardless of the directory of the page containing them.\n\n* `[[Projects/Orchard]]` links to a page.\n* `[[Projects/Orchard|the project]]` adds a label.\n* `[[Projects/Orchard#Decisions]]` links to a heading.\n* `[[Projects/Orchard@123]]` is a position reference. Positions are UTF-16 offsets and move when the page is edited.\n\nBacklinks are computed: do not maintain duplicate backlink lists. Renaming a page with the editor's `Page: Rename` command (or by editing the page name in the top bar) updates all references to it. Creating a page under a new name with `write` and deleting the old one does not, so for a rename ask the user to use the rename command, or find inbound links with a `lua` query (see the Querying page) and update them deliberately.\n\nUse ATX headings (`#`, `##`). The page name already is the title, so start with a summary and keep `#` for sections. Prefer `*` bullets and one source line per prose paragraph; do not hard-wrap. These are authoring defaults, not parser requirements, so match what the space does. Use frontmatter delimiters for YAML rather than decorative horizontal rules.\n\n# Frontmatter, tags and attributes\nFrontmatter must be the very first thing in the file. Its keys become page attributes. The file name determines the page `name`; never override it in YAML.\n\n```markdown\n---\ntags: project active\nstatus: planning\nowner: Mira\nrelated:\n  - \"[[Garden Notes]]\"\n---\nOrchard tracks the planting proposal.\n\n# Next steps\n* [ ] Draft a planting map #work [priority: high]\n* [x] Inventory tools #work\n```\n\nWhen creating a set of similar pages (people, incidents, books), give every page of that kind the same tag, such as `tags: incident`, not just similar attributes. The tag is what makes the class queryable with `index.pages(\"incident\")`. Space-separated bare names are the usual frontmatter convention; YAML arrays also work. Quote wiki links in YAML values, and quote any value containing a colon followed by a space: unquoted, it is invalid YAML.\n\nWhere a hashtag sits decides which object receives it. A paragraph holding only hashtags gives those tags to the page. A hashtag in ordinary prose tags its paragraph, and one on a list item or task tags that object. Contained objects may also inherit tags from their page: query results distinguish explicit `tags` from inherited `itags`.\n\nInline `[key: value]` attributes attach structured values to the object that contains them:\n\n```markdown\nA measured observation. [confidence: 0.8]\n\n* Use the northern beds #decision [status: accepted]\n* [ ] Check drainage [due: \"2026-10-01\"]\n```\n\nTasks expose `done` and `state` in the index. Keep custom task states and nesting as they are; do not assume every non-blank checkbox means completed.\n\n# Mentions and authorship\n`@name` addresses an identity. A trailing `-- @name` (also with an em or en dash) signs the block instead of addressing anyone. A signature must end its line, and it does not create another inbox item. A single hyphen or `(@name)` is not a signature.\n\n```markdown\n@helper Please check the planting dates. -- @mira\n```\n\nFrontmatter `recipients: [\"helper\"]` addresses the whole page, and `authors: [\"mira\"]` credits it. Page authorship does not sign every unsigned mention in the body. In an owner-only space `@self` addresses the owner. Signatures are self-declared prose, not proof of identity. See the Mentions page for working an inbox.\n\n# Dynamic content and code\nAn expression in dollar-brace delimiters evaluates Space Lua when the page renders and shows its value. A `space-lua` fence defines executable, space-wide code, and a `space-style` fence defines CSS. Both load only from pages under `Library/`. Outside those, a `space-lua` or `space-style` fence is an inert example, the same as a plain `lua` fence, which is always a displayed example that is never installed as a script. Writing `space-lua` fences or live expressions into a page changes what the space runs, so only do it when asked, and read the Space Lua page first.\n\n````markdown\n```space-lua\norchard = orchard or {}\nfunction orchard.label()\n  return \"Planting plan\"\nend\n```\n````\n\nQueries inside Lua look like `query[[from p = index.pages() limit 5 select p.name]]`; in Markdown, wrap such a call in a dollar-brace expression and it renders as a live table (the Querying page shows the pattern). Keep essential facts in ordinary prose rather than only in computed output, so the page still reads well elsewhere. Do not evaluate untrusted page code just to read or summarize it.\n\nTo give every page with a tag its own look, see the Building Interfaces page.\n"},{"path":"Library/Std/Docs/Querying.md","lastModified":1794685544000,"text":"---\ndescription: Answering questions about pages, tasks, tags and attributes with SLIQ queries and search, and putting a live query table in a page. Read before running a query through the lua tool, adding or fixing a query in a page, or when search results seem wrong.\ntags: meta/skill\n---\nUse the `lua` tool to query the space's index: an expression returns its value, so `query[[...]]` on its own works. The syntax is SLIQ (Space Lua Integrated Query); a summary is at the end of this page.\n\n# Sources\n| Source | Selection |\n| --- | --- |\n| `index.pages(\"project\")` | Pages tagged project (no argument: all pages) |\n| `index.contentPages()` / `index.toolPages()` | Content pages / tool pages (pages under `Library/`) |\n| `index.tasks(\"work\")` | Tasks tagged work |\n| `index.items(\"decision\")` | List items tagged decision |\n| `index.headers()`, `index.paragraphs()`, `index.tables()`, `index.data()` | Headings, paragraphs, table rows, data-block objects |\n| `index.objects(\"topic\")` | Any object carrying that tag |\n| `index.tags()` | Tag objects |\n| `index.relations(\"mention\")` | Links (`mention`), `@name` mentions (`at-mention`), or attribute edges by key |\n| `index.aspiringPages()` | Linked page names that do not exist |\n\nCustom frontmatter is page data; inline attributes belong to the enclosing object. Explicit tags (`tags`) and inherited tags (`itags`) differ.\n\n```lua\nquery[[\n  from p = index.pages(\"project\")\n  where p.status == \"planning\"\n  order by p.name\n  limit 20\n  select {page = p.name, owner = p.owner}\n]]\n```\n\nAlways write `from` with an iterator variable: `from p = index.pages(\"project\")`, then `p.status`, `p.name`.\n\n# Answer from the data\nFor a question about the space's data (counts, totals, rankings, \"which\"), query it: one query with `group by` beats reading pages one by one. Pages often already hold the query you need: `read` them with `rendered: true` to get the evaluated results and their links in one call, and follow those links rather than querying again.\n\n# A live table in a page\nIn page Markdown, a query inside a dollar-brace expression renders as a table and updates by itself when the pages it reads change:\n\n```markdown\n${query[[from p = index.pages(\"book\") where p.status == \"unread\" order by p.name select {Book = markdown.link(p), Author = p.author}]]}\n```\n\nThe `markdown.link(p)` column makes each name a link to its page (for other objects it links by `ref`). Write this into the page with `write` or `edit`; it is Markdown, not a `space-lua` block. For a list instead of a table, select a template such as `templates.pageItem(p)` (see the Templates page). Reach for a widget only when the table needs a filter box, selection or actions (see Building Interfaces).\n\nCheck your work: read the result of the `write`/`edit` (it reports script load errors), then `read` the page with `rendered: true` (evaluated output plus lint problems), then take a `screenshot` when the look matters.\n\n# Fixing a broken query or page\n1. Get the actual error first: `read` the page with `rendered: true` (it lists lint problems and failing expressions), or run `space.lint(\"Page\")` with `lua`.\n2. Run the failing expression on its own with `lua`, and change one thing at a time.\n3. Report the error you saw and the change that fixed it.\n\nDo not call a construct invalid without running it. Existing pages may use forms you would not write yourself: `index.tag \"topic\"` and `tags.topic` are both aliases of `index.objects(\"topic\")` and valid. Keep them unless they are the cause.\n\n# Why a query fails or returns nothing\n* Compare with `==`, never `=`: a single `=` in `where` is a syntax error. Use `~=`, `and`, `or`, `not`, not SQL or JavaScript operators.\n* Sample before querying: `query[[from t = index.tasks() limit 3 select t]]` shows the real field names. Custom attributes exist only on some objects; a missing field is null, not an error.\n* Always add `limit` while exploring: a bare collection such as `index.pages(\"book\")` returns at most 1000 rows, then a `\"<truncated: ...>\"` entry, and functions show up as markers like `\"<function>\"`. Fields you do not see in a sample may exist on other objects, so sample the relevant tag or pages.\n* There is no `contains`. Test a substring with `s:find(\"x\", 1, true)` (nil when absent), prefixes and suffixes with `s:startsWith(\"x\")` and `s:endsWith(\"x\")`, and membership with `table.includes(t, value)`.\n* Results are distinct: rows equal after `select` appear once. `select {status = t.status}` yields one row per status. Count with `group by` and `#group`, or keep an identifying field such as `ref` in the row.\n* `query[[...]]` must be parenthesized before indexing: `(query[[...]])[1]`. A literal `]]` cannot appear inside the brackets; use `query[==[ ... ]==]`.\n* The index updates asynchronously. Right after an edit a narrow query may miss it; an empty result from a stale index is not evidence that nothing matches.\n\nKeep `ref` in rows so an answer can point back to its source. If you fall back to reading Markdown because the index is unavailable, say the result comes from reading files, not from an exhaustive index query. A limit gives a partial answer: if completeness matters, count first or page with `order by` plus `limit` and `offset`. Do not put mutations in a query.\n\n# Tasks\nTasks have `done` (true when checked), `state` (the text between the brackets, for custom states) and `page`. There is no built-in due date: spaces usually add an inline attribute such as `[due: \"2026-10-01\"]`. ISO date strings compare as text, so `where not t.done and t.due and t.due <= date.today()` finds overdue tasks.\n\n# Reading the source and searching\nA query result is an index snippet, not the page: to answer from content, `read` the page and quote from it. The index is not full-text search: use the `search` tool for names, phrases and wording, and SLIQ for structure.\n\nSemantic search (meaning, other wording, related pages) is a free feature of Server and Desktop, on in spaces where a model was chosen. Check `search.status()` first (it returns `{backend, model, capabilities = {modes, related}, ready, progress, reason}`, and a `reason` while `ready` is true is a warning, not a failure): semantic search is available when `capabilities.modes` contains `natural`, related pages when `capabilities.related` is true, and `reason` says why not. Do not choose a model, change settings or start a download because it is missing.\n\n```lua\nsearch.find(\"soil drainage\", {mode = \"natural\", limit = 10})\n```\n\n`search.find` and `search.related(\"Garden Notes\", {limit = 10})` return `{items, total, partial, notice}`; each item has `page`, `line`, `heading` and `excerpt`. `pos` is the match's position in the page, and `highlights` are `[start, end]` UTF-16 offsets into `excerpt`. `partial` or `notice` means the index is still building, which is not an empty result. `mode = \"words\"` (all words) and `mode = \"phrase\"` (exact phrase) are the full-text modes, offered when `capabilities.modes` lists them (the MCP `search` tool's `semantic` is `natural` here), better for names, codes and exact wording than `natural`; `scope` (`pages`, `meta` or `all`) narrows any of them. `search.related` returns one item per page, best first, and raises an error while related pages are unavailable or when the page is not in the semantic index yet. Always pass the page name: the runtime's current page need not be the one the user sees. Without semantic search, fall back to full-text search or SLIQ and say the coverage is narrower.\n\n# Syntax summary\n```lua\nquery[[\n  from p = index.pages(\"project\")      -- required; any collection, also a Lua table\n  where p.status ~= \"done\"             -- filter rows\n  group by p.owner                     -- rows become {key, group}\n  having #group > 1                    -- filter groups\n  order by count desc                  -- asc | desc | using cmp, nulls first|last; commas for more keys\n  limit 10, 20                         -- limit n[, offset]; or a separate offset n\n  select {owner = key, count = #group}\n]]\n```\n\nClauses may come in any order; only `from` is required. `order by` may use an alias from `select` only together with `group by` (as in the example above, wherever `order by` sits relative to `select`); without `group by` the alias is not visible and the sort silently does nothing, so order by the row expression instead (`order by p.size desc select {name = p.name, size = p.size}`). After `group by`, `key` is the group key (a table `{key[1], key[2]}` for several keys) and `group` the array of rows. Aggregates work in `select` and `having`, with or without `group by` (without it the whole result is one group): `count`, `sum`, `min`, `max`, `avg`, `array_agg`, `string_agg` and more (`index.aggregates()` lists them). They take an inner `order by` and a filter: `array_agg(p.name order by p.name)`, `count(p.size) filter(where p.size > 100)`. Projections: `select p.name`, `select {name = p.name}`, `select table.select(p, \"name\", \"tags\")`.\n\nCommon queries: backlinks with `from r = index.relations(\"mention\") where r.to == \"Garden Notes\" select r.page`; recent pages with `from p = index.pages() order by p.lastModified desc limit 10 select p.name`.

Ordinary system Lua is not a substitute for testing it. The `lua` tool runs it inside the space's runtime: an expression returns its value, and anything else runs as a script, which should end with `return` to give a result.\n\n# The loop\n1. **Discover.** Do not guess API names or signatures. List what exists, then describe a function.\n2. **Write.** Put the code in a `space-lua` fence on a page under `Library/`, using `edit` or `write`. Blocks on any other page do not run.\n3. **Check your work:** read the result of the `write`/`edit` (it reports script load errors), then `read` the page with `rendered: true` (evaluated output plus lint problems), then take a `screenshot` when the look matters.\n\nA `write` or `edit` (MCP or `sb`) of a page holding `space-lua` or `space-style` reloads the scripts at once, and the result says either that they reloaded without errors or lists the page's load errors and lint problems. You do not need to reboot. After changing files any other way, including `space.writePage` from `lua`, call `system.reboot()` to reload. Repeat until the result is clean and the page looks right.\n\n# Discover\n```lua\nspacelua.listFunctions(\"editor\")\n```\n\n```lua\nspacelua.describe(\"editor.getText\")\n```\n\n```lua\nspacelua.renderApiDocumentation(\"editor\")\n```\n\n`describe` takes a function or dotted function name and returns parameters, results, examples and `see` links. A nil result means the name is not a recognized function, not permission to invent parameters. `listFunctions()` with no argument lists documented global functions, and `table.keys(_G)` lists all global names, namespaces included. Use `system.listCommands()` to see registered commands. `spacelua.describe(\"editor\")` does not describe a namespace; use `listFunctions` or `renderApiDocumentation` for that, and follow the returned `see` links to the documentation. Capabilities vary by version and by installed libraries. The SilverBullet documentation (docs.silverbullet.md; edge.silverbullet.md for Edge builds) has an `API/<namespace>` page for each namespace, such as `API/editor`.\n\n# Write\nFenced `space-lua` blocks load only from pages under `Library/`; a block anywhere else is an inert example and gets the lint warning \"Not loaded\". Each block is its own chunk: a `local` in one block is invisible to the others. Global assignments and named global functions are shared across the space. Start every block that extends a namespace with `ns = ns or {}`, and give the block that defines the namespace `-- priority: N` if others depend on it (higher loads earlier). Use priorities only for real dependencies.\n\n````markdown\n```space-lua\norchard = orchard or {}\n\nfunction orchard.openTasks()\n  return query[[from t = index.tasks() where not t.done and t.page == \"Projects/Orchard\" select t.name]]\nend\n\ncommand.define {\n  name = \"Orchard: Show Open Tasks\",\n  run = function()\n    editor.flashNotification(#orchard.openTasks() .. \" open tasks\")\n  end\n}\n```\n````\n\nOther registrations follow the same shape:\n\n```lua\nslashCommand.define { name = \"planted\", run = function() editor.insertAtCursor(\"Planted on \" .. date.today()) end }\nevent.listen { name = \"orchard:changed\", run = function(e) print(e.data) end }\nconfig.define(\"orchard.beds\", { type = \"number\", default = 4 })\nconfig.set(\"orchard.beds\", 6)\n```\n\n`config.set` changes the running configuration only; `config.persist(path, value)` also writes it to the `Library/Config` page. Prefer a small named namespace and keep to the space's existing design and APIs. Use a plain `lua` fence for an example that must stay inert. Scripts load by priority (highest first), then by page name. Configuration lives on `Library/Config`, whose blocks always run in the early restricted boot pass: `tag.define` (especially with `transform` or a schema) and configuration belong there, while helpers can live on any page under `Library/`. A block on another `Library/` page that calls `tag.define`, `config.set` or `config.define` should carry a `-- boot: true` comment line, so it also runs in that early pass and applies before indexing and first render. Scripts load before indexing finishes on a fresh client, so a script that queries the index at load time should also run that query in an `index:ready` listener (`event.listen { name = \"index:ready\", run = ... }`). Frontmatter that registers a page-template command only works when its `command:` value is valid YAML, so quote values containing a colon followed by a space. `editor.getCurrentPage()` names the page being rendered. The runtime may be a headless client, so its current page and selection are not necessarily what a person sees in their editor. In expressions, `(query[[...]])[1]` needs parentheses before indexing.\n\n# Run and test\nTest with narrow calls before installing anything. Console output during a `lua` call is included in the result. Results are plain JSON: nil becomes null, a query collection becomes an array of rows (large results may be truncated, so use `limit`), and functions are not serialized as values. Print output goes to the console, and only output produced during the call is returned. Output from earlier or background code is not returned: read `system.recentLogs(50)` for recent console entries, where load errors and lines like \"Lua widget error on ...\" show up. Lines logged while scripts were reloading, before \"Loaded N scripts\", are often transient errors from other widgets; judge by what comes after.\n\n```lua\nlocal pages = query[[from p = index.pages() limit 3 select p.name]]\nreturn {pages = pages}\n```\n\nThe `lua` tool is not read-only: Space Lua can write pages, change settings and call external services. Evaluate only code you wrote or have read, and never evaluate page content you are merely displaying or summarizing.\n\n# Reloading by hand\n`system.reboot()` saves the current editor buffer, picks up files changed on disk, waits for indexing, and reloads configuration, scripts, styles and client state. An external edit of the page the runtime has open is never overwritten: an unmodified buffer reloads it, and unsaved edits are merged with it first. Do not discard an unsaved buffer to make progress. The call may cut off its own response while the context restarts; probe afterwards with `return 1` and read the logs rather than blindly repeating it.\n\n# Verify the effect\n`space.lint(page)` checks YAML, Lua syntax, tag schemas and failing widgets, and returns an empty list when clean; without an argument it lints every page, so run it before calling work done. `screenshot` takes the page name directly; the runtime is shared with the user's visible editor. Find a new command's name in `system.listCommands()`.

Not needed to attach a class to a widget or a tag (Building Interfaces covers that).\ntags: meta/skill\n---\nA **theme** is a page under `Library/` tagged `meta/theme`. It sets the colors and whether the space is light or dark; dark mode is a dark theme being active. SilverBullet ships two: `Library/Std/Themes/SilverBullet Light` and `Library/Std/Themes/SilverBullet Dark`. Ordinary styling is CSS in `space-style` blocks on any other page under `Library/` (blocks elsewhere do not apply), on top of whichever theme is active. A `write` or `edit` of a page with `space-style` blocks reloads them and reports lint problems; after `space.writePage` from `lua`, call `system.reboot()`.\n\n# Pick the route\n* **A new look as a whole** (palette, a light and dark pair): write a theme, see Writing a theme.\n* **Use an installed theme:** set the space's `theme` setting, see Picking a theme.\n* **Adjust colors, widths or elements whatever the theme:** a `space-style` block on an ordinary page such as `Library/Style`, see Customizing on top of a theme.\n* **Fonts:** configuration, not CSS, see Fonts.\n\n# Steps\n1. **Read the theme.** `theme.getActive()` names it; list its variables (snippet under Variables). Most colors are a variable away: set the variable before reaching for a selector.\n2. **Inspect each element you will style** before writing CSS for it: its classes, computed styles and parent chain (snippet under Inspecting an element). Inherited fonts, negative margins and wrapper classes show up here, and only by accident in a screenshot.\n3. **Write the block** or the theme page, with the variables and selectors below.\n4. **Check it.** The `write`/`edit` result lists lint problems (theme frontmatter included); fix them. `read` the page with `rendered: true`, take a `screenshot` in a light and in a dark theme (see Checking light and dark), and run the inspection snippet again on every element you targeted.\n\nDone when the write result is clean, both screenshots look right, every targeted element's computed styles show your values, every editor line you gave vertical spacing (headings, `.cm-line`) shows `margin: 0px` with the spacing in its padding (see Editor specifics), and `theme.getDeviceTheme()` is back to what it was before you started.\n\n# Picking a theme\nSilverBullet shows the first of these that names an installed theme:\n1. **This device's choice**: `theme.setDeviceTheme(page)`, or `nil` to clear it. `theme.getDeviceTheme()` reads it. It is stored per client, and the `lua` runtime's client may be the user's own: on SilverBullet Desktop it shares the editor's storage, so a switch from `lua` changes the user's device theme for that space. Before switching, record `theme.getDeviceTheme()`, and afterwards restore exactly that value.\n2. **The space's `theme` setting**, for every device: `config.persist(\"theme\", \"Library/Std/Themes/SilverBullet Dark\")` with `lua`, which writes it into the managed block of `Library/Config` (the one Configuration → Appearance → Theme edits). Change it only when the user asks for a different theme.\n3. SilverBullet Light, or SilverBullet Dark when the system prefers dark.\n\n`theme.list()` returns the installed themes, each with `page`, `displayName`, `scheme` (`light` or `dark`) and, when set, `description`, `counterpart` and `fonts`. A theme is identified by its page name; one renamed or removed is skipped.\n\n# Writing a theme\n````markdown\n---\ntags: meta/theme\ndisplayName: Sepia\ndescription: Warm paper with brown ink.\nscheme: light\nfonts:\n  editor: inter\n---\n```space-style\nhtml {\n  --root-background-color: #f6efe2;\n  --root-color: #3b3024;\n  --subtle-color: #8a7a66;\n  --ui-surface-border-color: #e0d4bf;\n  --ui-accent-color: #a8432f;\n  --link-color: #8c3b2a;\n}\n```\n````\n\n* **Place it** under `Library/`, for example `Library/Themes/Sepia`. The page name is the theme's identity: the space setting and device choices store it, so renaming it resets them.\n* **Frontmatter:** `scheme` (`light` or `dark`) is required: without a valid one the page is not a theme, it is missing from `theme.list()`, and its `space-style` blocks apply nowhere (its `space-lua` still runs). The lint error on `scheme` is the only signal. `displayName` and `description` show in pickers. `counterpart` is a quoted wiki link to its light or dark sibling, such as `counterpart: \"[[Library/Themes/Sepia Night]]\"`, which **Theme: Toggle Light/Dark** switches to; the sibling is its own theme page with its own `scheme` and a `counterpart` pointing back. `fonts` suggests fonts (see Fonts). The tag has a schema, so a wrong `scheme` or a `fonts.editorSize` outside 10 to 48 is a lint problem in the write result.\n* **Every `space-style` block on the page belongs to the theme** and applies only while it is active. A `space-lua` block on it runs always, like on any `Library/` page.\n* **Set base variables in a plain `html { … }` rule.** The theme starts from the built-in theme with the same `scheme` (SilverBullet Dark for a dark one), and SilverBullet's defaults have zero specificity, so `!important`, `:root` and `[data-sb-scheme]` selectors are never needed in a theme.\n* **Prefix variables of your own** with the theme's name (`--sepia-ink`).\n* **Strong accent:** hashtag pills and the selected completion fill with `--ui-accent-strong-color` and write on it in `--ui-accent-strong-contrast-color`, which assumes the fill comes out dark. With a very light accent, set both.\n\nAfter the write, `theme.list()` includes it. Switch to it with `theme.setDeviceTheme(page)` to check it, and look at a page with a table, code, frontmatter and hashtags, the command palette and a notification: most derived colors show there.\n\n# Variables\nThemes and styles work by setting CSS custom properties on `html`. **Base variables** are the palette; nearly every other (**specific**) variable derives from them: the top bar mixes the page and subtle colors, alerts and notifications use the tones, hashtags and the selected completion use the strong accent. Set base variables first, and a specific one only when its derived color does not work.\n\nThe base variables:\n* Surfaces and text: `--root-background-color`, `--root-color`, `--subtle-color`, `--subtle-background-color`, `--ui-surface-border-color`.\n* Accent: `--ui-accent-color`, `--ui-accent-contrast-color`, `--ui-accent-strong-color`, `--ui-accent-strong-contrast-color`.\n* Links and meta: `--link-color`, `--link-missing-color`, `--link-invalid-color`, `--meta-color`, `--meta-subtle-color`. Marks: `--highlight-color`.\n* Tones: `--tone-<name>` and `--tone-<name>-soft` for `success`, `warning`, `danger`, `info`, `neutral` and `accent`. They are also for your own styles and widgets: every theme gives them values that read on its background, so color with `var(--tone-danger)` rather than a fixed color, which needs checking in a light and a dark theme.\n* Code: `--editor-code-color` and `--editor-code-<part>-color` for `variable`, `typename`, `string`, `number`, `operator`, `atom`, `comment`.\n* Layout: `--editor-width`. Fonts (set through configuration): `--ui-font`, `--editor-font`, `--editor-monospace-font`, `--editor-font-size`.\n\nThe derivations are computed on `html`, so set base variables there: a base variable set on another element (`#sb-top { --root-color: red }`) changes that element but not the specific variables computed from it. Every variable, with its light and dark values and what it derives from, is on the `Theming/Variables` page of the SilverBullet documentation (docs.silverbullet.md; edge.silverbullet.md for Edge builds), and the selectors SilverBullet keeps stable are on `Theming/Selectors`. Any other class, id or structure may change between releases.\n\nThis lists the active theme's variables whose name contains `filter` (`\"\"` for all). A derived variable shows its formula with the base values filled in, such as `color-mix(in srgb, #3569b8, black 20%)`:\n\n```lua\nlocal filter = \"accent\"\nlocal cs = js.window.getComputedStyle(js.window.document.documentElement)\nlocal rows = {}\nfor i = 0, cs.length - 1 do\n  local name = cs.item(i)\n  if string.sub(name, 1, 2) == \"--\" and string.find(name, filter, 1, true) then\n    rows[#rows + 1] = name .. \": \" .. cs.getPropertyValue(name)\n  end\nend\ntable.sort(rows)\nreturn theme.getActive().page .. \"\\n\" .. table.concat(rows, \"\\n\")\n```\n\nTo compare with another theme, switch to it with `theme.setDeviceTheme(page)` first, and restore the device theme afterwards (see Checking light and dark).\n\n# Customizing on top of a theme\nOrdinary `space-style` blocks load after the theme, so a rule there beats the theme's rule for the same selector (or one as specific), whatever its `/* priority: N */` (priority orders ordinary blocks among themselves: highest first, so a lower priority loads later and wins ties). Target a rule at:\n\n```css\n/* Every theme */\nhtml {\n  --editor-width: 1000px;\n}\n\n/* Light or dark themes: data-sb-scheme is \"light\" or \"dark\" */\nhtml[data-sb-scheme=\"dark\"] {\n  --highlight-color: rgba(255, 200, 0, 0.35);\n}\n\n/* One theme, by the end of its page name */\nhtml[data-sb-theme$=\"/Sepia\"] {\n  --link-color: #8c3b2a;\n}\n```\n\nA color in a plain `html` rule applies in dark themes too, so give every color you set a `html[data-sb-scheme=\"dark\"]` value as well, or use a tone or another variable (`var(--tone-accent)`) that each theme already sets. Read `data-sb-scheme` and `data-sb-theme` in selectors and scripts; SilverBullet sets them from the active theme, so switch themes with the theme API rather than setting them. `data-theme` is a deprecated alias of `data-sb-scheme`.\n\nA look with a palette of its own is a theme, not a stack of overrides: write one instead.\n\n# Fonts\nFonts are configuration: `config.persist(\"fonts.editor\", \"inter\")` with `lua` (it writes the managed block of `Library/Config`, like Configuration → Appearance), with the keys `ui` (interface), `editor` (page text), `code` (monospace) and `editorSize` (pixels, 10 to 48). `table.keys(config.get(\"fonts.available\"))` lists the installed font keys; more come from font libraries. A theme only suggests fonts, with the same keys under `fonts` in its frontmatter; the space's own setting wins. Keep `--ui-font`, `--editor-font`, `--editor-monospace-font` and `--editor-font-size` out of CSS: theme and ordinary styles both load after the configured fonts, so setting them overrides the configuration (in a theme, with a lint warning).\n\n# Checking light and dark\n1. Record `theme.getDeviceTheme()` (a page name, or `nil`) and `theme.getActive()`.\n2. Switch to a dark theme: `theme.setDeviceTheme(\"Library/Std/Themes/SilverBullet Dark\")`, the active theme's `counterpart`, or the theme you are writing. Take a `screenshot`.\n3. Switch to a light theme the same way and take the second screenshot.\n4. Restore exactly what step 1 recorded: `theme.setDeviceTheme(recorded)`, which is `theme.setDeviceTheme(nil)` only when it was `nil`. On SilverBullet Desktop this is the user's own device theme.\n\n# Inspecting an element\nRun with `lua` on the page that shows the element (an empty result means nothing matched); change the selector:\n\n```lua\nlocal el = js.window.document.querySelector(\".sb-wiki-link\")\nlocal out = {}\nwhile el and #out < 6 do\n  local cs = js.window.getComputedStyle(el)\n  out[#out + 1] = el.tagName .. \" .\" .. tostring(el.className) .. \" | font: \" .. cs.fontFamily .. \" | margin: \" .. cs.margin .. \" | padding: \" .. cs.padding\n  el = el.parentElement\nend\nreturn table.concat(out, \"\\n\")\n```\n\nAdd other properties (`cs.color`, `cs.backgroundColor`, `cs.lineHeight`) as needed; these come out resolved, unlike variables. `document.elementFromPoint(x, y)` finds what sits at a spot in a screenshot.\n\n# Editor specifics\n* **Space editor lines with padding.** The editor works out which line a click hits from line heights, and margins are not part of a line's height, so vertical margin on a heading (`.sb-line-h1` to `.sb-line-h6`) or any `.cm-line` sends clicks below it to the wrong line, more so further down the page. `padding-top` and `padding-bottom` give the same look and keep clicks exact.\n* **Scope editor rules** with `#sb-main .cm-editor` so they do not leak into panels and widgets.\n* **Links carry negative side margins.** `.sb-wiki-link` (and `a.wiki-link` in rendered Markdown) has `padding: 0 5px; margin: 0 -5px` to widen its background without moving text.

Read before defining a tag or its schema. Not needed just to tag pages or query tagged objects (Markdown and Querying cover that).\ntags: meta/skill\n---\nEvery object in the index (page, task, item, data object) carries tags. Tagging needs no definition: `tags: book` in frontmatter is enough to make `index.pages(\"book\")` work. Define a tag with `tag.define` only to give it a schema, validation, computed attributes, a look, or a custom renderer.\n\n# Where it goes\nPut `tag.define` calls in a `space-lua` block on the `Library/Config` page (create it if missing), or on another page under `Library/`. Blocks on other pages do not run. `Library/Config` loads before pages are indexed, so a `transform` defined there sees every page. A block on a `Library/` page gets the same early run when it carries a `-- boot: true` comment line, and a block that calls `tag.define`, `config.set` or `config.define` should carry it so it applies before indexing and first render. Avoid names SilverBullet uses for its own objects: `page`, `task`, `item`, `paragraph`, `header`, `link`, `tag`, `data`, `table`, `anchor`, `relation`, `identity`, `document`. You can extend those, but not reuse them for your own kind.\n\n# tag.define fields\nAll optional except `name`:\n* `name`: the tag, without `#`.\n* `tagPage`: the page opened when clicking the tag (default `tag:<name>`).\n* `schema`: a JSON Schema the tag's objects are checked against. Failures show as lint warnings in the editor.\n* `mustValidate`: when `true`, objects failing `schema` or `validate` are not indexed at all (errors go to the log). Default `false`.\n* `validate`: `function(o)` returning nil when valid, or an error message.\n* `pageDecoration`: a look for every page with the tag: `icon` (a Feather icon name), `prefix`, `cssClasses`, and the other page decoration fields. The page's own `pageDecoration` wins, then the first of its tags that sets a field; `cssClasses` combine. Changing it re-indexes the pages with the tag automatically.\n* `transform`: `function(o)` called for each indexed object with the tag. Change `o` and return it; return `{}` to skip indexing it; return `nil` to index it unchanged; or return a list of objects to index instead, one of which keeps the original `ref`.\n* `metatable`: a Lua metatable for the tag's objects, e.g. computed attributes through `__index`.\n* `renderFrontmatter`: `function(pageMeta, ctx)` returning a widget that replaces the frontmatter of pages with this tag.\n* `renderDataBlock`: `function(object, ctx)` returning a widget for each object in a data block fenced as the tag.\n\nCalling `tag.define` again with the same `name` merges the fields, so you can extend built-in tags. Set a field to `config.unset` to remove it.\n\n```lua\ntag.define {\n  name = \"book\",\n  schema = {\n    type = \"object\",\n    properties = {\n      author = schema.string(),\n      rating = schema.nullable(\"number\"),\n      status = schema.enum({\"unread\", \"reading\", \"read\"}),\n      finished = schema.date(),\n      series = schema.ref(\"series\"),\n    },\n  },\n  pageDecoration = { icon = \"book\" },\n}\n```\n\nWithout writing Lua, the Workbench's Data tab (`Workbench: Schema`) shows a tag's attributes, creates a schema from the ones its objects use, and edits schemas in place, saving them to a managed block in `Library/Config`.\n\n# Schema helpers\nThe `schema` table builds JSON Schema values; a plain table such as `{type = \"string\"}` works too.\n\n| Helper | Accepts |\n| --- | --- |\n| `schema.string()`, `schema.number()`, `schema.boolean()`, `schema.null()` | That type |\n| `schema.array(\"string\")` or `schema.array(s)` | A list of a type name or a schema |\n| `schema.nullable(t)`, `schema.nullableArray(t)` | The type (or list of it) or null |\n| `schema.enum({\"a\", \"b\"})` | One of the listed strings |\n| `schema.date()` | A date string |\n| `schema.ref(\"series\")` | One quoted wiki link, such as `\"[[Series/Dune]]\"`, to an object with that tag (tag optional) |\n| `schema.tags(extra)`, `schema.identities(extra)` | Tag names or `@names`, as a list or one space-separated string; `extra` adds keys such as `description` |\n| `schema.object()`, `schema.func()`, `schema.schema()` | Markers for any object, a function, a schema |\n\nUse `type = \"object\"` with `properties` at the top, as above. The same helpers describe settings in `config.define(key, schema)`.\n\n# Check the result\nAfter saving `Library/Config`, check that the definition took effect and what it does:\n\n```lua\nindex.tagSchema(\"book\")\n```\n\n```lua\nspace.lint(\"Books/Dune\")\n```\n\n```lua\nquery[[from b = index.pages(\"book\") limit 3 select b]]\n```\n\n`index.tagSchema` returns the schema as loaded (nil when none is declared). `space.lint` lists schema violations on a page with `source` `objects`; run it on a page you expect to be invalid as well as one you expect to pass. The sample query shows attributes added by a `transform`.\n\nAn `edit` of `Library/Config` (MCP or `sb`) reloads its scripts and reports load errors, so a typo in `tag.define` shows up in that result. Then `read` a tagged page with `rendered: true` for its lint problems, and take a `screenshot` when the look matters.\n\n# Changing a transform\nA `transform` runs only when a page is indexed. A new or changed transform therefore applies to pages as they are next edited, not to the rest. To apply it everywhere, reindex the space: the `Space: Reindex` command, or `index.reindexSpace()` with `lua`. On a large space this takes a while, so tell the user, or ask before doing it. Schema and `validate` changes need no reindex for lint, but `mustValidate` filtering happens at index time.\n\n# Styling a kind of page\nTo give every page with a tag its own look, style the class instead of decorating each page by hand: attach a CSS class through the tag, then target it from a `space-style` block. Put both blocks on a page under `Library/`; they do not run elsewhere. Put the `tag.define` in `Library/Config`, for the reason given above.\n\n````markdown\n```space-lua\ntag.define {\n  name = \"recipe\",\n  pageDecoration = { icon = \"coffee\", cssClasses = { \"recipe-page\" } },\n}\n```\n\n```space-style\nbody.recipe-page #sb-main .cm-editor { border-left: 4px solid var(--tone-accent); }\n```\n````\n\nThe class lands on the page body, on links to the tagged pages and on their picker entries. Prefer the tone colors (`var(--tone-success)`, `warning`, `danger`, `info`, `neutral`, `accent`, each with a `-soft` variant) over fixed colors: every theme, light or dark, sets them to read well. Existing pages pick up a new class after a reindex (see above).\n\n# Rendering and style\n`renderFrontmatter` and `renderDataBlock` receive the object with its current values and a context `ctx` with `ctx.values`, `ctx.kind`, `ctx.readOnly` and `ctx.set(key, value)`, `ctx.remove(key)`, `ctx.move(key, delta)` to edit the YAML. For frontmatter, the first tag in the page's `tags` with a renderer wins. Full details and examples are on the `API/tag` page of the SilverBullet documentation (docs.silverbullet.md; edge.silverbullet.md for Edge builds).

Read before creating or changing any template. Not needed for a plain query table (Querying covers that).\ntags: meta/skill\n---\nA template is text with `${expression}` placeholders that Space Lua fills in when the template is used. Three kinds of template cover most needs: page templates create new pages, slash templates insert text at the cursor, and item templates render each row of a query.\n\n# Page templates\nA page tagged `meta/template/page` is a page template. Its body becomes the new page's text; `|^|` marks where the cursor lands. The user creates a page from it with `Page: From Template`, or with a command the template defines. Keep template pages together, conventionally under `Library/Page Templates/`.\n\nOptional frontmatter keys:\n* `suggestedName`: proposed name for the new page; may use expressions, such as `Garden/${date.today()}`.\n* `confirmName`: ask to confirm the name (default `true`).\n* `openIfExists`: open the page if it already exists instead of failing.\n* `command`: also register the template as a command with this name; `key` and `mac` bind a shortcut (they need `command`).\n* `frontmatter`: frontmatter for the new page. Write it as a literal block (`frontmatter: |`) so `${...}` inside it is evaluated; a nested mapping is copied as is.\n* `priority`: order in which template commands are created; a template with the same `command` as a built-in one overrides it.\n\n```markdown\n---\ntags: meta/template/page\ncommand: \"Garden: New Bed\"\nsuggestedName: \"Garden/Beds/\"\nfrontmatter: |\n  tags: garden-bed\n  planted: ${date.today()}\n---\n# Plants\n* |^|\n```\n\nQuote any frontmatter value containing a colon followed by a space, as `command` above: unquoted it is invalid YAML and the command never appears.\n\n# Slash templates\nA page tagged `meta/template/slash` defines a slash command named after the last part of the page name: `Library/Slash Templates/action-items` gives `/action-items`. The body is inserted at the cursor, with `${...}` evaluated at that moment and `|^|` placing the cursor. Optional frontmatter: `description` (shown in the completion menu), `priority`, and the advanced `onlyContexts` and `exceptContexts`.\n\n```markdown\n---\ntags: meta/template/slash\ndescription: Insert an action items section\n---\n# Action items\n* [ ] |^|\n```\n\nTemplate commands and slash commands are registered when scripts load. A template page holds no `space-lua`, so saving it does not reload anything: after creating or renaming one, run `system.reboot()` with `lua` (or ask the user to run `System: Reload`), then confirm with `system.listCommands()`.\n\n# Item templates for queries\nItem templates render each row of a query. The standard library provides some in the `templates` table:\n\n| Template | Renders |\n| --- | --- |\n| `templates.pageItem` | A page as `* [[name]]` |\n| `templates.fullPageItem` | A page as a link labeled with its full name |\n| `templates.taskItem` | A task as a toggleable checkbox linked to its source |\n| `templates.itemItem` | A list item linked to its source |\n| `templates.paragraphItem` | A paragraph linked to its source |\n| `templates.tagItem` | A tag as a linked hashtag |\n\nCall one in the `select` clause of a query in page Markdown; the rows render as a list:\n\n```markdown\n${query[[from t = index.tasks(\"garden\") where not t.done select templates.taskItem(t)]]}\n```\n\nTo define your own, assign `template.new` to a key of `templates` in a `space-lua` block (on a page under `Library/`, such as `Library/Config`):\n\n```lua\n--- Renders a book with its author.\n--- @param b book\ntemplates.bookLine = template.new [==[\n* [[${name}]] by ${author or \"unknown\"}\n]==]\n```\n\nInside the template, the row's attributes are plain names (`name`, `author`). A missing attribute renders as the text `nil`, so give optional ones a default with `or`, as `author` does above; indexing into a missing one (`${author.first}`) is an error. In a page expression each row renders on its own line, so start the template with `* ` for a bullet list. `template.each` and `table.concat` join results without separators, so end the template with a newline (as above and as the built-ins do). The `---` comment and `@param` (a tag, or a union like `page|aspiring-page`) document the template for completion and the query editor. Use it like the built-ins: `select templates.bookLine(b)`.\n\n# Template API\n* `template.new(text, stripIndent)` returns a function that takes a table and returns the filled-in text. Conventionally the text uses `[==[` and `]==]` delimiters. Unless `stripIndent` is `false`, a leading four-space indent is removed from each line.\n* `template.fromPage(name, raw)` reads a template page, drops its frontmatter, and returns the template function and the frontmatter. With `raw` true, the function returns the text without evaluating it.\n* `template.each(collection, fn)` applies `fn` to each element and concatenates the results (nil when there are none). It predates templates in `select`, which is now preferred.\n\n```lua\nlocal line = template.new [==[${name} is ${status}]==]\nreturn line({name = \"Orchard\", status = \"planning\"})\n```\n\nA template that embeds a widget returns a widget fragment rather than a string: it renders anywhere, but cannot be used as plain text such as a page name.\n\n# Check your work\nTest a template with `lua` first, as above. For an item template in a page, `read` the page with `rendered: true` to see the rows it produces and any lint problems. For page and slash templates, check that the command exists after the reload; creating a page from one is up to the user.\n"},{"path":"Library/Std/Editor/Mention Inbox.md","lastModified":1794685544000,"text":"Surfaces open recipient mentions in the right-hand sidebar.

The Mention Inbox shows the same queue in the sidebar.\n\n# Know whose queue it is\nConfirm the recipient name from the user's request or the space's operating manual. Do not assume the runtime account is the identity you are acting as, and do not invent a person when it is ambiguous: ask. `identity.own()` returns the runtime's own identity as `{name, id, detail}` (or nil when the space does not know); use it as a check against what you were told, not as the answer.\n\n# List the open work\n```lua\nreturn identity.mentions(\"helper\", {limit = 100, offset = 0})\n```\n\nIt queries `at-mention` and page-level `recipients` relations, filters completed tasks, and returns `{recipient, mentions, total, truncated}` sorted by page and position. When `truncated` is true, add the number of returned entries to `offset` and call again. If `identity.mentions` is missing, the runtime is too old: report that. Check `spacelua.describe(\"identity.mentions\")` for the installed signature.\n\nEach entry has `kind`, `page`, `ref`, `target`, optional `pos`, `snippet`, optional `fromTag`, `inComment`, and the available authors (`by`) and `replyTo`. Ordinary mentions reply to the first signed author, otherwise to `identity.own()`. Several authors stay in `by`, so choose from context. `pos` is a UTF-16 position, not a line, so locate the text by reading the page; the snippet and position are a snapshot that goes stale after edits. Page-level recipients currently fall back to the current identity, so look at the page's authors before choosing whom to address.\n\nA text `search` for `@name` is not equivalent: it also matches code examples, completed tasks and signatures.

For `kind` `page` (a frontmatter `recipients` entry), remove the name from `recipients` when that work is done.\n* Leave unclear or unfinished work visible. Never erase a request just to empty the queue.\n\nAfterwards `read` the saved page and query again once the index has caught up. Report which items you handled and which are still pending.

When client encryption is enabled they are stored encrypted like the rest of the local data.\n\nTwo commands manage them:\n\n* `Credentials: List`: show the stored credentials\n* `Credentials: Clear`: clear a credential (or all of them), so you are asked to sign in again the next time it is needed\n\n# For library authors\nCredential keys are `provider` or `provider:target`, e.g. `github` or `sb:https://example.com/notes`.\n\nRegister a provider:\n\n```lua\nauth.defineProvider {\n  id = \"github\",\n  -- Sign in, returns the credential (a table, e.g. {access_token = \"...\"})\n  connect = function(target) ... end,\n  -- Optional: renew an expired credential\n  refresh = function(cred) ... end,\n  -- Turn a credential into HTTP headers\n  headers = function(cred) return {Authorization = \"Bearer \" .. cred.access_token} end,\n  -- Optional: defaults to `cred.expires_at` (ms) being within a minute of now\n  expired = function(cred) ... end,\n  -- Optional: a credential from configuration (e.g. a personal token), used\n  -- when none is stored; it is never stored and nothing signs in while it is set\n  configured = function(target) ... end,\n}\n```\n\nThen call `auth.fetch(\"github\", url, options, true)`, which makes the request with the credential's headers. With `true` as the last argument it signs in when there is no credential, and when the request is rejected (401) it drops the stored credential and signs in again, once. Without it, it never signs in: it sends a stored (and if needed refreshed) credential if there is one, and repeats a rejected request without it, so public content stays readable.\n\n`auth.headers(\"github\")` and `auth.optionalHeaders(\"github\")` return just the headers, signing in when needed or never, respectively.\n\nOther functions: `auth.getCredential(key)`, `auth.setCredential(key, value)`, `auth.deleteCredential(key)`, `auth.listKeys(prefix)`, `auth.splitKey(key)` and `auth.list()`.\n\n# Implementation\n```space-lua\n-- priority: 10\nauth = {}\n\n-- All credentials, by key, under one client store key\nlocal storeKey = \"credentials\"\n\nlocal function readAll()\n  return clientStore.get(storeKey) or {}\nend\n\nfunction auth.listKeys(prefix)\n  local keys = {}\n  for key in pairs(readAll()) do\n    if not prefix or key:startsWith(prefix) then\n      table.insert(keys, key)\n    end\n  end\n  table.sort(keys)\n  return keys\nend\n\nfunction auth.getCredential(key)\n  return readAll()[key]\nend\n\n-- Returns the stored credential: value plus `provider` and `createdAt`\nfunction auth.setCredential(key, value)\n  local cred = {}\n  for k, v in pairs(value) do\n    cred[k] = v\n  end\n  cred.provider = (auth.splitKey(key))\n  cred.createdAt = os.time() * 1000\n  local all = readAll()\n  all[key] = cred\n  clientStore.set(storeKey, all)\n  return cred\nend\n\n-- Rebuilt rather than set to nil: the store would keep the key (as null)\nfunction auth.deleteCredential(key)\n  local rest = {}\n  for k, cred in pairs(readAll()) do\n    if k != key then\n      rest[k] = cred\n    end\n  end\n  clientStore.set(storeKey, rest)\nend\n\n-- \"github\" -> \"github\", nil; \"sb:https://h/notes\" -> \"sb\", \"https://h/notes\"\nfunction auth.splitKey(key)\n  local colon = key:find(\":\", 1, true)\n  if not colon then\n    return key, nil\n  end\n  return key:sub(1, colon - 1), key:sub(colon + 1)\nend\n\nlocal providers = {}\n\nfunction auth.defineProvider(p)\n  providers[p.id] = p\nend\n\nlocal function expired(p, cred)\n  if p.expired then\n    return p.expired(cred)\n  end\n  return cred.expires_at != nil and cred.expires_at < os.time() * 1000 + 60000\nend\n\n-- The provider and target of a key, and the credential to use: the stored\n-- one (renewed when expired), else the provider's configured one; nil when\n-- there is neither\nlocal function usableCredential(key)\n  local id, target = auth.splitKey(key)\n  local p = providers[id]\n  if not p then\n    error(\"No auth provider: \" .. id)\n  end\n  local cred = auth.getCredential(key)\n  if cred and expired(p, cred) then\n    local ok, refreshed = false, nil\n    if p.refresh then\n      ok, refreshed = pcall(p.refresh, cred)\n    end\n    -- Only stored once refreshing succeeded\n    if ok and refreshed then\n      cred = auth.setCredential(key, refreshed)\n    else\n      cred = nil\n    end\n  end\n  if not cred and p.configured then\n    cred = p.configured(target)\n  end\n  return p, target, cred\nend\n\nfunction auth.headers(key)\n  local p, target, cred = usableCredential(key)\n  if not cred then\n    -- Only stored once connecting succeeded\n    cred = auth.setCredential(key, p.connect(target))\n  end\n  return p.headers(cred)\nend\n\n-- Like auth.headers, but never signs in: nil without a usable credential\nfunction auth.optionalHeaders(key)\n  local p, _, cred = usableCredential(key)\n  if not cred then\n    return nil\n  end\n  return p.headers(cred)\nend\n\n-- net.proxyFetch with the credential of key.

This happens automatically the first time you share or access something that needs it: a device code is shown, which you enter on github.com to authorize SilverBullet. The resulting token is stored on this device only (see `Credentials: List`) and can be cleared with `Credentials: Clear`.\n\nOptionally, you can use a [personal Github token](https://github.com/settings/personal-access-tokens) (with repo and gists permissions) instead. Configure your token somewhere in Space Lua (use a `space-lua` block), ideally a `SECRETS` page. When set (and you have not connected through the device flow), it is used without asking you to sign in.\n\n```lua\nconfig.set(\"github.token\", \"your token\")\n```\n\nTo use your own Github OAuth app for the sign-in instead of the default one, set its client ID:\n\n```lua\nconfig.set(\"github.clientId\", \"your client id\")\n```\n\nIn addition, to push to Github repos you need to configure a name and email that will be part of the commit:\n\n```lua\nconfig.set(\"github.name\", \"John Doe\")\nconfig.set(\"github.email\", \"john@doe.com\")\n```\n\n# Implementation\n\n##

infrastructure of Page Templates.\n---\nPage templates can be used to automate or simplify the creation of pages based on a template.\n\n# Creating a page template\nTo create a page template, create a page and tag it with `#meta/template/page`.\n\nThe last component of the page name will be used as the template name.\n\n## Cursor placement\nIn the template’s body text, you can optionally use `|^|` as a placeholder for where the cursor should be after creating\nthe page.\n\n## Configuration\nOptional keys you can set in the page’s frontmatter:\n\n* `suggestedName`: the proposed name for the new page, can use embedded Lua expressions, like `Daily/${date.today()}`.\n* `confirmName`: Confirm the suggested page name before creating it (defaults to `true`). Only effects pages created by a key binding, otherwise you will always be prompted to confirm the new page name.\n* `openIfExists`: If a page with the `suggestedName` already exists, open it rather than showing an error.\n* `command`: expose the page template as a command with this name.\n* `key`: Bind the snippet to a keyboard shortcut (note: this requires to _also_ specify the `command` configuration).\n* `mac`: Bind the snippet to a Mac-specific keyboard shortcut.\n* `frontmatter`: Frontmatter to set in the resulting page. Use a YAML literal block scalar\n  (`frontmatter: |`) so that the value is passed as a string and `${...}` Lua interpolation\n  works. A nested YAML mapping is also accepted (and serialized verbatim), but interpolation\n  will be skipped in that case.\n* `priority`: Similar to how space lua scripts are loaded, this controls the order in which page template _commands_ are\n  created (see \"overriding page templates\" below)\n\n## Example: Daily note\nThe following creates a page template that can be run using the `Journal: Daily Note` command, it automatically creates\n`Daily/today’s date` if it does not already exist with a bulleted list, putting the cursor at the first bullet. If the\npage already exists, it navigates there.\n\n~~~\n---\ncommand: \"Journal: Daily Note\"\nsuggestedName: \"Daily/${date.today()}\"\nconfirmName: false\nopenIfExists: true\ntags: meta/template/page\n---\n* |^|\n~~~\n\n# Currently active page templates\n${query[[\n  from p = index.pages(\"meta/template/page\")\n  select templates.fullPageItem(p)\n]]}\n\n# Instantiating page templates\n\nYou can create a page based on a page template via the ${widgets.commandButton(\"Page: From Template\")} command, or via\nthe command name that you defined in your template’s frontmatter.\n\n# Overriding page templates\n\nIf you would like to override an existing page template (for instance the Quick Note) template with your own, you can\ntake advantage of the load order determined by the `priority` frontmatter. Built in page templates will have a priority\nset that is higher than the default. Therefore, their commands and keybindings will be set early. Therefore, by simply\ndefining your own version of the page template _with the same command name_ will let that version override the versions\nthat are built in.\n\n## Example: overriding the Quick Note template\n\n~~~\n---\ncommand: Quick Note\nkey: \"Ctrl-q q\"\nsuggestedName: \"Quick notes/${os.date('%Y-%m-%d/%H-%M-%S')}\"\nconfirmName: false\ntags: meta/template/page\n---\nThis is my quick note version\n~~~\n\n# Implementation\n```space-lua\n-- priority: 10\n\ntag.define {\n  name = \"meta/template/page\",\n  schema = {\n    type = \"object\",\n    properties = {\n      tags = {\n        anyOf = {\n          { type = \"array\", items = schema.string() },\n          schema.string(),\n        },\n      },\n      frontmatter = {\n        anyOf = { schema.string(), schema.object() },\n      },\n      suggestedName = schema.string(),\n      confirmName = schema.boolean(),\n      openIfExists = schema.boolean(),\n      command = schema.string(),\n      key = {\n        anyOf = {\n          { type = \"array\", items = schema.string() },\n          schema.string(),\n        },\n      },\n      mac = {\n        anyOf = {\n          { type = \"array\", items = schema.string() },\n          schema.string(),\n        },\n      },\n      priority = schema.number(),\n      description = schema.string(),\n    },\n  }\n}\n\nfunction template.createPageFromTemplate(templatePage, pageName, openIfExists)\n  -- Won't override an existing page\n  if space.pageExists(pageName) then\n    if openIfExists then\n      editor.navigate(pageName)\n      return\n    else\n      editor.flashNotification(\"Page \" .. pageName .. \" already exists\", \"error\")\n      return\n    end\n  end\n  if system.getMode() ~= \"rw\" then\n    editor.flashNotification(\"Cannot instantiate template '\" .. templatePage .. \"', you do not have write permission.\", \"error\")\n    return\n  end\n  local tpl, fm = template.fromPage(templatePage)\n  local initialText = \"\"\n  if fm.frontmatter then\n    local frontmatterText\n    if type(fm.frontmatter) == \"string\" then\n      -- String form: supports `${...}` Lua interpolation\n      frontmatterText = template.new(fm.frontmatter)()\n    else\n      -- Table form (e.g. nested YAML mapping): encode as YAML\n      frontmatterText = yaml.stringify(fm.frontmatter)\n    end\n    initialText = \"---\\n\"\n      .. string.trim(frontmatterText)\n      .. \"\\n---\\n\"\n  end\n  space.writePage(pageName, initialText)\n  editor.navigate(pageName)\n  -- Insert there, supporting |^| cursor placeholder\n  editor.insertAtPos(tpl(), #initialText, true)\nend\n\n-- Create commands for all page templates with a command key in frontmatter,\n-- again on index:ready: on a fresh client the index is still empty at load\nlocal function definePageTemplateCommands()\n  for pt in query[[\n      from tp = index.pages(\"meta/template/page\")\n      where tp.command\n      order by tp.priority desc\n    ]] do\n    command.define {\n      name = pt.command,\n      key = pt.key,\n      mac = pt.mac,\n      requireMode = \"rw\",\n      run = function()\n        local pageName\n        if pt.suggestedName then\n          pageName = (template.new(pt.suggestedName))()\n        end\n        if pt.confirmName != false then\n          pageName = string.trim(some(editor.prompt(\"Page name\", pageName)) or \"\")\n        end\n        if pageName == \"\" then\n          editor.flashNotification(\"No page name given for '\" .. pt.command .. \"', unable to continue.\", \"error\")\n          return\n        end\n        template.createPageFromTemplate(pt.name, pageName, pt.openIfExists)\n      end\n    }\n  end\nend\n\ndefinePageTemplateCommands()\nevent.listen {\n  name = \"index:ready\",\n  run = definePageTemplateCommands\n}\n\nlocal function cleanName(path)\n  local parts = path:split(\"/\")\n  return parts[#parts]\nend\n\n-- The second half of picking a template: name the page it makes, then make\n-- it.

This page covers choosing a mechanism and the conventions the API listings do not. For every option of `widget.new` (columns and their types, `filter`, `segments`, `dropdown`, `actions`, `refreshOn`), read the `API/widget` page, section \"Lists, trees and tables\", of the SilverBullet documentation (docs.silverbullet.md; edge.silverbullet.md for Edge builds). Check other functions with `spacelua.describe` (see the Space Lua page).\n\n# Pick the mechanism\n* Plain Markdown and `${query[[...]]}` expressions first. A query result renders as a table and updates by itself when the pages it reads change, with links and hover previews intact. For a simple table of pages or tasks, this is the whole answer: `${query[[from p = index.pages(\"book\") where p.status == \"unread\" select {Book = markdown.link(p), Author = p.author}]]}`.\n* A live widget, `widget.new { source = ..., presentation = { mode = \"table\" } }`, only when the table needs more: a filter box, selection, actions, or columns of `ref` type. What its source reads is tracked, so `refreshOn` is only for things SilverBullet does not track, such as your own events.\n* Custom HTML: `widget.htmlBlock(dom.div { ... })` or `widget.html(...)`. Isolated JavaScript: `widget.sandbox`.\n* Fenced data blocks: a fence whose language is a hash-tag name (for example a fence opened with `#contact`) holds YAML. Each document becomes a queryable object with that tag.\n* Code widgets: `codeWidget.define { language = \"#contact\", render = function(body, pageName) ... end }` draws every fenced block of that language. `render` returns Markdown or a widget.\n* Views: `view.define` for panels and docks outside the page body.\n\nChips, stat cards and bar charts are not in core; they come from the optional Dashboard library. Do not assume `widgets.chip`, `widgets.stat`, `widgets.bars` or `widgets.grid` exist until `spacelua.describe` finds them.\n\n# Lists and tables\n```lua\nboard = board or {}\n\nfunction board.tasks()\n  return widget.new {\n    title = \"Tasks\",\n    refreshOn = { \"board:filter\" },  -- our own event; what the source reads is tracked\n    source = function()\n      return query[[\n        from t = index.tasks()\n        where not board.onlyBlocked or t.state == \"blocked\"\n        order by t.page, t.pos\n        select { text = t.name, state = t.state, ref = t.ref }\n      ]]\n    end,\n    presentation = { mode = \"table\", columns = {\n      { attribute = \"text\", label = \"Task\", type = \"text\" },\n      { attribute = \"ref\", label = \"Where\", type = \"ref\" },\n    } },\n    filter = { inline = true },  -- a filter box in the title\n  }\nend\n\nfunction board.toggle()\n  board.onlyBlocked = not board.onlyBlocked\n  event.dispatch(\"board:filter\")\nend\n```\n\nPlace the widget by calling `board.tasks()` in a page expression, with `widgets.button(\"Only blocked\", board.toggle)` beside it. Segments and dropdowns exist only in panels; inline, use a button plus an event listed in `refreshOn`. Sort in the source: table headers do not sort. A widget with `source` cannot also set `markdown` or `html`.\n\nA plain expression runs once when the page opens and re-runs only when something it read changes. Time, `datastore`, `config`, network calls and Lua globals are not tracked, so render those through `widget.new { content = ..., refreshOn = {...} }`.\n\n# Tones and color\nTones are `success`, `warning`, `danger`, `info`, `neutral` and `accent`, with CSS variables `--tone-<name>` and `--tone-<name>-soft` that every theme sets to read well on its background. In your own CSS color with `var(--tone-danger)` rather than fixed values. If you must use a fixed color, check it in a light and a dark theme.\n\n# DOM builder\n* `dom.tag { attr = \"value\", child, child }`: string keys are attributes, and `on*` keys are event handlers. `class` also takes a list (`{ \"card\", urgent and \"card-urgent\" }`), and `style` takes a table (`{ width = \"40%\" }`).\n* String children render as Markdown, and whitespace between sibling children is dropped: write `\"**12** checks\"` as one string. `dom.text(s)` adds literal text; use it for names, titles and anything you did not write.\n* A list of children is added in order and `false` children are skipped: build rows in a loop, then `dom.ul { rows }`.\n* A link that looks and navigates like a SilverBullet link: `dom.a { class = \"wiki-link\", [\"data-ref\"] = page, dom.text(name) }`.\n* To navigate otherwise, use a button or an `onclick` handler that calls `editor.navigate(page)`, or put a `[[Page]]` wiki link in a string child.\n\n# Data in pages\n* Keep records as pages with frontmatter or tag-language data blocks, so each stays readable as Markdown.\n* Avoid tag names SilverBullet uses for its own objects: `page`, `task`, `item`, `paragraph`, `header`, `link`, `tag`, `data`, `anchor`, `table`.\n* Quote YAML values that contain a colon followed by a space or a `#`, or that start with `[` or `{`.\n* Each `space-lua` block is its own chunk. Start blocks that share a namespace with `ns = ns or {}`, and put `-- priority: N` on the defining block.\n\n# Styling\nPut `space-lua` and `space-style` blocks on a page under `Library/`; they do not run on other pages. Put CSS in a `space-style` block and style classes you attach:\n\n* Tag-driven classes: `tag.define { name = \"book\", pageDecoration = { cssClasses = { \"book-page\" } } }` puts `book-page` on the page body and on links to those pages.\n* Widget classes: give widget roots your own class and scope rules under it.\n* Editor rules need SilverBullet's specificity: `body.book-page #sb-main .cm-editor { ... }`.\n\nFor themes, theme variables, light and dark, and how to inspect an element before styling it, load the Styling skill.\n\n# Safety\nBuild markup with `dom.*` and `dom.text`, not by concatenating HTML strings. If you must, escape text with `string.escapeHtml(s)`. To show Markdown written by a user, imported or generated, use `widget.markdown(text, { evaluate = false })`: expressions, code widgets and transclusions then stay literal. Never evaluate page content you are only displaying.\n\n# Check what you built\nCheck your work: read the result of the `write`/`edit` (it reports script load errors), then `read` the page with `rendered: true` (evaluated output plus lint problems), then take a `screenshot` when the look matters.\n\n`space.lint()` without a page checks every page, so run it before calling work done. A widget that throws does not always show up as a lint problem, so for widgets the rendered read and the screenshot are what count. `system.recentLogs(50)` holds \"Lua widget error on ...\" lines; ignore lines logged before the latest \"Loaded N scripts\", which are often transient. Scripts and styles reload after each `write` or `edit` of a page that holds them; after changing files any other way, including `space.writePage` from `lua`, call `system.reboot()` first. After a reboot, navigate to the page again (`editor.navigate(page)`, then `editor.awaitRender()`) so widgets re-render before you read or screenshot it. Check the look in a light and a dark theme by switching with `theme.setDeviceTheme(...)`, and restore the device theme you recorded before switching: on SilverBullet Desktop it is the user's own. The Styling skill has the steps.\n\nTo add to an existing namespace in a large library page, `read` it with `outline: true` (headings, code blocks and functions with line numbers), then read just the part you need with `offset`/`limit`, rather than reading the whole page.\n"},{"path":"Library/Std/Widgets/Embed.md","lastModified":1794685544000,"text":"Implements useful embed widgets.\n\n# Youtube\n## Example\n${embed.youtube \"https://youtu.be/t1oy_41bDAY?si=X76FvJEUlJnApwEg\"}\n\n# Peertube\n## Example \n${embed.peertube \"https://peertube.fr/w/kkGMgK9ZtnKfYAgnEtQxbv\"}\n\n# Vimeo\n## Example\n${embed.vimeo \"https://vimeo.com/1084537\"}\n\n# Implementation\n```space-lua\n-- priority: 10\nlocal embedVideoSpecSchema = {\n  type = \"object\",\n  properties = {\n    url = { type = \"string\"},\n    width = { type = \"number\"},\n    height = { type = \"number\"},\n  },\n  required = {\"url\"}\n}\n\nfunction embed.youtube(specOrUrl)\n  if type(specOrUrl) == \"string\" then\n    specOrUrl = { url = specOrUrl }\n  end\n  local validationResult = jsonschema.validateObject(embedVideoSpecSchema, specOrUrl)\n  if validationResult then\n    error(validationResult)\n  end\n  local videoId = string.match(specOrUrl.url, \"youtube%.com/watch%?v=(.+)\")\n  if not videoId then\n    videoId = string.match(specOrUrl.url, \"youtu%.be/(.+)\")\n  end\n  if not videoId then\n    videoId = string.match(specOrUrl.url, \"youtube%.com/shorts/(.+)\")\n  end\n\n  if not videoId then\n    error(\"No video id found\")\n  end\n  \n  local width = specOrUrl.width or \"100%\"\n  local height = specOrUrl.height or \"400px\"\n  return widget.html(dom.iframe {\n    src=\"https://www.youtube.com/embed/\" .. videoId,\n    style=\"width: \" .. width .. \"; height: \" .. height,\n    class = \"sb-video-embed\",\n    referrerpolicy = \"strict-origin-when-cross-origin\",\n    allow = \"accelerometer; autoplay; clipboard-write; encrypted-media; fullscreen; gyroscope; picture-in-picture; web-share\",\n    allowfullscreen = \"true\",\n  })\nend\n\nfunction embed.peertube(specOrUrl)\n  if type(specOrUrl) == \"string\" then\n    specOrUrl = { url = specOrUrl }\n  end\n  local validationResult = jsonschema.validateObject(embedVideoSpecSchema, specOrUrl)\n  if validationResult then\n    error(validationResult)\n  end\n  \n  local tempHost = string.match(specOrUrl.url, \"https://(.+)\")\n  local lastIndex = string.find(tempHost, \"/w/\")\n  local peertubeInstance = string.sub(tempHost, 1, (lastIndex -1) )\n  local videoId = string.match(specOrUrl.url, \"/w/(.+)\")\n\n  if not videoId then\n    error(\"No video id found\")\n  end\n  \n  local width = specOrUrl.width or \"100%\"\n  local height = specOrUrl.height or \"400px\"\n  return widget.html(dom.iframe {\n    src = \"https://\" .. peertubeInstance .. \"/videos/embed/\" .. videoId,\n    style = \"width: \" .. width .. \"; height: \" .. height,\n    frameborder = \"0\",\n    allowfullscreen = \"\",\n    sandbox = \"allow-same-origin allow-scripts allow-popups allow-forms\",\n    class = \"sb-video-embed\"\n  })\nend\n\nfunction embed.vimeo(specOrUrl)\n  if type(specOrUrl) == \"string\" then\n    specOrUrl = { url = specOrUrl }\n  end\n  local validationResult = jsonschema.validateObject(embedVideoSpecSchema, specOrUrl)\n  if validationResult then\n    error(validationResult)\n  end\n  local videoId = string.match(specOrUrl.url, \"vimeo%.com/(.+)\")\n\n  if not videoId then\n    error(\"No video id found\")\n  end\n  \n  local width = specOrUrl.width or \"100%\"\n  local height = specOrUrl.height or \"400px\"\n  return widget.html(dom.iframe {\n    src = \"https://player.vimeo.com/video/\" .. videoId,\n    style = \"width: \" .. width .. \"; height: \" .. height,\n    frameborder = \"0\", \n    referrerpolicy = \"strict-origin-when-cross-origin\", \n    allow = \"fullscreen; picture-in-picture; clipboard-write; encrypted-media; web-share\",   \n    allowfullscreen = \"\",\n    class = \"sb-video-embed\"\n  })\nend\n```\n\n## Styling\n\n```space-style\n.sb-video-embed {\n  border: 0 !important;\n}\n```\n\n# General implementation\n```space-lua\n-- priority: 50\nembed = {}\n```\n"},{"path":"Library/Std/Widgets/Inputs.md","lastModified":1794685544000,"text":"---\ndescription: Reusable input widgets (text, number, lists, chips with completion) for widgets and forms.\ntags: meta/api\n---\nInput widgets for building your own forms and widgets, all in the `widgets` namespace and named `widgets.*Input`. Each function takes one options table and returns a DOM node, which you can put in `dom.*` trees and `widget.htmlBlock`. The widgets know nothing about pages or frontmatter: they show `value` and call `onChange` with the new value. The [[Library/Std/Widgets/Object Form|object form]] (frontmatter and data blocks) is built from them.\n\nOptions every input takes:\n\n| option | meaning |\n|---|---|\n| `value` | the current value |\n| `onChange(value)` | called with the new value when the user commits a change; `nil` means empty |\n| `readOnly` | shows the value as plain text, with nothing to edit |\n| `placeholder` | hint shown while empty (text-like inputs) |\n\n# Example\nA tag picker and a note field that flash what was picked:\n\n```lua\nlocal picked = {}\n\nwidget.htmlBlock(dom.div {\n  widgets.tagsInput {\n    value = picked,\n    onChange = function(list)\n      picked = list or {}\n    end,\n  },\n  widgets.textInput {\n    placeholder = \"Note\",\n    onChange = function(text)\n      editor.flashNotification(\"Note: \" .. text)\n    end,\n  },\n  dom.button { \n    onclick = function()\n      editor.flashNotification(\"Tags: \" .. table.concat(picked, \", \"))\n    end,\n    dom.text(\"Show tags\")\n  },\n})\n```\n\n# API\n\n## widgets.textInput(opts)\nA text field that wraps long values and grows to fit them. Enter commits, Shift-Enter inserts a newline. `onChange` receives the text.\n\n`[[links]]` in the text show as links (click or tap to follow) while it isn't being edited; a click elsewhere in it edits the text. Typing `[[` completes pages and anchored objects: ArrowUp/ArrowDown, Enter or Tab inserts `[[Page]]` (or `[[$name]]`, closing the `]]` when needed), Esc closes the list. `links = false` turns both off. Read-only text shows its links too.\n\n## widgets.numberInput(opts)\nA number field. `onChange` receives a number, or `nil` when cleared. Text that isn't a number is ignored.\n\n## widgets.booleanInput(opts)\nA checkbox. `onChange` receives `true` or `false`.\n\n## widgets.dateInput(opts)\nA date field for a `YYYY-MM-DD` `value`, always shown as `YYYY-MM-DD` (never in the browser's locale format), with a calendar button that opens the browser's date picker. `onChange` receives the date as a `YYYY-MM-DD` string, or `nil` when the field is cleared. Typed text that isn't a real `YYYY-MM-DD` date is marked invalid (the reason shows as the field's tooltip) and not passed on.\n\n## widgets.selectInput(opts)\nA dropdown over `opts.options`, a list of values. `onChange` receives the picked value, or `nil` for the empty choice.\n\n## widgets.listInput(opts)\nA list of strings, one text field per item. Items show and complete `[[links]]` like `widgets.textInput` (`links = false` turns that off). Each item has a `widgets.menu` (Move up, Move down, Insert below, Remove), and \"+ add item\" appends one. Keys: Enter inserts an item below, Shift-Enter inserts a newline in the item, Backspace in an empty item removes it, Alt+ArrowUp and Alt+ArrowDown move the item. `onChange` receives the new list, or `nil` when it's empty.\n\n## widgets.menu(opts)\nA \"...\" context button that opens a context menu. `opts.items` is a list, or a function returning one when the menu opens, of:\n* `{ label = …, onSelect = function() … end }`, plus optionally `disabled = true` with a `reason` (shown muted, the reason as tooltip; picking it flashes the reason) and `danger = true` (for Delete and the like);\n* `{ header = \"…\" }`: a muted line that can't be picked;\n* `{ separator = true }`.\n\n`opts.title` is the button's tooltip; with `opts.keepFocus`, clicking the button leaves focus where it was (in a field being edited). The button shows when the mouse rests on the nearest element with class `sb-in-menu-owner` (after a moment, fading again once the mouse is still, like every ⋯ menu), when that element has focus, and always on touch screens. Keys: Enter or Space on the button opens it with focus on the first item; ArrowUp/ArrowDown move, Enter picks, Esc closes (and returns focus to the button when focus was in the menu). A click outside closes it. `widgets.openMenu(node)` opens a menu node the same way, e.g. for a keyboard shortcut.\n\n```lua\ndom.div {\n  class = \"sb-in-menu-owner\",\n  dom.text(\"Report\"),\n  widgets.menu {\n    items = {\n      { label = \"Rename\", onSelect = function() editor.flashNotification(\"Rename\") end },\n      { separator = true },\n      { label = \"Delete\", danger = true, disabled = true, reason = \"Reports are kept\" },\n    },\n  },\n}\n```\n\n## widgets.chipsInput(opts)\nA list shown as chips, with a text field that completes. `onChange` receives the new list, or `nil` when it's empty. Extra options:\n\n| option | meaning |\n|---|---|\n| `complete(prefix)` | returns options `{ value, label?, description? }`. Called on first focus (to warm a cache) and while typing; the input filters and ranks the result itself, so it may return everything |\n| `allowNew` | Enter, space or comma turn typed text into a chip even without a matching option (default `true`) |\n| `sigil` | shown before each chip and option label, such as `\"#\"` |\n| `display(value)` | the text of a chip (default: the value) |\n| `identify(value)` | what makes two values the same, to skip duplicates (default: the value) |\n| `clean(text)` | turns typed text into a value, or `nil` to drop it (default: trimmed text) |\n| `onOpen(value)` | called when a chip is clicked |\n| `chipClass` | extra CSS class for chips |\n| `max` | most chips; when full, a new pick replaces the last one |\n\nKeys: ArrowUp and ArrowDown move through the options, Enter or Tab accept one, Escape closes the list, Backspace in the empty field removes the last chip.\n\n## widgets.tagsInput(opts)\nChips for tag names, completing from the tags in the space. Values are tag names without `#`; clicking one opens its tag page.\n\n## widgets.identitiesInput(opts)\nChips for `@names`, completing from known identities. Values are names without `@`; clicking one opens the Mention Inbox for that name.\n\n## widgets.refInput(opts) and widgets.refListInput(opts)\nOne or a list of references (`\"[[Page]]\"`, `\"[[$anchor]]\"`), as chips completing from pages and anchored objects. `opts.tag` limits them to that tag. Clicking a chip navigates to its target.\n\n## widgets.schemaInput(schema, opts)\nPicks the input for a JSON Schema property and passes `opts` on (with `opts.schema` set): a registered format first, then `enum`, `ref` (`schema.ref()`), lists of refs, tags (`schema.tags()`), identities (`schema.identities()`), lists of strings, `date`, and the plain types. The schema's `description` becomes the input's tooltip.\n\n## widgets.inputFormats\nInputs for custom string formats, by format name. `widgets.schemaInput` (and so the object form) uses one for any property with that `format`:\n\n```lua\nwidgets.inputFormats.rating = function(opts)\n  return dom.input {\n    type = \"range\", min = \"0\", max = \"5\",\n    value = tostring(opts.value or 0),\n    disabled = opts.readOnly and \"disabled\" or nil,\n    onchange = function(e) opts.onChange(tonumber(e.target.value)) end,\n  }\nend\n```\n\n# Implementation\n\nThe implementation is split across these pages:\n\n${widgets.subPages()}\n\n# Styles\nThe inputs' styles (the `sb-in-*` classes) ship with SilverBullet itself, so forms look right before a space is indexed.

Each attribute gets an input chosen from its schema: the schema of the first of the object's tags that declares it, then the schema of its root tag (`page` for frontmatter, `data` for a data block).\n\nThe form knows nothing about pages or where the YAML is: it reads the render context and writes through `ctx.set`, `ctx.remove` and `ctx.move`.\n\n# Field kinds\nEvery row has a kind that picks its input:\n\n| kind | used for | input |\n|---|---|---|\n| `string` | text, and any string without a better match | wrapping text field; Shift+Enter for a new line |\n| `number` | numbers | number field |\n| `boolean` | `true` or `false` | checkbox |\n| `date` | `schema.date()`, or a `YYYY-MM-DD` value, quoted or not (`2026-12-01`, `\"2026-12-01\"`); a date-time is a `string` | `YYYY-MM-DD` text field with a calendar button; written as a quoted string |\n| `enum` | `schema.enum { ... }` | dropdown |\n| `ref` | `schema.ref(\"person\")`, or a value that is exactly one wikilink | chip with completion |\n| `refs` | `schema.array(schema.ref(\"person\"))`, or a list of wikilinks | chips with completion |\n| `tags` | `schema.tags()`, such as `tags` | `#tag` chips completing from the space's tags |\n| `identities` | `schema.identities()`, such as `recipients` and `authors` | `@name` chips completing from known identities |\n| `strings` | a list of strings, or \"list or string\" schemas like `aliases` | one line per item |\n| `unknown` | nested objects and other values the form can't edit | \"(edit in source)\" |\n\nA schema with a custom `format` uses `widgets.inputFormats[format]` when one is registered (see [[Library/Std/Widgets/Inputs]]). It gets the input options plus `key`, `label`, `page`, `raw` (the value as written in the YAML) and `yamlType`.\n\nWhen a present value doesn't match its schema (a plain `Bob` in a `ref` field, say), the row uses the input inferred from the value and shows the validation message as a warning. The value is never coerced. An attribute with no value and no schema (`due:`) is edited as a `string`.\n\n# The form\nRows come in this order: `tags`, the other attributes in YAML order, the absent properties of the object's own tags (faint, sorted by key), then \"+ add attribute\". Edits are written as ordinary editor changes when committed (Enter, blur, a pick, a chip added or removed), so undo works as with typing.\n\n* Each attribute in the YAML has a ⋯ menu (shown on hover or focus, always on touch screens; Shift+F10 or the context menu key opens it from the row's field): its type as a header line, **Move up** and **Move down** (reorders the keys in the YAML), **Change type…** for attributes without a schema, and **Delete**. Change type… converts the value in the YAML to another type.\n* A value that doesn't fit its schema shows a warning with the validation message.\n* Computed attributes (`created`, `lastModified` and so on for pages; `ref`, `tag`, `page` and so on for data) present in the YAML are shown read-only with a lock.\n* \"+ add attribute\" offers the absent properties of the object's tags, the editable properties of its root tag (`page` or `data`), or a new name: type it and pick it (it's offered as the second option, marked \"Add\"), or press Shift-Enter; the form then asks for its type. The new row is written on its first value; left empty, it goes away.\n* On an editable page without frontmatter, **Add tag** in the menu of the first line's ⋮ handle (hover the first line and click the handle to its left) inserts `tags:` frontmatter, and the form opens on its (empty) `tags` row. A present `tags:` key always has its row, even when empty; removing the last tag leaves `tags:` (the same holds for any property with a `schema.tags()` schema).\n* A page's `name` is its file name, so it isn't a row; in a data block, `name` is an ordinary attribute.\n* Lists keep the shape they have in the YAML: a list stays a list, and a string stays a string with its separator (`tags: a b` or `tags: a, b`). A new `tags`, `recipients` or `authors` value is written as a space-separated string; a new list of strings as a YAML list.\n* Undo and redo (Mod-z, Mod-Shift-z, Mod-y) work with focus in the form: each change is one undo step of the page; a text field with typing of its own undoes that first.\n* On a read-only page, values show as plain text, and properties the schema declares but the YAML doesn't have are left out. Attributes in the YAML always show, even with an empty value (`due:`).\n\nTo render a tag's pages or data blocks differently, give the tag its own `renderFrontmatter` or `renderDataBlock`; it can still include the default form:\n\n```lua\ntag.define {\n  name = \"project\",\n  renderFrontmatter = function(pageMeta, ctx)\n    return dom.div {\n      dom.h3 { \"Project\" },\n      objectForm.render(pageMeta, ctx)\n    }\n  end,\n}\n```\n\nTo turn the form off, use the `liveEdit.frontmatter` and `liveEdit.dataBlocks` settings (\"Edit frontmatter as a form\" and \"Edit data blocks as a form\" in the Workbench Configuration tab). They only turn off this default form; a tag's own renderer still applies.\n\n# API\n\n## objectForm.render(object, ctx)\nReturns the form as a widget. This is the `page` tag's `renderFrontmatter` and the `data` tag's `renderDataBlock`. Without `ctx`, it shows the object's values read-only.\n\n## objectForm.pickRef(tagName, label)\nOpens a picker over the pages carrying `#tagName` and the anchored objects carrying it (all pages and anchors without a tag). Returns the picked link (`\"[[Page]]\"` or `\"[[$name]]\"`), or `nil`.\n\n## objectForm.infer(value, yamlType)\nReturns a schema for a value without one. `yamlType` is the value's YAML type (`\"string\"`, `\"number\"`, `\"boolean\"`, `\"date\"`, `\"null\"`, `\"array\"` or `\"object\"`).\n\n## objectForm.fieldKind(schema)\nReturns the field kind of a property schema (see above); the kind of input `widgets.schemaInput` picks.\n\n## objectForm.typeName(kind)\nReturns the type name shown in the type menu: `string`, `number`, `boolean`, `date`, `ref`, `string[]`, `ref[]`, `tag[]` or `identity[]`. Other kinds are returned as is.\n\n## objectForm.convert(value, typeName)\nConverts a value to the given type name. Returns the new value, or `nil` and a reason when the conversion can't work (`\"abc\"` to `number`). A `date` is returned as its `YYYY-MM-DD` string.\n\n## objectForm.resolveField(key, object, ctx, tags)\nReturns `{ schema, kind, fromSchema, declared, warning }` for one attribute. `declared` is the property's schema as the tag declares it (before unwrapping `schema.nullable`), or `nil`. `tags` defaults to `objectForm.ownTags(object, ctx.kind)`.\n\n## objectForm.ownTags(object, kind)\nReturns the tags whose schemas apply before the root tag `kind`: a data object's own root tag (`contact` for ` ```#contact `), then its `tags`.\n\n## objectForm.rows(object, ctx)\nReturns the form's rows in display order: `tags`, the other present keys in YAML order, then the absent properties of the object's own tags, sorted by key (none when `ctx.readOnly` is true). Each row has `key`, `value`, `raw`, `yamlType`, `schema`, `kind`, `fromSchema`, and optionally `declared`, `warning` and `locked` (a computed, read-only attribute present in the YAML).\n\n## Internal helpers\n`objectForm.typeOptions`, `customNameProblem`, `attributeSuggestions`, `pickedAttribute`, `listItems`, `listValue`, `rowMenuItems` and `write` are exposed only so they can be tested. They are internal and may change without notice; don't build on them.\n\n# Implementation\n\n```space-lua\n-- priority: 30\nobjectForm = objectForm or {}\n\nlocal isWikilink = widgets.inputCompletion.isWikilink\nlocal unwrap = widgets.inputSchema.unwrap\n\nlocal function isList(v, yamlType)\n  if type(v) ~= \"table\" then return false end\n  if yamlType then return yamlType == \"array\" end\n  return v[1] ~= nil or next(v) == nil\nend\n\nlocal function isIsoDate(value)\n  return type(value) == \"string\" and widgets.inputDate.isoDateProblem(value) == nil\nend\n\nfunction objectForm.infer(value, yamlType)\n  -- An empty value (`due:`) is most likely waiting for text\n  if value == nil or yamlType == \"null\" then return schema.string() end\n  local t = type(value)\n  if t == \"number\" then return schema.number() end\n  if t == \"boolean\" then return schema.boolean() end\n  if t == \"string\" then\n    -- Quoted or bare, an ISO date is a date;

Opens in the right sidebar. A page with fewer than `minHeaders` headers has no outline worth showing, and the view renders nothing at all in a page dock there.\n* **Linked Mentions** (`std.linkedMentions`, command `Navigate: Linked Mentions`): every other page linking to this one, with a snippet of context.

Docks at the top of the page, open until you close it.\n\nNone of the three has an `enabled` config key any more. Each remembers its own dock and open/closed state: close it with its ×, bring it back with its command, move it with its dock menu, and that choice is what applies from then on.

If you’d rather not depend on the CDN (e.g. for offline use or a fully self-hosted space), run the `Mermaid: Download bundle for offline use` command: it downloads the esm.sh bundle plus a tiny `process` shim into your space and, once present, the renderer uses that local copy automatically instead of the CDN.\n\n# Installation\nThis is a SilverBullet library (hence the `meta/library` tag). It’s a single page — there is no release or asset to fetch. Install it through SilverBullet’s built-in **Library Manager**:\n\n1. Run the **`Library: Install`** command (or open the **Libraries** manager via the app menu / **`Libraries: Manager`** command and click **Install**).\n2. When prompted for a library URI, paste: `github:silverbulletmd/silverbullet-diagram/Mermaid.md`\n\nIf you need offline / CDN-free rendering, run the `Mermaid: Download bundle for offline use` command: it downloads the esm.sh bundle into your space, after which it’s used automatically.\n\n# Features\n## Static diagrams\nWrite a fenced `mermaid` block and move your cursor out of it to live-preview:\n\n    ```mermaid\n    flowchart TD\n        Start --> Stop\n    ```\n\n## Dynamic diagrams (Space Lua API)\nBesides static ` ```mermaid ` blocks, this library exposes a [Space Lua](https://silverbullet.md) API for generating diagrams **at runtime from your space’s data** — they re-render when the data changes, exactly like query tables and lists.\n\n# Quick start\nA raw Mermaid string:\n\n${mermaid.diagram(\"flowchart LR\\n  A[\\\"Hello\\\"] --> B[\\\"World\\\"]\")}\n\nA relation graph built live from frontmatter:\n\n${mermaid.diagram(mermaid.relationGraph{\n  pages = query[[from index.pages(\"adr\")]],\n  relations = {\"dependsOn\", \"related\", \"supersededBy\"},\n})}\n\n# API\n## Core\n### mermaid.diagram(input, opts)\nRenders a mermaid widget. `input` is a raw Mermaid string *or* a diagram **IR** table (see below). The widget has a Copy button (copies the generated source) and clickable nodes (each `click` element navigates to the named page). `opts` *(optional)* may contain `width`, `height`, `maxWidth` — CSS lengths (e.g. `\"600px\"`, `\"50%\"`) merged into the rendered `<svg>`’s inline style to scale it. The viewBox preserves aspect ratio. When `input` is an IR table, its own `width`/`height`/`maxWidth` fields are used as defaults, and `opts` overrides them.\n\n## mermaid.toSource(input)\nRenders the Mermaid source string from this library’s IR format — useful for debugging or freezing a dynamic diagram into a static block. It delegates to `mermaid.serialize`, a **pure Lua** function defined in this library.\n\n## Views\nThe three `mermaid.*` builders all take a **`pages`** list — a page-object list, typically produced by a `query[[…]]` expression such as `query[[from index.pages(\"adr\")]]` . Each returns a diagram IR you pass to `mermaid.diagram`. Each builder spec also accepts optional `width`, `height`, `maxWidth` (CSS lengths) that are threaded onto the returned IR and applied at render time. An `opts` table passed to `mermaid.diagram` overrides them.\n\n### mermaid.relationGraph(spec)\nA flowchart. Node labels use the page’s last path segment. Clicking still navigates to the full page.\n\nSpec keys:\n * `pages` — the page list to graph, e.g. `query[[from index.pages(\"adr\")]]`.\n * `relations` *(optional)* — frontmatter fields holding `[[page]]` links to draw as edges, e.g. `{\"dependsOn\", \"related\"}`. A `supersededBy` relation is drawn dotted. **When omitted, all relations are auto-detected** — every frontmatter field whose value(s) are `[[links]]` to other pages in the set becomes an edge (labeled by the field name, excluding `groupBy`, which drives subgraph nesting). Pass an explicit `relations` list to restrict edges to specific fields.\n * `groupBy` *(optional)* — a frontmatter field naming a **container** page. Members nest inside that container’s **subgraph**. (The `Architecture` page uses `groupBy = \"partOf\"` to draw the Client / Service Worker / Server layers.)\n * `direction` *(optional)* — `\"LR\"` (default), `\"TD\"`, etc.\n * `color` *(optional)* — a frontmatter field whose value becomes a Mermaid CSS class on each node (e.g. `\"status\"`). Supply matching `classDef`s to style them. Without them the nodes render unstyled. *Auto-`classDef` from observed values is a planned enhancement.)*\n * `max` *(optional, default 60)* — node cap. A “showing N of M” note is added when exceeded.\n\n### mermaid.timeline(spec)\nA mermaid `timeline`: pages laid out chronologically by a date field. (Mermaid timelines have no node click-through, so these entries are not clickable.)\n\nSpec keys:\n * `pages` — the page list to lay out, e.g. `query[[from index.pages(\"journal\")]]`.\n * `dateField` *(default `\"date\"`)* — frontmatter field holding the date (`YYYY-MM-DD…`). Pages without a parseable date are skipped.\n * `groupBy` *(default `\"year\"`)* — `\"year\"` groups events under their year. `\"none\"` emits one entry per date.\n * `labelField` *(optional)* — frontmatter field to use as the event label (defaults to the page’s last path segment).\n * `title` *(optional)* — diagram title.\n * `max` *(optional, default 100)* — event cap. A “showing N of M” note is added when exceeded.\n\n### mermaid.distribution(spec)\nA pie counting the given pages by a categorical frontmatter field (slices sorted count-descending).\n\nSpec keys:\n * `pages` — the page list to count.\n * `by` *(required)* — the frontmatter field to count by, e.g. `\"status\"`.\n * `emptyLabel` *(optional)* — bucket label for pages missing/blank on `by`. Omit to exclude them.\n * `title` *(optional)* — chart title.\n * `showData` *(optional)* — when truthy, renders the raw counts next to each slice (`pie showData`).\n\n## Diagram IR — build any diagram\nFor full control, pass a table instead of a string. It’s a generic *element-stream*: a `type` plus an ordered list of `elements`. Because a `raw` element passes a literal Mermaid line through untouched, **any** diagram Mermaid supports is expressible, structured element kinds are just sugar for the common graph cases.\n\n${mermaid.diagram{\n  type = \"flowchart\",\n  direction = \"LR\",\n  elements = {\n    { kind = \"node\", id = \"a\", label = \"Start\", shape = \"rounded\" },\n    { kind = \"node\", id = \"b\", label = \"Done\" },\n    { kind = \"edge\", from = \"a\", to = \"b\", label = \"go\", arrow = true },\n    { kind = \"click\", id = \"a\", target = \"Some Page\" },\n    { kind = \"raw\",  text = \"%% any literal mermaid line\" },\n  },\n}}\n\nElement kinds:\n\n* `node`: `id`, optional `label`, optional `shape` (`rect`, `rounded`, `stadium`, `circle`, `diamond` or `hexagon`), and optional `class`.\n* `edge`: `from`, `to`, optional `label`, optional `style` (`solid`, `dotted` or `thick`), and optional `arrow`.\n* `subgraph`: `id`, optional `label`, and `elements`.\n* `classDef`: `name` and `style` (a table of CSS properties).\n* `click`: `id` and `target` (the page to navigate to).\n* `raw`: `text` (a literal Mermaid line).\n\nTop level: `type` (e.g. `\"flowchart\"` — any Mermaid type), `direction?` (`\"LR\"`/`\"TD\"`/…), `title?`, `elements`.\n\n### How it works\n1. Your Lua builds the **IR** table (or a `mermaid.*` builder does, from a `pages` list you queried out of the object index).\n2. `mermaid.diagram` serializes the IR to Mermaid source via `mermaid.serialize` that owns id-sanitization, label escaping, and validation.\n3. It calls `mermaid.render` to render it as a SVG.\n4. Node clicks are handled for navigation.\n\nStatic ` ```mermaid ` fenced blocks go through the very same path: at the end of this library’s Space Lua block, `codeWidget.define{ language = \"mermaid\", render = ... }` registers a Core code widget whose `render` simply calls `mermaid.diagram(body)`. So static and dynamic diagrams share one renderer.\n\n# Configuration\nEverything works out of the box, but you can override the defaults via Space Lua config:\n\n```lua\nconfig.set(\"mermaid\", {\n  -- ESM URL imported when no local bundle is installed (default: esm.sh).\n  -- Also the URL the \"Download bundle for offline use\" command fetches from:\n  cdnUrl = \"https://esm.sh/mermaid@11.4.0?bundle\",\n  -- Space path the offline bundle is written to / loaded from:\n  bundlePath = \"Library/silverbullet-diagram/mermaid.bundle.js\",\n})\n```\n\nAll keys are optional. By default diagrams load from `cdnUrl`.
