|
|
|

## `export guidelines`
|
|
|
|
Render the guideline pages into one generated `GUIDELINES.md`, or push it into the captured repositories that opted in (**Guideline Push Gate**).
|
|
|
|
**Synopsis**
|
|
|
|
- `wikitool export guidelines [--field <predicate> ...] [--kind/--subtype/--collection/--tag <v>]` - Prints the file to stdout; no network.
|
|
- `wikitool export guidelines <predicates> --push [--bundle <raw-bundle> ...] [--confirm TOKEN]` - Writes it into the captured repositories, behind the gate.
|
|
|
|
**Options**
|
|
|
|
```text
|
|
-f, --field <str> Frontmatter predicate, repeatable (AND) - the same forms
|
|
as `search --field`.
|
|
--kind <str> Shorthand for --field kind=<value>.
|
|
--subtype <str> Shorthand for --field subtype=<value>.
|
|
--collection <str> Shorthand for --field collection=<value>.
|
|
--tag <str> Shorthand for --field tags=<value>.
|
|
--push Write the file into the captured repositories (Guideline
|
|
Push Gate).
|
|
--bundle <path> Only the repository of this captured bundle under raw/;
|
|
repeatable.
|
|
--confirm <str> The token from a prior exit 42, once a human has approved
|
|
it.
|
|
-h, --help Show this message and exit.
|
|
```
|
|
|
|
**Examples**
|
|
|
|
```bash
|
|
tools/wikitool export guidelines --tag guideline
|
|
tools/wikitool export guidelines --tag guideline --push
|
|
tools/wikitool export guidelines --confirm <token> --push --field tags=guideline # re-run after exit 42, once the user approved every diff
|
|
```
|
|
|
|
**Behaviour**
|
|
|
|
- Selects pages with `search`'s own predicates and no text: `--field` (repeatable, AND), `--kind`, `--subtype`, `--collection`, `--tag`. Which filter selects this instance's guidelines is written down in `kb/CONVENTIONS.md`.
|
|
- Renders mechanically: line 1 is `<!-- wikitool:export kind=guidelines instance=<origin URL without userinfo, or local> commit=<newest commit touching a selected page> - generated, do not edit by hand -->`; then each page sorted by title, as `# <title>` and its text without frontmatter, the generated links and footnote blocks, citation markers (`[^id]`, legacy `^[[...]]`), with `[[Title|Text]]` as `Text` and `[[Title]]` as `Title`. A leading H1 of the page is replaced by the title heading. Code is never rewritten. LF endings, no timestamp: the same pages give the same bytes.
|
|
- Refuses before printing or pushing anything: no predicate, no match, an unknown field, any page under `kb/` with unreadable frontmatter, uncommitted changes in `kb/` or `types/` (untracked files included), or no git checkout.
|
|
- `--push` targets every captured repository - each `(repo, ref)` from a `_capture.json` under `raw/`, `--bundle` narrowing it. A target is skipped with its reason when its ref rule is a tag pattern, it cannot be reached or has no such branch, its root has no `GUIDELINES.md` (not opted in), its `GUIDELINES.md` has no export header (hand-written), or the header names another `instance=`. A header line alone is the opt-in.
|
|
- Guideline Push Gate: `--push` without a matching `--confirm` fetches and builds everything, pushes nothing, and exits 42 with each target's status (`new`, `changed`, `unchanged`, `skipped`), the diff for every target it would write, and the re-run line. The token digests URL, branch, old tip and new blob of every target to write.
|
|
- With a matching token, each target gets exactly one commit on the fetched tip changing only `GUIDELINES.md`, authored as the instance checkout's `user.name`/`user.email`, pushed without force; one line per target: `unchanged`, `written <old> -> <new>`, `skipped (<reason>)`, `rejected (<reason>)` or `failed (<reason>)`.
|
|
- Nothing to write (every target unchanged or skipped) ends with exit 0 and no gate. A second run after a successful one finds every target unchanged.
|
|
- The target repository's own `AGENTS.md` points at the file (Claude Code: `@GUIDELINES.md`); that belongs to the repository, not to this command.
|
|
|
|
**Properties**
|
|
|
|
- Changes files: yes
|
|
- Idempotent: yes
|
|
- Atomic: Per target - one commit pushed without force, or nothing; targets already written stay written when a later one fails
|
|
- Counts toward the session call budget: yes
|
|
- Can reach the network: yes
|
|
- Gates: guideline-push - see [exit codes and gates](../exit-codes.md)
|
|
|
|
**Exit codes**
|
|
|
|
- `0` - success
|
|
- `0` - A target was skipped - tag rule, not reachable, not opted in, hand-written file, another instance's file
|
|
- `1` - No predicate, no page matches, a malformed predicate or an unknown field
|
|
- `1` - A page under `kb/` has unreadable frontmatter, `kb/` or `types/` has uncommitted changes, or the instance is not a git checkout
|
|
- `1` - `--push` with no `user.name` or `user.email` in the instance checkout's git configuration - checked before any target is fetched
|
|
- `1` - `--bundle` names no captured bundle under `raw/`, or `--bundle`/`--confirm` was given without `--push`
|
|
- `1` - A target rejected the push (its branch moved since the fetch) or a git call failed - the other targets were still served
|
|
- `42` - Guideline Push Gate: `--push` without `--confirm`, or with a token that does not match the current set of targets

## `export run`
|
|
|
|
Write the derived, read-only reading copy of `kb/` into the folders the `export` section configures - the selected pages as Markdown, or converted by a program of this checkout.
|
|
|
|
**Synopsis**
|
|
|
|
- `wikitool export run [<target> ...]` - Every configured target, or the named ones. Needs an `export` section in `.wikitool-local.json`; the user writes it by hand.
|
|
|
|
**Options**
|
|
|
|
```text
|
|
Arguments:
|
|
[TARGET]... Targets to run; default: every configured target.
|
|
|
|
Options:
|
|
-h, --help Show this message and exit.
|
|
```
|
|
|
|
**Examples**
|
|
|
|
```bash
|
|
tools/wikitool export run
|
|
tools/wikitool export run work-notes
|
|
```
|
|
|
|
**Behaviour**
|
|
|
|
- An export is derived: regenerated from `kb/` on every run, never edited, never read back into the wiki. Each target names its pages with an allowlist of `search --field` predicates (`include`: a list of selections, AND within one, OR across them), a handler (`markdown`, or `command` for the operator's converter) and the folder (`path`, outside the instance). Nothing is exported that no selection names.
|
|
- Every Markdown file starts with a frontmatter block whose `wikitool_export` line says `kind=pages instance=<origin URL without userinfo, or local> commit=<newest commit touching this page>`, followed by `title`, `type`, `summary`, `modified` where the page has them (`frontmatter: summary`, the default; `minimal` keeps only the marker, `full` the whole frontmatter), then the page text. A file keeps its path below `kb/`. A wikilink to an exported page becomes a relative Markdown link (`links: relative`, the default) or plain text (`links: text`); a link to a page that is not exported is always plain text. Footnote markers stay; code is never rewritten. LF endings, no timestamp: the same pages give the same bytes, and a commit that touches one page rewrites that page's file alone - plus any file whose links change because a page entered or left the selection. The manifest's `commit` is the newest commit touching any selected page; all of them come from one `git log`, however many pages are selected.
|
|
- Handler `command`: the Markdown is rendered into a staging directory, the program of `export.commands` runs with no shell, stdin closed and a timeout of 300 s, and receives the Markdown directory and an empty output directory as its last two arguments. On exit 0 the regular files in the output directory (recursively) become the target's content; any other end leaves the target unchanged and prints the end of its stderr. The staging directory is always removed.
|
|
- The folder is only ever touched by what it holds in its manifest, `.wikitool-export.json`: the files an earlier run wrote, each with its sha256. A run removes only manifest files that are no longer exported (and folders it created, once empty), rewrites a manifest file that is missing, leaves every other file byte for byte as it was, and writes nothing - not even a modification time - for a file that did not change. A run that changes nothing writes nothing at all.
|
|
- Refuses a target, before writing anything into it: a non-empty folder with no manifest (it is somebody's, not an export), a manifest file that was changed in the folder since the last run (naming it), a foreign file where an exported one belongs, an empty selection (it would delete the earlier export), an unknown field in a predicate. A missing folder is created.
|
|
- Refuses everything, before any target: uncommitted changes in `kb/` or `types/` (untracked files included), no git checkout, a page under `kb/` with unreadable frontmatter, an unknown target name, a broken `export` section.
|
|
- Output per target: `new` (with the page titles), `changed`, `removed`, the count `unchanged`, or `failed` with the reason. A page that newly enters a selection is reported as new, not gated. Exit 0 when every target ran; exit 1 when any failed - the others were still served.
|
|
- A target with `after_publish: true` is also refreshed by every `publish` that committed, `--no-push` included; a failure there is a warning, the commit stands, and this command is the repeat.
|
|
- `raw accept` refuses a file whose sha256 a target's manifest lists, and one that carries the marker: an export never goes back into `raw/`.
|
|
|
|
**Properties**
|
|
|
|
- Changes files: yes
|
|
- Idempotent: yes
|
|
- Atomic: Per file within a target (a temporary file in the target, then a move over its place), the manifest last; targets are independent, so a failed target does not undo another
|
|
- Counts toward the session call budget: yes
|
|
- Can reach the network: no
|
|
|
|
**Exit codes**
|
|
|
|
- `0` - success
|
|
- `1` - No `export` section, an unknown target name, or a broken section (a predicate that does not parse, a path inside the instance or in the way of another target, an `intake` folder or the backup target)
|
|
- `1` - `kb/` or `types/` has uncommitted changes, the instance is not a git checkout, or a page under `kb/` has unreadable frontmatter
|
|
- `1` - A target failed: a foreign folder, a file changed in the target, an empty selection, an unknown field, a converter that did not exit 0
