extract-plugins.py derives addedAt/updatedAt per entry from one `git log --name-status` over plugin-catalog/ (committer dates, so rebase-merged PRs are stamped when they land; renames carry the original addedAt). A shallow checkout or missing git yields null dates instead of wrong ones, and deploy-site.yml now checks out with fetch-depth: 0 so the deploy has the history. The /docs/plugins page gains a Sort control (Most starred / Newest / Recently updated) and an "Added … · Updated …" line on every card; Updated is hidden while it equals Added.

"""Extract plugin-catalog entries into website/static/api/plugins.json.
|
|
|
|
Feeds the Plugin Catalog page at /docs/plugins (website/src/pages/plugins/).
|
|
|
|
Data source: ``plugin-catalog/*.yaml`` at the repo root — one YAML file per
|
|
catalog entry (see plugin-catalog/README.md for the entry schema), plus
|
|
``plugin-catalog/removed.yaml`` listing plugins pulled from the catalog.
|
|
No network, no crawling: the catalog is human-merged data in the checkout.
|
|
|
|
Graceful degradation: when ``plugin-catalog/`` does not exist yet (the
|
|
catalog PR may not have merged), we emit an EMPTY catalog list and zeroed
|
|
meta counts and exit 0 so the docs build stays green. The page renders a
|
|
"catalog is just getting started" state.
|
|
|
|
Outputs (both under website/static/api/, CDN-served at /docs/api/):
|
|
|
|
- ``plugins.json`` — list of catalog entries for the page (camelCase)
|
|
- ``plugins-meta.json`` — counts by tier + generatedAt + removedCount
|
|
- ``plugin-catalog.json`` — ``{"entries": [raw YAML mappings], "removed": [...]}`` in the loader's own
|
|
schema; installed Hermes clients fetch this for live catalog refresh
|
|
(``hermes_cli.plugin_catalog.LIVE_CATALOG_URL``) so new entries and removals reach them without
|
|
updating. Emitting it here means the docs deploy IS the publish step — no second pipeline.
