"""Build a published update manifest from a plugin repo's curated inputs.
|
||
|
||
Inputs (all WP-native / YAML, all export-ignored from the shipped zip):
|
||
.mu-manifest.yaml curated base — name/homepage/author/tags + optional section
|
||
OVERRIDES (inline HTML, or `@path.(md|html|txt)` includes).
|
||
.mu-release.yaml pipeline config (passed via --config): sections.autogen,
|
||
sections.strip_title, channel, app_build.
|
||
readme.txt the WordPress readme — its `== Section ==` blocks are the
|
||
DEFAULT modal sections (Description / Installation / FAQ /
|
||
Changelog / …). The `=== Title ===` header + the tag block
|
||
are naturally skipped (they aren't `== … ==`).
|
||
CHANGELOG.md changelog fallback, used only if readme.txt has no Changelog.
|
||
|
||
SECTIONS cascade, per modal key: .mu-manifest.yaml override > readme.txt block
|
||
( + changelog: ... > readme.txt == Changelog == > CHANGELOG.md ).
|
||
|
||
readme.txt is a markdown subset; its `= Subhead =` lines render as bold paragraphs
|
||
(not <h4>) because WP's modal puts `clear:both` on headings, which — when a section
|
||
LEADS with one — drops the body below the floated sidebar (a big top gap). For the
|
||
same reason a leading <h1–6> is demoted to <p><strong>…</strong></p>. `strip_title`
|
||
(null|bool|dict) removes a leading H1 from parsed markdown before that.
|
||
|
||
Computed fields (--computed) always win for release-critical/readme-derived keys;
|
||
the curated base wins for everything else it provides.
|
||
|
||
Usage:
|
||
build-manifest.py --repo-root . --computed computed.json --out out.json [--config .mu-release.yaml]
