| """Update the pinned CDDL spec files downloaded from w3c/webref. | ||
|
|
||
| The WebDriver BiDi (and related) CDDL grammars are not published as an npm | ||
| package; they are extracted from the edited specs and committed to the | ||
| ``ed/cddl`` directory of https://github.com/w3c/webref . We pin a single | ||
| webref commit plus a sha256 for the ``-all`` (union) CDDL file of each | ||
| protocol in that directory (see ``common/webref_cddl.bzl``) so the Bazel | ||
| build fetches them reproducibly. The per-end ``-local``/``-remote`` splits are | ||
| skipped: generation merges the union, so only the ``-all`` files are consumed. | ||
|
|
||
| This script repoints that pin at the tip of webref's "main" branch (the | ||
| continuous reffy extraction; the "curated" branch is a separate published | ||
| lineage with no shared history, so main keeps pin-to-pin diffs auditable), | ||
| refreshes every hash, and picks up files that upstream has added or removed. | ||
| Because the file set drifts over time, it regenerates both: | ||
|
|
||
| - the ``_COMMIT`` and ``_CDDL_FILES`` entries in ``common/webref_cddl.bzl`` | ||
| - the matching ``use_repo(...)`` list for the extension in ``MODULE.bazel`` | ||
|

| usage: update_cddl.py [-h] [--commit COMMIT] [--branch BRANCH] | ||
|
|
||
| options: | ||
| -h, --help show this help message and exit | ||
| --commit COMMIT pin this exact webref commit instead of the branch tip | ||
| --branch BRANCH webref branch to resolve when --commit is omitted (default: main) | ||
