Shared git tag-glob resolution for monorepo projects and releasables, deriving tag match patterns from releasable tag_format or detected target.

#rlsbl.tag_glob

#rlsbl.tag_glob

Shared git tag-glob resolution for monorepo projects and releasables.

A single source of truth for deriving the git tag match pattern of a monorepo project. Two code paths previously derived this independently (rlsbl monorepo status and rlsbl status), and one of them ignored the releasable's tag_format -- so releasable members reported no tag. Both now call :func:resolve_monorepo_tag_glob.

#TagMode

Whether :func:parse_version_tag accepts prerelease tags.

FINAL_ONLY rejects any tag carrying a prerelease suffix (v1.2.3-rc.1) -- used by call sites that count or match final releases only. PRERELEASE_INCLUSIVE accepts both final and prerelease tags. There is no default: every call site must state its semantics explicitly so the mode can never silently flip.

#TagVersion

Result of parsing a git tag into a version.

Attributes:

  • version: the x.y.z (optionally -prerelease) string, no v.
  • scheme: which tag scheme matched -- "standalone" (v1.2.3),

"monorepo" (name@v1.2.3), or "path" (path/v1.2.3).

#parse_version_tag

python
def parse_version_tag(tag: str, *, mode: 'TagMode') -> 'TagVersion | None'

Parse a git tag into a :class:TagVersion, or None if it is not a version tag under any known scheme.

Recognizes three schemes, matched against the whole tag (strict):

  • standalone: v1.2.3
  • monorepo: name@v1.2.3
  • Go path-style: some/path/v1.2.3

The version core must be strict semver (x.y.z); milestone-like tags (latest, milestone-3), partial versions (v1.2), and tags with no scheme separator before v are rejected. mode is required and controls whether a prerelease suffix is accepted:

  • :attr:TagMode.FINAL_ONLY -- v1.2.3-rc.1 is rejected (returns None).
  • :attr:TagMode.PRERELEASE_INCLUSIVE -- v1.2.3-rc.1 yields 1.2.3-rc.1.

#releasable_tag_glob

python
def releasable_tag_glob(tag_format: str, releasable_name: str) -> str

Derive a glob from a releasable's tag_format.

Replaces {version} with * and fills in {name} with the literal releasable name so git tag -l matches all versions (e.g. "{name}@v{version}" -> "www@v*").

#_target_tag_scheme

python
def _target_tag_scheme(target, name, path)

Classify a target's monorepo tag scheme.

Returns "at" for the {name}@v* scheme (base default, used by all targets except Go) or "path" for the {path}/v* scheme (Go's path-based module-proxy tags). Classification is derived from the target's own monorepo_tag_glob output so it stays correct if new targets adopt a path-based scheme.

#_mixed_tag_schemes

python
def _mixed_tag_schemes(target_entries, name, path)

Group a member's targets by tag scheme.

Returns a dict {scheme: [target_name, ...]} when the member's targets span more than one tag scheme (the mixed-scheme hazard), otherwise None. Only targets present in TARGETS are considered.

#derive_releasable_tag_format

python
def derive_releasable_tag_format(target_entries, name, path, *, subject)

The tag format an auto-singleton releasable is created with.

Derived from the member's PRIMARY target's monorepo scheme and returned literally: {name}@v{version} for every target but Go, and the Go module proxy's <path>/v{version} for Go. A member whose targets span BOTH schemes has no single answer, so it is a refusal naming --tag-format rather than a silent pick of whichever target was detected first.

Both commands that create a releasable from a member -- monorepo add and monorepo absorb -- derive through here, so the format a member's targets imply is one fact with one answer.

Args:

  • target_entries: the member's detected (or declared) TargetEntry list.
  • name: the releasable's name, which fills {name} in the @-scheme.
  • path: the member's repo-relative path, which the Go path-scheme tags under.
  • subject: how the refusal names what declared the mixed targets

(e.g. "member dir 'packages/widget'").

Raises:

  • MixedTagSchemeError: the member's targets span both tag schemes.

#_mixed_scheme_error

python
def _mixed_scheme_error(project_path, mixed)

Build the hard-error message for a mixed-tag-scheme member dir.

#resolve_monorepo_tag_glob

python
def resolve_monorepo_tag_glob(project, workspace_root, releasable=None) -> str

Return the git tag glob for a monorepo project.

When the project belongs to a releasable (explicit mode), the glob is derived from the releasable's tag_format -- this is the fix for releasable members previously falling back to the per-member target glob and reporting no tag. Otherwise the glob comes from the project's first detected target's monorepo_tag_glob, or "{name}@v*" when no target is detected.

Args:

  • project: a WorkspaceProject or dict with name/path.
  • workspace_root: path to the monorepo root (str or Path).
  • releasable: optional Releasable the project belongs to; when provided,

its tag_format drives the glob.
