Resolve

resolve

Canonical uv-workspace resolution.

Parses [tool.uv.workspace] from a root pyproject.toml, resolves the members globs to directories, applies exclude and the require_pyproject rule, and returns sorted :class:Member records.

STDLIB only (tomllib + pathlib). Defensive parsing: an absent or malformed pyproject never raises -- it yields None.

find_project_root(start)

Walk parents from start to the first directory holding any pyproject.

Returns the directory of the first ancestor (start included) that contains a pyproject.toml -- any project, not necessarily a uv workspace. start is resolved first; a file start is anchored on its parent directory. Unlike :func:find_workspace_root, this never returns None: with no pyproject.toml in any ancestor it falls back to the (resolved) starting directory.

find_workspace_root(path)

Walk parents from path to the first uv-workspace root.

parse_workspace_members(text)

Extract the raw [tool.uv.workspace].members from pyproject text.

Pure-string helper: parses text with :func:tomllib.loads and returns the declared members verbatim -- no glob expansion, no filesystem access, no exclude/require_pyproject filtering. Globs (packages/*) and literal entries are returned exactly as written. Defensive: malformed TOML or an absent [tool.uv.workspace] table yields [] rather than raising.

Parameters:

Name	Type	Description	Default
text	str	Raw pyproject.toml content.	required

Returns:

Type	Description
list[str]	The raw member strings declared under [tool.uv.workspace].members,
list[str]	or [] when none are declared.

resolve_workspace(pyproject_dir)

Resolve the uv workspace rooted at pyproject_dir.

Parses [tool.uv.workspace].members, resolves the globs to directories, subtracts the exclude globs, keeps only directories that contain a pyproject.toml (require_pyproject), and returns the members sorted by name. Returns None when pyproject_dir is not a uv workspace or its pyproject is missing/malformed.
