Returns ``None`` when ``[project]`` is missing, malformed, or ``project.dynamic`` includes ``dependencies``, ``optional-dependencies``, ``version``, or ``requires-python`` (the field cannot be trusted as static). Returns a :class:`WheelMetadata` shape when the static fields are authoritative, populating ``name``, ``version``, ``requires_python``, ``requires_dist``, and ``provides_extra``. Raises :class:`BuildBackendError` when the file is there but cannot be read. Its contents are unknown, so it is neither "no static metadata" nor a missing file; the message names the errno. Raises :class:`InvalidProjectRequirementError` when a present, non-dynamic field is corrupt: a structurally wrong ``dependencies`` / ``optional-dependencies`` (not an array of strings / not a table), a ``version`` string that does not parse as :pep:`440`, or a ``requires-python`` that is not a string or does not parse as a specifier. A corrupt static value is not something the build backend can compute, so it raises rather than deferring to a build of the same broken file. The returned ``provides_extra`` includes both the lower-cased keys of ``project.optional-dependencies`` and any extras declared via PEP 685 markers in ``requires-dist``. PEP 685 normalisation is applied to all extra names. Cached per ``source_dir``: the static fields are deterministic derivations of the on-disk ``pyproject.toml``, and a universal resolve reads the same workspace member's file once per matrix tuple. Callers must treat the returned :class:`WheelMetadata` as read-only. zpyproject.tomlNzutf-8)encodingz!could not read pyproject.toml at : ) r should_read read_textOSErrorr rUnicodeDecodeErrorr _project_to_metadata)r pyprojecttextexcmsgprojects& rextract_static_metadatar,*sH--I i , , , ""G"4"$'G  (( s##5j\C5IC#C(c 1 s#A B!%B  BBBc V^8dQhRRRR/#)rr+dictrrr)rs"rrrbs  $ +? rc VPR4pVPR4p\V\4'd\V\4'gR#VPR4p\V\4'dRV9gRV9dR#\ V4p\TPR44p\\T4TT\T4\\T44R7# \ dpRT: RT 2p\ T4ThRp?ii;i) z?Convert a static ``[project]`` table to :class:`WheelMetadata`.nameversionNdynamiczrequires-pythonzinvalid [project].version r!)r0r1requires_python requires_distprovides_extra) get isinstancestrlistr ValueErrorr_static_requires_pythonr r_collect_requires_distsorted_collect_provides_extra)r+r0 version_rawr2r1r)r*r3s& rr&r&bs ;;v D++i(K dC ;(D(Dkk)$G'4  W 1W <;+& .gkk:K.LMO  t $',W55g>?   ;*;/C5A,S1s:;s C"" D-DDc V^8dQhRRRR/#)rrawobjectrzSpecifierSet | Noner)rs"rrrs,?rcVfR#\V\4'g$R\V4P 2p\ V4h\ V4p\ V4V# \dpRT: RT 2p\ T4ThRp?ii;i)aParse a static ``requires-python``, raising when it is corrupt.
