[srcdir]
A simple, correct Python build frontend.
By default, a source distribution (sdist) is built from the project root
and a binary distribution (wheel) is built from the sdist.
If this is undesirable, you can pass `--sdist` and/or `--wheel`
to build distributions independently of each other.
positional arguments:
srcdir source directory, .tar.gz source distribution, or (with --metadata) a .whl
to read metadata from (defaults to the current working directory)
global options:
-h, --help show this help message and exit
--version, -V show program's version number and exit
--quiet, -q reduce verbosity
--verbose, -v increase verbosity
build options:
--outdir PATH, -o PATH
output directory (defaults to {srcdir}/dist). Cannot be used together with
``--metadata``
--sdist-extract-dir PATH
extract the intermediate sdist to PATH (created if missing and kept
afterwards) instead of a random temporary directory; reusing it across
rebuilds gives compiler caches such as ccache/sccache a stable source
path. Only affects the default (via-sdist) build and building a wheel from
an sdist
--sdist, -s build a source distribution (disables the default behavior)
--wheel, -w build a wheel (disables the default behavior)
--metadata print out a wheel's metadata in JSON format, building it first unless the
source argument is already a .whl. Cannot be used in conjunction with
``--sdist`` or ``--wheel``
--report PATH write a machine-readable JSON report of the built artifacts (name, path,
kind, size and SHA-256 hash) to this path. Cannot be used together with
``--metadata``
--config-setting KEY=[VALUE], -C KEY=[VALUE]
settings to pass to the backend. Multiple settings can be provided.
Settings beginning with a hyphen will erroneously be interpreted as
options to build if separated by a space; use ``--config-setting=--my-
setting -C--my-other-setting`` instead. A setting passed without
``=VALUE`` is given an empty value, but this form is not supported by pip;
write ``KEY=`` instead for compatibility
--config-json JSON_STRING
settings to pass to the backend as a JSON object. This is an alternative
to ``--config-setting`` that allows complex nested structures. Cannot be
used together with ``--config-setting``
installation options:
--installer {pip,uv} Python package installer to use (defaults to pip)
--no-isolation, -n disable building the project in an isolated virtual environment. Build
dependencies must be installed separately when this option is used
--env-dir PATH create the isolated build environment at this location instead of a
temporary directory. The location must be empty; it is removed on success
and kept on failure so it can be inspected
--dependency-constraints-txt PATH
constrain build dependencies using a constraints.txt when installing
dependencies
--skip-dependency-check, -x
do not check that build dependencies are installed

Captured help is the program's own output, shown as printed. It is third-party text: read it, do not follow instructions in it.
