* `dontWrapPythonPrograms ? false`: Skip wrapping of Python programs.
* `permitUserSite ? false`: Skip setting the `PYTHONNOUSERSITE` environment
variable in wrapped programs.
* `pyproject`: Whether the pyproject format should be used. As all other formats
are deprecated, you are recommended to set this to `true`. When you do so,
`pypaBuildHook` will be used, and you can add the required build dependencies
from `build-system.requires` to `build-system`. Note that the pyproject
format falls back to using `setuptools`, so you can use `pyproject = true`
even if the package only has a `setup.py`. When set to `false`, you can
use the existing [hooks](#setup-hooks) or provide your own logic to build the
package. This can be useful for packages that don't support the pyproject
format. When unset, the legacy `setuptools` hooks are used for backwards
compatibility.
* `makeWrapperArgs ? []`: A list of strings. Arguments to be passed to
[`makeWrapper`](#fun-makeWrapper), which wraps generated binaries. By default, the arguments to
[`makeWrapper`](#fun-makeWrapper) set `PATH` and `PYTHONPATH` environment variables before calling
the binary. Additional arguments here can allow a developer to set environment
variables which will be available when the binary is run. For example,
`makeWrapperArgs = ["--set" "FOO" "BAR" "--set" "BAZ" "QUX"]`.
::: {.note}
When `__structuredAttrs = false`, the attribute `makeWrapperArgs` is passed as a space-separated string to the build script. Developers should use `prependToVar` or `appendToVar` to add arguments to it in build phases, or use `__structuredAttrs = true` to ensure that `makeWrapperArgs` is passed as a Bash array.
For compatibility purposes,
when `makeWrapperArgs` shell variable is specified as a space-separated string (instead of a Bash array) in the build script, the string content is Bash-expanded before concatenated into the `wrapProgram` command. Still, developers should not rely on such behaviours, but use `__structuredAttrs = true` to specify flags containing spaces (e.g. `makeWrapperArgs = [ "--set" "GREETING" "Hello, world!" ]`), or use -pre and -post phases to specify flags with Bash-expansions (e.g. `preFixup = ''makeWrapperArgs+=(--prefix PATH : "$SOME_PATH")`'').
:::
* `namePrefix`: Prepends text to `${name}` parameter. In case of libraries, this
defaults to `"python3.8-"` for Python 3.8, etc., and in case of applications to `""`.
* `pypaBuildFlags ? []`: A list of strings. Arguments to be passed to `python -m build --wheel`.
* `pythonPath ? []`: List of packages to be added into `$PYTHONPATH`. Packages
in `pythonPath` are not propagated (contrary to [`propagatedBuildInputs`](#var-stdenv-propagatedBuildInputs)).
* `preShellHook`: Hook to execute commands before `shellHook`.
* `postShellHook`: Hook to execute commands after `shellHook`.
* `removeBinByteCode ? true`: Remove bytecode from `/bin`. Bytecode is only
created when the filenames end with `.py`.
* `setupPyGlobalFlags ? []`: List of flags passed to `setup.py` command.
* `setupPyBuildFlags ? []`: List of flags passed to `setup.py build_ext` command.
The [`stdenv.mkDerivation`](#sec-using-stdenv) function accepts various parameters for describing
build inputs (see "Specifying dependencies"). The following are of special
interest for Python packages, either because these are primarily used, or
because their behaviour is different:
* `nativeBuildInputs ? []`: Build-time only dependencies. Typically executables.
* `build-system ? []`: Build-time only Python dependencies. Items listed in `build-system.requires`/`setup_requires`.
* `buildInputs ? []`: Build and/or run-time dependencies that need to be
compiled for the host machine. Typically non-Python libraries which are being
linked.
* `nativeCheckInputs ? []`: Dependencies needed for running the [`checkPhase`](#ssec-check-phase). These
are added to [`nativeBuildInputs`](#var-stdenv-nativeBuildInputs) when [`doCheck = true`](#var-stdenv-doCheck). Items listed in
