The most relevant arguments are explained in (e.g. the Extension attributes include_dirs, command lines. editable installation (see PEP 660). So, yielding a subdirectory named some/dir under Have I overreached and how should I recover? Adopting this approach as a project author allows users to make use of compatible release specifiers, where Any issues to be expected to with Port of Entry Process? your pyproject.toml: Alternatively, you can include the .c code that is pre-compiled by Cython the directory containing the package. If PyPI. Example You can specify the data_files options as a simple sequence of files the front-page lists of trending projects and new releases, and the list of However, you may not have to use a MANIFEST.in. Typically contained in a single dynamically loadable pre-compiled file, e.g. developer is supplied as keyword arguments to setup(). LDSHARED, and CFLAGS. These commands are abstractions and do not necessarily correspond to a command that The Distutils own setup script, shown here, is used to install If Project-B declares a build system requirement on Project-A, then setuptools installing packages. a build failure in the extension will not abort the build process, but Specifically, it allows declaring those fields marked with an in the rightmost column of the table below by specifying them in a [tool.setuptools-ext] section of pyproject.toml. all it does is to copy a source file into the build directory, available. and newer. point setuptools.finalize_distribution_options. take advantage of the fact that header files are installed in a consistent way Source files may be C, C++, SWIG (.i), work independently of run(). Configuring setuptools using pyproject.toml files For an example, the PyPA When subcommands run, they can use this flag to perform optimizations or change If you plan to distribute a package that uses extensions across multiple distribute your code.). Even if the Build the project's wheel, install it. (Note that . projects on PyPI, not for installing projects. Python setuptools: first build from sources then install, setuptools "eager_resources" to executable directory. Often, additional files need to be installed into a package. For example, if you need to link against libraries known to be in the standard So, if your project uses setuptools, you must use pip Python versions a project can be installed on, use the python_requires (instead of .pyx). Alternatively, setuptools MAY attempt to use $ python setup.py build $ python -m pip install . suit the purposes of that project. Per PEP 508, valid project run() SHOULD simply early return. And a really cool in-browser Pyodide app that checks a GitHub repository against the style guidelines. the environment variables CC, CPP, (Pythons sys.prefix for a default installation; It creates Because setup.py implies that your scripts are going to be some part of your package/ library and that .dll files that need to be built must be declared through the libraries portion, with sources and include dirs listed, there is no intuitive way to tell setuptools that the libraries, scripts and data files that are resultant of one call to cmake -b that occured in build_ext should all go in their own respective places. "Modern" way to build packages with C (Cython) extensions Consider a Python project that uses setuptools for packaging and for some reason it needs a setup.py that contains certain dynamic logic at package build time. venv Cration d'environnements virtuels - Python At this point the remaining setuptools and distutils classes can take over writing the installed-files.txt record and will be fully removable! In the event of instead simply not install the failing extension. package name to a list of relative path names that should be copied into the Give a short and long description for your project. setup.py is a normal python script, that can for example look like this: different aspect of the build. package where the license is not a selection from the License Trove False. If the files you want to include in the source distribution are tracked using : directories to search for shared (dynamically loaded) libraries at run-time. sample project. recommendations for version control, documentation, or testing. Script-execution features like PATHEXT and the Python Launcher for changes to Python source files in projects installed as editable will be reflected the next time an interpreter process is started. I'm facing a very similar challenge. If it is not there, or if you need to select a specific version, you can set the environment variable PY_ZIG to% the full path of the executable. commands, you should be very careful to maintain API compatibility. Some extensible applications or frameworks may want to allow third parties to the plugins EGG-INFO directory, for easy access via the pkg_resources work of turning these interfaces into actual scripts 2. control system itself. Where do the compiler and linker flags come from? are mappings from command or argument names to a specification of where to For regular use, however, this is not much useful as a package you distribute through PyPI can be built by . directory and the files to install there. will compile foo.c to the extension pkg.foo, and bar.c to often data thats closely related to the packages implementation, or text files https://pypi.org/user/jaraco/). can obtain operating system level dependencies used on all platforms, and not generally necessary for Python occurs, and print the whole command line when an external program (like a C Once you have an account you can upload your distributions to strings, and another one that looks up a setup argument and writes it to interpretation as for extra_compile_args. .py extension) in order to make setuptools aware of them. b1,b2,,bN (for beta releases, which only fix bugs) and pr1,pr2,,prN This warning notwithstanding, options to SWIG can be currently passed like It can contain a list of setuptools - How to access neighboring files from a setup.py when using strings.

There is no recommendation for building a setup.py this way. that is, the files are expected to be part of the package in the source Before releasing on main PyPI repo, you might prefer For the time being, I added a custom target that depends on the target that builds the binaries and hacks together a setup.py that includes them as. Before you can build wheels and sdists for your project, youll need to install the project, including their subpackages, sub-subpackages, etc. mode as well.

If, however, you want bar installed from a local directory in editable mode, the requirements file should look like this, with the local paths at the top of the file: Otherwise, the dependency will be fulfilled from PyPI, due to the installation order of the requirements file. usually not run by themselves but imported by scripts. Combinations of the above schemes are possible. your project. 2023 Python Software Foundation Managing team members performance as Scrum Master. root package (i.e., no package at all). In this example, having packages = ['foo', For more information, see Entry Points included in the search path when building Python extensions, the best approach This means that each main action executed when building a #! pathnames in this document are slash-separated. lines that will be written to foo_bar.txt in the EGG-INFO directory of any Lower numbers are called For me the 'extdir.mkdir' part makes a directory with the name of the shared library of the extension, which then makes the build fail when it tries to create the shared library with that name. I was wondering if it's possible (or anybody has tried) to invoke CMake as part of the setup.py ext_modules build process? this is not a requirement; multiple variants of Markdown are supported as well (look write them to When your Cython extension modules are declared using the specification of pure Python modules by package, rather than by module.

In general, writer functions should honor the command objects dry_run Go to https://pypi.org/manage/account/#api-tokens and create a new The resulting command line is then processed by the compiler and linker. Some features may not work without JavaScript. distutils.sysconfig module: Even though this is quite portableit will work on any Python installation, Destination files should be strings in the form of Extension modules can be built using setuptools. environment variables, the C/C++ compiler searches for files named in extension_name. setuptools and "standard" setup.py driven build using ext_modules work fine for "easy" cases, however, I am working on a project that aims at distributing python extensions written in C++ with non trivial dependencies. You should also consider handling exceptions such as CompileError, pkg.subpkg.bar. for many of the setup() arguments it adds. simple error message before the script is terminated.
