Plugin for setuptools to build FreeBSD pkg

Project description

Plugin for setuptools that provides bdist_pkg command for building FreeBSD package artifact.

How to use?

Simply add setuptools-pkg to setup_requires in your


Once it’s done, the bdist_pkg command will be available to produce dist/myproject-1.0.0.tgz artifact.

If you don’t want or just cannot have build-time dependencies, same effect can be reached by installing setuptools-pkg as regular Python package.

If you need to build (actually, you want) txz packages and you’re using Python 2, you should specify lzma-2.7 extra to have lzma support. For Python 3 there is no need in this since it’s available out-of-the box.

Advanced usage

Ok, that was too easy. In real world, things are not as easy as we would like to have them.

Each project has dependencies, unless it’s lucky one. For packages we would like to preserve that information, but suddenly, packages in FreeBSD may be named differently from PyPI or be of the different version because of included patches. That’s said, we need the mapping between them. Let’s pick this project as an example:

    # Typically, our dependencies looks like this:
        'lzma-2.7': [
    # The `command_options` is the way to specify parameters for setuptools
    # commands from the `setup()` call. Alternatively, you can do that in
    # `setup.cfg`.
        # bdist_pkg is the name of command setuptools_pkg provides
        'bdist_pkg': {
            # The requirements mapping itself. The __file__ instructs
            # setuptools from where these values came from. Required.
            # The rest is our mapping.
            'requirements_mapping': (__file__, {
                # The key of this mapping is an exact value of a requires
                # list.
                'setuptools>=18.2': {
                    # The value is a FreeBSD pkg metadata: package name,
                    # origin and version.
                    'name': 'py27-setuptools',
                    'origin': 'devel/py-setuptools',
                    # In our example setuptools>=18.2 tells us to pick
                    # any version of setuptools greater than 18.2 and we
                    # explicitly picks package with strict version 20.0.
                    # Please note, that version field is required while
                    # it's not in MANIFEST file.
                    'version': '20.0'
                # Mapping for extras is optional till the moment you
                # want to make a package with these extras on.
                'backports.lzma==0.0.6': {
                    'name': 'py27-backports_lzma',
                    'origin': 'devel/py-backports_lzma',
                    'version': '0.0.6'
            # bdist_pkg turns all the extras into options and through
            # selected options you can choose which ones will be enabled
            # for a package. By default all the options are in "off" state.
            'selected_options': [

Common pitfalls here:

  1. Requirements mapping is not portable. In your pkg repository there could be different versions and different package namings.

  2. Requirements mapping should be up to date.

  3. There is no checks that mapping items are correct. You should pay attention to what you put there.

  4. Having requirements.txt instead of using install_requires in will make your life harder since, technically, your project has no dependencies and we cannot help you there to keep it consistent. You’ll have to specify deps command property directly and bdist_pkg could not ensure that you have there all the packages that project actually uses.

That’s could be found quite boring. However, if all your dependencies in pkg repository are names same as on PyPI and has Python version prefix (like py35-setuptools), than requirements mapping is optional. You can just make package with:

python bdist_pkg --use-pypi-deps

Expert usage

In expert mode you may configure package generation in the way you like. Here is the complete list of options you may specify for bdist_pkg:

  • abi and arch: FreeBSD arch and ABI for which package is made. You must specify them manually if you build package on non-FreeBSD system or if you distribution is not pure.

  • categories: A list (literally) of package categories. By default uses description field of project metadata.

  • comment: Comment is a one-line description of this package. By default uses description field of project metadata.

  • deps: Package dependencies. Sometimes package may depend on non Python projects, like those who provides services or libraries against which your projects dynamically links. The format of deps specification is the same as in +MANIFEST file, except it’s Python dict, not JSON or UCL. For Python dependencies check the requirements_mapping below.

  • desc: A longer description of the package. By default uses long_description field of project metadata.

  • groups: A list of groups to provide.

  • license: Project license. By default uses license field of project metadata.

  • maintainer: The maintainer’s mail address. Python distributions defines both maintainer and author entities who rules the package. By default, the maintainer one is picked if available with fallback to author in case when it’s not.

  • name: Package name. Since FreeBSD packages often uses own naming policy, the custom name can be used instead of real project one.

  • options: Package options. By default, this list is filled from the extras.

  • selected_options: List of options which are used for this package build.

  • origin: By default the generic origin devel/py-{project_name} is set.

  • prefix: The path where the files contained in this package are installed (usually /usr/local).

  • provides: A list of features/services packages provides.

  • requires: A list of features/services packages paquires.

  • requirements_mapping: Mapping between PyPI requirements and FreeBSD packages. This mapping helps to ensure that all the dependencies specified in install_requires and extras_require will be satisfied through system packages. The result fills the deps option.

  • scripts: Package scripts.

  • users: A list of users to provide.

  • version: Package version. As like package name, can be different from real project version, depending on local modifications, patches, epoch etc.

  • www: Project URL.


  • How it’s different from pytoport?

    The pytoport project generates ports from modules on PyPI. It does great job on this, but bdist_pkg solves a different problem, especially, when your project cannot be published on PyPI.

  • How can I make a package for some arbitrary Python project?

    You have to patch it first to let him produce proper package with the deps, metadata and else bits. But seriously, you better use ports all the time.

  • If I should use ports to make packages, why this project exists?

    In my case we have a couple of in-house projects which we package directly without using any ports or cooking Makefiles.
