As shown in section A Simple Example, you use the sdist command to create a source distribution. In the simplest case,
python setup.py sdist
(assuming you haven’t specified any sdist options in the setup script or config file), sdist creates the archive of the default format for the current platform. The default format is a gzip’ed tar file (.tar.gz) on Unix, and ZIP file on Windows.
You can specify as many formats as you like using the --formats option, for example:
python setup.py sdist --formats=gztar,zip
to create a gzipped tarball and a zip file. The available formats are:
|zip||zip file (.zip)||(1),(3)|
|gztar||gzip’ed tar file (.tar.gz)||(2),(4)|
|bztar||bzip2’ed tar file (.tar.bz2)||(4)|
|ztar||compressed tar file (.tar.Z)||(4)|
|tar||tar file (.tar)||(4)|
If you don’t supply an explicit list of files (or instructions on how to generate one), the sdist command puts a minimal default set into the source distribution:
Sometimes this is enough, but usually you will want to specify additional files to distribute. The typical way to do this is to write a manifest template, called MANIFEST.in by default. The manifest template is just a list of instructions for how to generate your manifest file, MANIFEST, which is the exact list of files to include in your source distribution. The sdist command processes this template and generates a manifest based on its instructions and what it finds in the filesystem.
If you prefer to roll your own manifest file, the format is simple: one filename per line, regular files (or symlinks to them) only. If you do supply your own MANIFEST, you must specify everything: the default set of files described above does not apply in this case.
Changed in version 3.1: An existing generated MANIFEST will be regenerated without sdist comparing its modification time to the one of MANIFEST.in or setup.py.
Changed in version 3.1.3: MANIFEST files start with a comment indicating they are generated. Files without this comment are not overwritten or removed.
Changed in version 3.2.2: sdist will read a MANIFEST file if no MANIFEST.in exists, like it used to do.
The manifest template has one command per line, where each command specifies a set of files to include or exclude from the source distribution. For an example, again we turn to the Distutils’ own manifest template:
include *.txt recursive-include examples *.txt *.py prune examples/sample?/build
The meanings should be fairly clear: include all files in the distribution root matching *.txt, all files anywhere under the examples directory matching *.txt or *.py, and exclude all directories matching examples/sample?/build. All of this is done after the standard include set, so you can exclude files from the standard set with explicit instructions in the manifest template. (Or, you can use the --no-defaults option to disable the standard set entirely.) There are several other commands available in the manifest template mini-language; see section Creating a source distribution: the sdist command.
The order of commands in the manifest template matters: initially, we have the list of default files as described above, and each command in the template adds to or removes from that list of files. Once we have fully processed the manifest template, we remove files that should not be included in the source distribution:
Now we have our complete list of files, which is written to the manifest for future reference, and then used to build the source distribution archive(s).
You can disable the default set of included files with the --no-defaults option, and you can disable the standard exclude set with --no-prune.
Following the Distutils’ own manifest template, let’s trace how the sdist command builds the list of files to include in the Distutils source distribution:
Just like in the setup script, file and directory names in the manifest template should always be slash-separated; the Distutils will take care of converting them to the standard representation on your platform. That way, the manifest template is portable across operating systems.
