Generating Distutils MANIFEST file with hg manifest

[Martin Geisler]

Hello,

I have recently packaged my first Python project with Distutils, and
it worked well. But updating the MANIFEST.in file with new include
patterns when I add new directories to the repository seems silly, so
I have automated it.

The class below defines a new command which will use 'hg manifest' to
generate a preliminary list of files. The MANIFEST.in file is then
processed like normal to include/exclude more files.

  from distutils.command.sdist import sdist
  from distutils.core import setup
  
  class hg_sdist(sdist):
      def get_file_list(self):
          try:
              # Attempt the import here so that users can run the other
              # Distutils commands without needing Mercurial.
              from mercurial import hg
          except ImportError:
              from distutils.errors import DistutilsModuleError
              raise DistutilsModuleError("could not import mercurial")
  
          repo = hg.repository(None)
          changeset = repo.changectx()
          files = changeset.manifest().keys()
          
          # Add the files *before* the normal manifest magic is done.
          # That allows the manifest template to exclude some files
          # tracked by hg and to include others.
          self.filelist.extend(files)
          sdist.get_file_list(self)

The command can replace the normal sdist command like this:

  setup(cmdclass={'sdist': hg_sdist},
        ...
        )


I have no experience with Distutils, and have not played with the
Mercurial code before --- so I would like any feedback you have on
this method.

I noticed that Mercurial is packaged in a similar way where the
MANIFEST is created from 'hg manifest' and then doc/MANIFEST is added.
