hi I'm porting a distutils package to setuptools they have a Command that takes the po files and compiles them and then they are feeding a cmd Class to distutils, I read in the docs that the way of doing this in setuptools is with an entry point and that the entry point should be provided by a preinstalled package, the problem I see with that is that we'll need 2 packages to install one so is there a better way to do the following? from distutils.command.build import build as _build import msgfmt #this is the compiler class build_trans(cmd.Command): description = 'Compile .po files into .mo files' def initialize_options(self): pass def finalize_options(self): pass def run(self): po_dir = os.path.join(os.path.dirname(__file__), 'po') for path, names, filenames in os.walk(po_dir): for f in filenames: if f.endswith('.po'): lang = f[:len(f) - 3] src = os.path.join(path, f) dest_path = os.path.join('build', 'locale', lang, 'LC_MESSAGES') dest = os.path.join(dest_path, 'deluge.mo') if not os.path.exists(dest_path): os.makedirs(dest_path) if not os.path.exists(dest): print 'Compiling %s' % src msgfmt.make(src, dest) else: src_mtime = os.stat(src)[8] dest_mtime = os.stat(dest)[8] if src_mtime > dest_mtime: print 'Compiling %s' % src msgfmt.make(src, dest) class build(_build): sub_commands = _build.sub_commands + [('build_trans', None)] def run(self): _build.run(self) Also is there any setuptools enhancement to Extension, to handle C++ compilation and dependencies check?
