Mercurial - How do I create a .zip of files changed between two revisions?

Question

I have a personal Mercurial repository tracking some changes I am working on. I\'d like to share these changes with a collaborator, however they don\'t have/can\'t get Mercuria

Answer 1

The best case scenario is to put the proper pressure on these folks to get Mercurial, but barring that, a patch is probably better than a zipped set of files, since the patch will track deletes and renames. If you still want a zip file, I've written a short script that makes a zip file:

import os, subprocess, sys
from zipfile import ZipFile, ZIP_DEFLATED

def main(revfrom, revto, destination, *args):
    root, err = getoutput("hg root")
    if "no Merurial repository" in err:
        print "This script must be run from within an Hg repository"
        return
    root = root.strip()

    filelist, _ = getoutput("hg status --rev %s:%s" % (revfrom, revto))
    paths = []

    for line in filelist.split('\n'):
        try:
            (status, path) = line.split(' ', 1)
        except ValueError:
            continue
        if status != 'D':
            paths.append(path)

    if len(paths) < 1:
        print "No changed files could be found."
        return

    z = ZipFile(destination, "w", ZIP_DEFLATED)
    os.chdir(root)
    for path in paths:
        z.write(path)
    z.close()

    print "Done."


def getoutput(cmd):
    p = subprocess.Popen(cmd.split(), stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    return p.communicate()


if __name__ == '__main__':
    main(*sys.argv[1:])

The usage would be nameofscript.py fromrevision torevision destination. E.g., nameofscript.py 45 51 c:\updates.zip

Sorry about the poor command line interface, but hey the script only took 25 minutes to write.

Note: this should be run from a working directory within a repository.
