snippet to update local (bazaar, mercurial, svn) versioned source

[Alia Khouri]

Here's a very simple snippet I use to automatically keep my versioned
sources fresh.. Posted here in case it may be of use to anybody...

<code>
#!/usr/local/bin/python
import os, sys

src = '/Users/ak/Code/src'

# utility functions
join, isdir, listdir = os.path.join, os.path.isdir
def run(cmd):
    print cmd
    os.system(cmd)

ops = {
    '.bzr': ['bzr pull', 'bzr update'],
    '.hg': ['hg pull', 'hg update'],
    '.svn': ['svn update']
}

for folder in os.listdir(src):
    target = os.path.join(src,folder)
    if os.path.isdir(target):
        internal = os.listdir(target)
        for f in internal:
            if f in ops:
                print
                os.chdir(target)
                cmds = ops[f]
                print
                print target, '-->',
                for cmd in cmds:
                    run(cmd)
