sys.path.insert(0, DEPOT_TOOLS_DIR)

Done.

[M-A Ruel, 2012/03/13 14:16:02]

Keep it grouped with system lib imports

Done.

+def GetBranches():

[M-A Ruel, 2012/03/13 14:16:02]

use PEP-8 style function naming, namely;

def get_branches():

[groby-ooo-7-16, 2012/03/14 20:39:51]

Done.

+  """Get list of all local git branches."""
+  result = []
+  for branch_name in git_cl.RunGit(["branch"]).split():

[M-A Ruel, 2012/03/13 14:16:02]

splitlines()

[groby-ooo-7-16, 2012/03/14 20:39:51]

Done.

+    if branch_name != '*':

[M-A Ruel, 2012/03/13 14:16:02]

Use branch_name[3:] instead

[groby-ooo-7-16, 2012/03/14 20:39:51]

Done.

+      result.append(Branch(branch_name))

[M-A Ruel, 2012/03/13 14:16:02]

So in the end, the function looks like this:

return [Branch(l[2:]) for l in git_cl.RunGit(["branch"]).splitlines()]
