Hm,
as I just commented off-list to someone else, I guess what I'm really missing
is something like:
import find
for file in find("/var/trac",iname="trac.ini"):
~ with open(file, 'a') as f:
~ f.writelines(["[inherit]", "blah=something"])
(or. better yet, a nice "appendline()/appendlines()"-convenience method on all
file objects that allows for doing the same thing (ie equivalent to the shell
">>" operator):
for file in find("/var/trac",iname="trac.ini"):
~ file.appendlines(["[inherit]", "blah=something"])
But I suppoose the "meme" i was missing was glob and/or os.walk. So coding
"around" the "lack" of a find module:
import os
for root, files, dirs in os.walk("/var/trac"):
~ for file in files:
~ if file.lower() == "trac.ini":
~ with open(os.path.join(root,file), "a") as f:
~ f.writelines(["[inherit]", "blah=something"])
I suppose I can live with glob and os.walk -- but it's a bit painful that
os.walk returns only names as strings, and that there are no "reasonable"
file/path objects (note the main reason that this is necessary is of course the
fact that not all os' agree on path separators and/or
mountpoints/"driveletters").
Still a python find-module seems like a good (and pretty simple) idea.
