how to resolve Windows pathnames into cygwin ones

[mgierdal]

I am looking for a function to resolve 'F:/foo/bar' into '/cygdrive/f/
foo/bar'. I get the original dirpath from tkFileDialog.as kdirectory in
a Windows form and none of os.path.* functions seem to resolve it to a
cygwin form. Rather they _append_ it to the current directory,
resulting at best in a monster '/cygdrive/c/whatever/f/foo/bar'.
It's all being developed under cygwin currently (so it is a kind of
mixed environment), but I would like the fix to work correctly in any
environment.

Thanks,
Marcin

You can call the cygpath utility:

>>import commands
commands.geto utput("cygpath c:/windows")

'/c/windows'

Well, you could write it yourself....

(assuming path is a string, here's a first go at it...)
def path_into_cygpa th(path):
drive, destination = path.split(':')
newpath = '/cygdrive/' + drive.lower() + destination
return newpath

Don't forget to convert backslashes into forward slashes.

Whoops.

Here we go then (are forward slashes valid in a filename in windows?)
def path_into_cygpa th(path):
drive, destination = path.replace('\ \','/').split(':')
return '/cygdrive/' + drive.lower() + destination

Well yes, I was hoping for a library function, but none provides it.
Thanks for the code. Works nicely.
