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.askdirectory 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:
'/c/windows'

Well, you could write it yourself....

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

Don't forget to convert backslashes into forward slashes.

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_cygpath(path):
drive, destination = path.replace('\\','/').split(':')
return '/cygdrive/' + drive.lower() + destination

Firstly, '/cygdrive' is overrated. Cygwin will accept: 'ls c:\\foo'
and 'ls c:/foo'


s= 'f:\\foo\\bar'

print re.sub(r'\\', '/', s)

m = re.match('^(.).*)$', s)
print '/cygdrive/' + m.group(1) + re.sub(r'\\', '/', m.group(2))

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