Hi Julien,
thanks for your answer ;-)
I think I got the basic idea
BUT i Do NOT know the length the path delivered by \input@path.
To make clear what I'm looking for I put it in python code:
leo@sylhepta ~ $ python
Python 2.6.6 (r266:84292, Sep 15 2010, 15:52:39)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> def shorten_path(path, len):
... return '/.../' + '/'.join(path.split('/')[-len:])
...
>>> shorten_path('/home/leo/leo/Test/abc',2)
'/.../Test/abc'
>>>
Can this be done in (La)TeX?
Thanks again and thanks to all others who contributed
Best regards
Hellmut
