S many thanks to the poster of that other message (soem days
ago) !
Here is now my question to the LaTeX gurus:
How can I define a LaTeX macro which gives me the END of the string
delivered by \input@path?
To give a concrete example: When I open document test-01.lyx with LyX in
the directory
/home/leo/leo/Tests/Lyx-Tests/Inputpath/blam
and compile my document it shows the correct path
/home/leo/leo/Tests/Lyx-Tests/Inputpath/blam/
Fine.
What I would like to derive from this string is
/.../Lyx-Tests/Inputpath/blam/ ;-)
See what I mean?
My LaTeX experience told me the need for \makeat...,
but this transformation I'm not able to do in LaTeX.
Any help appreciated
Cheers
Hellmut
kludge solution, if you know how deep your paths are:
\def\removeprefixx/#1/#2/#3/#4/#5{Your path is /.../#5}
\def\removeprefix#1{\expandafter\removeprefixx#1}
\removeprefix{\input@path}
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

Yes, but it involves magic. This post

describes how to split on commas and this one on spaces

Hellmut,
You might consider taking your question to a dedicated TeX channel.
Splitting on / is doable, escaping _ too, but the real hard part about
your request is this:
[-len:]
In tEx I do not know how to access the last N elements of a list when he
list length is unknown, although accessing the first N is easy. If you
know the list length then it's easy as well, but it looks not right for
your case because the path could be any depth.
Cheers,
Julien

OK, so this is getting a little off-topic, but the attached kind of
works, as you can see if you compile it. Unfortunately, it does not work
with macros, but only with a literal. I.e., this:
\split{hi/there/bob}
works but
\def\tempa{hi/there/bob}
\split{\tempa}
does not work. I do not see why, but perhaps someone else will know.

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

Yes, but it involves magic. This post
http://stackoverflow.com/questions/2402354/split-comma-separated-parameters-in-latex
describes how to split on commas and this one on spaces
http://tex.stackexchange.com/questions/12810/how-do-i-split-a-string
They can both be adapted.

Hi list,
I have to add one aspect to the functionality I'm looking for:
Since I'm used to use directory names which contain underscores ('_') my
python code should read:
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:]).replace('_','\_')
...
>>> shorten_path('/home/leo/leo/Test_01/abc',2)
'/.../Test\_01/abc'
>>>
TIA and Best regards

Hellmut,
You might consider taking your question to a dedicated TeX channel.
Splitting on / is doable, escaping _ too, but the real hard part about
your request is this:
[-len:]
In tEx I do not know how to access the last N elements of a list when he
list length is unknown, although accessing the first N is easy. If you
know the list length then it's easy as well, but it looks not right for
your case because the path could be any depth.
Cheers,
Julien

OK, so this is getting a little off-topic, but the attached kind of
works, as you can see if you compile it. Unfortunately, it does not work
with macros, but only with a literal. I.e., this:
\split{hi/there/bob}
works but
\def\tempa{hi/there/bob}
\split{\tempa}
does not work. I do not see why, but perhaps someone else will know.

\def\removeprefix#1{\expandafter\removeprefixx#1}
Can you explain the point of the \expandafter? I see this often, but
don't understand it.
rh
\expandafter\foo\bar tells TeX to expand \bar before expanding \foo
in this case:
first,
expand \input@path to /home/leo/leo/Tests/Lyx-Tests/Inputpath/blam
second,
parse /home/leo/leo/Tests/Lyx-Tests/Inputpath/blam using /#1/#2/#3/#4/#5
