Hi list,
recently in another post I found the internal LaTeX macro
\input@path
mentioned. Putting this (surrounded by \makeatletter and \makeatother)
in an ERT eventually gives me the correct path to my LyX document as
string in the document.
Soooooooo 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 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
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.
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.
