[Vim-latex-devel] new dir for bibliography?

[Mikolaj M. <mi...@wp...>]

Hello,

I have got request to make possible looking for bibliography in other
directory than directory of edited file.

The best solution is to use grep but it needs such combination:

		elseif exists("s:type") && s:type =~ 'cite'
			let grep_prg = &grepprg
			set grepprg=grep\ -Hrn\ --include='*.bib'\ $*\ /dev/null
			exe 'silent! grep! "@.*{'.s:prefix.'" '.s:search_directory 
			set grepprg=grep\ -Hrn\ --include='*.bbl'\ $*\ /dev/null
			exe 'silent! grepadd! "bibitem{'.s:prefix.'" '.s:search_directory
			set grepprg=grep\ -Hrn\ $*\ /dev/null
			exe 'silent! grepadd! "bibitem{'.s:prefix.'" %'
			let &grepprg = grep_prg
			call <SID>Tex_c_window_setup()

With changing value of &grepprg. Alas, I don't know how to make it
cross-platform. grep is easy to configure (GNU grep compatible grep tool
as requirement and variable in texrc) but what about /dev/null?
Without that lS doesn't work on terminal. Maybe something like that
(example line):

exe "set grepprg=".g:Tex_grepprg."\ -Hrn\ --include='*.bbl'\ $*".s:devnull

And at the beginning:
if has("unix") || has("mac_unix") || has("cygwin")
	let s:devnull = '\ /dev/null'
else
	let s:devnull = ''
endif

How such compbination would work on other than Linux systems?

m.

BTW, the use of quotes or double quotes may cause a problem with
&shellquote and &shellxquote.

Anyway, I have tried to set &grepprg by hand, but still, I'm not able to
use /usr/bin/grep (with your parameters) from my win32-vim + cygwin-bash
as shell. Actually, I think I have never been able to do so.
 [ grepprg == grep\ -Hrn\ --include='*.bib'\ $*  (± /dev/null)
 [ :grep '@.*{' /cygdrive/c/localtexmf/bibtex
 [ -> E303: Can not open the .swp file for 
 [    "/cygdrive/c/localtexmf/bibtex/ASTORIA/astoria.bib", retrieval
 [    impossible ... or something like that.
 [ with:
 [ shellquote = 
 [ shellxquote="
 [ shell      =c:\cygwin\bin\bash.exe
 [ shellredir =>%s 2>&1
 [ shellpipe  = 2>&1| tee
 [ shellslash = 1

The same command from bash works very well, and don't require I propose
/dev/null as the last argument.

Where is this function defined ?

If the grep program is "findstr", ie the default win32-vim (called from
the file-explorer or $COMSPEC), I doubt that -Hrn or --include will be
supported.
Some of its various useful options are:
    /n -> print line numbers
    /S -> recursion
    /R -> use regular expressions
    /M -> only the filename of the matching files
    /D:r,p -> search in a list of directories delimited by semi-comma.
           [it seems there is a little error in the doc at this point]

Personnally, I'd rather test &sh =~'sh'. I found it more accurate than
has('cygwin').
BTW, I have developped a little plugin aimed at easying the development
of portable plugins -- I still have the documentation to finish and some
tests to conduct. So far it seems quite functional.[1]

Impossible to make it work on my system (cygwin-bash + win32-vim). :-(
I don't know if it is due to an error of configuration on my side or
anything else.

Thanks for your reply. Knowing there is no sense to put effort in grep
issue I investigated how exactly LaTeX deals with bibliography files.

Results are encouraging. There can be only one \bibliography command in
file. It can be list of files with exact paths (no dealing with
TEXINPUTS) separated with commas. We have only to find \bibliography and
iterate through list and grep this files looking for bibkeys. This is
easy. If there is no \bibliography we will grep current directory looking
for *.bib and *.bbl files. No need for special variable. Also we should
check MainFile if there is \bibliography command. But should we check it
only if in current file this command doesn't exist? I think yes. But...
Ok small "algorithm"

Check if \bibliography exists in this file
Yes                    No        
Grep files from list   Grep files in directory  
                    \ /
                     Y
Grepadd current file for bibitem{
Check if in packages list is chapterbib
Yes
Check if current file is main file
Yes             No
END             Check if \bibliography exists in mainfile
                Yes                     No
                Grepadd files in list   Grepadd files in dir of mainfile

                          Grepadd mainfile for bibitem{

The only problem I see is with .bbl files mentioned by Srinath.
\include accepts only .tex files . In addition grepping *.bbl files (as
is now) will grep half-products of regular bib files. I will change 
grep 'bibitem{' *.bbl into
grep 'bibitem{ *.tex
Is it right?
Diagram above will change slightly but it is easy to imagine, I will not
draw it again.

Thanks again for your research.
