[SOLVED] use regex vim with tagbar to get filename of graphic in latex

use regex vim with tagbar to get filename of graphic in latex

I'm using vim and tagbar to write my latex files. In the latex source, the input for a graphic look like this:

\includegraphics[width=0.70\textwidth]{../../figures/mechanical_diffusion/plate_hole/plate_hole_fem_elas_cd_map}

I would like to get in tagbar only the filename, in this case, "plate_hole_fem_elas_cd_map". I created a .ctags in my home, which has the following line (modified from the original line found in tagbar documentation):

--regex-latex=/^[\t]*\\includegraphics[[:space:]]*(\[[^]]*\])?[[:space:]]*(\[[^]]*\])?[[:space:]]*\{[\.{2}\/]*[[a-zA-Z0-9_]+\/]*([^}]+)\}/\3/g,graphic+listing/

But I cannot get only the file name. I tried other things, but sometimes I only remove the "../", sometimes I get only "plate_hole".. What did I do wrong ?

Thanks

Solution

Your regular expression is incorrect, you can't use character classes like that. This one worked for me:

--regex-latex=/^[\t]*\\includegraphics[[:space:]]*(\[[^]]*\])?[[:space:]]*(\[[^]]*\])?[[:space:]]*\{([^}]+\/)?([^}\/]+)\}/\4/g,graphic+listing/
