How do you enable syntax? Are you setting it on manually? Or do you have a "syntax on" somewhere in your _vimrc? > Here are the details behind my attempt at using autocommand and > ~/vimfiles/after/syntax/tex.vim. > > 1 ~/vimfiles/after/syntax/tex.vim > 2 ------------------------------- > 3 setg isk+=_ > 4 setlocal isk+=_ > 5 This should have worked. Can you check with :scriptnames whether this file actually gets sourced? Hod did you determine the ~ directory? Maybe Vim is looking in a place you didn't expect for $HOME. > 6 ~/.vim/after/syntax/tex.vim > 7 --------------------------- > 8 setg isk+=_ > 9 setlocal isk+=_ > 10 This should work on Unix-like systems but not on Windows, IIUC. > 11 ~/_vimrc > 12 -------- > 13 autocmd BufNewFile,BufRead,BufWinEnter *.tex setl isk+=_ | setg isk+=_ > 14 autocmd BufNewFile,BufRead,BufWinEnter *.bib setg isk+=_ | setl isk+=_ > 15 filetype on > 16 au Syntax * setl isk+=_ > Line 16 should work, at least if "syntax on" is set somewhere above. You should actually be able to be more selective, with "au Syntax tex setl isk+=_" instead of matching ALL syntaxes. > I bastardized lines 13-14 from code higher up in the _vimrc, not sure if it > is kosher. > They look fine to me, and the BufWinEnter should even take care of overriding any modelines. In summary: you are using 3 methods simultaneously that each ought to be working if the files are actually being sourced. Double-check that these files are being sourced using :scriptnames. If the files do actually show up, try the :verbose set isk? command again. Maybe you can find a specific problematic line. -- -- You received this message from the "vim_use" maillist.
