vim + cscope is insanely cool.

What's cscope?

cscope will generate a list of functions used in bitweaver and you can use a few keymaps to very quickly jump to those functions from within bitweaver (or any source code tree). cscope is faster and more feature rich than ctags.

Setting it up

1. Install cscope (via rpm, etc)
2. Add this file to /usr/local/bin/cscope-php

   
   #!/bin/bash
   
   for arg in "$@"
   do
           if [ -d $arg ]
           then
                   #echo Create list of php files in cscope.files
                   find $arg \( -name "*.php" -or -name "*.tpl" \) -and -not -regex "./temp/.*" -and -not -regex ".*/language.php" -print > $arg/cscope.files
                   #echo Create cscope database in cscope.out
                   cscope -b -i $arg/cscope.files -f$arg/cscope.out
                   rm -f $arg/cscope.files
           else
                   echo "Directory not found: $arg"
           fi
   done
   
   

3. Have a periodic crontab like:

   
   0 * * * * /usr/local/bin/cscope-php /path/to/project1 /other/path/to/project2
   
   

4. mkdir -p ~/.vim/plugin/ && curl -o ~/.vim/plugin/cscope_maps.vim http://cscope.sourceforge.net/cscope_maps.vim
5. Add the following to your ~/.vimrc (or /etc/vimrc for cool people)

   
   " Some scsope specific settings
   set cscopequickfix=s-,c-,d-,i-,t-,e-
   
   " always use cscope instead of tags
   set cst
   
   " path to cscope
   set csprg=/usr/bin/cscope
   
   " search databased before searching tag files
   set cscopetagorder=0
   
   " don\'t display cscope messages when adding database
   set nocsverb
   
   " add any database in current directory
   if filereadable("cscope.out")
   cs add cscope.out
   " else search up a few directories
   elseif filereadable("../cscope.out")
   cs add ../cscope.out
   elseif filereadable("../../cscope.out")
   cs add ../../cscope.out
   elseif filereadable("../../../cscope.out")
   cs add ../../../cscope.out
   elseif filereadable("../../../../cscope.out")
   cs add ../../../../cscope.out
   elseif filereadable("../../../../../cscope.out")
   cs add ../../../../../cscope.out
   " else add database pointed to by environment
   elseif \$CSCOPE_DB != ""
   cs add \$CSCOPE_DB
   endif
   
   " reset cscope verbosity
   set csverb
