I've also been a vim user for some time and consider myself decently proficient with it although I've done very little scripting with it. I have had cscope on my TODO list for a while and finally sat down today to figure it out. I think I'll find its functionality very useful in my day to day use of vim.

I mostly use cscope in relation with the Vim source.

The cscope database must be regenerated from time to time, or the
quickfix lists generated by :cscope find will get out of step with the code.

On Unix-like platforms, I recommend doing that after compiling Vim at
least once, so that auto-generated sources have been generated.

To build the database, I run the following command in the src/ source
directory:

cscope -bv ./*.[ch] ./*.cpp ./if_perl.xs auto/*.h auto/pathdef.c proto/*.pro


In Vim, I have the following "aids" in my vimrc for cscope (some of the
lines are quite long; I hope your mailer or mine won't mess them up):


if has('cscope')
set cst
if has('quickfix')
set csqf=s-,c-,d-,i-,t-,e-
endif
if version < 700
cnoreabbrev csa cs add
cnoreabbrev csf cs find
cnoreabbrev csk cs kill
cnoreabbrev css cs show
cnoreabbrev csh cs help
else
cnoreabbrev <expr> csa ((getcmdtype() == ':' && getcmdpos() <= 4)? 'cs
add' : 'csa')
cnoreabbrev <expr> csf ((getcmdtype() == ':' && getcmdpos() <= 4)? 'cs
find' : 'csf')
cnoreabbrev <expr> csk ((getcmdtype() == ':' && getcmdpos() <= 4)? 'cs
kill' : 'csk')
cnoreabbrev <expr> css ((getcmdtype() == ':' && getcmdpos() <= 4)? 'cs
show' : 'css')
cnoreabbrev <expr> csh ((getcmdtype() == ':' && getcmdpos() <= 4)? 'cs
help' : 'csh')
endif
command -bar Cscope cs add $VIMSRC/src/cscope.out $VIMSRC/src
set csverb
endif

where $VIMSRC has been defined earlier in my vimrc as the top-level
directory of my Vim repository clone (the parent of .hg, src, runtime, etc.)


Best regards,
