I tried to understand how to use cscope (with the Vim source as a set of
sources to apply it to). Bram, correct me if I'm wrong.
The following assumes $VIMSRC has been set (e.g. in the vimrc) to the
top-level directory of the Vim source & runtime distribution (on my
system, currently ~/.build/vim/vim72 )
- First of all, build the database (done once).
:new
:lcd $VIMSRC/src
:!cscope -bv ./*.[ch] ./perl.xs auto/*.h auto/pathdef.c
I have searched the src/Makefile for a target doing this kind of stuff
(the way the tags target builds a Vim tagfile for the same source) but
have failed.
It's not clear to me whether to repeat this after the sources change,
I'll have to read the cscope manpage in more detail (it seems to say
cscope is clever enough to update the database if the sources have
changed, but can I rely on that?)
BTW, here "cscope --version" anwsers:
cscope: version 15.6
- Once per session (done manually when starting to use it). First two
lines are of course not needed if already done by building the database
as shown above. Last line (setting 'cscopequickfix') can be in vimrc. It
is of course the "useful setting" given at ":help csqf" with no quotes
(also no single quotes around 'csqf').
:new
:lcd $VIMSRC/src
:cs add cscope.out
" use quickfix for most common queries
:set csqf=s-,c-,d-,i-,t-,e-
- Find where a symbol is defined (with an example from a recent vim_dev
thread)
:cs find g TBUFSZ
- Find where symbol is used (using the same symbol)
:cs find s TBUFSZ
etc.
Best regards,
Tony.
