My cscope and ctags setup

Along with my .vimrc setup, I typically use cscope and ctags to navigate around a tree of source code.  I typically setup two bash scripts to separate searching from generation of the files.  This way,
I can generate the search files for a large source tree only if I have to.

The first file I make is the update.sh script:

>------------------------------------ Start of Contents ------------------------------------<

#!/bin/bash

#   Remove all existing files that we use to search
rm -rf *.files *.out tags

#   Build all the tags
ctags -R --c++-kinds=+p --fields=+iaS --extra=+q ../.

# find all files for cscope to process
find ../. -name "*.c" -o -name "*.cpp" -o -name "*.s" -o -name "*.h" > cscope.files

#   Generate lookup and reverse lookup databases

cscope -b -q -k

>------------------------------------ End of Contents ------------------------------------<

Then I make the search.sh script:

>------------------------------------ Start of Contents ------------------------------------<

#!/bin/bash

#   Tell Cscope to use gvim ( this will allow multiple files to be open )

export EDITOR=gvim

#   Search with the just built databases

cscope -d

>------------------------------------ End of Contents ------------------------------------<

I keep these scripts in their own directory in a source tree, and work from that directory.

The directory tree is set up like this:

These scripts are setup to go up one directory from cscope directory, and then recursively build a list of .c,.cpp,.s and .h files so that they can be used by cscope to build a lookup database file and a reverse lookup database file.  This speeds up the searching on larger code bases (like the one I use at work).  

Hopefully, this will help someone besides myself.  Have fun.

My vim / gvim config file

I finally took the time to recreate the .vimrc like I use to have a while ago.  I am posting it here so I don't lose it again, maybe you will find some of it useful.
