git clone ssh://git.bobignou.red:23231/cscope_map_fork
This repository contains a fork of the script cscope_map.vim written by Jason Duell under a BSD 3-clause license.
The main modification I made was to let the script crawl from the working directory to the root directory to search for a cscope database. The default name for the database is cscope.out but you can supply any name with the $CSCOPE_DB environment variable.
I also inverted ctrl+\ and ctrl+<space> to better suit my need.
Furthermore, the key combination <C-@>r regenerates the cscope database and <C-@>R re-read it without modifying it.
