how to auto load cscope.out in vim


I want to auto load my cscope.out in the subdirectory of my project, so I add this scripts in my .vimrc, which is as follows:

set cscopequickfix=s-,c-,d-,i-,t-,e-

if has("cscope")
    set csprg=/usr/bin/cscope
    set csto=1
    set cst
    set csverb
    set cspc=3
    "add any database in current dir
    if filereadable("cscope.out")
        cs add cscope.out
    "else search cscope.out elsewhere
    else
       let cscope_file=findfile("cscope.out", ".;")
        "echo cscope_file
        if !empty(cscope_file) && filereadable(cscope_file)
            exe "cs add" cscope_file
        endif      
     endif
endif

it works at first. But every time when I trying to do:

:cs find c [tag]  

The search result will appear in the QuickFix List, but the file which contains the result can not be opened.

Any advice would be appreciated.


Solution

  • If you add a cscope.out make sure it to set the correct path prefix. Otherwise it will show you the result but cannot load the file.

    example:

       cs add ../cscope.out ../
    

    so you should change your script to

     ...
     else
       let cscope_file=findfile("cscope.out", ".;")
       let cscope_pre=matchstr(cscope_file, ".*/")
       "echo cscope_file
       if !empty(cscope_file) && filereadable(cscope_file)
          exe "cs add" cscope_file cscope_pre
       endif
     ...
