Re: Autoloading Cscope

Hi Jan, thanks for pointing this out.

So now (assuming there's no ctags-like one-liner trick for cscope) it comes down to the following:

------------------
function! LoadCscope()
    let db = findfile("cscope.out", ".;")
    if (!empty(db))
        let path = strpart(db, 0, match(db, "/cscope.out$"))
        set nocsverb " suppress 'duplicate connection' error
        exe "cs add " . db . " " . path
        set csverb   " switch back to verbose mode
    endif
endfunction
au BufEnter /* call LoadCscope()
------------------

I created a tip with the same code: http://vim.wikia.com/wiki/Autoloading_Cscope_Database, hope it'll be helpful for someone.

you can do the same thing with the findfile() function, see

 :h findfile()
