Re: Cross referencing in VIM

Sorry I bring this up again.

My difficulty is with installing cscope and getting it to run.

Per the documentation, I have added this line into cscope_maps.vim:

 if filereadable("cscope.out")
        cs add cscope.out 

...

and to _vimrc, I added:

if has('cscope')
" set cscopetag cscopeverbose
...

then, every time I attempt to open a file in Vim, I get following error message: 

"Error detected while processing C:\Program Files\Vim\vim73\plugin\cscope_maps.vim:
line   42:
E262: error reading cscope connection 0"

I looked for a solution with no luck.

Anyone knows how to fix this and better yet how to get cscope in Vim running?

Thanks for any help.

I used to use CScope a lot. I did not find it hard to use or understand in
the slightest. I found Vim's built-in documentation (:help cscope) to be all
I really needed, plus web searches for scope for setting up the databases in
the first place. With cscope, I also used the CCTree plugin to view an
entire call tree for any given function:

  http://www.vim.org/scripts/script.php?script_id=2368

I've since mostly stopped using CScope, because I've started using Eclim.
Eclim integrates Vim with Eclipse allowing you to use Eclipse's extensive
code navigation and information features, including:

• search for all references (e.g. function calls) for the item under the
  cursor, similar to :cscope find s
• seacrh for the declaration of an item, similar to :cscope find g
• search for the definition of an item :cscope find g
• show the entire call tree leading to a function, similar to CCTree +
  cscope.
• start a vimgrep relative to the project root, similar to :cscope find t or
  :cscope find e
• fuzzy find of files within the project, similar to :cscope find f

It can do much more (like insert-mode completion) but the above is all I
used cscope for, and Eclim does it better.

  http://eclim.org/features.html

Note that there is not (that I have found) an equivalent to :cscope find d
or :cscope find i, but I used these very rarely, if at all. Nor does Eclim
currently support call trees of functions *called by* the given function,
although Eclipse does, so that may come in the future.
