NAME
       Devel::Cover::Report::Vim - Backend for displaying coverage data in Vim

VERSION
       version 1.03

SYNOPSIS
	cover -report vim

DESCRIPTION
       This module provides a reporting mechanism for displaying coverage data in Vim.	It is
       designed to be called from the "cover" program.

       By default, the output of this report is a file named "coverage.vim" in the directory of
       the coverage database.  To use it, run

	:so cover_db/coverage.vim

       and you should see signs in the left column indicating the coverage status of that line.

       The signs are as follows:

	P - Pod coverage
	S - Statement coverage
	R - Subroutine coverage
	B - Branch coverage
	C - Condition coverage

       The last of the criteria, in the order given above, is the one which is displayed.
       Correctly covered criteria are shown in green.  Incorrectly covered criteria are shown in
       red.  Any incorrectly covered criterion will override a correctly covered criterion.

       If the coverage for the file being displayed is out of date the a fucntion called
       g:coverage_old() is called and passed the name of the file.  Similarly, for current
       coverage data file file g:coverage_valid is called.

       Signs may be overridden in a file named devel-cover.vim located somewhere underneath the
       ~/.vim directory.

       For example, I use the solarized theme and keep the following comamnds in my local
       configuration file ~/.vim/local/devel-cover.vim:

	let s:fg_cover = "#859900"
	let s:fg_error = "#dc322f"
	let s:bg_valid = "#073642"
	let s:bg_old   = "#342a2a"

	let s:types = [ "pod", "subroutine", "statement", "branch", "condition", ]

	for s:type in s:types
	    exe "highlight cov_" . s:type .	  " ctermbg=1 cterm=bold gui=NONE guifg=" . s:fg_cover
	    exe "highlight cov_" . s:type . "_error ctermbg=1 cterm=bold gui=NONE guifg=" . s:fg_error
	endfor
	exe "highlight SignColumn ctermbg=0 guibg=" . s:bg_valid

	" highlight cov ctermbg=8 guibg=#002b36
	" highlight err ctermbg=0 guibg=#073642

	function! s:set_bg(bg)
	    for s:type in s:types
		exe "highlight cov_" . s:type .       " guibg=" . a:bg
		exe "highlight cov_" . s:type . "_error guibg=" . a:bg
	    endfor
	    exe "highlight SignColumn ctermbg=0 guibg=" . a:bg
	endfunction

	function! g:coverage_valid(filename)
	    call s:set_bg(s:bg_valid)
	endfunction

	function! g:coverage_old(filename)
	    call s:set_bg(s:bg_old)
	endfunction

       This configuration sets the background colour of the signs to a dark red when the coverage
       data is out of date.

       coverage.vim adds two user commands: :Cov and :Uncov which can be used to toggle the state
       of coverage signs.

       The idea and the vim template is shamelessly stolen from Simplecov-Vim.	See
