NAME ^

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

VERSION ^

version 0.97

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If the coverage for the file being displayed is out of date the a fucntion called g:coverage_old() is called and passed the name of the file.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This configuration sets the background colour of the signs to a dark red when the coverage data is out of date.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 https://github.com/nyarly/Simplecov-Vim
