Devel::Cover::Report::Vim - Backend for displaying coverage data in Vim
cover -report vim
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
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If the coverage for the file being displayed is out of date the a function called CoverageOld() is called and passed the name of the file. Similarly, for current coverage data file CoverageValid 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 commands 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! CoverageValid(filename) call s:set_bg(s:bg_valid) endfunction function! CoverageOld(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This configuration sets the background colour of the signs to a dark red when the coverage data is out of date.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
