SYNOPSIS

12        cover -report vim
13

DESCRIPTION

15       This module provides a reporting mechanism for displaying coverage data
16       in Vim.  It is designed to be called from the "cover" program.
17
18       By default, the output of this report is a file named "coverage.vim" in
19       the directory of the coverage database.  To use it, run
20
21        :so cover_db/coverage.vim
22
23       and you should see signs in the left column indicating the coverage
24       status of that line.
25
26       The signs are as follows:
27
28        P - Pod coverage
29        S - Statement coverage
30        R - Subroutine coverage
31        B - Branch coverage
32        C - Condition coverage
33
34       The last of the criteria, in the order given above, is the one which is
35       displayed.  Correctly covered criteria are shown in green.  Incorrectly
36       covered criteria are shown in red.  Any incorrectly covered criterion
37       will override a correctly covered criterion.
38
39       If the coverage for the file being displayed is out of date the a
40       function called CoverageOld() is called and passed the name of the
41       file.  Similarly, for current coverage data file CoverageValid is
42       called.
43
44       Signs may be overridden in a file named devel-cover.vim located
45       somewhere underneath the ~/.vim directory.
46
47       For example, I use the solarized theme and keep the following commands
48       in my local configuration file ~/.vim/local/devel-cover.vim:
49
50        let s:fg_cover = "#859900"
51        let s:fg_error = "#dc322f"
52        let s:bg_valid = "#073642"
53        let s:bg_old   = "#342a2a"
54
55        let s:types = [ "pod", "subroutine", "statement", "branch", "condition", ]
56
57        for s:type in s:types
58            exe "highlight cov_" . s:type .       " ctermbg=1 cterm=bold gui=NONE guifg=" . s:fg_cover
59            exe "highlight cov_" . s:type . "_error ctermbg=1 cterm=bold gui=NONE guifg=" . s:fg_error
60        endfor
61        exe "highlight SignColumn ctermbg=0 guibg=" . s:bg_valid
62
63        " highlight cov ctermbg=8 guibg=#002b36
64        " highlight err ctermbg=0 guibg=#073642
65
66        function! s:set_bg(bg)
67            for s:type in s:types
68                exe "highlight cov_" . s:type .       " guibg=" . a:bg
69                exe "highlight cov_" . s:type . "_error guibg=" . a:bg
70            endfor
71            exe "highlight SignColumn ctermbg=0 guibg=" . a:bg
72        endfunction
73
74        function! CoverageValid(filename)
75            call s:set_bg(s:bg_valid)
76        endfunction
77
78        function! CoverageOld(filename)
79            call s:set_bg(s:bg_old)
80        endfunction
81
82       This configuration sets the background colour of the signs to a dark
83       red when the coverage data is out of date.
84
85       coverage.vim adds two user commands: :Cov and :Uncov which can be used
86       to toggle the state of coverage signs.
87
88       The idea and the vim template is shamelessly stolen from Simplecov-Vim.
