Vim Flog Plugin
(Forked from Ruby Cyclomatic Complexity Plugin created by @skammer)
Indicates the Flog number in front of the action in your Ruby code to indicate the complexity.
- flog rubygem
- vim 7.3+, compiled with:
First of all make sure you have a Vim installed with Ruby support. If you use MacVim than you can build your own version of Vim like this.
Here is an example of my configuration during the build:
./configure --with-features=huge --enable-rubyinterp --enable-pythoninterp --enable-perlinterp --enable-cscope
Install the Flog gem like this:
gem install flog.
To install the plugin just run this command in your Terminal:
curl https://raw.github.com/fousa/vim-flog/master/plugin/flog.vim -o ~/.vim/plugin/flog.vim
When this is done add
:silent exe "g:flog_enable" to your .vimrc file.
You can set the colors for the complexity indication with the following commands in your .vimrc:
Set the color of for low complexity:
:let g:flog_low_color_hl = "term=standout ctermfg=118 ctermbg=235 guifg=#999999 guibg=#323232"
Set the color of for medium complexity:
:let g:flog_medium_color_hl = "term=standout ctermfg=81 ctermbg=235 guifg=#66D9EF guibg=#323232"
Set the color of for high complexity:
:let g:flog_high_color_hl = "term=standout cterm=bold ctermfg=199 ctermbg=16 gui=bold guifg=#F92672 guibg=#232526"
Set the background color:
:let s:background_hl = "guifg=#999999 guibg=#323232 gui=NONE"
You can set the limits for the complexity indication with the following commands in your .vimrc:
Set the limit to switch to a medium complexity:
:silent exe "let g:flog_medium_limit=10"
Set the limit to switch to a high complexity:
:silent exe "
You can hide some levels of complexity:
Hide low complexity:
:silent exe "let g:flog_hide_low=1"
Hide medium complexity:
:silent exe "let g:flog_hide_medium=1"
You can also turn flog off and on:
Turn on flog
Turn off flog
Additionally, you can map this in your .vimrc:
:map ,f :call ToggleFlog()<cr>
