Vim Flog Plugin

Personal version of fousa/vim-flog plugin.

Indicates the Flog number in front of the action in your Ruby code to indicate the complexity.

Requirements

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://github.com/fousa/vim-flog/raw/master/plugin/flog.vim -o ~/.vim/plugin/flog.vim

When this is done add :silent exe "g:flog_enable" to your .vimrc file.

To change colors of sings, use the higlight command. The used groups are

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 "let g:flog_high_limit=20"
