Ruby Cyclomatic Complexity Plugin

rubycomplexity.vim plugin computes how complex your methods are using Flog magic and neatly displays it to you in the signs column next to your code.

Requirements

• ruby
• flog rubygem
• vim 7.2+, compiled with:
  • +ruby
  • +signs

Configuration

g:rubycomplexity_enable_at_startup

Turn automatic plugin loading on and off. Set it to 0 if you do not want to call ShowComplexity() on every read or write of *.rb file

Colors:

g:rubycomplexity_color_low

Sets color for low compelxity signs. Default value is "#004400".

g:rubycomplexity_color_medium

Sets color for medium complexity signs. Default value is "#bbbb00".

g:rubycomplexity_color_high

Sets color for high complexity signs. Default value is "#ff2222".

Ranges:

g:rubycomplexity_medium_limit

Sets medium complexity limit. Default value is 7.

g:rubycomplexity_high_limit

Sets high complexity limit. Default value is 14.
