https://github.com/mvidner/call-graph # Call Graph This makes a call graph among methods of a single Ruby file. I made it to help me orient myself in unfamiliar legacy code and to help identify cohesive parts that could be split out. Yes, it is quick and dirty. ## Requirements - [parser gem](https://github.com/whitequark/parser) - [Graphviz](http://www.graphviz.org/) ## License MIT ## Example [One file in YaST][p-rb] has around 2700 lines and 73 methods. The call graph below was made with ```console $ ./call-graph ../yast/packager/src/modules/Packages.rb $ dot -Tpng -oPackages.png ../yast/packager/src/modules/Packages.dot ``` If the resulting size is too big, use ImageMagick: ```console $ convert Packages.png -resize 1200 Packages-small.png ``` [p-rb]: https://github.com/yast/yast-packager/blob/a0b38c046e6e4086a986047d0d7cd5d15...  -- Martin Vidner, YaST Team http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu
