Flog reports the most tortured code in an easy to read pain report. The higher the score, the more pain the code is in.

• Easy to read reporting of complexity/pain.

• Uses path_expander, so you can use:

  • dir_arg – expand a directory automatically

  • @file_of_args – persist arguments in a file

  • -path_to_subtract – ignore intersecting subsets of files/directories

% ./bin/flog -g lib
Total Flog = 1097.2 (17.4 flog / method)

   323.8: Flog total
    85.3: Flog#output_details
    61.9: Flog#process_iter
    53.7: Flog#parse_options
