Coming out

It is time I come right out and say it...

It is true. I like to hurt code. With code I like to hurt systems. It is something I'm good at, I just haven't been able to put it into words very well. Potential employers don't quite understand or empathize when you talk about hurting code, even tho that might be exactly what they're trying to hire you for. They just don't think of it in those terms. To help gather my thoughts, tools, and to communicate my goals more clearly, I've launched ruby.sadi.st. Enjoy...

Flogging the World

Flog 1.1 is out, and with it a lot of enhancements to pointing out code complexity. In particular, it adds full ABC (Assignment, Branches, and Calls) metrics. ABC is a nice, simple whitespace independent way of measuring code that I talked about it in my RubyConf 2005 talk.

Well... I went overboard (again). I flogged every (latest) gem released and poked around. I won't release the full report yet, but here is a bit of a peek:

Statistics:

total # gems      :    1766
total # methods   :  134839
avg methods / gem :   76.35 +/-  170.66
avg flog / project: 1245.47 +/- 3416.56
avg flog / method :   14.06 +/-   32.60

Top 10 Methods per Gem:

 1:       fxruby-1.6.11.gem: 2559 methods,  4.71 +/- 11.33 flog
 2:           bio-1.1.0.gem: 2286 methods, 13.10 +/- 23.22 flog
 3:       puppet-0.23.2.gem: 2044 methods, 15.85 +/- 22.54 flog
 4:       facets-1.8.54.gem: 1962 methods, 11.42 +/- 28.21 flog
 5:        soap4r-1.5.7.gem: 1452 methods, 11.55 +/- 16.59 flog
 6:       bioruby-0.6.4.gem: 1450 methods, 12.04 +/- 22.36 flog
 7:         deplate-0.8.gem: 1426 methods, 14.35 +/- 25.47 flog
 8:           rio-0.4.1.gem: 1291 methods,  6.44 +/- 10.17 flog
 9: activerecord-1.15.3.gem: 1279 methods, 15.12 +/- 26.89 flog
10:   actionpack-1.13.3.gem: 1129 methods, 12.61 +/- 19.95 flog

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

% ./bin/flog bin/flog
Total score = 128.7

Flog#report: (21)
     4: puts
     2: sort_by
...

Changes:

• 3 major enhancements:
  • Added assignments and branches and a lot of other stuff. rad.
  • Added process_iter section for DSL style blocks (rake tasks etc).
  • Made Flog usable as a library.
• 12 minor enhancements:
  • Added -a flag to turn off threshold culling for other tools.
  • Added -s for summarizing the score.
  • Added -v feedback to know what file you're flogging.
  • Added branching penalty so tons of nested conditionals get beat down.
  • Added send (3).
  • Capture and ignore SyntaxErrors from template/generator code. Stupid DHH.
  • Report can now take an IO object.
  • blockargs now penalizes all non-benign forms of blockpass.
  • Added usage to bin/flog. Moved -I processing to bin/flog.
  • Added unpack.rb and updatescores.rb at base level (not installed)
  • Added scoring for blockpass.
  • Converted totals to use distance formula on ABC's.

• 3 bug fixes:

  • Ran flog on every latest gem available. Found a bunch of problems.
  • Use a stack for both class/module and method accounting.
  • block_args weren't processing the arg

4:44 : Chad: All heckling was thwarted! YAY!!!
4:44 : Chad: my sissy unit tests aren't so sissy after all ;)
4:47 : Ryan: or that means that your code is so tightly
             coupled that it all falls apart whenever you
             change anything
4:47 : Chad: ass hat
