[Seaside] Code stats - Aida vs. Seaside vs. Iliad

[Janko Mivšek]

Dear Seasiders,

I made few measurements of code from three main Smalltalk web frameworks
and results are now available at Google
Docs:
https://spreadsheets.google.com/ccc?key=0Atnb1W9vuq9ndG4wbUpxNXpKQnFZRlFyQXpHclhZa2c&hl=en#gid=1

Here you'll find graphs of three distributions:

 - number of methods in classes
 - class inheritance depth
 - number of lines in methods

And also the following measurements:

  Code stats               Aida  Seaside  Iliad			
  ----------------------------------------------
  Nr of packages             1      74      9
  Nr of categories          14     123     26
  Nr of classes            145     943    265
  Nr of methods           4.465   8.758  2.368
  Lines of code          33.578  66.337  9.794
  Avg methods/class        31      9       9
  Avg lines/method        7,5     7,6     4,1

  Nr of test methods       67     914     412
  Avg tests/class         0,5      1      1,6

  % of commented methods  45%     23%      5%
  % of commented classes  32%     39%     13%

		
Code is loaded in Pharo with by Metacello configurations, tests are
included, all code included except Grease, Sport, Swazoo, Magritte.

Let me say few words about the reason I started those measurements:
mostly to find things to improve in Aida but I think results are
interesting more broadly. Specially, because they seems to reveal two
schools of thought about how to code in Smalltalk. Just compare the
number of packages, classes and methods per class, then first two graphs
about number of methods per class, and class inheritance depth.

Quite interesting results and quite some food for discussion!

Best regards
Janko
