Re: [Pharo-project] [Pharo-users] SLOC in Smalltalk
Hi Janko. Thanks for your useful package. Apparently there is some issue with #linesOfCode. The dummy expression below return 5 instead of 4 in Pharo 1.4 and 2 because is counting the autogenerated 'DoIt' selector. (UndefinedObject evaluatorClass new compileNoPattern: '| oc | oc := OrderedCollection new: 20. oc add: 1. oc size' in: UndefinedObject context: nil notifying: nil ifFail: []) generate linesOfCode Hernán El 31/03/2013 10:17, Janko Mivšek escribió:
Hi Hernán
I once did some code statistics for our web frameworks, by counting:
- Nr of packages, categories, classes, methods - lines of code - Avg methods/class - Avg lines/method
- Nr of test methods - Avg tests/class
- % of commented methods - % of commented classes
Then three graphs were drawn:
- Methods in classes - Class inheritance depth - Lines in methods
Results can be seen here:

The code measuring all above is here:

Hope this helps Janko

Hi there, Guys, what are you using to measure logical lines of code (LOC) in Pharo? Given I am measuring a script, is there any other software measure you may recommend? Cheers,
Hernán
Hernán, It would be nice if you patch the WebCodeStats by yourself. I just set a read-write access to the http://www.squeaksource.com/WebCodeStats.html. Best regards Janko Dne 02. 04. 2013 04:54, piše Hernán Morales Durand:

Janko, As far as I can see the CompiledMethod>>linesOfCode belongs to Kernel-System of Pharo. I think it would be better to have it patched in the system if people agrees. Maybe can I have access to report a bug/issue? Cheers, Hernán El 02/04/2013 4:52, Janko Mivšek escribió:

Hello, I do not think that this is wrong. The doit *does* contain a selector. if #linesOfCode would contain a special case for doits, it would be inconsistent. E.g. print this: thisContext method sourceCode --> 'DoIt ^ thisContext method sourceCode' There is a Doit. There is even a return in the that is generated⦠and the doit is actually pretty-printed: thisContext method linesOfCode --> 2 So in short: dots are special, there is no need to change #linesOfCode, as there is no thinkable change that would make any sense. In general, LOC as a metric is not that good. It is better than nothing, but it makes more sense to count e.g. message sends or use more advanced metrics on the AST (not every statement adds the same to complexity, e.g. conditionals versus simple statements).
