Hi
for certain metrics we need to compute the total amount of lines of code for the complete
project.
FAMIXClass >> calculateARLCOMUnderstand
"Class LCOM LOC
C1 12 1000
C2 2 50
For C1 1000/1050 * 12
For C2 50/1050 * 2
"
self halt.
^ self TR_LoC / self mooseModel TR_totalNumberOfLinesOfCode * self TR_LCOM
Now I have a question because totalNumberOfLinesOfCode does exist on Model but on
TypeGroup
I wrote it like that on FAMIXTypeGroup
TR_totalNumberOfLinesOfCode
<MSEProperty: #TR_totalNumberOfLinesOfCode type: #Number>
<derived>
<MSEComment: 'Total number of lines of code from Understand'>
^ self
lookUpPropertyNamed: #TR_totalNumberOfLinesOfCode
computedAs: [ (self sumNumbers: [ :each | each TR_LoC ]) asFloat ]
How can I access for example totalNumberOfLinesOfCode at the model level?

Hi,
The way I see it you need to compute a metric in a class that depends on the context of
all classes in the system.
I would implement it like this:
FAMIXClass >> calculateARLCOMUnderstand
"Class LCOM LOC
C1 12 1000
C2 2 50
For C1 1000/1050 * 12
For C2 50/1050 * 2
"
self halt.
^ self TR_LoC / self mooseModel allModelClasses TR_totalNumberOfLinesOfCode * self
TR_LCOM
Cheers,
Doru

Tx you guys for the answers!!
I cannot reply directly
Now we found a crazy in Pharo. Believe or not
And I’m curious if you can reproduce it
We wrote this method in FamixClass
FAMIXClass >> TR_LCOM
<MSEProperty: #TR_LCOM type: #Number>
<MSEComment: 'lack of cohesion in methods from Understand'>
<derived>
^ self propertyNamed: #TR_LCOM
And since it is about Understand metrics
FAMIXClass >> Und_LCOM
<MSEProperty: #Und_LCOM type: #Number>
<MSEComment: 'lack of cohesion in methods from Understand'>
<derived>
^ self propertyNamed: #Und_LCOM
And this looks forever….. when we use Und_ :)
Crazy no.

So when you prefix your selector with Und_, it takes forever to get
executed?
I tried it on Pharo 6.1 64 bits (Ubuntu) i.e. created a class and a
selector with Und_ prefix.
And I could not reproduce the behavior/problem.
I didn't try it in moose though because I couldn't make Pharo 32-bit work
on Linux 64-bit.
Crazy no.

Me too. this is super super strange.
probably a compilation problem.

We had
the problem at Synectique and it is a complex issue
(and no, we did not find a satisfactory solution)
For LOC specifically, in Smalltalk your solution can work, but not in
Java, since classes and methods can contain inner/anonymous classes and
you don't want to count them twice
The problem also exist in Ada (not with classes)
Second, there is also the larger problem of aggregation of a metric at
some higher abstraction level
- some times you want to sum (e.g. LOC) ;
- sometimes it seems more reasonable to average (e.g. cyclomatic
complexity at the level of classes) ;
- sometimes you want to recompute (e.g. coupling between 2 classes can
often not be aggregated from the results of couplings between their
methods) ;
- and also averaging is not always a good solution in itself and you
want something more sophisticated (http://dx.doi.org/10.1002/smr.1558)

SourceLanguage object can't manage this info?
I think we already discussed it in the context of C/CPP (Modules vs. Class)
and this is how we started to manage variations amongst these two.
Ideally, one would want to create several metrics computation strategies so
that these can be shared amongst languages.
