In certain situations, we need to display metrics with meaningful labels in the browsers and in that case, showing selector names does not look good.

With proposed framework, we'll have the objects knowing their labels and know how to compute their units.

Hi,

Nice project.

You should probably take into consideration that FM3PropertyDescription is an object representing a property. For example:

   class := FAMIXClass new numberOfLinesOfCode: 42.

   loc := class mooseDescription allAttributes detect: [ :each | each name = #numberOfLinesOfCode ].

   class mmGetProperty: loc

   ==> 42

A possible route would be to add extra constraints (for example related to the type) to this object.

Another option would be to have the numberOfLinesOfCode method return a linesOfText unit. This implies that code like:

   group inject: 0 into: [:sum :each | sum + each numberOfLinesOfCode]

would break. We can live with this and fix the breaking places, but it should be a thing to consider.

Cheers,

Doru

Currently, there is no object in my knowledge to represent a metric in Moose. I would like to have this kind of object to ask it for example the name of the metric, a description, the associated selector...

Ideally this object should have the same behaviour than Unit framework; it should resolve units for example if you divide number of bugs by lines of code, you should get numberOfBugs.linesOfCode^(-1); then if you multiply this by line of code to get the estimated average value you get numberOfBugs...

If I missed an existing implementation close to this, thank you very much in advance to indicate me otherwise I will create a project for this and you are welcome to contribute.
