small case study

Hi! Just to share a small use I had of Moose. I am working on Roassal2. Roassal2 will be largely compatible with Roassal1. I am trying to make GraphET use Roassal2, and I need to know where Roassal is actually used by GraphET. Moose is ideal for this. I opened the moose panel, imported GraphET and type the following script in a Roassal easel opened on a class group: -=-=-=-=-=-=-=-=-=-=-=-= view shape rectangle if: #isStub fillColor: Color veryVeryLightGray; if: #isSUnitTestCase borderColor: Color green. view nodes: classGroup forEach: [ :cls | view shape rectangle if: [ :m | (m queryAllOutgoingAssociations atTypeScope select: [:c | c name beginsWith: 'RO' ] ) notEmpty ] fillColor: Color red; if: [ :m | (m queryAllOutgoingAssociations atTypeScope select: [:c | c name beginsWith: 'RT' ] ) notEmpty ] fillColor: Color blue. view interaction popupText: [ :m | ((m queryAllOutgoingAssociations atTypeScope select: [:c | c name beginsWith: 'RO' ]) inject: '' into: [ :s :e | s, ' ', e name ]), String cr, '-----', String cr, m sourceText ]; action: #inspect; on: ROMouseClick do: [:event | event model browseSource ]. view nodes: cls methods. view gridLayout. ]. view edgesFrom: #superclass. view treeLayout -=-=-=-=-=-=-=-=-=-=-=-= It gives a pictures as the following one:  large squares are classes link are inheritance: superclass is above its subclasses Inner squares are methods red square are methods of GraphET that reference to Roassal1 classes blue square are methods that have been migrated to Roassal2. Gray classes are stub classes A popup window details what is the reference. E.g.,  This is a popup I get by having the mouse above a method initialize. The reference to Roassal is because of the use of “ROElement”. I can click on the class to open a code browser on it. I can then modify the reference of ROElement to RTElement... Happy new year!

Excellent! That is exactly the spirit we should promote for developing in Pharo. I think this is an area where Moose can contribute greatly. We really have a shot at setting a new standard for how code should be developed. I will publish a longer blog post on the issue, but in the meantime, here is a quick reply. Actually, you do not need to load the whole project into a FAMIX model. You can do it simpler now directly with the Pharo objects.
Inspect this: (RPackageOrganizer default packageNamed: 'Graph-ET') allMethodReferences select: [ :each |
each method literalStrings anySatisfy: [ :literal | literal notNil and: [literal beginsWith: 'RO' ] ] ]
You get a simple list of RGMethodDefinitions that you can go through like you would do in a to do. The cool thing is that you can preview the source code in the inspector, and you can even modify the code right there. Essentially, you get a highly focused code browser (see attached).
 Of course, you can also create a visualization, if you want.
| view | view := ROMondrianViewBuilder new. view nodes: (RPackageOrganizer default packageNamed: 'Graph-ET') classes forEach: [:cls |
view shape rectangle if: [ :m | m method literalStrings anySatisfy: [ :literal |
literal notNil and: [literal beginsWith: 'RO' ]] ] fillColor: Color red. view nodes: ((cls methods select: [:m | m package name beginsWith: 'Graph-ET']) collect: #asRingDefinition).
view gridLayout ]. view edgesFrom: #superclass. view narrowTreeLayout. view If you inspect the view and click on a method, guess what :)
 There are things to improve here. One thing I would want is for the list of items to update when I am accepting the code. Another thing is that we should make Ring more concise. Nevertheless, it is already exciting. Don't you think so?
