[Pharo-users] Integrating a custom spotter, reusing current code

[Stephan Eggermont]

In the CodePanel demo, I now managed to add some spotter integration
by copy-pasting some code from GTSpotter and adding actLogic.
Object subclass: #CardSpotterModel
        instanceVariableNames: 'panel'
        classVariableNames: ''
        category: 'NewUI'

CardSpotterModel>>spotterImplementorsFor: aStep
        <spotterOrder: 10>
        aStep listProcessor
                title: 'Implementors';
                filter: GTFilterImplementor item: [ :filter :context |
			SystemNavigation default allBehaviorsDo: [ :class | class methodsDo: 
filter ] ];
                wantsToDisplayOnEmptyQuery: false;
                actLogic: [:item :step | step exit. panel newCardFor: item]

That is used
CodeCard>>spotImplementers
        |model|
        model := CardSpotterModel on: self panel.
        
        GTSpotterMorph new
                extent: 400@500;
                doLayout;
                spotterModel: (GTSpotter on: model);
                openCenteredInWorld.

That is ugly, as it is a duplication. Also, how do I get to a list
of the implementers/senders/references/etc of the method/class?
What is the improved and approved way to do this :) ?
