Hi,
One result of Friday���s Pharo Sprint in Chile: Use the nice icons of the new text editor
to display some of the semantic errors nicely (instead of breaking flow with a intrusive dialog):
This was done by Johan based on the prototype Miguel did in September:
1) unused temps:
<unused.png>
(the ���drag the crosshair���r is an artefact of the snapshot tool)
2) temps used that are not initialised:
<uninit.png>
In a next step, we need to integrate that with the QA tool��� no need to have this reported
twice.
What is nice is that this simplified the Compiler: instead of having an Exception and raising
it, we now just annotate the AST:
unusedVariable: variableNode
variableNode propertyAt: #semanticWarning put: 'unused variable���
(this is very simple for now, with a node just being able to have one kind of semanticWarning).
SemanticWarningIconStyler is what adds the icon. It has 4 methods with one line each.
