[Cuis-dev] Debug leads a locked UI

[Hernán Wilkinson]

Hi Hilaire,
 as I said, I had the same issues and as Juan mentioned there are problems
with quick returns (when you have just 1 for example) or with empty lines.
 I'm attaching the change you have to make to fix it.
 The code should be:

debugSketch
codeView editor lineSelectAndEmptyCheck: [^self].
self stopSketch.
self isDocVisible ifTrue: [self toggleHelp].
codeView scroller acceptContents.
codeView editor
afterCompiling: model
do:  [ :compiler :method :receiver :context | (method notNil and: [method
isQuick not]) ifTrue: [
debugger _ Debugger
openMinimalDebugging: [
method
valueWithReceiver: receiver
arguments: (context ifNil: [ #() ] ifNotNil: [ { context } ])]
to: method.
debugger layoutMorph borderWidth: 1.
codeAndViewPanel replaceSubmorph: codeView by: debugger layoutMorph.
debugger model when: #closeViews send: #stopDebbuger to: self.
debugger contextVariableInspector selectionIndex: 3.]
]
ifFail: [].

Cheers!
Hernan
