I saw that
selectionIntervalFor:
uses
selectionParseTreeIntervalFor: aString
| parseTree answerBlock |
parseTree := RBParser
parseMethod: aString
onError: [ :str :pos | ^ nil ].
answerBlock := [ :aNode :answer | ^ aNode sourceInterval ].
self searchStrings do: [ :each |
| matcher tree |
matcher := RBParseTreeSearcher new.
matcher matchesTree: (RBLiteralNode value: each) do:
answerBlock.
each isSymbol
ifTrue: [
tree := RBParseTreeSearcher buildSelectorTree:
each.
tree notNil ifTrue: [ matcher matchesTree: tree
do: answerBlock ] ]
ifFalse: [
tree := RBVariableNode named: each.
matcher
matchesTree: tree do: answerBlock;
matchesArgumentTree: tree do:
answerBlock ].
matcher executeTree: parseTree ].
^ nil
and I was wondering where is used the selectionIntervalFor:
Then I saw that BrowserEnvironmentWrapper introduces environment (which is good)
Now the superclass uses directly Smalltalk globals so may be this would be good
to move enviroment above
this way we can have a selection of the environemt as in BrowserEnvironment and
also have a browser that can browse a remote
environment.
