Hi,
I finally understand the issue (I have already beeng debugging this
in autumn).
STInST.RBParser parseExpression: '#(##(1/2))' -> error
This is because of:
(STInST.RBScanner on: '#(##(1/2))') next next -> $)
and this is because of...
scanLiteralArrayParts [
<category: 'private-scanning'>
currentCharacter == $# ifTrue: [^self scanLiteral].
...
scanLiteral [
<category: 'private-scanning'>
self step.
self stripSeparators.
...
currentCharacter == $# ifTrue: [^self scanExtendedLiterals].
scanExtendedLiterals [
<category: 'private-scanning numbers'>
| token |
self step.
currentCharacter == $(
ifTrue:
[self step.
^RBOptimizedToken start: tokenStart].
self scannerError: 'Expecting parentheses'
]
...
So scanExtendedLiterals will consume the $( of ##( but the $) of the literal
will
not be consumed leaving the extra token.
Now my question is if the optimized token should recursively scan the
literals? Or should the RBScanner count $( and $) to know that it needs
to read one more item?
