Henri Biestro commented on JEXL-85:
-----------------------------------
URL: http://svn.apache.org/viewvc?rev=809099&view=rev
Log:
added Unicode escape sequence to String literal handling; fixed non-escapable
character handling; added $ as escapable character in UnifiedJEXL

commons/proper/jexl/branches/2.0/src/test/java/org/apache/commons/jexl/UnifiedJEXLTest.java
URL: http://svn.apache.org/viewvc?rev=809160&view=rev
Log:
*Parser.jjt*: modified grammar to make last statement terminator (aka ';')
optional.
This implied a change in AdditiveOperation and the introduction of
AdditiveOperator to break conflicts.
*Interpreter.java*: modified according to grammar ({Add,Subtract}Node replaced
by AdditiveNode.
Debugger.java: made debugger expression-AST roundtrip enabled; the Debugger can
regenerate an expression from AST that when parsed, will give back an
equivalent AST (fixes JEXL-86).
JexlEngine.java: modified because StatementExpression are no longer creating
nodes (#void)

> 2.0 grammar finishing touches & debugger update

> Key: JEXL-85
> URL: https://issues.apache.org/jira/browse/JEXL-85
> Project: Commons JEXL
> Issue Type: Improvement
> Reporter: Henri Biestro
> Fix For: 2.0
>
> Attachments: JEXL-85.patch, JEXL-85.patch
>
> Original Estimate: 0h
> Remaining Estimate: 0h
>
> The Parser.jjt carries some extras that are not (longer) necessary (the
> "debug" field, NODE_USES_PARSER option).
> Tthe {Expression,Statement,Reference}Expression dont need to create real
> nodes.
> There are a few places where the LOOKAHEAD can be reduced or more explicit.
> Some expressions (Reference) are really hard to read partly due to formatting.
> The Debugger is also out of sync with the latest grammar updates (Map
> literals, for).
