Some international characters kill RubyYaccLexer
------------------------------------------------
Key: JRUBY-1189
URL: http://jira.codehaus.org/browse/JRUBY-1189
Project: JRuby
Issue Type: Bug
Components: Parser
Affects Versions: JRuby 1.0.0
Environment: Windows Vista, JDK 1.6
Reporter: Chris Williams
In RDT/RadRails we pass down the text of an open editor to the lexer/parser for
a few processes like syntax coloring/partitioning and code analysis.
Users are reporting some errors when typing in characters like the British
pound symbol. The Parser is throwing an unchecked runtime exception trying to
parse the character as an integer to formulate a SyntaxException. This is on
line 1411 of RubyYaccLexer.
I'm not sure if the character should be valid or not, but at the very least I'd
hope for better behavior in handling it.
Ideally the code would wrap the call to Integer.parseInt(String str, int radix)
in a try/catch, or it would use some other method that doesn't throw exceptions
(but could return weird answers), like Character.digit(char ch, int radix).
