I'm writing a SourceViewer for a language similar to Java. I'd like to
partition the document into 4 buckets:
#1 Single line comments
#2 Multi line comments
#3 String literals
#4 Everything else
I'm running into trouble on #4. What I've got is a subclass of
RuleBasedPartitionScanner that looks something like this:
List<IPredicateRule> rules = new ArrayList<IPredicateRule>();
// Single line comments
rules.add(new EndOfLineRule("//", TokenType.COMMENT_SINGLE));
// Multi line comments
rules.add(new MultiLineRule("/*", "*/", TokenType.COMMENT_MULTI));
// String literals
rules.add(new SingleLineRule("\"", "\"", TokenType.LITERAL_STR));
setDefaultReturnToken(DEFAULT);
setPredicateRules(rules.toArray(new IPredicateRule [rules.size()]));
The FastPartitioner is working fine for the first 3 types. But
"everything else" is getting detected as a bunch of 1-character tokens
of the same default type.
So I guess my question is two-part:
1) Is there a reason that adjacent tokens of the same content type are
not merged into a single partition?
2) What is the best way to get a big block of "everything else" code
detected as a single block with the default content type?
Thanks,
Ben
