Re: [cdt-core-dev] Eclipse Error Parser.

Hello!

I think that ErrorParserManager feeds IErrorParser per line, as such your
regexp is only ever applied to one line at a time.

If you're using MinGW gcc you can use -fmessage-length=0 option to force
single-line output.

Otherwise, I guess you can just implement some kind of state machine in,
say, a ErrorPattern decorator to build a single line from multiple lines.
i.e., something like:

class CustomErrorPattern extends ErrorPattern {

	public CustomErrorPattern(ErrorPattern orig) {
		this.orig = orig;
		this.isError = false;
		this.sb = null;
	}

	private static Pattern errorPattern = Pattern.compile("XXX");
	private static Pattern continuationPattern = Pattern.compile("YYY");

        private ErrorPattern orig; // The decorated error pattern (its
regexp should match "XXX" or "XXX YYY*")

	private StringBuffer sb;
	private boolean isError;

	/** @Override */
	public boolean processLine(String line, ErrorParserManager eoParser) {
		if (errorPattern.matcher(line).matches()) {
			if (isError) {
				orig.processLine(sb.toString(), eoParser);
			} else {
				isError = true;
			}
			sb = new StringBuffer(line);
		} else if (continuationPattern.matcher(line).matches() && isError) {
			sb.append(' ').append(line);
		} else {
			isError = false;
		}
		return false;
	}
}

((note: the code above assumes the last line isn't an error line :P))

Hope this helps!
