MessageConsole + Hyperlinks [message #304254]

Hi,

I am trying to add hyperlinks to my console (a la Java exception
reporting) so that I can navigate from errors to the source line/column
of my programs. I use messageConsole.newMessageStream() to get my debug
and error message streams and print messages to the console using their
..print() and .println() methods. However, when I try to add a hyperlink
using the addHyperlink method, I get a BadLocationException. I have
inspected the messageConsole.getDocument().getLength() and it is
constantly 0 (and that is the reason of the exception) although I have
printed messages using the print-println methods before... Any ideas or
examples?

In case it helps I am using Eclipse 3.1.0 under WinXP.

Cheers,
Dimitrios

The asynchronous nature of the console make this more difficult that it
seems it should be because writing to the console doesn't mean that the
text is actually in the document yet. You can get around this by using a
pattern matcher.

From ProcessConsole.java:

private class ConsoleLogFilePatternMatcher implements
IPatternMatchListener {
String fFilePath;

public ConsoleLogFilePatternMatcher(String filePath) {
fFilePath = escape(filePath);
}

private String escape(String path) {
StringBuffer buffer = new StringBuffer(path);
int index = buffer.indexOf("\\"); //$NON-NLS-1$
while (index >= 0) {
buffer.insert(index, '\\');
index = buffer.indexOf("\\", index+2); //$NON-NLS-1$
}
return buffer.toString();
}

public String getPattern() {
return fFilePath;
}

public void matchFound(PatternMatchEvent event) {
try {
addHyperlink(new ConsoleLogFileHyperlink(fFilePath),
event.getOffset(), event.getLength());
removePatternMatchListener(this);
} catch (BadLocationException e) {
}
}

public int getCompilerFlags() {
return 0;
}

public String getLineQualifier() {
return null;
}

public void connect(TextConsole console) {
}

public void disconnect() {
}
}

Hi Kevin,

I tried that and it worked :)

Thanks,
