Hello,
I created, via a plugin in eclipse 3.5, a custom (multipage)editor for an exotic programming language.
I can't figure out how to create reservedwords that are highligted in my editor. Does anybody know how to do this ?
Thx.

Hi Kitesurfer,
Here is an example of what I have done in my plugin. You'll have to
adapt it a little to make it work in your project. I hope this can help you.
1- In your xxxTextEditor class (that extends TextEditor), initialize the
source viewer configuration, like this :
@Override
protected void initializeEditor()
{
super.initializeEditor();
setSourceViewerConfiguration(new XxxSourceViewerConfiguration(this));
}
2- add xxxSourceViewerConfiguration class that extends
SourceViewerConfiguration to your project.
3- in xxxSourceViewerConfiguration, override getPresentationReconciler
method, and initialize your code scanner in it :
@Override
public IPresentationReconciler getPresentationReconciler(ISourceViewer
sourceViewer)
{
PresentationReconciler reconciler = new PresentationReconciler();
XxxCodeScanner codescanner = new XxxCodeScanner();
DefaultDamagerRepairer dr = new DefaultDamagerRepairer(codescanner);
reconciler.setDamager(dr, IDocument.DEFAULT_CONTENT_TYPE);
reconciler.setRepairer(dr, IDocument.DEFAULT_CONTENT_TYPE);
// ...
}
4- add xxxCodeScanner class that extends RuleBasedScanner to your project
5- in xxxCodeScanner, initialize WordRule, like this :
public xxxCodeScanner()
{
ArrayList<IRule> rules = new ArrayList<IRule>();
rules.add(new WhitespaceRule(new IWhitespaceDetector()
{
@Override
public boolean isWhitespace(char c)
{
return (c == ' ' || c == '\t' || c == '\n' || c == '\r');
}
}));
WordRule wordRule = new WordRule(new IWordDetector()
{
@Override
public boolean isWordPart(char c)
{
return (Character.isLetterOrDigit(c) || c == '_');
}
@Override
public boolean isWordStart(char c)
{
return (Character.isLetter(c) || c == '_');
}
});
Token instructionToken = new Token(...);
for (String keyword : AllYourKeywords)
{
wordRule.addWord(keyword, instructionToken);
}
rules.add(wordRule);
setRules(rules.toArray(new IRule[] {}));
}
Regards
David

I dont debug this sample yet, but find workarond.
In runned sample create new Generic Project and import your *.xxx file to this project. In my case this help - editor opened without critical errors.
PS Can you write more about exotic programming language syntax from first post?

Your workaround to "activate" the plugin works ... thanks. Strange that the plugin on an extension only works within a project (import an xxx-file, or link to an xxx-file) and doesn't work when just opening an xxx-file outside a project. Is this normal behaviour in Eclipse ?
The exotic programming language is the "Transaction Application Langauge" on an HP-system. It's looks a bit like C but has somewhat other syntax and definitly other keywords.
