Adding simple code formatting to a SourceViewer? [message #333544]

What's the quickest/simplest way to add rudimentary JavaScript formatting
to a subclass of a SourceViewer? I'm confused about whether I need a
ContentFormatter, a ContentFormaterStrategy, whether I should use a
multi-pass formatter, etc.

Is there a simple, straightforward set of things I can add to a
SourceViewer that will do minimal formatting, like indenting, for
JavaScript? I'd like to use the JSDT editor, but I don't have that luxury
(I'm retrofitting some old code and don't have all the original source).

Thanks!

Turned out to be pretty simple... For anyone else who comes along wanting
this:

final CodeFormatter codeFormatter =
ToolFactory.createCodeFormatter(DefaultCodeFormatterOptions. getEclipseDefaultSettings().getMap());
TextEdit fmtText =
codeFormatter.format(CodeFormatter.K_JAVASCRIPT_UNIT,
fSourceViewer.getDocument().get(), 0,
fSourceViewer.getDocument().getLength(), 0, null);

try {

fmtText.apply(fSourceViewer.getDocument());
} catch (Exception e) {
System.out.println("Caught text format exception: " +
e.getMessage());

}
