com.google.collide.client.documentparser.DocumentParser
Parser for a document that delegates to CodeMirror. This class attaches to a document and re-parses whenever the contents changes. It uses an incremental parser allowing it to resume parsing from the beginning of the changed line.

    editor.setDocument(document);


    editor.getInput().getActionExecutor().addDelegate(TextActions.INSTANCE);


    PathUtil path = new PathUtil("test.css");
    DocumentParser documentParser = createDocumentParser(path);
    Autoindenter autoindenter = Autoindenter.create(documentParser, editor);


    LineFinder lineFinder = editor.getDocument().getLineFinder();
    editor.getSelection().setSelection(
        lineFinder.findLine(line1), column1, lineFinder.findLine(line2), column2);
