Usually what you would do is to lex (or create an AST or whatever) the full document on document load and document change (probably asynchronously!), and make the highlighter just access that information based on the line it is supposed to highlight. > Thanks in advance. > > Jeremy > _______________________________________________ > Qt-creator mailing list > [email protected] > http://lists.qt-project.org/mailman/listinfo/qt-creator -- Eike Ziller Principal Software Engineer The Qt Company GmbH Rudower Chaussee 13 D-12489 Berlin [email protected] http://qt.io Geschäftsführer: Mika Pälsi, Juha Varelius, Mika Harjuaho Sitz der Gesellschaft: Berlin, Registergericht: Amtsgericht Charlottenburg, HRB 144331 B _______________________________________________ Qt-creator mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/qt-creator
