Adding tokens at runtime

SyntaxEditor for Windows Forms Forum

Posted 18 years ago by John Youren

I am trying to dynamically add [multi-word] tokens at runtime, here is the code I have.

Documents[tabID].getCode().Document.LoadLanguageFromXml(Application.StartupPath + "\\Syntax\\" + Variables.Compiler + ".xml", 0);
                        // Set up TPC's
                        if (Variables.Compiler == Constant.CompilerDBP)
                            Documents[tabID].getCode().Document.Language.IsUpdating = true;
                            for(int pattern = 0; pattern < DBPSyntax.keywords.Count; pattern++)
                                Console.WriteLine(DBPSyntax.keywords[pattern].Replace(" ", "\\s+"));
                                Documents[tabID].getCode().Document.Language.DefaultLexicalState.LexicalPatternGroups.Add(new ActiproSoftware.SyntaxEditor.LexicalPatternGroup(ActiproSoftware.SyntaxEditor.LexicalPatternType.Regex, "ReservedWordToken", Documents[tabID].getCode().Document.Language.HighlightingStyles["ReservedWordStyle"], DBPSyntax.keywords[pattern].Replace(" ", "\\s+"), "{NonWordMacro}"));
                            Documents[tabID].getCode().Document.Language.IsUpdating = false;
The problem is even a simple word such as 'hello' won't highlight, even though I have stepped through it getting added.

Any ideas? :)

Yes the lexical pattern groups are scanned in order. You probably have an Identifier pattern matching
them before they get to your new patterns. Use the Insert method and put them up higher in the
LexicalPatternGroups collection.

As a side note, you can always load your language in our sample project. It shows the token in the
statusbar that the caret is over. That helps debug language problems like this.
