Retrieving DeletedToken Text - SyntaxEditor for Windows Forms Forum

Posted 18 years ago by Marianne

When trying to get the deleted token text like so:

                foreach (Token t in document.Tokens.DeletedTokens)
                {
                    if (t.Key == "VariableDefinitionToken") 
                        Console.WriteLine("Def deleted: " + document.GetTokenText(t));
                }

It only ends up giving me the text at the location formerly occupied by the token, but now that it's deleted the document.GetTokenText() method does not give me the deleted tokens text. How can I retrieve the deleted token's text? Thanks.

Hi Marianne,

For memory reasons we don't store the text of the token with each token. In the PostParse method of the semantic parser, you know the full text of the completed document. You also know the change start location which is indicated in the modification's StartOffset. You know the text that was deleted (if any) in the modification's DeletedText property and you know what was inserted (if any) in the modification's InsertedText property. By combining that sort of information you could derive the text that was deleted by looking at a combination of what is currently in the document (which really also includes the inserted text) and the DeletedText in the modification if the token's range falls in that.
