Hello - just another question
I am trying to modify the SQL XML language definition
I have replaced the SystemVariableToken RegexPatternGroup with an explicit list of system variables - so that, @@TEST, for example, is not recognised as a system variable
However, @@TEST then gets recognised as a single @ and then a VariableToken @@
I wanted to create a lookBehind macro that would stop the VariableToken from allowing things that start with @@ from being highlighted as a variable.
So I tried LookBehind="(?<!@@)" in the VariableToken declaration in the XML - but this complained about the < character in XML. So I tried LookBehind="(?<!@@)". This let the XML be loaded, but as soon as an '@' was typed in the document, would raise an ApplicationException with the message 'Op code not implemented: 12'.
So - can anyone help me modify the following XML so that variable tokens do not match on items with two @@ at the start?
