Antlr4 performance issue due to non greedy grammar

[tanuja dubal]

Hi I have below grammar to match all character except '['.

any_Character:~'['+;  

printStatement:Any_Character+;

codeStatement:  '[' .+ END

This grammar to split the statement between printstatement and code statement, where code statement starts with '['. If I use this grammar then it will take more than 5 mins for parsing of 1000LOC.

Please suggest the solution to improve the performance.

You need a Lexer rule nit a parser rule. Lexer rules start with UPPER case. However this rule will continue pretty much everything so you probably need lexer modes.
