Solved : “these characters need to be tokenized” for netbeans lang development
When developing highlight for new language, the antlr grammar has to return all tokens, you can’t skip token, otherwise your netbeans will throw this exception:
java.lang.IllegalStateException: Lexer com.github.mcheung63.netbeans.antlr.syntax.antlr3.Antlr3EditorLexer@7da1fd06 returned null token but lexerInput.readLength()=1 lexer-state: null tokenStartOffset=1101, readOffset=1102, lookaheadOffset=1103 Chars: "\n" - these characters need to be tokenized. Fix the lexer to not return null token in this state
