I'd like to use Antlr to create a syntax highlighter. I've taken the Java.g grammer offered up at the web site for Java 6 and ran it through org.antlr.Tool.
It produced a lot of warning messages. Is this normal? Below is the half-screen of warnings. java -cp /Users/alan/.m2/repository/org/antlr/antlr-runtime/3.2/antlr- runtime-3.2.jar:/Users/alan/.m2/repository/antlr/antlr/2.7.7/ antlr-2.7.7.jar:/Users/alan/.m2/repository/org/antlr/stringtemplate/ 3.2.1/stringtemplate-3.2.1.jar:/Users/alan/.m2/repository/org/antlr/ antlr/3.2/antlr-3.2.jar org.antlr.Tool Java.g warning(209): Java.g:1767:1: Multiple token rules can match input such as "'-'": SUBSUB, SUB, SUBEQ As a result, token(s) SUB,SUBEQ were disabled for that input warning(209): Java.g:1811:1: Multiple token rules can match input such as "'c'": CASE, CATCH, CHAR, CLASS, CONST, CONTINUE, IDENTIFIER As a result, token(s) CATCH,CHAR,CLASS,CONST,CONTINUE,IDENTIFIER were disabled for that input warning(209): Java.g:1791:1: Multiple token rules can match input such as "'%'": PERCENT, PERCENTEQ As a result, token(s) PERCENTEQ were disabled for that input warning(209): Java.g:1811:1: Multiple token rules can match input such as "'t'": THIS, THROW, THROWS, TRANSIENT, TRY, TRUE, IDENTIFIER As a result, token(s) THROW,THROWS,TRANSIENT,TRY,TRUE,IDENTIFIER were disabled for that input warning(209): Java.g:1799:1: Multiple token rules can match input such as "'!'": BANG, BANGEQ -- Alan Gutierrez - [email protected] - http://twitter.com/bigeasy List: http://www.antlr.org/mailman/listinfo/antlr-interest Unsubscribe: http://www.antlr.org/mailman/options/antlr-interest/your-email-address -- You received this message because you are subscribed to the Google Groups "il-antlr-interest" group.
