ANTLR::Runtime This is the Perl 5 runtime for ANTLR. It is currently under early development. Most parts are not working yet, and some of those that are need to catch up with the current development version. The good news is that some parts are working, as illustrated by the examples. You'd probably want to take a look at examples/expr/. KNOWN ISSUES ============ * Perl's syntax clashes with ANTLR's StringTemplate ('%') and variable ('$') syntax. Expect error messages like the following. error(146): Expr.g:10:10: invalid StringTemplate % shorthand syntax: '%memory' error(114): Expr.g:18:9: attribute is not a token, parameter, or return value: memory error(114): Expr.g:36:9: attribute is not a token, parameter, or return value: v Currently, it's best to check the syntax of the generated code, like so: $ perl -c ExprLexer.pm ExprLexer.pm syntax OK $ perl -c ExprParser.pm ExprParser.pm syntax OK Or use the lexer/parser in an example.
