| 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. |
