-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello,
I want to write an ANTLR-Lexer and -Parser for a Literate Programming language. The idea is to embed code fragments in various languages in a LaTeX document and generate source files on-the-fly. The languages allows to change the special character used to denote the beginning of a code snippet and the special character used inside these snippets to denote inclusion of other snippets. This is needed because some "guest"-languages might need a pre-defined special character themselves. The special character can be changed anywhere in the source text by using <OLDSPECIAL>=<NEWSPECIAL> where <OLDSPACIAL> is the old special character and <NEWSPECIAL> is the new special character that should be active after that instruction. My idea was to modify the lexer such that it has a member variable "char cur_special" that is set to the current special character and match against it in a rule "fragment SCHAR : cur_special" such that the token stream abstracts from the different possible special characters. At the moment, the only way I see to accomplish this is to manually modify the generated lexer in many places. Is there perhaps a built-in functionality in ANTLR 3.2 i could use? I couldn't find anything in the archives searching for "lexer match member". I really don't need a full how-to but a gentle nudge in the correct direction. Thanks in advance Frederic P.S. Sorry if this is/becomes a repost. My first mail didn't make it through - - perhaps because it had a PGP signature attachment -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxo3UcACgkQOBEXShUwZO0hagCeNY82qTh5wRk7SmvCAxB9oAfk 1RwAni+IC77x5IBHbw2Tp4SQ4qv1RIS7 =U+NM -----END PGP SIGNATURE----- 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.
