David Majda 4b51e6a6d3 Quote null characters in regexps, IE does not like them. 2010-04-16 08:53:02 +02:00
David Majda 7fc491412d Work around the fact that IE does not recognize "\v" in strings. 2010-04-14 21:29:05 +02:00
David Majda 6abda95a99 Made regexps generated for empty character classes ("[]" and "[^]") work in IE. 2010-04-14 21:08:35 +02:00

David Majda e63f64a3d5 Make the generated parsers standalone (no runtime is required). 
This and also speeds up the benchmark suite execution by 7.83 % on V8.

David Majda 3f85a9ca84 Regenerated the metaparser with one-level rule cache. 2010-04-11 17:02:53 +02:00
David Majda 24d38f74b9 Replaced two-level rule cache with a one-level one. 
This leads to simpler code and also speeds up the benchmark suite execution by
5,89 % on V8.

David Majda 37521cffa5 Error messages now do not contain duplicities. 2010-04-11 15:30:02 +02:00
David Majda 714512f232 Implemented generic AST node extension mechanism. 2010-04-11 14:48:52 +02:00
David Majda 1aa3d8e07e Implemented a nop (no operation) function and used it on few places. 2010-04-11 14:16:38 +02:00
David Majda 6a194e8f68 Added example JavaScript parser. 2010-04-11 13:18:23 +02:00
David Majda 16f238a64d Fixed comment heading. 2010-04-11 12:41:25 +02:00
David Majda 3291c70d97 Added \uFEFF (BOM) to the definition of whitespace in the metagrammar. 
The Rhino bug that prevented inclusion of \uFEFF among the whitespace characters
is no longer relevant here because we compile character classes into regexps
now, which avoids the infinite recursion.
 2010-04-11 11:45:05 +02:00
David Majda 383c5acaa6 Replaced \xA0 by \u00A0 in the whitespace definition in the metagrammar. 
This is purely stylistic change.
 2010-04-11 11:18:42 +02:00
David Majda db616f0b77 Made the "version" variable scope smaller. 2010-04-11 11:15:40 +02:00
David Majda c5cc545209 "rake metaparser" and "rake minify" now always generate the target files. 
Until now, these tasks looked at the file times and generated the target files
only when they were older than the source files. This caused problems when I
mainupulated the lib/metagrammar.* files by hand sometimes, replaced them from
backups after screw-ups, etc.

David Majda 51232fd652 I don't like the .txt extension after all :-) 2010-04-11 10:59:13 +02:00
David Majda 9488291ac0 Converted README to GitHub Flavored Markdown.

David Majda 6f510a0336 The cache does not remember match length but next position after the match. 
This leads to simpler and faster code because it avoids one addition and
subtraction.
