Hi guys, I've been using Perl 5.010 regex to do some parsing, e.g. in Data::Csel [1] to parse CSS-selector-like expression, due to its relatively low startup overhead compared to Marpa or Regexp::Grammars. A couple of days ago, after reading about a topic in perl6 subreddit [2], I did a comparison benchmark [5] for a simple arithmetic parser using perl [3] vs Marpa [4]. My questions:
1) how do I improve the Marpa version's performance? 2) how to remove the "Earley item count (N) exceeds warning threshold"? This happens for 1+1+..+1 (100x) expression but not for the 20x or below. 3) how do I make right associativity work? The Marpa version still evaluates ** operator left to right. regards, perlancar [1] https://metacpan.org/pod/Data::CSel [2] https://www.reddit.com/r/perl6 [3] https://metacpan.org/pod/release/PERLANCAR/PERLANCAR-Parse-Arithmetic-0.001/lib/PERLANCAR/Parse/Arithmetic.pm [4] https://metacpan.org/pod/release/PERLANCAR/PERLANCAR-Parse-Arithmetic-0.001/lib/PERLANCAR/Parse/Arithmetic/Marpa.pm [5] https://metacpan.org/pod/release/PERLANCAR/Bencher-Scenarios-PERLANCARParseArithmetic-0.002/lib/Bencher/Scenario/PERLANCARParseArithmetic/parse_arithmetic.pm -- You received this message because you are subscribed to the Google Groups "marpa parser" group.
