hello!
I have created a PEG parser library for racket. It's basically regex
turned up to 11.
It lets you write parsers like this:
(define-peg marked-palindrome
(or "m"
(and "1" marked-palindrome "1")
(and "0" marked-palindrome "0")))
or like this:
#lang peg
expr <- sum ;
sum <-- (product ('+' / '-') sum) / product ;
product <-- (value ('*' / '/') product) / value ;
value <-- number / '(' expr ')' ;
number <-- [0-9]+ ;
It is available from the racket pkgs repository, or on github:
* https://pkgd.racket-lang.org/pkgn/package/peg
* https://github.com/rain-1/racket-peg
I welcome feedback and hope that the library is of use.
