Acmeist PEG Parser Framework

Pegex is an Acmeist parser framework. It allows you to easily create parsers that will work equivalently in lots of programming languages! The inspiration for Pegex comes from the parsing engine upon which the postmodern programming language Perl 6 is based on. Pegex brings this beauty to the other justmodern languages that have a normal regular expression engine available.

Pegex gets it name by combining Parsing Expression Grammars PEG, with Regular Expessions Regex. That’s actually what Pegex does.

PEG is the cool new way to elegantly specify recursive descent grammars. The Perl 6 language is defined in terms of a self modifying PEG language called Perl 6 Rules. Regexes are familiar to programmers of most modern programming languages. Pegex defines a simple PEG syntax, where all the terminals are regexes. This means that Pegex can be quite fast and powerful.

Pegex attempts to be the simplest way to define new or old Domain Specific Languages DSLs that need to be used in several programming languages and environments. Things like JSON, YAML, Markdown etc. It also great for writing parsers/compilers that only need to work in one language.
