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.
