Pegex Syntax
Pegex has a fairly simple set of syntax constructs. This document details them all.
A Pegex grammar is just a set of named rules. They look like this
rule_name_1: <rule>* <body> /1/
rule_name_2: /rule body 2/A rule is a name followed by a ':' followed by a rule body. It can optionally end with a semicolon, if you want to put more than one on a line.
Basic Tokens
Pegex only has 3 kinds of basic tokens:
- Rule Reference
-
A rule reference is the name of a rule inside angle brackets.
<sub_rule_name> - Regular Expression
-
A regular expression is a string inside forward slashes.
/regular expression/ - Error Message
-
An error message is a string inside backticks.
