NAME¶
Pegex::Grammar::Atoms - Pegex Regex Atoms
SYNOPSIS¶
use Pegex::Grammar::Atoms;
DESCRIPTION¶
Atoms are special Pegex rules that represent the small pieces of text that you
can use to build up regular expressions. Usually they are one or two
characters.
It may seem like a waste of time to specify "COLON" in a regex,
instead of a simple ":". There are three reasons this is encouraged.
First is that you are defining a grammar for a new language, and it is worth
the time to be clear and verbose. Second, using an abstraction like this can
help with portability to languages with different regex engines. Finally, it
makes the grammar for Pegex so much simpler, because a "/" is always
a part of the Pegex syntax, and a "SLASH" is part of your grammar.
