Template::Alloy::Operator 1.006

Template::Alloy::Operator is a Perl module that provides the regexes necessary for Template::Alloy::Parse to parse operators and place them in their appropriate precedence.

It also provides the play_operator method which is used by Template::Alloy::Play and Template::Alloy::Compile for playing out the stored operator ASTs.

ROLE METHODS

play_operator

Takes an operator AST in the form of

[undef, +, 1, 2]

Essentially, all operators are stored in RPN notation with a leading "undef" to disabiguate operators in a normal Alloy expression AST.

define_operator

Used for defining new operators.

See Template::Alloy for more details.
