NAME

Language::Expr::EvaluatorRole - Specification for Language::Expr interpreter/compiler

VERSION

This document describes version 0.23 of module Language::Expr::EvaluatorRole (in distribution Language-Expr), released on 2014-05-01.

METHODS

parse_dquotestr($raw_parts) -> [{type=>"STR"|"VAR"}, value=>...}, ...]

Instead of parsing parts themselves, consumers can use this method (typically in their rule_dquotestr). This method converts each Expr escapes into Perl string and variables. For example:

parse_dquotestr('abc', "\\t", '\\\\', '$foo', ' ', '${bar baz}') -> (
  {type=>"STR", value=>'abc\t\\'},
  {type=>"VAR", value=>'foo'},
  {type=>"STR", value=>' '},
  {type=>"VAR", value=>'bar baz'},
)

parse_squotestr($raw_parts) => [{type=>STR, value=>...}, ...]

Instead of parsing parts themselves, consumers can use this method (typically in their rule_squotestr). This method converts Expr single quoted string into Perl string.

parse_dquotestr('abc', "\\t", '\\\\', '$foo', ' ', '${bar baz}') -> (
  {type=>"STR", value=>'abc\t\\$foo ${bar baz}'},
)
