NAME

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

VERSION

version 0.20

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}'},
 )
