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'}, )
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}'}, )
