NAME

Perl::ToPerl6::Transformer::BasicTypes::Strings::Interpolation - Format ${x} correctly

AFFILIATION

This Transformer is part of the core Perl::ToPerl6 distribution.

DESCRIPTION

In Perl6, contents inside {} are now executable code. That means that inside interpolated strings, "${x}" will be parsed as "${x()}" and throw an exception if x() is not defined. As such, this transforms "${x}" into "{$x}":

  "The $x bit"      --> "The $x bit"
  "The $x-30 bit"   --> "The $x\-30 bit"
  "\N{FOO}"         --> "\c[FOO]"
  "The \l$x bit"    --> "The {lc $x} bit"
  "The \v bit"      --> "The  bit"
  "The ${x}rd bit"  --> "The {$x}rd bit"
  "The \${x}rd bit" --> "The \$\{x\}rd bit"

Many other transforms are performed in this module, see the code for a better idea of how complex this transformation really is.

Transforms only interpolated strings outside of comments, heredocs and POD.

CONFIGURATION

This Transformer is not configurable except for the standard options.
