NAME

FP::AST::Perl -- abstract syntax tree for representing Perl code

SYNOPSIS

use FP::AST::Perl ":all";
use FP::List;

is Get(LexVar('foo'))->string, '$foo';
is Get(PackVarScalar "foo")->string, '$foo';
is Get(PackVarArray "foo")->string, '@foo';
is Get(PackVarHash "foo::bar")->string, '%foo::bar';

my $foo= PackVarCode("foo");
my $arrayfoo= PackVarArray("foo");
my $lexfoo= LexVar("foo");
is App(Get($foo), list())->string,
   '&foo()';
is AppProto(Get($foo), list())->string,
   'foo()';
is AppProto(Get($lexfoo), list(Ref($foo)))->string,
   '$foo->(\&foo)';
is AppProto(Get($lexfoo), list(Get($lexfoo), Get($arrayfoo), Ref($arrayfoo)))->string,
   '$foo->($foo, @foo, \@foo)';
is AppProto(Get($foo), list(Get(LexVar 'foo'), Literal(Number 123)))->string,
   'foo($foo, 123)';
is AppProto(Get($foo), list(Get($lexfoo), Literal(String 123)))->string,
   'foo($foo, \'123\')';

DESCRIPTION

This is not a parser, and hence should be outside the scope of the "can only parse Perl at runtime" issue.

The longer term aim is to support all of Perl, and to support conversion to and maybe from an op tree.

Implements: FP::Abstract::Pure, FP::Abstract::Show, FP::Abstract::Equal.
