ExtUtils::ParseXS::Eval - Clean package to evaluate code in

=head1 SYNOPSIS
|
|
|
|
use ExtUtils::ParseXS::Eval;
|
|
my $rv = ExtUtils::ParseXS::Eval::eval_typemap_code(
|
|
$parsexs_obj, "some Perl code"

|
=head1 SUBROUTINES

|
=head2 $pxs->eval_output_typemap_code($typemapcode, $other_hashref)
|
|
|
|
Sets up various bits of previously global state
|
|
(formerly ExtUtils::ParseXS package variables)
|
|
for eval'ing output typemap code that may refer to these
|
|
variables.
|
|
|
|
Warns the contents of C<$@> if any.
|
|
|
|
Not all these variables are necessarily considered "public" wrt. use in
|
|
typemaps, so beware. Variables set up from the ExtUtils::ParseXS object:
|
|
|
|
$Package $ALIAS $func_name $Full_func_name $pname
|
|
|
|
Variables set up from C<$other_hashref>:

$var $type $ntype $subtype $arg

Eventually, with better documentation and possible some cleanup,
|
|
this could be part of C<ExtUtils::Typemaps>.
