B::Flags - Friendlier flags for B
use B::Flags; # some ops print B::main_root->flagspv; print B::main_root->privatepv; print $some_b_sv_object->flagspv;
Stringification of flags.
$foo->flags when passed an object in the
B class will produce a relatively meaningless number, which one would need to grovel through the Perl source code in order to do anything useful with. This module adds
flagspv to the SV and op classes and
privatepv to the op classes, which makes them easier to understand.
Returns stringification of the OP flags.
Adds now SIBLING to abstract the new LASTSIB/MORESIB flags since 5.21/5.22 and the old
op_siblingpointer. Since 5.22 missing the SIBLING flags indicates a PARENT at the
op_sibparentpointer, with -DPERL_OP_PARENT.
Returns stringification of the OP private flags.
- SV->flagspv [type]
Returns stringification of the SV flags.
With the optional type only the flags for the given SvTYPE are used. type 0 is for the SvFLAGS only. This way you can seperate between sv->FLAGS and specialized AvFLAGS, GvFLAGS, CvFLAGS, ... in seperate struct fields.
Note that only the names of bitmasked SV and OP flags are returned, not pseudo flags, like TAINTED, which is stored as magic.
