Module Version: 1.05   Source   Latest Release: perl-5.21.2

NAME ^

B::Terse - Walk Perl syntax tree, printing terse info about ops

SYNOPSIS ^

        perl -MO=Terse[,OPTIONS] foo.pl

DESCRIPTION ^

This version of B::Terse is really just a wrapper that calls B::Concise with the -terse option. It is provided for compatibility with old scripts (and habits) but using B::Concise directly is now recommended instead.

For compatibility with the old B::Terse, this module also adds a method named terse to B::OP and B::SV objects. The B::SV method is largely compatible with the old one, though authors of new software might be advised to choose a more user-friendly output format. The B::OP terse method, however, doesn't work well. Since B::Terse was first written, much more information in OPs has migrated to the scratchpad datastructure, but the terse interface doesn't have any way of getting to the correct pad. As a kludge, the new version will always use the pad for the main program, but for OPs in subroutines this will give the wrong answer or crash.

AUTHOR ^

The original version of B::Terse was written by Malcolm Beattie, <mbeattie@sable.ox.ac.uk>. This wrapper was written by Stephen McCamant, <smcc@MIT.EDU>.
