MirOS Manual: B::Terse(3p)


ext::B::B::Terse(Perl Programmers Reference Gext::B::B::Terse(3p)

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 compa-
     tibility 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, how-
     ever, 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 ver-
     sion 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>.
