b::terse(3pm)
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.
