B::Terse(3) Perl Programmers Reference Guide B::Terse(3)NAMEB::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 datastruc‐
ture, 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.
