Debugger subroutine for ptkdb that places a breakpoint, with or without a condition, on the next executable line.
use strict ; use vars qw/@dbline/ ; sub Debugger { return unless defined $DB::single && defined %main::Devel::ptkdb:: + ; my($package, $fname, $line) = caller ; my($expr) = shift ; local(*dbline) = local(*dbline) = $main::{'_<' . $fname} ; $line += 1 ; for( ; $line < @dbline && !DB::checkdbline($fname, $line) ; $line +++ ) {} return if( $line == @dbline ) ; if( defined $expr ) { Devel::ptkdb::condbrkpt($fname, $line, $expr) ; } else { Devel::ptkdb::brkpt($fname, $line) ; } } ## ## Example of Use ## sub foo1 { Debugger() ; } sub foo2 { print "Hi\n" ; } &foo1 ; Debugger() ; print "Hello world!\n" ; my($i) ; for( $i = 0 ; $i < 20 ; $i++ ) { Debugger('$i > 15') ; print "$i\n" ; }

Features

  • Function call needn't be removed when debugging isn't enabled

    Issues

  • If placed at the bottom of a subroutine, a breakpoint is placed at the beginning of the next, or nothing, if there are more executable lines in the file.
  • Breakpoints don't actually appear until AFTER execution has passed over the Debugger() call.
