Skipping X Number of Iterations before Stopping on a Break Point in Perl?

Question

I am running a script under perl -d and want to break execution at line 243 in this case. perl -d scriptname loads the script in to the debugger and b 243 sets the break point. c then Enter starts the program which runs until it reaches the desired line at which point it stops. All I want to do is get it to loop multiple times through this point and then stop.

This is similar to the behavior of gdb where you could tell it to stop after, say, 250 passes through the break point.

Answer 1

I know of several options for that:

1. Use a package-scope count variable: e.g, do:

   b 243 ((++$::_LINE_243) == 250)
   

2. source a file (see "source" on "perldoc perldebug") that will contain several "c" statements.
3. Maybe try Devel::Trepan instead: https://metacpan.org/release/Devel-Trepan .
