How can I interface with the Perl debugger API?

Question

有没有办法连接perl用于控制程序调试的Perl调试器API？

Answer 1

The default Perl debugger was not designed with a clean API to interact with, so the easiest way is probably not to use it, but to use Devel::ebug , which offers an API to an alternative debugger. You can also trigger the debugger from inside your code, calling an interactive debugger session, with Enbugger .

Answer 2

It's all in the perldebug , perldebguts , and DB documentation.

In addition, I've written a Creating a Perl Debugger which should get you started. I have a section on custom Perl debuggers in Mastering Perl too.

Answer 3

You can read about the perl debugger at perldoc perldebug and perldoc perldebtut . You can invoke the debugger with the -d option, ie perl -d myscript.pl .

Answer 4

See "Programming Perl" 20.5.1 -> "Writing your own debugger", also see perldoc perlvar $PERLDB.

What you want to do is to implement the DB::DB() sub.
