NAME
Devel::Trepan -- A new Perl debugger
SUMMARY
A modular, testable, gdb-like debugger in the family of the Ruby
trepanning debuggers.
Features:
* has extensive online-help,
* syntax highlighting of Perl code
* context-sensitive command completion
* out-of-process and remote debugging
* interactive shell support
* code disassembly
* gdb syntax
* easy extensibility at several levels
* command aliases
* a user-supplied command directory
* Perl Plugin module such as [Trepan::Devel::Disassemble](https://github.com/rocky/Perl-Devel-Trepan-Disassemble)
* is more modular
* comes with extensive tests
* is not as ugly as _perl5db_
INSTALLATION
To install this module, run the following commands:
perl Build.PL
./Build
./Build test
./Build install
DESCRIPTION
From a shell:
$ trepan.pl [trepan-opts] perl-program [perl-program-opts]
Or for those who prefer the traditional Perlish way:
$ perl -d:Trepan perl-program [perl-program-opts]
Calling the debugger from inside your Perl program using Joshua ben
Jore's Enbugger:
# This needs to be done once and could even be in some sort of
# conditional code
require Enbugger; Enbugger->load_debugger( 'trepan' );
# Alternatively, to unconditionally load Enbugger and trepan:
use Enbugger 'trepan';
# work, work, work...
# Oops! there was an error! Enable the debugger now!
Enbugger->stop; # or Enbugger->stop if ...
Or if you just want POSIX-shell-like `set -x` line tracing:
$ trepan.pl -x -- perl-program [perl-program-opts]
Inside the debugger tracing is turned on using the command `set
trace print`.
There is extensive help from the `help` command.
