NAME

CatalystX::REPL - read-eval-print-loop for debugging your Catalyst application

CONTENTS

VERSION

version 0.04

SYNOPSIS



    package MyApp;

    use Moose;

    # Requires Catalyst 5.8 series
    extends Catalyst;
    with CatalystX::REPL;

    __PACKAGE__->setup(qw/-Debug/);

    1;



DESCRIPTION

Using Carp::REPL with a Catalyst application is hard. That’s because of all the internal exceptions that are being thrown and caught by Catalyst during application startup. You’d have to manually skip over all of those.

This role works around that by automatically setting up Carp::REPL after starting your application, if the CATALYST_REPL or MYAPP_REPL environment variables are set:



 MYAPP_REPL=1 ./script/myapp_server.pl
 # Hit an action
 ...

 42 at lib/MyApp/Controller/Foo.pm line 8.

 # instead of exiting, you get a REPL!
 Trace begun at lib/MyApp/Controller/Foo.pm line 8
 MyApp::Controller::Foo::bar(MyApp::Controller::Foo=HASH(0xc9fe20), MyApp=HASH(0xcea6a4)) called at ...
 ... # Many more lines of stack trace

 $ $c
 MyApp=HASH(0xcea6ec)
 $ $c->req->uri
 http://localhost/foo/bar
 $



Options like warn or nodie can be passed to Carp::REPL by putting them, seperated by commas, into the environment variable:



 MYAPP_REPL=warn,nodie ./script/myapp_server.pl



Carp::REPL uses Devel::REPL for the shell, so direct any questions how how to use or customize the repl at that module.
