DESCRIPTION

26       Using Carp::REPL with a Catalyst application is hard. That's because of
27       all the internal exceptions that are being thrown and caught by
28       Catalyst during application startup. You'd have to manually skip over
29       all of those.
30
31       This role works around that by automatically setting up Carp::REPL
32       after starting your application, if the "CATALYST_REPL" or "MYAPP_REPL"
33       environment variables are set:
34
35        MYAPP_REPL=1 ./script/myapp_server.pl
36        # Hit an action
37        ...
38
39        42 at lib/MyApp/Controller/Foo.pm line 8.
40
41        # instead of exiting, you get a REPL!
42        Trace begun at lib/MyApp/Controller/Foo.pm line 8
43        MyApp::Controller::Foo::bar('MyApp::Controller::Foo=HASH(0xc9fe20)', 'MyApp=HASH(0xcea6a4)') called at ...
44        ... # Many more lines of stack trace
45
46        $ $c
47        MyApp=HASH(0xcea6ec)
48        $ $c->req->uri
49        http://localhost/foo/bar
50        $
51
52       Options like "warn" or "nodie" can be passed to Carp::REPL by putting
53       them, seperated by commas, into the environment variable:
54
55        MYAPP_REPL=warn,nodie ./script/myapp_server.pl
56
57       Carp::REPL uses Devel::REPL for the shell, so direct any questions how
58       how to use or customize the repl at that module.
