NAME

       Devel::REPL::Profile - code to execute when re.pl starts

SYNOPSIS

	package Devel::REPL::Profile::MyProject;

	use Moose;
	use namespace::clean -except => [ 'meta' ];

	with 'Devel::REPL::Profile';

	sub apply_profile {
	    my ($self, $repl) = @_;
	    # do something here
	}

	1;

DESCRIPTION

       For particular projects you might well end up running the same commands each time the REPL shell starts up - loading Perl modules, setting
       configuration, and so on.

       A mechanism called profiles exists to let you package and distribute these start-up scripts, as Perl modules.

USAGE

       Quite simply, follow the "SYNOPSIS" section above to create a boilerplate profile module. Within the "apply_profile" method, the $repl
       variable can be used to run any commands as the user would, within the context of their running "Devel::REPL" shell instance.

       For example, to load a module, you might have something like this:

	sub apply_profile {
	    my ($self, $repl) = @_;
	    $repl->eval('use Carp');
	}

       As you can see, the "eval" method is used to run any code. The user won't see any output from that, and the code can "safely" die without
       destroying the REPL shell. The return value of "eval" will be the return value of the code you gave, or else if it died then a
       "Devel::REPL::Error" object is returned.

       If you want to load a "Devel::REPL" plugin, then use the following method:

	$repl->load_plugin('Timing');

       The "load_plugin" and "eval" methods should cover most of what you would want to do before the user has access to the shell. Remember that
       plugin features are immediately available, so you can load for example the "LexEnv" plugin, and then declare "my" variables which the user
       will have access to.

   Selecting a Profile
       To run the shell with a particular profile, use the following command:

	system$ re.pl --profile MyProject

       Alternatively, you can set the environment variable "DEVEL_REPL_PROFILE" to MyProject.

       When the profile name is unqualified, as in the above example, the profile is assumed to be in the "Devel::REPL::Profile::" namespace.
       Otherwise if you pass something which contains the "::" character sequence, it will be loaded as-is.
