# NAME

# NAME

Perl::Critic::Policy::Catalyst::ProhibitUnreachableCode - Don't write code after an unconditional Catalyst detach.

# DESCRIPTION

This module was forked from
[Perl::Critic::Policy::ControlStructures::ProhibitUnreachableCode](https://metacpan.org/pod/Perl::Critic::Policy::ControlStructures::ProhibitUnreachableCode)
version `1.132` and modified to fit.

The primary difference is this module looks for these two
Catalyst specific bits of code as signifying a terminating statement:

```
$c->detach();
$c->redirect_and_detach();
```

The `redirect_and_detach` context method is available if you are using
[Catalyst::Plugin::RedirectAndDetach](https://metacpan.org/pod/Catalyst::Plugin::RedirectAndDetach).

# PARAMETERS

## context\_methods

By default this policy looks for the `detach` and `redirect_and_detach`
context methods. You can specify additional context methods to look for
with the `context_methods` parameter. In your `.perlcriticrc` this
would look something like:

```perl
[Catalyst::ProhibitUnreachableCode]
context_methods = my_detaching_method my_other_detaching_method
```

This policy would then consider all of the following lines as
terminating statements:

```perl
$c->detach();
$c->redirect_and_detach();
$c->my_detaching_method();
$c->my_other_detaching_method();
```

## controller\_methods

Sometimes controllers have in-house methods which call `detach`, you
can specify those:

```
[Catalyst::ProhibitUnreachableCode]
controller_methods = foo bar
```

Then this policy would look for any package with `::Controller::` in
its name and would consider the following lines as terminating
statements:

```perl
$self->foo();
$self->bar();
```

There are no default methods for this parameter.
