Dancer::Config::Object(3p)

NAME
Dancer::Config::Object - Access the config via methods instead of hashrefs

VERSION
version 1.3522

DESCRIPTION
If "strict_config" is set to a true value in the configuration, the config() subroutine will return an object instead of a hashref. Instead of this:

 my $serializer = config->{serializer};
 my $username   = config->{auth}{username};

You get this:

 my $serializer = config->serializer;
 my $username   = config->auth->username;

This helps to prevent typos. If you mistype a configuration name:

 my $pass = config->auth->pass;

An exception will be thrown, tell you it can't find the method name, but listing available methods:

 Can't locate config attribute "pass".
 Available attributes: password, username

If the hash key cannot be converted into a proper method name, you can still access it via a hash reference:

 my $some_value = config->{'99_bottles'};

And call methods on it, if possible:

 my $sadness = config->{'99_more_bottles'}->last_bottle;

Hash keys pointing to hash references will in turn have those "objectified". Arrays will still be returned as array references. However, hashrefs inside of the array refs may still have their keys allowed as methods:

 my $some_value = config->some_list->[1]->host;

METHOD NAME DEFINITION
We use the following regular expression to determine if a hash key qualifies as a method:

 /^[[:alpha:]_][[:word:]]*$/;

Note that this means "naïve" (note the dots over the i) can be a method name, but unless you "use utf8;" to declare that your source code is UTF-8, you may have disappointing results calling "config->naïve". Further, depending on your version of Perl and the software to read your config file ... well, you get the idea. We recommend sticking with ASCII identifiers if you wish your code to be portable.

Patches/suggestions welcome.
