NAME

6       Dancer::Config::Object - Access the config via methods instead of
7       hashrefs
8

VERSION

10       version 1.3513
11

DESCRIPTION

13       If "strict_config" is set to a true value in the configuration, the
14       "config()" subroutine will return an object instead of a hashref.
15       Instead of this:
16
17        my $serializer = config->{serializer};
18        my $username   = config->{auth}{username};
19
20       You get this:
21
22        my $serializer = config->serializer;
23        my $username   = config->auth->username;
24
25       This helps to prevent typos. If you mistype a configuration name:
26
27        my $pass = config->auth->pass;
28
29       An exception will be thrown, tell you it can't find the method name,
30       but listing available methods:
31
32        Can't locate config attribute "pass".
33        Available attributes: password, username
34
35       If the hash key cannot be converted into a proper method name, you can
36       still access it via a hash reference:
37
38        my $some_value = config->{'99_bottles'};
39
40       And call methods on it, if possible:
41
42        my $sadness = config->{'99_more_bottles'}->last_bottle;
43
44       Hash keys pointing to hash references will in turn have those
45       "objectified".  Arrays will still be returned as array references.
46       However, hashrefs inside of the array refs may still have their keys
47       allowed as methods:
48
49        my $some_value = config->some_list->[1]->host;
50

METHOD NAME DEFINITION

52       We use the following regular expression to determine if a hash key
53       qualifies as a method:
54
55        /^[[:alpha:]_][[:word:]]*$/;
56
57       Note that this means "naïve" (note the dots over the i) can be a method
58       name, but unless you "use utf8;" to declare that your source code is
59       UTF-8, you may have disappointing results calling "config->naïve".
60       Further, depending on your version of Perl and the software to read
61       your config file ... well, you get the idea. We recommend sticking with
62       ASCII identifiers if you wish your code to be portable.

64       Patches/suggestions welcome.
