7 | =head1 NAME | ||||
8 | |||||
9 | DateTime::Format::Builder::Parser::Quick - Use another formatter, simply | ||||
10 | |||||
11 | =head1 SYNOPSIS | ||||
12 | |||||
13 | use DateTime::Format::Builder ( | ||||
14 | parsers => { parse_datetime => [ | ||||
15 | { Quick => 'DateTime::Format::HTTP' }, | ||||
16 | { Quick => 'DateTime::Format::Mail' }, | ||||
17 | { Quick => 'DateTime::Format::IBeat' }, | ||||
18 | ]}); | ||||
19 | |||||
20 | is the same as: | ||||
21 | |||||
22 | use DateTime::Format::HTTP; | ||||
23 | use DateTime::Format::Mail; | ||||
24 | use DateTime::Format::IBeat; | ||||
25 | |||||
26 | use DateTime::Format::Builder ( | ||||
27 | parsers => { parse_datetime => [ | ||||
28 | sub { eval { DateTime::Format::HTTP->parse_datetime( $_[1] ) } }, | ||||
29 | sub { eval { DateTime::Format::Mail->parse_datetime( $_[1] ) } }, | ||||
30 | sub { eval { DateTime::Format::IBeat->parse_datetime( $_[1] ) } }, | ||||
31 | ]}); | ||||
32 | |||||
33 | (These two pieces of code can both be found in the test | ||||
34 | suite; one as F<quick.t>, the other as F<fall.t>.) | ||||
35 | |||||
36 | =head1 DESCRIPTION | ||||
37 | |||||
38 | C<Quick> adds a parser that allows some shortcuts when | ||||
39 | writing fairly standard and mundane calls to other | ||||
40 | formatting modules. | ||||
41 | |||||
42 | =head1 SPECIFICATION | ||||
43 | |||||
44 | C<Quick> has two keys, one optional. | ||||
45 | |||||
46 | The C<Quick> keyword should have an argument of either an | ||||
47 | object or a class name. If it's a class name then the class | ||||
48 | is C<use>d. | ||||
49 | |||||
50 | The C<method> keyword is optional with a default of | ||||
51 | C<parse_datetime>. It's either name of the method to invoke | ||||
52 | on the object, or a reference to a piece of code. | ||||
53 | |||||
54 | In any case, the resultant code ends up looking like: | ||||
55 | |||||
56 | my $rv = $Quick->$method( $date ); | ||||
57 | |||||
58 | =cut | ||||

64 | type => SCALAR|OBJECT, | ||||
65 | callbacks => { | ||||

67 | (ref $_[0]) or ( $_[0] =~ /^\w+[:'\w+]*\w+/ ) | ||||
