6 Test::CPAN::Meta::JSON::Version - Validate CPAN META data against the
7 specification
8
10 use Test::CPAN::Meta::JSON::Version;
11
13 This module was written to ensure that a META.json file, provided with
14 a standard distribution uploaded to CPAN, meets the specifications that
15 are slowly being introduced to module uploads, via the use of
16 ExtUtils::MakeMaker, Module::Build and Module::Install.
17 This module is meant to be used together with Test::CPAN::Meta::JSON,
19 however the code is self contained enough that you can access it
20 directly.
21 See CPAN::Meta for further details of the CPAN Meta Specification.
23
25 Validation of META.json data against the CPAN Meta Specification.
26
28 • new( data => $data [, spec => $version] )
29 The constructor must be passed a valid data structure.
31 Optionally you may also provide a specification version. This
33 version is then use to ensure that the given data structure meets
34 the respective specification definition. If no version is provided
35 the module will attempt to deduce the appropriate specification
36 version from the data structure itself.
37
39 Main Methods
40 • parse()
41 Using the given data structure provided with the constructor,
43 attempts to parse and validate according to the appropriate
44 specification definition.
45 Returns 1 if any errors found, otherwise returns 0.
47 • errors()
49 Returns a list of the errors found during parsing.
51 Check Methods
53 • check_map($spec,$data)
54 Checks whether a map (or hash) part of the data structure conforms
56 to the appropriate specification definition.
57 • check_lazylist($spec,$data)
59 If it's a string, make it into a list and check the list
61 • check_list($spec,$data)
63 Checks whether a list (or array) part of the data structure
65 conforms to the appropriate specification definition.
66 Validator Methods
68 • url($self,$key,$value)
69 Validates that a given value is in an acceptable URL format
71 • urlspec($self,$key,$value)
73 Validates that the URL to a META.yml specification is a known one.
75 • string_or_undef($self,$key,$value)
77 Validates that the value is either a string or an undef value. Bit
79 of a catchall function for parts of the data structure that are
80 completely user defined.
81 • string($self,$key,$value)
83 Validates that a string exists for the given key.
85 • file($self,$key,$value)
87 Validate that a file is passed for the given key. This may be made
89 more thorough in the future. For now it acts like \&string.
90 • exversion($self,$key,$value)
92 Validates a list of versions, e.g. '<= 5, >=2, ==3, !=4, >1, <6,
94 0'.
95 • version($self,$key,$value)
97 Validates a single version string. Versions of the type '5.8.8' and
99 '0.00_00' are both valid. A leading 'v' like 'v1.2.3' is also
100 valid.
101 • boolean($self,$key,$value)
103 Validates for a boolean value. Currently these values are '1', '0',
105 'true', 'false', however the latter 2 may be removed.
106 • license($self,$key,$value)
108 Validates that a value is given for the license. Returns 1 if an
110 known license type, or 2 if a value is given but the license type
111 is not a recommended one.
112 • resource($self,$key,$value)
114 Validates that the given key is in CamelCase, to indicate a user
116 defined keyword.
117 • keyword($self,$key,$value)
119 Validates that key is in an acceptable format for the META.yml
121 specification, i.e. any in the character class [-_a-z].
122 For user defined keys, although not explicitly stated in the
124 specifications (v1.0 - v1.4), the convention is to precede the key
125 with a pattern matching qr{\Ax_}i. Following this any character
126 from the character class [-_a-zA-Z] can be used. This clarification
127 has been added to v2.0 of the specification.
128 • identifier($self,$key,$value)
130 Validates that key is in an acceptable format for the META.yml
132 specification, for an identifier, i.e. any that matches the regular
133 expression qr/[a-z][a-z_]/i.
134 • module($self,$key,$value)
136 Validates that a given key is in an acceptable module name format,
138 e.g. 'Test::CPAN::Meta::JSON::Version'.
139 • release_status($self,$key,$value)
141 Validates that the value for 'release_status' is set appropriately
143 for one of 'stable', 'testing' or 'unstable'.
144 • custom_1($self,$key,$value)
146 Validates custom keys based on camelcase only.
148 • custom_2($self,$key,$value)
150 Validates custom keys based on user defined (i.e. /^[xX]_/) only.
152 • phase($self,$key,$value)
154 Validates for a legal phase of a pre-requisite map.
156 • relation($self,$key,$value)
158 Validates for a legal relation, within a phase, of a pre-requisite
160 map.
161 • anything($self,$key,$value)
163 Usually reserved for user defined structures, allowing them to be
165 considered valid without a need for a specification definition for
166 the structure.
