9 $ cpm install Module
10
12 cpm is yet another CPAN client (like cpan, cpanp, and cpanm), which is
13 fast!
14
15 How to install cpm
16 From CPAN:
17
18 $ cpanm -nq App::cpm
19
20 Or, download a self-contained cpm:
21
22 $ curl -sL --compressed https://git.io/cpm > cpm
23 $ chmod +x cpm
24 $ ./cpm --version
25
26 # you can even install modules without installing cpm
27 $ curl -sL --compressed https://git.io/cpm | perl - install Plack
28
29 First step
30 $ cpm install Plack
31
32 This command installs Plack into "./local", and you can use it by
33
34 $ perl -I$PWD/local/lib/perl5 -MPlack -E 'say Plack->VERSION'
35
36 If you want to install modules into current INC instead of "./local",
37 then use "--global/-g" option.
38
39 $ cpm install --global Plack
40
41 By default, cpm outputs only "DONE install Module" things. If you want
42 more verbose messages, use "--verbose/-v" option.
43
44 $ cpm install --verbose Plack
45
46 Second step
47 cpm can handle version range notation like cpanm. Let's see some
48 examples.
49
50 $ cpm install Plack~'> 1.000, <= 2.000'
51 $ cpm install Plack~'== 1.0030'
52 $ cpm install Plack@1.0030 # this is an alias of ~'== 1.0030'
53
54 cpm can install dev releases (TRIAL releases).
55
56 $ cpm install Moose@dev
57
58 # if you prefer dev releases for not only Moose,
59 # but also its dependencies, then use global --dev option
60 $ cpm install --dev Moose
61
62 And cpm can install modules from git repositories directly.
63
64 $ cpm install git://github.com/skaji/Carl.git
65
66 cpanfile and dist/url/mirror/git syntax
67 If you omit arguments, and there exists "cpanfile" in the current
68 directory, then cpm loads modules from cpanfile, and install them
69
70 $ cat cpanfile
71 requires 'Moose', '2.000';
72 requires 'Plack', '> 1.000, <= 2.000';
73 $ cpm install
74
75 If you have "cpanfile.snapshot", then cpm tries to resolve distribution
76 names from it
77
78 $ cpm install -v
79 30186 DONE resolve (0.001sec) Plack -> Plack-1.0030 (from Snapshot)
80 ...
81
82 cpm supports dist/url/mirror syntax in cpanfile just like cpanminus:
83
84 requires 'Path::Class', 0.26,
85 dist => "KWILLIAMS/Path-Class-0.26.tar.gz";
86
87 # use dist + mirror
88 requires 'Cookie::Baker',
89 dist => "KAZEBURO/Cookie-Baker-0.08.tar.gz",
90 mirror => "http://cpan.cpantesters.org/";
91
92 # use the full URL
93 requires 'Try::Tiny', 0.28,
94 url => "http://backpan.perl.org/authors/id/E/ET/ETHER/Try-Tiny-0.28.tar.gz";
95
96 And yes, this is an experimental and fun part! cpm also supports git
97 syntax in cpanfile.
98
99 requires 'Carl', git => 'git://github.com/skaji/Carl.git';
100 requires 'App::cpm', git => 'https://login:password@github.com/skaji/cpm.git';
101 requires 'Perl::PrereqDistributionGatherer',
102 git => 'https://github.com/skaji/Perl-PrereqDistributionGatherer',
103 ref => '3850305'; # ref can be revision/branch/tag
104
105 Please note that to support git syntax in cpanfile wholly, there are
106 several TODOs.
107
108 Darkpan integration
109 There are CPAN modules that create darkpans (minicpan, CPAN mirror)
110 such as CPAN::Mini, OrePAN2, Pinto.
111
112 Such darkpans store distribution tarballs in
113
114 DARKPAN/authors/id/A/AU/AUTHOR/Module-0.01.tar.gz
115
116 and create the de facto standard index file "02packages.details.txt.gz"
117 in
118
119 DARKPAN/modules/02packages.details.txt.gz
120
121 If you want to use cpm against such darkpans, change the cpm resolver
122 by "--resolver/-r" option:
123
124 $ cpm install --resolver 02packages,http://example.com/darkpan Module
125 $ cpm install --resolver 02packages,file::///path/to/darkpan Module
126
127 Sometimes, your darkpan is not whole CPAN mirror, but partial, so some
128 modules are missing in it. Then append "--resolver metadb" option to
129 fall back to normal MetaDB resolver:
130
131 $ cpm install \
132 --resolver 02packages,http://example.com/darkpan \
133 --resolver metadb \
134 Module
