NAME

6       Module::Install::PAR - Module::Install Support for PAR::Dist packages
7

SYNOPSIS

9       To offer your users the possibility to install binaries if we cannot
10       compile an XS version of the module, you could use this simplistic
11       stub:
12
13           use inc::Module::Install;
14
15           name            'Foo';
16           all_from        'lib/Foo.pm';
17
18           # Which CPAN directory do we fetch binaries from?
19           par_base        'SMUELLER';
20
21           unless ( can_xs ) {
22               my $okay = extract_par( fetch_par );
23               if (not $okay) {
24                   die "No compiler and no binary package found. Aborting.\n";
25               }
26           }
27
28           WriteAll;

DESCRIPTION

31       This module adds a couple of directives to Module::Install related to
32       installing and creating PAR::Dist distributions.
33
34   par_base
35       This directive sets the CPAN ID from whose CPAN directory to fetch
36       binaries from. For example, you can choose to download binaries from
37       http://www.cpan.org/authors/id/S/SM/SMUELLER/ or its ftp counterpart by
38       writing:
39
40         par_base 'SMUELLER';
41
42       By default, the name of the file to fetch is generated from the
43       distribution name, its version, your platform name and your perl
44       version concatenated with dashes.
45
46       The directive, however, takes an optional second argument which
47       specifies the name of the file to fetch.  (Though "par_base" does not
48       fetch files itself, see below.)
49
50         par_base 'SMUELLER', 'foo';
51
52       Once "fetch_par" is called, the file 'foo' will be downloaded from
53       SMUELLER's CPAN directory. (It doesn't exist.)
54
55       The second argument could be used to fetch platform-agnostic binaries:
56
57         par_base 'SMUELLER', "Some-Distribution-0.01.par";
58
59       (Documentation TODO: Use the previously defined distribution name and
60       version in example.)
61
62   fetch_par
63       Fetches the .par file previously referenced in the documentation of the
64       "par_base" directive.
65
66       "fetch_par" can be used without arguments given the "par_base"
67       directive was used before. It will return the name of the file it
68       fetched.
69
70       If the first argument is an URL or a CPAN user ID, the file is fetched
71       from that directory unless an URL has been previously set.  (Read that
72       again.)
73
74       If the second argument is a file name it is used as the name of the
75       file to download.
76
77       If the file could not be fetched, a suitable error message about no
78       package being available, yada yada yada, is printed.  You can turn this
79       off by specifying a true third argument.
80
81         # Try to fetch the package (see par_base) but
82         # don't be verbose about failures
83         my $file = fetch_par('', '', undef);
84
85   extract_par
86       Takes the name of a PAR::Dist archive file as first argument. The
87       'blib/' directory of this archive is extracted and the 'pm_to_blib' is
88       created.
89
90       Typical shorthand usage:
91
92         extract_par( fetch_par ) or die "Could not install PAR::Dist archive.";
93
94   make_par
95       This directive requires PAR::Dist (version 0.03 or up) on your system.
96       (And checks that it is available before continuing.)
97
98       Creates a PAR::Dist archive from the 'blib/' subdirectory.
99
100       First argument must be the name of the PAR::Dist archive to create.
101
102       If your Makefile.PL has a "par_base" directive, the "make par" make
103       target will be available. It uses this "make_par" directive internally,
104       so on your development system, you can do this to create a .par binary
105       archive for your platform:
106
107         perl Makefile.PL
108         make
109         make par
