SYNOPSIS

13        use alienfile;
14        plugin 'Probe::CommandLine' => (
15          command => 'gzip',
16          args    => [ '--version' ],
17          match   => qr/gzip/,
18          version => qr/gzip ([0-9\.]+)/,
19        );

DESCRIPTION

22       This plugin probes for the existence of the given command line program.
23

PROPERTIES

25   command
26       The name of the command.
27
28   args
29       The arguments to pass to the command.
30
31   secondary
32       If you are using another probe plugin (such as
33       Alien::Build::Plugin::Probe::CBuilder or
34       Alien::Build::Plugin::PkgConfig::Negotiate) to detect the existence of
35       a library, but also need a program to exist, then you should set
36       secondary to a true value.  For example when you need both:
37
38        use alienfile;
39        # requires both liblzma library and xz program
40        plugin 'PkgConfig' => 'liblzma';
41        plugin 'Probe::CommandLine => (
42          command   => 'xz',
43          secondary => 1,
44        );
45
46       When you don't:
47
48        use alienfile;
49        plugin 'Probe::CommandLine' => (
50          command   => 'gzip',
51          secondary => 0, # default
52        );
53
54   match
55       Regular expression for which the program output should match.
56
57   match_stderr
58       Regular expression for which the program standard error should match.
59
60   version
61       Regular expression to parse out the version from the program output.
62       The regular expression should store the version number in $1.
63
64   version_stderr
65       Regular expression to parse out the version from the program standard
66       error.  The regular expression should store the version number in $1.
