Alien::Build::Plugin::Probe::CommandLine - Probe for tools or commands already available
use alienfile; plugin 'Probe::CommandLine' => ( command => 'gzip', args => [ '--version' ], match => qr/gzip/, version => qr/gzip ([0-9\.]+)/, );
This plugin probes for the existence of the given command line program.
The name of the command.
The arguments to pass to the command.
If you are using another probe plugin (such as Alien::Build::Plugin::Probe::CBuilder or Alien::Build::Plugin::PkgConfig::Negotiate) to detect the existence of a library, but also need a program to exist, then you should set secondary to a true value. For example when you need both:
use alienfile; # requires both liblzma library and xz program plugin 'PkgConfig' => 'liblzma'; plugin 'Probe::CommandLine => ( command => 'xz', secondary => 1, );
When you don't:
use alienfile; plugin 'Probe::CommandLine' => ( command => 'gzip', secondary => 0, # default );
Regular expression for which the program output should match.
Regular expression to parse out the version from the program output. The regular expression should store the version number in
