NAME

Alien::Meson - Find or build meson build tool

SYNOPSIS

Command line tool:

use Alien::Meson;
use Env qw( @PATH );

unshift @PATH, Alien::Meson->bin_dir;
system "@{[ Alien::Meson->exe ]}";

Use in alienfile:

share {
  requires 'Alien::Meson';
  requires 'Alien::Ninja';
  # ...
  my $build_dir = '_build';
  build [
    sub {
      my $build = shift;
      Alien::Build::CommandSequence->new([
        Alien::Meson->exe, 'setup',
          '--prefix=%{.install.prefix}',
          $build_dir,
      ])->execute($build);
    },
    [ '%{ninja}', qw(-C), $build_dir, "test" ],
    [ '%{ninja}', qw(-C), $build_dir, 'install' ],
  ];
}

DESCRIPTION

This distribution provides meson so that it can be used by other Perl distributions that are on CPAN. It does this by first trying to detect an existing install of meson on your system. If found it will use that. If it cannot be found, the source code will be downloaded from the internet and it will be installed in a private share location for the use of other modules.

METHODS

exe

Alien::Meson->exe

Returns the command name for running meson.

_apply_destdir_prefix_hack

use alienfile;

eval {
  require Alien::Meson;
  Alien::Meson->_apply_destdir_prefix_hack;
};

share { ... }

Applies a hack to fix how the DESTDIR and prefix are joined to follow the approach that Meson takes. See issue at PerlAlien/Alien-Build#407 for more information.

WARNING: This is a hack. It is not expected to work long-term and if a better solution is possible, it will be deprecated then removed.

HELPERS

meson

%{meson}

WARNING: This interpolation is deprecated. This will be removed in a future version as some share installs of Meson are not callable as a single executable (they need to be prefixed with the Python interpreter). Instead use Alien::Meson->exe directly.

Returns 'meson', 'meson.py', or appropriate command for platform.
