NAME

       Pandoc::Release - get pandoc releases from GitHub

SYNOPSIS

       From command line:

         # print latest release name
         perl -MPandoc::Release -E 'say latest->{name}'

         # download latest release unless already in ~/.pandoc/bin
         perl -MPandoc::Release -E 'latest->download'

         # download specific release and create symlink ~/.pandoc/bin/pandoc
         perl -MPandoc::Release -E 'get("2.7.3")->download->symlink'

       In Perl code:

         use Pandoc::Release;

         my $release = get('2.1.3');   # get a specific release
         my $latest = latest;          # get a latest release

         # get multiple releases
         my @releases = list( since => '2.0', verbose => 1 );
         foreach my $release (@releases) {

             # print version number
             say $release->{tag_name};

             # download Debian package and executable
             $release->download( dir => './deb', bin => './bin' );
         }

         # download executable and use as temporary Pandoc object:
         my $pandoc = get('2.1.3)->download( bin => './bin' );

DESCRIPTION

       This utility module fetches information about pandoc releases via GitHub API.  On Debian-
       bases systems, this module can update and switch locally installed pandoc versions if you
       add directory "~/.pandoc/bin" to your $PATH.

       See pandoc-version for a command line script that makes use of this module.

FUNCTIONS

       All functions are exported by default.

   get( $version, %options )
       Get a specific release by its version or die if the given version does not exist. Returns
       data as returned by GitHub releases API:
       <https://developer.github.com/v3/repos/releases/#get-a-release-by-tag-name>.

   list( %options )
       Get a list of all pandoc releases, optionally "since" some version or within a version
       "range" such as "!=1.16, <=1.17" or "==2.1.2". See "Version Ranges" in CPAN::Meta::Spec
       for possible values. Option "verbose" will print URLs before each request. Option "limit"
       limits the maximum number of releases to be returned.

   latest( %options )
       Get the latest release, optionally "since" some version or within a version "range".
       Equivalent to method "list" with option "limit => 1".

METHODS

   download( %options )
       Download the Debian release file for some architecture (e.g. "amd64") Pandoc executables
       is then extracted to directory "bin" named by pandoc version number (e.g. "pandoc-2.1.2").
       Skips downloading if an executable of this name is already found there.  Returns a Pandoc
       instance if "bin" is not false or Pandoc::Version otherwise. Additional options:

       dir Where to download release files to. A temporary directory is used by default.

       arch
           System architecture, detected with "dpkg --print-architecture" by default.

       bin Where to extract pandoc binary to. By default set to "~/.pandoc/bin" on Unix (see
           Pandoc function "pandoc_data_dir").  Extraction of executables can be disabled by
           setting "bin" to a false value.

       symlink
           Create a symlink to the executable. This is just a shortcut for calling function
           "symlink" of Pandoc:

             $release->download( verbose => $v )->symlink( $l, verbose => $v )
             $release->download( verbose => $v, symlink => $l )   # equivalent

COMMON OPTIONS

       verbose
           Print what's going on (disabled by default).

       token
           GitHub token <https://github.com/settings/tokens> to avoid rate limiting.
