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'

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. It requires at least Perl 5.14 or HTTP::Tiny and JSON::PP installed.

FUNCTIONS

All functions are exported by default.

get( $version [, verbose => 0|1 ] )

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( ... )

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( ... )

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

METHODS

download( [ dir => $dir ] [ arch => $arch ] [ bin => $bin ] [ verbose => 0|1] )

Download the Debian release file for some architecture (e.g. amd64) to directory dir, unless already there. By default architecture is determined via calling dpkg and download directory is a newly created temporary directory. Pandoc executables is then extracted to directory bin named by pandoc version number (e.g. pandoc-2.1.2). The default bin directory is ~/.pandoc/bin on Unix (see Pandoc function pandoc_data_dir):

$release->download( bin => pandoc_data_dir('bin') );
$release->download;   # equivalent

Extraction of executables can be disabled by setting bin to a false value. Returns a Pandoc instance if bin is not false or Pandoc::Version otherwise.
