Alien::Build::Plugin::Download::GitHub - Alien::Build plugin to download from GitHub
version 0.10
use alienfile;

plugin 'Download::GitHub' => (
github_user => 'PerlAlien',
github_repo => 'dontpanic',
);
};
This plugin will download releases from GitHub. It is generally preferred over Alien::Build::Plugin::Download::Git for packages that are released on GitHub, as it has much fewer dependencies and is more reliable.
The GitHub user or org that owns the repository. This property is required.
The GitHub repository name. This property is required.
[deprecated: use the asset* properties instead]
Defaulting to false, this option designates whether to include the assets of releases in the list of candidates for download. This should be one of three types of values:
The full list of assets will be included in the list of candidates.
No assets will be included in the list of candidates.
If a regular expression is provided, this will include assets that match by name.
Boolean value for those repositories that do not upgrade their tags to releases. There are two different endpoints. One for releases and one for simple tags. The default is to interrogate the former for downloads. Passing a true value for "tags_only" interrogates the latter for downloads.
Regular expression that can be used to extract a version from a GitHub tag. The default ( qr/^v?(.*)$/ ) is reasonable for many GitHub repositories.
How to sort candidates for selection. This should be one of three types of values:
This will be used as the prefer hook.
Don't set any preference at all. The order returned from GitHub will be used if no other prefer plugins are specified. This may be reasonable for at least some GitHub repositories. This is the default.
Download from assets instead of via tag. This option is incompatible with tags_only.
Regular expression which the asset name should match. The default is qr/\.tar\.gz$/.
The format of the asset. This is passed to Alien::Build::Plugin::Extract::Negotiate so any format supported by that is valid.
[version 0.10]
If this is set to none then no extractor will be added. This allows for you to write your own extractor code, or use a non-standard one.
This is an optional code reference which can be used to modify the version. For example, if the release version is prefixed with a v You could do this:
plugin 'Download::GitHub' => (
github_user => 'PerlAlien',
github_repo => 'dontpanic',
asset => 1,
asset_convert_version => sub {
my $version = shift;
$version =~ s/^v//;
$version;
},
);
If one of these environment variables are set, then the GitHub API Personal Access Token (PAT) will be used when connecting to the GitHub API.
For security reasons, the PAT will be removed from the log. Some Fetch plugins (for example the curl plugin) will log HTTP requests headers so this will make sure that your PAT is not displayed in the log.
Setting this to a true value will send additional diagnostics to the log during the indexing phase of the fetch.
This plugin does not support, and will not work if ALIEN_DOWNLOAD_RULE is set to either digest_and_encrypt or digest.
The GitHub API is rate limited. Once you've reach that limit, this plugin will be inoperative for a period of time until the limits reset. When using the GitHub API unauthenticated the limit is especially low. This is usually not a problem when used in production where you only need to use the API once for each Alien, but it can become a problem when testing an Alien that uses this plugin in CI or via cpantesters. In this situation you can set the ALIEN_BUILD_GITHUB_TOKEN environment variable (or commonly used but unofficial GITHUB_TOKEN or GITHUB_PAT), and this plugin will use that in making API requests. If you are using GitHub Actions for CI, then you can use the secrets.GITHUB_TOKEN macro to get a PAT.
If you do this it is recommended that you make some precautions where possible:
Create a PAT with the bare minimum access permissions. Consider creating a separate GitHub account without access to anything, and use it to generate the PAT.
The PAT is only needed (if it is needed at all) during the build stage of a share install. If you are doing this in GitHub Actions you can just set the environment variable for that stage:
perl Makefile.PL
env ALIEN_BUILD_GITHUB_TOKEN=${{ secrets.GITHUB_TOKEN }} make
make test
Or if you are using Dist::Zilla
dzil listdeps --missing | cpanm -n
env ALIEN_BUILD_GITHUB_TOKEN=${{ secrets.GITHUB_TOKEN }} dzil test
