BeamMeta is a library to programmatically get information related to BEAM languages.

Currently Elixir and Erlang/OTP are supported. More languages will be added if there's interest.

The library is divided into the following namespaces:

Provides compatibility between Elixir and Erlang/OTP versions.

The Compatibility.OtpElixir submodule has functions for returning the compatibility table, Elixir and OTP releases, and also the compatible?/2 helper than tells you whether and OTP and an Elixir release are compatible.

Provides information related to releases such as published versions, release condidates, latest Elixir version, etc.

The Release submodule provides guards such as is_elixir_version/1 or is_otp_version/1 amongst others.

• BeamMeta.Release.Elixir provides functions such as:

  • latest_version/0
  • final_releases/0
  • prereleases/0
  • release_data/0 which lists all the information in the JSON file provided by the BeamLangsMetaData in a nicely formatted structure;
  • release_data/2 which accepts a t:Version.requirement/0 allowing you to filter the return values.

• BeamMeta.Release.Otp provides functions such as:

  • latest_version/0
  • final_releases/0
  • release_data/0 which lists all the information in the JSON file provided by the BeamLangsMetaData in a nicely formatted structure;
  • release_data/2 which accepts a t:Version.requirement/0 allowing you to filter the return values.

Additionally, there is a sister library called BeamLangsMetaData which contains the up-to-date data and the one on which this library builds on such as the compatibility tables, and release information. The source code can be found at: https://github.com/eksperimental/beam_langs_meta_data

Due to the nature of the project and since we have not reached v1.0 yet, only the latest v0.MINOR version will be update with the latest meta-data. Older packages will be retired and you will get a warning when using them indicating that you need to update your library.

Packages are regularly updated. All published packages can be found on Hex: https://hex.pm/packages/beam_meta

Online documentation can be found at https://hexdocs.pm/beam_meta

The package can be installed by adding beam_meta to your list of dependencies in mix.exs:

def deps do
  [
    {:beam_meta, "~> 0.2.1"},
  ]
end

Feel free to open up an issue https://github.com/eksperimental/beam_meta/issues with your request.

Run git clone install the repository locally. You can run the following tasks by running:

• mix setup
• mix validate
• mix all

Run tests by executing: mix test

1. Automatic package publishing on every OTP and Elixir new release.
2. Detect update if the release data gets updated. This feature depends on BeamLangsMetaData, but it is planned to be included.
