Type of Package

Binary package

Use as Dependency

Binary packages can be set as runtime or build time dependencies. See Defining your dependencies for more information.

To add core/elixir as a dependency, you can add one of the following to your plan file.

Buildtime Dependency

pkg_build_deps=(core/elixir)

Runtime dependency

pkg_deps=(core/elixir)

Use as Tool

Installation

To install this plan, you should run the following commands to first install, and then link the binaries this plan creates.

hab pkg install core/elixir --binlink

will add the following binaries to the PATH:

For example:

$ hab pkg install core/elixir --binlink

Additional Steps

Before using core/elixir stand alone binaries, the runtime environment requires erlang on the $PATH and locale set to UTF-8 encoding. Fortunately habitat takes care of all this: Preceed all binary commands with hab pkg exec core/elixir and the binaries will work as expected.

For example, calling mix with the above prefix returns a successful response:

[8][default:/src/elixir:127]# hab pkg exec core/elixir mix --version
Erlang/OTP 21 [erts-10.3] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe]

Mix 1.10.0 (compiled with Erlang/OTP 21)
[9][default:/src/elixir:0]#

However, running mix without the prefix means the erlang executable is included in the runtime environment and an error is returned like

[7][default:/src/elixir:0]# mix --version
/bin/elixir: line 230: exec: erl: not found
