# Erlang External Term Format

Glaze optionally supports the [Erlang External Term Format](https://www.erlang.org/doc/apps/erts/erl_ext_dist.html), abbreviated as EETF.

The Glaze CMake provides the option: `glaze_EETF_FORMAT`. Enable this option to link in the require Erlang libraries.

> In the long term the goal is to remove the requirement on the Erlang libraries, but they are required for now.

If you are not using CMake the macro `GLZ_ENABLE_EETF` must be added to utilize Glaze's EETF headers. The `glaze_EETF_FORMAT` will add the `GLZ_ENABLE_EETF` macro if selected.
