ErlT Examples

This directory includes several Erlang-style applications written in ErlT.

• elm_core -- a subset of Elm's standard library ported to ErlT
• erltodo -- this example shows usage of ErlT structs and enums in a runnable app
• typed_lib -- straightforward port of Erlang's gb_trees library to ErlT
• advent_of_code -- Advent of Code 2020 solutions in ErlT

Working on ErlT code

Edit ErlT code in <app-name>/src/*.erlt. The directory structure is the same as for Erlang.

Use normal rebar3 workflow from this directory: rebar3 compile to compile examples, rebar3 shell to interact with example apps.

Make a new ErlT app

In this directory:

rebar3 new erlt <app-name>

Example session

rebar3 new erlt test_app

% rebar3 shell
