Getting Started

If you have Tele installed you'll want to do more than hello_world.

In this section we will show you how to setup an Erlang library and write the code with Tele.

Create A New Project

Use Rebar3 to create a new Erlang project.

rebar3 new lib example

There will be a few files of note. You can read more about rebar.config and src/example.app.src in the Rebar3 docs.

Since we are coding in Tele we can go ahead and delete src/example.erl and make a new tele file in it's place.

rm -f src/example.erl
touch src/example.tl

Inside of src/example.tl make a module like this:

fun add2(x): x + 2

Run tele build. Then start the shell, rebar3 shell.

In the shell we can run our module:

example:add2(4).
=> 6
