OTP example with LFE : Echo

Both examplifies building a very simple OTP application with LFE and compiling it with Mix.

The mix compiler for LFE is used (https://github.com/meddle0x53/mix_lfe). Can be used as a template for a similar project.

Running the example

Has to be set up, using the mix_lfe plugin for Mix. It can be installed like this:

mix archive.install https://github.com/meddle0x53/mix_lfe_new/releases/download/v0.2.0/mix_lfe_new-0.2.0.ez

Now the project can be downloaded, set up and compilet like this:

git clone https://github.com/meddle0x53/echo
cd echo

mix lfe.setup
mix compile

This will compile the LFE code and will generate the app file. It can be tested with mix:

iex -S mix

Now the application will be running and can be accessed through Elixir:

"test" = :"echo-worker".echo("test") # Returns what was passed to it.
1 = :"echo-worker".count() # Returns how many times the :"echo-worker".echo/1 function was called.

It can be used in LFE too:

./deps/lfe/bin/lfe -pa _build/dev/lib/*/ebin

And now:

> (application:ensure_all_started 'echo)
#(ok (echo))

> (echo-worker:echo #"bla")
#"bla"
> (echo-worker:count)
1

> (echo-worker:echo #"boo")
#"boo"
> (echo-worker:count)
2

It has a simple test doing similar checks to the above ones. Run it with:

mix lfe.test
