Add Gleam version

[lpil]

Also usable from other BEAM languages such as Erlang and Elixir.

[keith-turner]

@lpil I will look at this in the next few days

[keith-turner]

@lpil I tried building this and saw the following. I downloaded gleam-v0.10.0-linux-amd64.tar.gz from the github releases page.

$ gleam build

error: Unknown import
  ┌─ /home/AzureUser/git/ecoji/src/ecoji.gleam:2:8
  │
2 │ import gleam/bit_builder.{BitBuilder}
  │        ^^^^^^^^^^^^^^^^^ did you mean `ecoji/table`?

The module `ecoji` is trying to import the module `gleam/bit_builder`,
but it cannot be found.

Hi Keith! You'll need to use the rebar3 build tool to compile the project rather than using the raw compiler. If you have it installed running rebar3 eunit will run the tests and rebar3 shell will run an Erlang shell for the project.

There's language installation instructions on the website: https://gleam.run/getting-started/index.html

@lpil now I see the following error (I know nothing about erlang)

It looks like your Erlang installation is missing the eunit libraries. If you've installed Erlang using your operating system package manager there may be additional packages that need to be installed to be ready for development.

@lpil I am trying to run this on Ubuntu 18.04. I got a bit further after reading your comment I looked for other things to install and found apt install erlang-dev. Still can not get to the point of running. Seeing the following error.

[lpil]

That's another eunit related library that is missing. I'm afraid I don't know what packages would be required, I typically build Erlang from source

[lpil]

Any joy here @keith-turner ?

[lpil]

Hi @keith-turner , can we merge this? Perhaps the tests running on CI could be evidence of it working? Or we could test inside a docker container?

[lpil]

Hello @keith-turner , any progress here?

[keith-turner]

Hello @keith-turner , any progress here?

@lpil no I have never tried to build and run it again since when I was unable to run it before.

[lpil]

Is running CI sufficient evidence? Alternatively are you able to run docker containers on your machine? I could provide either.

[lpil]

A third option is that if you install Erlang using the .deb supplied by Erlang Solutions that will have all the libraries required.

Forth there seems to be an erlang-eunit package on Ubuntu, though I can't vouch for the suitability.

[lpil]

Hello! Could we get this merged please? 🙏

[lpil]

Hi @keith-turner, I've rebased this to resolve the merge conflict. It would be great it if it could be merged!

If you have Erlang and Gleam installed you can use the Gleam build tool to run the tests, etc.
