Update: This was very much an initial exploration. There is now an official project with a mix_gleam plugin. Please check that out!

Nice article. This has allowed me to add a bit of gleam to my existing Elixir project.
I found that if I want to use gleam libraries I need to put them in a
rebar.configin the project root so that the project compiles, but then also add them to themix.exsso that they are available at run time. Do you have any ideas for avoiding this duplication?Thanks for the comment. I'm sorry to say that I've not gone much further on this so I actually can't help you with your issue. I'm excited by Gleam but I'm still trying to figure out how to fit it into my projects.
I asked on the Elixir Forum Gleam thread about further interop between Phoenix, Ecto & Gleam but lpil, the Gleam creator, suggests that this might be quite hard due to Elixir macros. I'm keen to explore more but I haven't found the time.
OK - thanks for the reply! I'll let you know if I find out more myself.
I contributed a fix to Gleam that means it now finds gleam source for dependencies in a mix project github.com/gleam-lang/gleam/pull/596
Also instead of defining your own compiler module an alias will do
aliases: ["compile.gleam": "cmd gleam build"]I put a working example here github.com/midas-framework/elixir_...
Great! Works perfectly. Thanks Peter!
There is now. github.com/gleam-lang/mix_gleam
Which should work even better.
I've also updated the elixir with gleam example
Nice writeup! Would you know if it is possible to register Gleam modules to be accessed using the same naming convention of Elixir? I know that at the end of the day, all module names are just atoms, but mixing the style will make the code base inconsistent, IMO.
Thanks for the question. I don't know too much about the situation, I'm afraid.
I think Gleam modules are compiled to be maximally accessible from Erlang. It has crossed my mind that Gleam could have an output mode that namespaced things for Elixir (I think Elixir modules are just atoms that start with "Elixir." though I'm far from an expert.) I don't think that is planned at the moment though. Might be worth raising. The gleam community has a uses GitHub discussions (github.com/gleam-lang/gleam/discus...) and Discord (discord.com/invite/Fm8Pwmy) for communicating mostly at the moment.
I imagine that if you were to create a library in Gleam and wanted to make it even friendlier for Elixir programmers then you publish some Elixir modules into the bundle that act like a shim to provide Elixir style access to the functions and types.

huh, turns out it's pretty easy to add compilers to Mix.
But I guess the generated erlang files would be in the same directory with this setup.. a proper integration would hide them in
_buildYeah, not that hard at all, eh? :)
Yeah, the Gleam compiler would have to be tweaked so it was at least configurable to target the _build folder instead. The creator of Gleam is interested in that route but is unsure of how best to approach it: github.com/gleam-lang/gleam/issues...
Good one! I like Gleam and watching it since a while. Now I have a good reason to use it :)
Did you use Gleam for some specific problem that would be more difficult to solve using just Elixir?
Thanks for commenting. Honestly, no. I haven't written much in Gleam at all. Given that it targets the BEAM I imagine it will one day be good for similar problems as Elixir. At the moment it is quite young and I struggle to figure out how best to use it. My main interest is that I really enjoy working with Elm as a simple, clear language with a strong static type system and a friendly compiler and to the degree that Gleam has similar goals but targets the Erlang VM I would like to see it succeed.
