Hi
After gleam v0.33 there this kind of warning being generated for mix_gleam based projects.
Is there are a way to disable these warnings. Lot of warnings are being generated.
Event though those dependencies are present in the mix.exs.
┌─ ./test/gleam_tests/utils/timeslots_test.gleam:1:1
│
1 │ import gleam/option
│ ^^^^^^^^^^^^^^^^^^^
The module gleam/option
is being imported, but gleam_stdlib
, the
package it belongs to, is not a direct dependency of your package.
In a future version of Gleam this may become a compile error.
Run this command to add it to your dependencies:
gleam add gleam_stdlib`
`
Please advise.

I'm encountering an issue when trying to generate an ecto migration.
When I add the Gleam compiler to the compilers
list in mix.exs
file and try to run mix ecto.gen.migration <migration_name>
, I receive this error:
** (Mix) Unknown dependency <migration_name> for environment <my_mix_env_value>
Steps to Reproduce:
:gleam
compiler to the compilers
list in the mix.exs
file.mix ecto.gen.migration
.Expected Behavior:
The migration should be generated normally without any errors.
Environment:

In this gif I first tried using the 'compilers' key. Then, I tried again with compilers

Hi! Thank you for Gleam!
Environment:
VSCode: 1.47.3
ElixirLS extension: 0.5.0 ()
mix_gleam: 0.1.0
Elixir: 1.10.4
Erlang/OTP: 23
Steps to reproduce:
Open the basic_project in this repo in VSCode.
ElixirLS goes into a compile loop. If I remove :gleam
from Project compilers in mix.exs then it completes.
The ElixirLS output loop looks like this:
[Info - 6:26:06 PM] Compile took 1667 milliseconds
MIX_ENV: test
MIX_TARGET:

[Info - 6:26:08 PM] [ElixirLS WorkspaceSymbols] 0 callbacks added to index
[Info - 6:26:08 PM] Compile took 1176 milliseconds
Disabling Dialyzer makes no difference.
With verbose ElixirLS logging I'm seeing examples of the below right after compilation:
[Trace - 9:14:12 PM] Sending notification 'workspace/didChangeWatchedFiles'.
Params: {
"changes": [
{
"uri": "file:///Users/rala/Projects/elixir/mix_gleam/test_projects/basic_project/gen/src/basic_project.erl",
"type": 2
}
]
}
This leads me to believe that something is touching the gleam compilation output file afterwards, which triggers a new round of compilation.
I'm unsure whether this is an issue with the gleam compiler, mix_gleam, VSCode-ElixirLS or ElixirLS. With some guidance I may be able to help out more (but my spare time is limited due to my current family situation).
Prerequisite: I have installed the latest version (0.6.1) of mix_gleam
.
My .tool-versions
:
erlang 26.0.2
elixir 1.15.4-otp-26
Run mix test
:
** (Mix) The task "compile.gleam" could not be found. Did you mean "compile.erlang"?
When I change the Elixir version to 1.14.5-otp-26
, everything works fine, including the function calling gleam_stdlib
in IEx.
Honestly, I've no idea if this is a priority or perhaps a mistake on my part or anything. I continue to tell myself that I can choose to not learn rebar3 and just use gleam through mix but that might not be the case.

I'm very happy for this to be closed but I thought I'd share it in case it is useful to fix for some reason. I realise these libraries are a bit in flux at the moment and the mix is not a primarily supported build tool.
Doing the same with gleam new
and rebar3.config doesn't seem to have a problem.

When using gleam v0.25.0 the erlang code generated by gleam is not compiled later in the compilation stages when using mix tasks. As a result gleam modules are not available at runtime. I suspect it is caused by the change of output directory for the erlang code produced by gleam gleam-lang/gleam@b35ecd3#diff-bab1783d97666c826f55924d7d1dc3f73c005ddd445b14c77ce2e52880fcdb64R5.
Changing :erlc_paths
in mix.exs
to ["build/dev/erlang/#{@app}/_gleam_artefacts"]
works as a fix for modules of current application but the dependencies are still not available.
MixGleam
should use precompiled Erlang modules when Gleam projects provide them.
Other dependencies that have Gleam in them cannot be compiled until this package has been compiled.
Those other packages might not rely on mix_gleam if they are built in rebar.
After integrating Gleam in an Elixir codebase, I found that elixir-ls never stops to compile the project. It can be easily reproduced with https://github.com/midas-framework/elixir_with_gleam.
elixir 1.11.3-otp-23
erlang 23.1.1
gleam 0.9.0
But I also tested it with different permutations of Gleam 0.13.2, Erlang 22 and Elixir 1.10 with the same result.
It may be a side effect that every Gleam file is recompiled when starting a mix project (the stdlib included). Executing mix compile
2 times in a row without modification triggers a full compile of the Elixir project.
$ ls build/dev/erlang/hello/build/

$ mkdir src/hey && mv src/hello.gleam src/hey

This can be resolved by re-fetching deps and compiling directly within the sub-project:

Should gleam.toml contain the same deps as mix.exs in regards to gleam so that gleam test, lsp and so on work while mix compile also works? Should the docs inform about this?
