Ale and elixir-tools

[Bastes]

Hello,

I'm not sure I'm in the right section but as a happy ALE user for most of my lsp/linting uses, I've found elixir-ls wanting when working on different versions of Elixir, as it downloads and compiles a one-size-fits-all version of elixir-ls that may not be compatible with every elixir version installed. For example, I'm currently working with my team on an elixir v1.11.4 which plays well with the version of elixir-ls installed (0.12, ironically the last one supporting elixir v1.11), but I've got other projects on v1.17 which is not playing well with elixir-ls v0.12.0.

I've since toyed with elixir-tools which comes with another policy: compiling elixir-ls in the relative .elixir_ls subdirectory of a project so as to pick a version that works with the version of elixir of that project. This seems the way to go for someone working with multiple elixir versions.

So, here's my question: is there a way to tell ALE to go searching for a language_server.sh relative to the project? So far I tried to give a relative path to ALE and it wasn't able to start the server so I thought I'd ask, and if that is not possible, maybe suggest this feature? I might even help if that's not above my abilities.

Anyways, great plugin :) always using it.

There does not seem to be a way to do this now. Modifying the ale_linters#elixir#elixir_ls#GetExecutable() function to search first for the executable within the project root .elixir_ls path and then fallback to the global one would do. There is a helper function that could be used for this ale#path#FindNearestExecutable().

Thank you for your reply :) I'll be looking into it, I'm not a very strong vim scripter but if I can I'll be testing and ideally providing a PR.
