Do you have ecto_sql as a direct or indirect dependency? You can check mix.exs or mix.lock.

3

Is this by any chance an umbrella project where this happens?

4

It is not an Umbrella project.

5

Yes, I had ecto_sql in my mix dependencies.

6

I’ve fixed a lot of problems with ElixirLS by deleting the .elixir_ls folder as described here. They usually happen after ElixirLS gets updated.

Can I stop the auto-update of the ElixirLS extension, if that may resolve the issue. Or do you know which version is the stable one?

8

I’m experiencing the same issue. This seems to have started with a recent update. It bites me pretty hard after switching branches with different deps. Of course, a simple rm -rf ./.elixir_ls fixes this issue. But the 3-5 minutes to rebuild the project for the “special” ElixirLS build directory is a drag.

It is definitely a hinderance. But it is something I’ve learned to live with for the immense productivity boost I get with this tool.

Aside: I hate that auto-complete stopped working with underscores.

Example:

In a guard, I used to be able to type isbin, hit tab and it would autocomplete is_binary. Now after typing is, if I don’t specify _, I lose all guidance. That is also a drag :slight_smile:

That was changed in: Remove keywords from completions by axelson · Pull Request #259 · elixir-lsp/elixir-ls · GitHub

The reason was to avoid some very bad completions, such as:
82835207-10d99c80-9e5f-11ea-82b1-b745707ecf74

We would accept a PR that makes the isIncomplete: true setting configurable.

Is there something particular with umbrella projects? I’m currently working on an umbrella application and I get that same output message "ElixirLS has crashed" at least 20 times a day, it is driving me nuts.

Yes. The formatter is not picking the correct project root, and that causes issues like this.

12

So I’m supposed to change the project direction for the extension’s configuration every time I work on different umbrellas?

13

Under most circumstances it should be set to empty string

This comment save my times. Thanks you so much @factoryd
