ElixisLS in VS Code does not format *.ex, *.exs files

Hi ! Are you running the “Format Command” in VSCode (defaults to alt+shift+f)?

If that isn’t working then try running through the debugging steps: GitHub - elixir-lsp/vscode-elixir-ls: Elixir language support and debugger for VS Code, powered by ElixirLS. · GitHub

I tried with keyboard secuences alt+shift+f.
I also tried with Ctrl+shift+p, then “Format document”

Nothing happens.

View output:

The toggle developer tools output is:

But these electron warnings were there at the start of VS Code, before I tried to format.

As I could not get it work, I created a VSCode Task, to execute “mix format”, and assigned it a keyboard sequence.
So, instead of pressing just Ctrl+S to save my file and format it, I need to press another key sequence after the save. It is not terribly bad. It’s a workaround, until somebody enlightens me.

Best regards,

Hi, I experience the same problem, the format command from VSCode does not trigger mix format. When running mix format from the CLI this goes well.

My Elixir-ls output log looks fine:

What else should I check into?

I’d bounce over to Issues · elixir-lsp/elixir-ls · GitHub to see if there are any similar issues logged (and create one if not).

Beware, that the code is not formatted if there are syntax errors.

FWIW I’ve been having trouble too (formatter.exs seems to not be respected) and rolled back to the previous version, I just haven’t been able to gather enough details to post a helpful issue yet It doesn’t seem related to the existing issue about formatter.exs during compilation, but I need to double check first.

Try ctrl + shift + I. Check File, Preferences, Keyboard shortcuts.
