Formatter hangs on VSCode 1.42.0 about vscode-elixir-ls HOT 26 CLOSED

@axelson I don’t remember for sure, but it should be one of these two (probably the second one):

• https://marketplace.visualstudio.com/items?itemName=saratravi.elixir-formatter

• https://marketplace.visualstudio.com/items?itemName=sammkj.vscode-elixir-formatter

It was a very old one, I don’t remember when I’ve installed it. I’ve just found to have it, I removed it, and everything worked as expected.

from vscode-elixir-ls.

Okay, well if you figure it out please report back! Best of luck :)

from vscode-elixir-ls.

I had this same issue and realized it was because I had set my default formatter to Prettier in my user settings. So prettier was trying to format my elixir files instead of vscode-elixir-ls.

from vscode-elixir-ls.

I'm experiencing the same with Formatter.

from vscode-elixir-ls.

@minibikini it turned out the problem (at least in my own case) was caused by an old elixir-formatter extension which was installed along with elixir-ls.

Removing that extension solved the problem, formatter works again.

Maybe I should close this issue.

from vscode-elixir-ls.

Hm, I don't have elixir-formatter, my formatter is elixir-lsp.elixir-ls.

from vscode-elixir-ls.

@andreapavoni can you send a link to that incompatible formatter that you were using? I'd like to add it to the list of incompatible extensions.

@minibikini Can you send details of your setup? You can get initial details by running the "ElixirLS Fork: Copy Debug Info" command. Also please list your installed extensions and check your logs (via View->Output->ElixirLS Fork) for any potentially relevant info.

from vscode-elixir-ls.

@axelson not sure what happened but it works fine now.

Formatter still hangs for me. Nothing in the ElixirLS logs. :/

from vscode-elixir-ls.

@minibikini have you tried to uninstall your elixir-formatter extension at all? Your files should be formatted anyway.

from vscode-elixir-ls.

@andreapavoni I think my formatter is part of ElixirLS and I can't uninstall it separately. I could disable formatting but prefer to keep it and restart vscode once in an hour (it helps in my case).

from vscode-elixir-ls.

@minibikini Please uninstall sammkj.vscode-elixir-formatter-0.2.0 and try again. Installing that extension reproduced your issue for me and the next version of vscode-elixir-ls will give a warning if it is installed.

from vscode-elixir-ls.

Oh, right. I thought I already uninstalled that.

from vscode-elixir-ls.

thanks, @axelson!

from vscode-elixir-ls.

You're welcome! I'm glad that fixed it!

from vscode-elixir-ls.

@axelson Looks like the formatter still hangs for me 😢
Nothing suspicions in logs.

from vscode-elixir-ls.

After looking again at the logs I found something which looks like ElixirLS error:

@minibikini what OS are you running and how did you install Elixir and Erlang? Maybe you have an incomplete installation of Erlang.

from vscode-elixir-ls.

• OSX 10.14.6
• Erlang/OTP 22 [erts-10.7.1] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe] [dtrace]
• Elixir 1.10.2 (compiled with Erlang/OTP 22)

I'll try to reinstall it, thanks.

from vscode-elixir-ls.

@minibikini but how did you install elixir/erlang? homebrew? asdf? etc.

from vscode-elixir-ls.

Homebrew

from vscode-elixir-ls.

@minibikini Did reinstalling help? I'm not able to reproduce when using elixir installed via homebrew. Does it also fail if you install elixir and erlang via asdf?

from vscode-elixir-ls.

Hopefully, yes - so far it works fine.

I didn't try asdf. Will do if the the issue occur again.

from vscode-elixir-ls.

@axelson formatter still hangs, but it's probably not ElixirLS fault because I've noticed that erlang formatter hangs too. I've tried to install elixir and erlang via asdf, also reinstalled VSCode.

from vscode-elixir-ls.

Hello! This is happening to me fairly reliably. I do not have any other formatters installed or set to my default formatter. My debug info is

* Elixir & Erlang versions (elixir --version): Erlang/OTP 24 [erts-12.1.5] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1]

Elixir 1.13.0 (compiled with Erlang/OTP 24)

* VSCode ElixirLS version: 0.9.0
* Operating System Version: darwin 20.6.0

Elixir and erlang are installed via asdf.

Closing and reopening vscode seems to "fix" the formatter for one formatting action before it begins to hang again. Same with reshimming asdf. There is no other output in the dev console.

from vscode-elixir-ls.

Out of curiosity, I downgraded to 0.8.1 and this still occurs. I was able to format twice in quick succession, but after making some edits and attempting to format again it hung.
