Emacs: Package cl is deprecated #1516

Closed peerst closed 1 week ago

peerst commented 4 months ago

Describe the bug

Using erlang-ls the first time shows the warning: Package cl is deprecated

I assume this will cause issues further down the road.

To Reproduce

On MacOS 14.1 MacBook Pro with M3 chip with a pretty recent official Emacs for MacOS: Version 29.2 (9.0)

Copy the .emacs content into a otherwise empty one from here: https://github.com/erlang-ls/erlang_ls/blob/main/misc/dotemacs

Start emacs: it downloads and compiles everything with a ton of warnings.

Then open first *.erl file in a project.

Expected behavior

No warning message.

Actual behavior

Error message: Package cl is deprecated

Context

This seems to be cause by lsp-mode or some lsp-mode specific setup: after switching to eglot it no longer occurs.

So if eglot is the future this can't affect. Could probably be closed, depending on what the plans for lsp-mode support are
