Starting polymode with lsp, makes the cursor to jump to the end of buffer

[maikol-solis]

I have this problem when I try to edit Rmd files.

In the video happens several things:

1. A fresh opened file (test.Rmd) works as expected. I typed the letters abc several times without problem.
2. Around the second 0:23 I started polymode and execute the fenced code. Here LSP is also activated.
3. After that (second 0:50), every time I type a character the cursor jumps to the end of the buffer and operations like delete-char, backward-char, etc., become unreliable.

pm.mov

My undesirable workaround for the moment is disabling polymode completely, edit my Rmd in Emacs and run everything in Rstudio.

[gdkrmr]

I can confirm this, it basically makes it impossible to edit the file

[jrgant]

I'm also experiencing similar behavior. I basically can't work with Rmd files while in polymode.

[gdkrmr]

I think the culprit is lsp-managed-mode if you navigate inside of a code chunk and disable lsp-managed-mode there, the jumping stops. I havent' tested this extensively yet.

@yyoncho

Please help.

[AlexDaniel]

It used to work OK, but now after upgrading something it indeed became unusable. :(

[AlexDaniel]

Alright, I found this commit: 2094c92#diff-7a892d2433cc77b44621c3724f45b25815a7c3c98ad7fa9b6531ca252f927ff3R308

So I went to the source code of the package and changed t to nil. Now the cursor no longer jumps. I have no idea what it means for lsp, I use it but not as much. Probably it breaks lsp, but at least polymode itself works.

[AlexDaniel]

Now more than one month later, I updated emacs and all related packages, and my hotfix to the file was reverted. This immediately brought the problem back. I edited the file again and the workaround is still working.

[jrgant]

@AlexDaniel Thank you for this sleuthing. Seems to be working for me too.

I decided to set polymode-lsp-integration in my config.el for each language mode I use regularly in polymode, which should avoid having to reset this variable in the polymode source every time the package gets updated.

I use Doom Emacs, so you might have to set the hooks differently if you don't, but here's what I'm doing now:

(setq-hook! ess-r-mode polymode-lsp-integration nil)
(setq-hook! sh-mode polymode-lsp-integration nil)
(setq-hook! yaml-mode polymode-lsp-integration nil)
(setq-hook! markdown-mode polymode-lsp-integration nil)
(setq-hook! python-mode polymode-lsp-integration nil)

[maikol-solis]

I have a (setq-default polymode-lsp-integration nil) as a drastic alternative.

[kchanqvq]

(setq-default polymode-lsp-integration nil) doesn't remove the jumping for me QAQ
