set the channel topic: Need to add Kotlin support for emacs

I was reading the VSCode support to Kotlin

so I was thinking why not emacs:

if someone here has a working emacs configuration and are willing to share, I’ll appreciate it :slightly_smiling_face:

Hi all, what's the status of kotlin on emacs? All I can find is kotlin-mode but it seems very limited

<https://www.reddit.com/r/emacs/comments/81cfu8/intellijlspserver_exposes_intellij_idea_features/?utm_source=share&amp;utm_medium=toast_only_ios_app&amp;st=JHT3IHL6&amp;sh=ab52eb6c>

Anybody here using emacs with kotlin yet??

Yes, all the time. However kotlin-mode is awful so I absolutely have to use both Emacs and IntelliJ. And I have not yet drilled into LSP support. While poor Kotlin support in Emacs is definitely an itch, it has not yet been severe enough to start scratching. Should I find a collaborator that could easily change.

I should also add that I make extensive use of IntelliJ’s Emacs key bindings.  These are pretty solid and very helpful to my muscle memory.

Kotlin mode but there is now a language server so that is a plus.

i'm scared to even look at how to implement that with emacs

Is this the Kotlin language server people are using?

I have this one setup with lsp-mode but I don't seem to be getting much from it. I connect successfully, and set company to a company-lsp backend.....  :confused:

another option is eglot : <https://github.com/joaotavora/eglot>

Do you know for sure that this works for Kotlin? I did a quick try and got an error to the effect that the Kotlin server could not be found.  I’ll chase it down but it would be good to know that it works for somebody.

sorry <@U7JDATBK5> I haven’t tried it personally. I just had it on my list of emacs/kotlin options

I'm working on a PR to add out of the box kotlin language server support for `lsp-mode`.  One thing I was wondering was, where are the majority of you building and keeping your `kotlin-language-server` binary?

Who knew? Somehow the fact that I needed to build anything escaped my attention. It strikes me that rather than just getting a message that the server has not been found, the message should also ask: “have you built it yet?” or some such message.

I have `kotlin-language-server` working with lsp-mode pretty much out of the box, granted you build `kotlin-language-server` per the instructions on it's github and it's added to your emacs `exec-path`.  There are still a couple more kinks to work out but the PR should be submitted soon.  As far as a message for the build, `kotlin-language-server` and `lsp-mode` are two completely different projects unassociated with eachother.  The only thing `lsp-mode` does is act as an execution layer of the client you connect it to.  It doesn't know anything about whether something has been built or not.

<https://github.com/fwcd/KotlinLanguageServer/blob/master/BUILDING.md>

Since the individual is responsible for building the client themselves, I'd like to find a sensible default to have `lsp-mode` look for the binary to start it.  Ideally, this would be a location that is already on your emacs `exec-path`

Anyone using Kotlin with Emacs in 2022 :confused: ?

I use Emacs and LSP to browse code but mainly write code in Intellij. Also use `ob-kotlin` to learn the language.

Wrote some elisp to make it easy to go from Emacs to Intellij:
```(defun jh/intellij-link ()
  "Copy the current file name and line number to Intellij link."
  (interactive)
  (let ((relative-file-name (file-relative-name buffer-file-name (projectile-project-root)))
        (line-number (count-lines 1 (point))))
    (kill-new (concat relative-file-name ":" (format "%s" line-number)))))```

I use two 27" monitors, one for full screen emacs and one for full screen IntelliJ/Android Studio, both showing code buffers in incredibly powerful arrangements. I find that both environments stay in sync, IntelliJ seamlessly, Emacs needs the occasional explicit save operation. I have given up on LSP. Not ready for prime time with Kotlin. YMMV

<@U7JDATBK5> yeah I use something that looks more or less the same. I still use LSP and think it works okey

I made a `ob-kotlin` for myself. It works pretty good and I have been using it while trying to understand Kotlin. <https://github.com/jherrlin/ob-kotlin>
