I am on a MacBook. I have added all the required config files, but the LSP doesn’t seem to work. I can see all the options listed in the command area but can’t see the completions as I type. I see completions for only the code that is already available in the file. I have copied the default `kak-lsp.toml` to `~/.config/kak-lsp/kak-lsp.toml` and have also installed kak-lsp using brew. I initially tried installing it via plug.kak but I got an Error 101, so I reverted to installing it via brew.

Any help on this would be highly appreciated.

Did you run `lsp-enable`? Which server are you using, and what is the input file?

[This command](https://github.com/kak-lsp/kak-lsp#default-configuration) should give you a kakoune instance with working LSP support, plus a log file (which could point out any errors).

(Unfortunately, kak-lsp is a bit hard to set up but I’m sure it will be worth it. We should try to show the last few thousand log lines inside the editor.)

Also, check the `*debug*` buffer for suspicious messages

I don’t see the command `lsp-enable` in my command completion. I see `lsp-enable-window` though. If I add that to the kakrc, the `debug` buffer says that it is already loaded. Apart from that, I don’t get any error message in debug buffer. I suspect some silly issue with path in mac?

**`kak-lsp.toml`**

I have a config for other languages too. But, I am getting it to work for JS or TS at least for now. I have copied the default config from the plugin to config directory, but with some modifications.

PS: I will soon try to replace pics with code.

typescript-language-server on a simple JS file works for me:

Make sure kak-lsp and typescript-language-server are in your $PATH

The error shows that kak-lsp tries to run the `flow` server for javascript, which is the server in the default config.  
This means that kak-lsp didn’t pick up your kak-lsp.toml. Refer to [Configuring kak-lsp](https://github.com/kak-lsp/kak-lsp#configuring-kak-lsp) for how to find the location. In particular, on macOS it’s _not_ `~/.config/kak-lsp/kak-lsp.toml` but `~/Library/Preferences/kak-lsp/kak-lsp.toml`

(FWIW recent versions of the `dirs` library have changed to `$HOME/Library/Application Support` but kak-lsp does not use that yet. Probably it should, while still falling back to the old path.)

Are you sure `~/Library/Preferences/kak-lsp` is where we need to house the `kak-lsp.toml`? When I `ls` into this directory, all I can see is a bunch of plist files.

Edit: You were right, it seems to be picking the config file from `Preferences`. However, I don’t see the required auto-completions yet.

Here’s what VS Code shows:

works for me, can you post a full log (where `lsp_cmd` has `-vvvv`)

Here is the log file with `-vvvv` like you asked. Everything seems to be normal from what I can see within the editor. Even the `lsp-capabilities` return some options except that they’re not shown in the completion. Really confused what might be happening here.

Sorry about the large log. I didn’t have an option to attach a file.

when you enter insert mode, the editor should send a completion request with log entries like the three lines below (here my cursor is just after `arr.`). If you don’t get them, can you check the `*debug*` buffer for error messages?

> recursive call of hook InsertChar/', not executing.

kak-lsp does not add InsertChar hooks. This is likely some bad InsertChar hook in your config.

It’s often a great idea to try with a _minimal_ config, to isolate root causes.  
This shell script should work for you. Since it uses a temporary $HOME, it won’t read your `~/.config/kak/kakrc`.

```shell
tmp=$(mktemp -d)

echo > "$tmp"/kak-lsp.toml '
[language.javascript]
filetypes = ["javascript"]
roots = ["*.js"]
command = "typescript-language-server"
args = ["--stdio"]
'

echo > "$tmp"/test.js "
function addTwoNums(n) {
	var nums = ('' + n).split('')
	var arr = ['a'];
	arr.
	return 1
}
"

HOME=$tmp kak -e "
    eval %sh{kak-lsp --kakoune -s \$kak_session}
    set global lsp_cmd \"kak-lsp -s %val{session} -vvvv --log /tmp/kak-lsp.log -c $tmp/kak-lsp.toml\"
    lsp-enable" "$tmp/test.js"

```

Yes!! It was some error in the config stopping rest of the commands from executing properly. Tried commenting a few lines and was finally able to find the section that was causing the issue. One curious question though, it shows the suggestions properly now (`methods, vars.. etc`), but, is there a way to get an explanation for each like the above screenshot of vs code? For a method, I would like to know what args it accepts and what it returns… signature sort of.

and thank you so much for the helping hand. It would’ve been difficult without you guiding me in the right direction. Having a forum like this is really a boon.

That was a bug in kak-lsp (sadly LSP allows servers and clients to do many weird things). Fixed as of [Support resolving completion items' "detail" and "documentation" fields · kak-lsp/kak-lsp@6bee0a1 · GitHub](https://github.com/kak-lsp/kak-lsp/commit/6bee0a132ea7efd1d3b37be7676c2b84bec74382)  
Thanks for reporting!  
I wonder if we should switch the default language server for javascript from “flow” to typescript-language-server, since that’s what VSCode uses. I rarely use javascript so I dunno

Most of the editors I used and projects I worked on uses the `typescript-language-server`. I think it’ll be a good idea to change to that for the benefit of new users. If it’s possible to leave the config for `flow` under a comment, that’d be good too. But, ts-server being default makes sense.
