Kakoune with Ubuntu WSL (windows platform) to use clangd with kak-lsp

lauccode · April 19, 2019, 9:18am

I guess kakoune under WSL can be a good solution if we would like to use it under Windows.

Kakoune version has been installed with the git clone
$ kak -version
Kakoune v2019.01.20-203-g06d4ee57

WSL Ubuntu version is
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.2 LTS
Release: 18.04
Codename: bionic

Clangd version installed with apt-get is
$ clangd --version
clangd version 7.0.0-3~ubuntu0.18.04.1 (tags/RELEASE_700/final)

kak-lsp can be launch
$ kak-lsp
Apr 19 10:50:19.208 INFO Starting main event loop, module: kak_lsp::session:31
Apr 19 10:50:19.209 INFO Starting editor transport on 127.0.0.1:31337, module: kak_lsp::editor_transport:106

Debug buffer of kakoune

Config-change detected:

and kak-lsp.toml has been modified and moved from .config/kak/plugins/kak-lsp/ to .config/kak-lsp/

But when I launch a “.cpp” with Kakoune, I don’t see kak-lsp activation.
I should see the error code activation on the number line column.
And other clangd functionnality.

Other strange behaviour is that I can not see the kakoune command :ranger ??

Maybe someone can help ?

that’s strange location for kak-lsp

There’s no such command in Kakoune anymore.

Perhaps you could provide your configuration files for us to examine. What lsp-compatibilities says?

lauccode · April 19, 2019, 12:53pm

You are right, correction is has following (I corrected it in the subject too):
from .config/kak/plugins/kak-lsp/ to .config/kak-lsp/

Why ranger.kak has been removed ? This is useful feature to use it.

Configuration file kak-lsp.toml is
[language.c_cpp]
filetypes = [“c”, “cpp”]
roots = [".cquery", “compile_commands.json”]
command = “clangd”

There is no event (no more clippy help) when I do lsp-mode -> lsp-compatibilities

andreyorst · April 19, 2019, 1:23pm

clangd doesn’t use .cquery as root indicator

lauccode · April 19, 2019, 1:27pm

I replaced with

roots = [“compile_commands.json”]

But I have the same behaviour.

andreyorst · April 19, 2019, 1:53pm

Proper config would be:

[language.c_cpp]
filetypes = ["c", "cpp"]
roots = ["compile_flags.txt", "compile_commands.json"]
command = "clangd"

lauccode · April 19, 2019, 2:04pm

I replaced roots line as you advice.
This is not working too with same behavior.
But I don’t yet provide compile_flags.txt under the project.

This was working well with original kak-lsp.toml under Manjaro and now under openSuse (to try because I changed SSD).
That’s why I’m wondering what I could mess trying to use kakoune under WSL.

andreyorst · April 19, 2019, 2:06pm

compile_flags.txt has the same syntax as .cquery except there’s no comments and empty lines

lauccode · April 19, 2019, 2:13pm

I put compile_flags.txt with

%clang
%c -std=gnu11
%cpp -std=gnu++14 -pthread
-I/work/cquery/third_party
-I/work/cquery/another_third_party

(no more improvement)

andreyorst · April 19, 2019, 2:55pm

I don’t know how WSL actually structured, so I can’t really help with anything besides configurations of kak-lsp

lauccode · April 19, 2019, 4:07pm

Don’ t worry and thanks for your help.
Maybe someone else will succeed to use it under WSL.
We will have confirmation that kakoune is also available under Windows.

Hello! It might worth trying to run kak-lsp server manually with debug logging for better understanding of the problem.

Try to do kak-lsp -s mysession -vvv in one terminal, and open file inside your cpp project with kak -s mysession src/path/to/my/file.cpp afterwards in another one. Debug output in the first terminal could have clues for goes wrong.

Hello Andreyorst,
How do you proceed if there is no more ranger command to navigate in your project ?
Regards

andreyorst · April 22, 2019, 9:29am

I never used ranger actually. I use fzf.kak to search and open files in my projects.

alexherbo2 · April 22, 2019, 10:23am

@lauccode ranger has been removed because it was too specific.

lauccode · April 23, 2019, 8:08am

Hello ulis,
I tried but I got no more information.
Opening kak does not do anything.

$ kak-lsp -s mysession -vvv
Apr 23 10:05:04.229 INFO Starting main event loop, module: kak_lsp::session:31

lauccode · April 23, 2019, 8:39am

Maybe it could become a ranger plug-in ?
I need to have a look on andreyorst “fzf-project” which seems to be a good candidate to navigate in project.

alexherbo2 · April 23, 2019, 9:03am

You can use ranger with Connect.

connect ranger

Thanks
Decidedly kakoune is resourceful

lauccode · April 24, 2019, 10:28am

Hello ulis,
Is there a way to check that clangd is responding ?

Kak-lsp seems well set and is running. Kakoune also.

But when I open a cpp file , I can not see the error bar added in the number line columns. It should work even with no files in the root project (compile_flags.txt", “compile_commands.json”).
