Need more detailed guide on how to set up helix as external editor for Godot

[Multirious]

I'm trying to set up Helix as external editor for Godot 4.0. It works a little bit but there's still some problem involving the LSP.

It's seems like not a simple job. The steps I need to get through is not documented and I've solved it with some trial and error.
This is what I did:

1. Helix need a terminal to run with. I've tried to use Window's cmd and powershell but for the life of me can't figure out how to make the command work (like "/C" flag and stuffs). I decided to installed Cmder (I'm gonna install it later anyways) and find some batch script that allows me to run command as input for Cmder executable.
2. LSP config. I configured Helix language with the How to install the default language servers guide with no additional settings and some nc and ncat path problem, nothin' much.

After has been done, at first, it seems to work. Then for awhile, Godot saids that Max client limits reached which is 8 in the source code.
My theory is that the LSP didn't disconnect when I :q in Helix. What's next?

Read helix#installation.

create CONFIG_PATH/helix/languages.toml, add content of setting.

[[language]]
name = "gdscript"
language-server = { command = "nc", args = [
  "127.0.0.1",
  "6005",
], language-id = "gdscript" }

Append nc into PATH of environment variable.

Yeah, well, as long as this powershell script works that I'm good for awhile.

param ($file, $line, $column)
$wshell = New-Object -ComObject wscript.shell;
$wshell.AppActivate('cmder')
$wshell.SendKeys(':o "' + $file + '":' + $line + ':' + $column + '{ENTER}')

Works absolutely fine in terminal.
But damn Godot. What more do I need to doooooo

[erasin]

Most likely the parameters are the cause.

If hx is already open, you can check if the parameters are correct, or if the script has output content, or if there is a return content that may cause godot to display an error.

Godot may provide only one parameter. it is better to print the parameter and see the result.

[Multirious]

If that's the case then that's kinda weird, since the error output is C:\Users\Windows10\scripts\helix_godot.ps1 "C:/Users/Windows10/Projects/Godot/Mechanica Clone/scripting/script_function.gd" 0 0 which seems ok. Let me update my script...

[erasin]

As I understand it, it should be like this.

1. open cmder
2. hx godot_project in cmder
3. open godot project

setting in godot :

exec path:       C:\Users\Windows10\scripts\helix_godot.ps1
exec flags:      {file}:{line}:{col}

content of helix_godot.ps1 :

param ($file)
$wshell = New-Object -ComObject wscript.shell;
$wshell.AppActivate('cmder')
$wshell.SendKeys(':o "' + $file + '{ENTER}')

[Multirious]

Parameter doesn't seems to be the reason... With my new script and yours and it still doesn't works. I'm thinking maybe Godot can't run powershell. I'm gonna try to create a batch file that runs the helix_godot.ps1 and maybe that would work.

Update: This is terribly hard to do for some god damn reason. There's path spacing problem and argument bullcrap with also unreliable send keys I just realised. I'm gonna go write the script in Rust now.

Soon linux is gonna be my main operating system

I'm trying to do something similar in Linux to try out Godot + Helix. So far, this is the closest thing I've found!
