Not working on linux ( at least not flatpaks )

[sfjohansson]

Flathub is very popular for installing apps on linux: https://flathub.org/apps/dev.zed.Zed

[Maligan]

Thank you for report, will try reproduce on virtual machine :-)

[sfjohansson]

I'd be happy to help, I'd assume it might just be just the discovering of zed here:

    public class ZedDiscovery
    {
        public CodeEditor.Installation[] GetInstallations()
        {
            var results = new List<CodeEditor.Installation>();

            var candidates = new NPath[] {
                new ("/Applications/Zed.app/Contents/MacOS/cli"),
                new ("/usr/local/bin/zed"),
            };

Perhaps an option to manually set the path is an easy option that solves most cases

[Maligan]

Does flatpak have a default installation places? In cases for per-user installation and per-machine installation?

As I see there are a system-wide /var/lib/flatpak/ and user-wide ~/.var/app/ but I have to check them to be sure...

[sfjohansson]

you can actually use the terminal command to get app information

flatpak info dev.zed.Zed

Yes, I did try this way but it has several cons:

• Unity call this method to discovery too often in UI thread, so asking for shell execute cause hard freezing
• There is no guarantee that flatpak is exposed to Unity $PATH (for Mac there is such a problem) so I have to discovery flatpak itself before using it :-(

Anyway I didn't add default installation paths for Linux/Windows and will try them at the first step, If this doesn't help I will add custom GUI into Preference tab.

[sfjohansson]

just checking it on startup and save it somewhere could be an option:

using UnityEditor;
using UnityEngine;

[InitializeOnLoad]
public static class EditorStartup
{
    public static string pathExternalEditor;

    // Static constructor
    static EditorStartup()
    {
        // This code will run when the editor loads
        pathExternalEditor = "Editor Loaded at: " + System.DateTime.Now;
        Debug.Log("Editor has started. Static string saved: " + myStaticString);
    }
}

I just tested the 0.2.1 Release and my flatpak installation is discovered. I can select it and it will open scripts in Zed.

Should the csharp solution work fully, ie going to implementations of this or that, finding usages etc?

I returned a little later and it kicked off indexing the project. It racked up some 140k warnings in the solution. I managed to navigate to class via a field usage before it crashed.

I assume the last is based on Zed just having had enough and tossed in the towel...

[Maligan]

Oh, thank you I implement only discovering of system installation of Zed will do it for userwide!

Zed use C# language server via omnisharp https://zed.dev/docs/languages/csharp

It works perfect for small-to-medium pet project of mine, but crashes when I try to start my huge working project ~ 160 asmdef etc. 3GB of RAM usages.

I check the status of omnisharp via task manager and it really has some problems.

Unfortunately it's a Zed's problem. Maybe I can tweak some behaviors with changing workdir settings but I can't find omnisharp integration docs / configuration which can help with that.

[sfjohansson]

Probably not many that uses Zed for C# at this point...well I'd say that the issue of discovering Zed is resolved! :)
