Edge is stuff tacked on Chromium. How can it be better?!

Thanks.

The link suggests it might be undone after GRUB updates. Maybe I will just edit the line and at the init level at the boot menu.

Ah, yes. I felt a bit uncomfortable posting here, glad to know linux4noobs exits here; subscribed.

 

One can boot into the command from grub by editing kernel parameters.

Another way is edition the grub configuration and setting GRUB_CMDLINE_LINUX_DEFAULT="text". But now it's not possible to boot into a graphical env.

So is there way to create menu entry just for command line so it will be one of the ways to log into the system?

This, .clangd, file in the root of the project directory worked:

CompileFlags:
  Add: [-std=c++20]

Thank you!

I use Helix Editor and by default it uses clangd as LSP server.

But when I use "newer" C++20 features I get warning messages in the editor that they are only available in "later" C++ versions or I get straight up error messages.

So how do I tell clangd that I am writing C++20 code? I am guessing passing an argument (-std=c++20) or creating a "project properties" file...

This is the Helix Editor configuration file, languages.toml:

[[language]]
name = "cpp"
language-server = { command = "clangd", args = [] }
auto-format = true

Please let me know the right way to do it.

True, I myself prefer VS Codium but how many people use it? And some site like Coursera have VSCode on the web and it can't be changed to VSCodium.

I just hope it’s not yet another electron or DOM based editor

Unfortunately, yes.

JS simply does not care.

Cool. What are the objectives?

I am immediately reminded of veloren.

[–] jim_stark 2 points 1 year ago (4 children)

I am not saying otherwise. But do we still have a say?

Aren't we past that point?

VS Code is Electron based and it can even be deployed in the cloud. We are talking about one of the most popular IDEs.

Interesting take!

The documentation uses is in the example for "declaration patterns" but the book I am reading uses a switch statement. But when I try to run the code I run into errors.

using System;

public class Program
{
  public static void Main()
  {
    var o = 42;

    switch (o) {
      case string s:
        Console.WriteLine($"A piece of string is {s.Length} long");
        break;

      case int i:
        Console.WriteLine($"That's numberwang! {i}");
        break;
    }
  }
}

Error:

Compilation error (line 7, col 6): An expression of type 'int' cannot be handled by a pattern of type 'string'.

EDIT

Changing from

var o = 42;

to

object o = 42;

worked.

What does "control falls through a switch statement" mean in this context? Control just moves on to the next statement?

I thought if there is no match and a default case doesn't exist it will raise an exception. Is it not true?
