LSP client for VSCode
I've installed [vscode-nim-lsp](https://github.com/bung87/vscode-nim-lsp) and
[nimslp](https://github.com/PMunch/nimlsp) but it doesn't seems to work.
(auto-completion, linting, hover, F2, F12, etc... doesn't work)
I tried to make one but I couldn't make it work because of my limited knowledge
of LSP and programing in general.
Does anyone have plan to make lsp client for vscode?
Also, I'm very curious about how symbol `renaming`, `reference searching` and
`auto-completion` will work with macro.
For example:
import strformat
var hi = "hi"
#___^ does renaming this variable will also change
echo &"{hi}"
#___^ this too?

Re: Unicode support for Windows 10 console
Thanks for the detailed explanation! `stdin.readLine() # <- Error: unhandled exception: EOF reached [EOFError]` However this error still occurs when using the `fgetws` version. (win api version works as expected.)
Re: Unicode support for Windows 10 console
import console let input = consoleReadLine() # <- Works great! consoleEcho input # <- Works great! Run I think this needs to be in the standard module because using `console.nim` breaks std functions: (at least for me.) stdout.write "something" # <- Error: unhandled exception: index -1 not in ... echo "something" # <- Error: unhandled exception: index -1 not in ... let stdinput = stdin.readLine() # <- Error: unhandled exception: EOF reached [EOFError] Run

^ when using "nim c"
^ when using "nim c --gc:arc"
hmm it outputs (bytes: 1026, data: input) instead of string itself when
using --gc:arc
Re: Unicode support for Windows 10 console
Is checking fgetws result unnecessary?
proc consoleReadLine*(line: var string): bool =
let buffer = newWideCString("", 256)
result = fgetws(buffer, 256, stdin)
if result:
let length = buffer.len
if length > 0 and buffer[length - 1].int16 == 10: #discard '\n'
buffer[length - 1] = Utf16Char(0)
# discard extra '\n' in waiting:
let buffer2 = newWideCString("", 2)
discard fgetws(buffer2, 2, stdin)
line = $buffer
else:
line = ""

Re: Unicode support for Windows 10 console
That's very cool! however let a = consoleReadLine() echo a let b = consoleReadLine() echo b Run if I run this code and press enter echo b also gets executed.

Calling proc with [() -> void] as a last parameter
import std/sugar # if [() -> void] is a last parameter of a proc you can do this(?) proc lambdaTest(a: int, lambdaProc: () -> void) = lambdaProc() lambdaTest(1): echo "[() -> void] as the last parameter." Run Just curious How does ":" syntax work?

Re: Unicode support for Windows 10 console
@ktamp Using your solution fixes Korean but it will still break if I use other languages. (ie: Japanese) Is there any "global" solution for this problem?

Because running nim sets code-page to 65001. I didn't reopen cmd.
Re: Unicode support for Windows 10 console
@ktamp I have a same issue. (can't read unicode input from windows console) I used your console.nim but it doesn't work. i've encountered a very similar issue with zig. [https://github.com/ziglang/zig/issues/5148](https://github.com/ziglang/zig/issues/5148) maybe it's relevant?
Help: Zip (Creating / Opening)
I want to do Something like this.
How can I do this in Nim?
// PATH_FILE_Zip = Path of a Zip file
// Read Zip File's Content Without Unzipping
using (ZipArchive zip = ZipFile.Open(PATH_FILE_Zip, ZipArchiveMode.Read))
{
// Order by File Name
List entries = zip.Entries.OrderBy(c =>
c.Name.Length).ThenBy(c => c.Name).ToList();
for (int i = 0; i < entries.Count; i++)
{
using (StreamReader reader = new
StreamReader(entries[order[i]].Open(), Encoding.UTF8))
{
}
}
}
Run
// Create Temp Folder
const string PATH_DIR_Data = Path.Combine(PATH_DIR_Root, "DATA-Temp");
Directory.CreateDirectory(PATH_DIR_Data);
// Delete Old Zip File
File.Delete(PATH_FILE_Zip);
// Create Zip File
Console.WriteLine("Creating Zip File...");
ZipFile.CreateFromDirectory(PATH_DIR_Data, PATH_FILE_Zip);
// Delete Temp Folder
Directory.Delete(PATH_DIR_Data, true);

Learning & Using Nim as a C# user + Fan logo Redesign
I'm not a programmer, but I'm currently using C# and Unity to make games as a hobby. And I recently discovered this fantastic language! I really want to make games with this lovely language but as an intermediate C# user I can't make a Game Engine by myself * * * So my Questions are: 1. Any Learning resource targeted at C# user? (comparison, difference, equivalent, etc...) 2. Any Korean Learning resource? (I'm not very good at English ) 3. Is there any Good Game Engine for Nim? (maybe Godot? [https://github.com/pragmagic/godot-nim](https://github.com/pragmagic/godot-nim) <\- is it actually usable and better than C# or GD Script?) 4. Is there any UI app Framework beside using web app? 5. How do I Debug in VS Code? 6. Is VS Code the best editor for Nim? (I'm using Windows) 7. I'm not going to make a Game Engine, but is it possible to use 3d Graphics Library? (maybe directX or Vulkan? _just curious :)_ ) # Fan logo Redesign * * * I actually don't think Nim needs to change a logo. I did a logo redesign just for fun! (Inspired by Gitlab Logo)
