Nim's version of the Trojan Source vulnerability

My Neovim displayed that code like `if access_level != "user<202e> # check if admin⁩ ⁦":`. But my Neovim doesn't show any garbage charactor in this code: proc runBadCode() = when defined(windows): echo "format c:" else: echo "sudo dd of=/dev/sda1 if=/dev/

Thank you @Vindaar. It works perfectly. I’ve opened a new issue because when compiling with nim 1.6.0 there is a deprecation warning. It’s true that it’s fairly easy to provide the x sequence but it’d be nice if it weren’t necessary. It’s not super important but a lot of plotting libraries (e.g

How can I query if an element is in a Tensor without converting to a seq first? `in` / contains seems missing

Arraymancer: dot/matmul equivalent for higher-dim tensors

I'd like to do this with dot, but also einsum only supports tensors of known dimension. For instance, my code cannot be passed a tensor of dim 4 or 5 (typically some DL routines like to abstract away the concept of batch an be able to process tensors with one extra dim for batch).

while not a priority, I think this could be a nice easy/hacktoberfest-esque task for someone to implement detection of this in the Nim compiler :)

Nim interpreter

Well the Nim compiler includes a virtual machine (compiler/vm.nim) that can interpret Nim code. A "superset" would probably imply to patch Nim's parser/vmgen/vm so that it interprets this "superset", whatever that implies. But if you think that compilation/interpretation has much to do with how

Do you see a red triangle or rectangle if your fragment shader outputs red color like `FragColor = vec4(1.0, 0.0, 0.0, 1.0);`? If you still see a black screen, your problem is not a texture loading.

Most people would use an enum for this. If not, you would individually cover the case of the string being "admin" and all other possible values instead of assuming an invalid value to be admin. I would also expect editors like VS code to already highlight invisible characters. Either way though,

Hello, I'm about to include some Nim code into my CMake with C++. I managed to get most of it going; one thing I couldn't find though is a way to resolve Nim include path. The nim compiler generates an interface header file for me to use; however, it, in turn, depends on including a Nim library
