Thanks for your response! I’m pretty sure that solves the `How do I locate the installed files from the binary run in the bin folder? Is there a good way to write a proc to find this on run?` issue by doing something like this: proc findStaticPath(): string = result = current

Nim “free(): invalid pointer” segfault (dynlib)

Would you explain why? They are already defined like this: EventHandleProc = proc () {.gcsafe, nimcall.} CardSetLoadProc = proc (): Table[string, CardObject] {.gcsafe, nimcall.} Run And did you mean `EventHandleProc`? `CardSetLoadProc` works without any issues.

It should be fine, because CardObject is not a ref, and afaik shouldn’t be using lib memory, although idrk.

Why are let variables not gcsafe? + General Threads and GCSafe understanding help

Thanks for your reply! I had something similar set before with a wrapper proc, but decided to change it because changing all the arguments twice was tedious. I am going to retry that method but with a template or macro to make it easier.

Errors within async are not being raised

It seems some exceptions are being raised within an awaited async function, but the program stops without a raised error. It also might have to do with cligen dispatching an async proc, although I have no idea how I would efficiently change this. Reproducible Example: import std/[

I adapted it to use nim DOM, link [here](https://gist.github.com/thatrandomperson5/fcc59ac4814a601d2d00ac18f5e3eb6d). The issue is that this is made for correct nim, but to work with a live text editor, it needs to handle broken nim code too. Right now I fixed it using a `try except`, but there
