Super-weird error with builds on latest Windows runner (Github)

Adding `-Wno-error=incompatible-pointer-types` to (via --passC or similar) as suggested by lou15b in that thread should be enough to get around this issue.

Can I check if a proc is async at compileTime without a macro?

As an aside, `a is proc(): Future[void] {.nimcall.}` is true.

Can I check if a proc is async at compileTime without a macro?

`a() is Future`?

Can I check if a proc is async at compileTime without a macro?

Parentheses need to go around a(), not `a() is Future`. Typeof doesn't evaluate its argument at compile time, so slapping some default(T)'s in there should work.

Errors within async are not being raised

The program quits after "u 25" because the code generated by cligen.dispatch discards the Future returned by main. Try making main non-async by replacing `await client.getFile` with `waitFor client.getFile` and removing the `async` pragma, or making a new proc calls `waitFor` on main and dispat

Does seq have a method to get mutable ref element?

`var list = @[1,2,3] for n in list.mitems: if n == 2: n = 3 echo list == @[1,3,3] ` Run

Why json hooks doesn't work for CountTable[int]

Looks like it's because std/jsonutils.toJsonHook for tables only accepts those with strings for keys. Converting the keys to strings when building the table should work: proc toJsonHook*[K](t: CountTable[K]): JsonNode = var t2: Table[string, int] for k, v in t: t

Error: expression has no type (or is ambiguous)

If that's [stripLineEnd from std/strutils](https://nim-lang.org/docs/strutils.html#stripLineEnd%2Cstring), it operates in-place and doesn't return anything. Consider using it with [dup from std/sugar](https://nim-lang.org/docs/sugar.html#dup.m%2CT%2Cvarargs%5Buntyped%5D).

Can I add Procs to Enums in Nim like in Python or Rust?

Enums are just like any other type. You can "attach" procs to them like you can any other type. Here's the equivalent of that Python enum code: import std/strformat type Mood = enum Funky = 1 Happy = 3 func describe(mood: Mood): (string, int)

jsFetch fetch

Looks to me like an unintentional omission in `std/jsfetch`: func newfetchOptions*(metod: HttpMethod; body: cstring; mode: FetchModes; credentials: FetchCredentials; cache: FetchCaches; referrerPolicy: FetchReferrerPolicies; keepalive: bool; redirect = frFollow; refer

`$` not working on custom type when imported in other modules

If we call `$` explicitly, we get a more illuminating error message: `Error: ambiguous call; both dollars.$(x: int64) [proc declared in /path/to/lib/system/dollars.nim(14, 6)] and lib.$(i: Int_b) [func declared in /path/to/lib.nim(3, 6)] match for: (Int_b)`

How to read GeoLite2 mmdb files?

There's my [nim-mmdb](https://github.com/z-/nim-mmdb) which is a pure Nim implementation and is reasonably feature-complete as far as I know; see [here](https://github.com/z-/nim-mmdb/blob/9a4138d94dc044a82a97902c412f0f590e92054d/src/mmdb.nim#L437) for example usage. (C

In Nimpy how to call methods on Python objects? (Example sys.path.insert)

It works when you add `discard`: import nimpy let sys = pyImport("sys") discard sys.path.insert(0, ".") Run The problem with the original code is that Nim does not allow return values to be implicitly discarded.
