VS Code Nim Extension in Nim

I took a quick scan and this looks like exactly what I need, thanks so much! Also gives me another place to go spelunking because there is a bunch of overlap in this area. I also did a quick search in the git repo and I see hits in `nimsuggest` and `nimfind`, which got me thinking does a `findA

this sounds like a tough problem to debug, I doubt i'll be able to help, unless this: cImport(includeDir/"mupdf/fitz.h", dynlib="dynlibFile", flags="-f:ast2", recurse=true) Run is a typo: should that be `dynlib=dynlibFile` without the quotes?

[noob] Help with sets

I don't think the point has been made clearly enough: the default `set` is a bitset. For _every possible value of the type_ , it stores a bit indicating whether it's present in the set. So you should use it only if the type has a limited range of possible values — usually with `enum` or `range`

I am trying to load an image in `nimx`, but it always adds the current directory plus `/res`. It is related to [this issue](https://github.com/yglukhov/nimx/issues/435) I posted in github. Does anybody know how to avoid that behaviour? I just want to use [this](https://github.com/yglukhov/nimx

Hi all folks! I'm writing this because I'm looking for collaborators for one of my side projects, it's a bytecode virtual machine for a (currently) toy language that I've been developing lately following an amazing book available for free at craftinginterpreters.com, you may find more technical

This is true for something like `(foo +1)`. But `(1 +1)` cannot be interpreted as a function call. In any case, I am not criticizing Nim's design decisions and I like the fact that it is different from other languages in a good way. But when it is "unexpectedly different" one needs to properly d

Well yes, but `+` is a unary operator. In fact, the spacing determines if an operator is unary or not. And that's what the manual says, you quoted the section.

[Similar parsing features](https://forum.nim-lang.org/t/6189). Using correct spacing is important in Nim, for the parser and for those who read your code.

Update on --gc:arc

No, immutable data structures continue to be problematic for non-atomic reference counts. But you can use atomic reference counting for that and hack around the fact that it is "logically immutable -- except for the reference count operations".

That was why we removed the unary `<` operator when people started to have bugs in their `1 .. <10` expression. Also note that whitespace will change precedence of `1 + 2 * 2` vs `1+2 * 2`

Calling same-named-function from abstruct object

I think Nim already has all the mechanisms needed to prevent this type of code injection. If I have a module `foo.nim` with templates containing late binding `mixin` code I, as a provider, can only expose my clients to a carefully restricted `foo_api.nim` that only exports safe and hygienic code

Update on --gc:arc

Will immutable imply isolated? The [RFC244](https://github.com/nim-lang/RFCs/issues/244) doesn't say so, but [write-tracking](https://nim-lang.org/blog/2020/09/01/write-tracking.html) is coming, and would make sharing immutable structures possible.

I found the following behavior puzzling: echo(1+1)# prints 2 as expectted echo(1 +1) # Error: in expression '1 1': identifier expected, but found '1' Run Notice a space between `1` and `+` in the second line. That makes all of the difference. Apparently, on

I usually use something like this: * !/**/ !*.* *.exe # anything else you want to ignore Run The top section will ignore everything, then add back directories and anything with an extension. Kind of a hack, but it works.

it there general gitignore configs for binaries?

Not sure about `.gitignore`, but you might also avoid your problem with `nim r tests/xxx.nim` which is fewer keystrokes and also should put the binary executables in the build cache directory (whatever `nimcache` is set to in the relevant `nim.cfg` | `config.nims` file).

`nimble c -r tests/xxx.nim` always generate binary files. I used it to run tests very frequently thus generated several binaries in different names. Can be annoying sometimes. Do you have any general configs of `.gitignore` for handling this?

I know that int alone is int64 cause int is defined to be as the size of a pointer and int64 is not allowed as written in the tutorial. So it seems i need to write the first number's type in the set explicitly to define the sets type.

When you use callbacks like type S2[T;F:static[proc(a:T, b:T):T]] = object # can be defined discard Run The slowness is if those callback are actually closure that would be dynamically allocated. Instead you can ensure that the call is from a proc that is static

Yes! I know it. I will explain the detail. I want to make an object that have data and do some operation among these data. These data and operation should be settable by user. For example, the following code will do such thing, i.e. proc f in S can be set any function like `+`, `*`, min, max.

The scope of your `<` must be the global scope. (And we should really have that in the spec...)

I do not really understand your question, and I still wonder what a "abstruct" from your other thread is. But do you know that you can use typedesc as proc parameters? So you can declare class methods or static methods as known from other languages like Python, see
