push/pop hints on/off not working?

I've been trying to silence one million different hints coming from system (std) libraries, but I still cannot manage to see how... Here's an example of what I mean (the list is practically endless, this is just a sample - and the problem is that amidst all these, I cannot spot the warnings and

Version 1.4.0 released

I started a thread some time ago to keep track of ideas to improve the front page: Unfortunately I've not found the time to spend on actually making a PR to [nim-lang/website](https://github.com/nim-lang/website) to update the wording.

We should make it simpler for authors to have their blog featured on the Nim front page.

If Nim blog could accept more articles, it will be benefit for marketing! @leorize Document a baseline standard for articles to be considered for publication. This will let authors know beforehand whether their blog meet the scope of the Nim blog before submission. I agree

Can I use async/await to work with JS Promises?

Thanks! I also found out that `async` by itself basically [makes a function wrap its returned result in a Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function#Description) \- so I can just [pass an async function into .then()](https://github.com/a

Ubuntu, snap install, "Error: cannot open file: strutils"

I am having trouble using the standard library. I installed nim through the snap "store" (1.4). First of there's a prefix on all of the nim cmds like "nim-lang.nim, nim-lang.nimble" etc. I solved that by symlinks but it does not matter if I use the symlink or directly acces the binary, a simple

Impressive results with --gc:orc

I don't think it makes too much of a difference if you're using `--exceptions:goto`, but might provides considerable boost if `--exceptions:setjmp` is used. `--panics:on` allows the compiler to stop assuming that all procs can throw, as all `Defect` will then be compiled down into `quit()`. Thi

Impressive results with --gc:orc

How about `--panics:on`? Does it make a significant difference?

Impressive results with --gc:orc

\--panics:on is mostly for code size, not performance, there wouldn't be much difference if you already do -d:danger|

Impressive results with --gc:orc

For that matter you can also try `--passC:"-flto"` if your C compiler supports LTO - it should give some more perf boost

No, I didn’t. I’m using -d:release. I’ll have to give it a try.

I ran into this and other issues on CentOS 6: where at least SCL's devtools is an easy escape hatch to a newer compiler.

1.4.0 failed with old-ish gcc because of NIM_STATIC_ASSERT bug

Please report bugs on Nim's [issue tracker](https://github.com/nim-lang/Nim/issues) so we can track and let you know if the bug is fixed. AFAICT support for older gcc is also a priority in Nim as we aim for embedded support (where there are odd versions of gcc everywhere).

1.4.0 failed with old-ish gcc because of NIM_STATIC_ASSERT bug

In new 1.4.0 release, **nimbase.h** defies the macro `NIM_STATIC_ASSERT`, trying some possible implementations depending on C compiler version used. The last fallback option uses a `NIM_STATIC_ASSERT_AUX` trick ( **nimbase.h** line **275** ), which does not work. This macro is used twice in the

Thanks for the remarks, will try to fix that soon.

sets : what are they

Sorry Stefan, i didn't saw your post before today. I was talking about sets in nim to a friend, so i read again this thread and saw you post. I have read the new section in your book, and it's clear for me. It was welcome to strengthen my comprehension of set, that i haven't used since this ques

Is Nim good for creating video games?

Nim is ideal for games. It hits the right tradeoff between speed / safety / ergonomics. The last one is particularly important to me...a language can be as fast / safe as can be, but if i'm spending large chunks of my day waiting for my code to compile or fighting compile errors, there is a wide

Is Nim good for creating video games?

The next question is : what options are available ? If you want 2D you have a lot of option: Nico, NimGame2 (seems stalled) and Norx (1:1 port from Orx C lib). For learning, i would use Nico, which has been written entirely with Nim, and which is used by its author:

Aliases with templates for tables not working in v1.4

Thanks, I'll try that.

Impressive results with --gc:orc

@didlybom: I am curious whether you are passing `-d:danger` instead of `-d:release` to the Nim compiler? It may further boost performance by disabling runtime checks.

I just recompiled a small tool that reads a binary file and converts it into a different (text-based) format using nim 1.4 and the new ORC GC. This tool did not compile with the ARC GC in 1.2.6 (due to some problem with the docopt library) but it complies just fine (both with ARC and ORC) in nim
