Is such HTML template possible?

Ha ha, this is funny, I see what it does :D type Some = ref object v: int template somefn(a: Some): int = a.v = 2 a.v let some = Some(v: 1) echo somefn(some) # => 2 echo somefn(Some(v: 1)) # => 1 Run Good luck debug

Is such HTML template possible?

As it's `Some(v: 1)` to be pasted, it becomes Some(v: 1).v = 2 echo Some(v: 1) Run

Is such HTML template possible?

Templates are code substitution they place the generic parameters where you call them import std/macros expandMacros: somefn(Some(v: 1)) Run

Is such HTML template possible?

Hmm, I don't understand, is there docs that would explain what's going on and why it works that way? Here's another strange example type Some = ref object v: int template somefn(a: Some): void = a.v = 2 echo a.v somefn(Some(v: 1)) # => 1

Nope templates paste parameters where they match in all places.

Anyone tried GPT-4 for Nim?

I’ve been pretty impressed so far with it for nim. It’s worth a try at the least.

The problem, is this a bug? [play](https://play.nim-lang.org/#ix=4sGv) type Some = ref object v: int proc somefn(a: Some): void = let b = a b.v = 2 echo a.v, " ", b.v template sometl(a: Some): void = let b = a b.v = 2 echo a.

Actually it doesn't work, why code below fails to add the "c"? type HtmlElement = ref object tag: string txt: string children: seq[HtmlElement] template `+`(node: HtmlElement): void = it.children.add node template `+`(node: HtmlEleme

Nim in production #2: 100k+ WebSocket connections on one small VM, lots of CPU and RAM to spare

This is a reasonable but also complex question. 1. You can choose how many worker threads you want. I've confirmed having 1k worker threads is totally fine, just totally unnecessary in my case. They all are parked anyway so the overhead is basically zero until and unless you start using them.

Nim in production #2: 100k+ WebSocket connections on one small VM, lots of CPU and RAM to spare

Nice! > In total there are 7 threads and this need does not scale with number of > connections. the documentation notes that "handlers" are free to take over the thread and do lengthy processing, as on of the main advantages over `async` \- "block postgresql" is cited as an example - what happ

Nim in production #2: 100k+ WebSocket connections on one small VM, lots of CPU and RAM to spare

There is not 100k+ threads. There is 1 Mummy socket thread and 2 worker threads for the HTTP Upgrade requests. Then there is 1 thread receiving on a Redis pubsub connection and 1 thread handling heartbeat intervals. In total there are 5 threads and this need does not scale with number of conne

Nim in production #2: 100k+ WebSocket connections on one small VM, lots of CPU and RAM to spare

It sounds very interesting. Can I ask technical question - did you compare with async solution? Because even if it is loong-running websockets - it is still 100k+ threads with context switch and, probably, most of the time websocket is just waiting. I like Mummy's idea to have simple interface

How could I set up an i386 CI for Nim?

Probably it can switch to windows i386, which isn't dropped.

Nim 1.6 vs 2 (1.9) Working with channels

Thanks for your analysis. Yes, I saw in documentation, that channels are unstable with the spawn. Meanwhile, there were no issues so far, except mentioned in the initial post. I've removed lines, which were intended to close the channels let commChanDownData = commStopDown.tryRecv(

Nim 1.6 vs 2 (1.9) Working with channels

It's almost possible with templates :) type HtmlElement = ref object tag: string txt: string children: seq[HtmlElement] template h(html: string): HtmlElement = let node = HtmlElement(tag: html) when compiles(parent_h.children.add node):

Is such HTML template possible?

Btw the karax DSL is not that complicated. The mastering nim book has a bare-bones re-implementation that takes 85 lines total. I would start from there.

because all accurances of `tag` get replaced, so the expanded template would be: "some": "some" Run just give the parameter a different name

A minor question, why this template fails? template h(tag: string): tuple[tag: string] = (tag: tag) discard h"some" Run Error: identifier expected, but found 'r"some"' Run

Is such HTML template possible?

The first test to do when you're faced with "is it possible to do X with a macro" is to check if the syntax parses. By using `dumpTree` from the `macros` module this is fairly easy and it shows that your proposed syntax would indeed be valid Nim: import macros dumpTree:

Nim in production #2: 100k+ WebSocket connections on one small VM, lots of CPU and RAM to spare

I would be interesting to know what the server you're replacing was written in and how the performance of the old server compares to the Nim rewrite. Also a bit of the rationale as to why you've decided to migrate it.
