| 01:09:56 | FromDiscord_ | <exelotl> is there a way to tell nimsuggest to ignore a symbol? (particularly this could be useful to hide exported procedures that are only used in macro-generated code) |
| 01:12:40 | FromGitter | <zacharycarter> not sure - would probably have to dig into the nimsuggest src to find out |
| 01:12:46 | FromGitter | <zacharycarter> https://github.com/ValveSoftware/GameNetworkingSockets - looks like valve just renamed this repo |
| 01:12:53 | FromGitter | <zacharycarter> would be nice to get bindings around this |

| 14:28:51 | masterm | hey. another n00b question: I have a C function like this: some_func(char* buf, int bufsize); <- this returns a string in buf (truncated to bufsize). what is the idiomatic way to wrap this in Nim? |
| 14:30:07 | FromGitter | <zacharycarter> lolol @ same person comment |
| 14:30:29 | FromGitter | <zacharycarter> man - I was just thinking back to a conversation I had with a co-worker back in April - ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5bba1884e65a63433698febd] |
| 14:31:15 | TheLemonMan | masterm, allocate a string of length bufsize and pass its address to buf |
| 14:31:53 | leorize | convert it to cstring then pass it to be precise |
| 14:32:08 | leorize | Araq made me do that for one of my PR |
| 14:33:38 | masterm | TheLemonMan: should I just choose some arbitrary bufsize value that should be "large enough" and then return the resulting string? so that the wrapper function is: proc some_func_nim(): string? |
| 14:34:02 | masterm | leorize: arent's strings implicitly cast to cstrings? |
| 14:34:23 | leorize | yea, that's the idea, not passing `addr string` |
| 14:35:08 | TheLemonMan | masterm, it depends, if your heuristic catches 99% of the cases go for it |
| 14:35:26 | TheLemonMan | otherwise let the user override it and provide the bufSize themselves |
| 14:36:09 | leorize | masterm: https://github.com/nim-lang/Nim/blob/269b957e2968345a4c9a5037ab97ab726135a921/lib/pure/os.nim#L1484 here's an example in stdlib for a proc like that |
| 14:36:20 | FromDiscord_ | <smitop> How do I do malloc in Nim? |
| 14:36:52 | leorize | alloc() |
| 14:37:12 | TheLemonMan | smitop, allocShared |
| 14:37:13 | masterm | TheLemonMan: got it |
| 14:37:26 | TheLemonMan | alloc/alloc0 gets you memory from the thread-local heap |
| 14:37:46 | masterm | leorize: so if I understand correctly in this particular example I can just pass a string to pathBuffer and it will get properly resized to bufferSize before being written to? |
| 14:37:59 | TheLemonMan | allocShared gets you memory from the "global" heap (and is jsut a thin wrapper around malloc) |
| 14:38:28 | leorize | masterm: no, a string of appropriate size must be created beforehand |
| 14:38:37 | leorize | see the first line of that function |
| 14:38:48 | FromDiscord_ | <smitop> okay, thanks |
| 14:39:02 | masterm | leorize: ah yes. sorry got it wrong. you're right of course. |
| 14:41:22 | masterm | so how do I create an empty string value that has an appropriate internal buffer capacity? is there a call like C++'s reserve()? |
| 14:41:41 | TheLemonMan | newString |
| 14:42:15 | leorize | well it's in, uh, the first line of that example :P |
| 14:42:57 | masterm | oof. I need a coffee or something :D |
| 14:43:36 | masterm | anywa, thanks guys! :) |

| 15:11:23 | FromGitter | <tim-st> This is a nim bug? https://github.com/pragmagic/vscode-nim/issues/99#issuecomment-427658155 |
| 15:12:50 | FromDiscord_ | <smitop> \n represents a newline |
| 15:12:58 | TheLemonMan | compiles just fine here |
| 15:13:28 | FromGitter | <tim-st> The question was, why is '\n' marked in a red color? |
| 15:13:38 | FromGitter | <tim-st> The answer was, it comes from nim compiler |
| 15:14:23 | narimiran | well, `\n` gets some underline, but it is not the same underline like when you have some error |
| 15:15:02 | FromGitter | <tim-st> '\n' gets the color for "something is inside '...' that is not allowed" although it is allowed |
| 15:15:22 | FromGitter | <tim-st> try '\t' this has a good color |
| 15:15:40 | narimiran | yeah, i've seen that underline in my code, but i have just ignored it |
| 15:16:18 | FromGitter | <tim-st> I ignored it too, I just wondered if that really comes from nim compiler? |
| 15:16:31 | FromGitter | <tim-st> I thought there is a grammar definition in vscode |
| 15:17:23 | narimiran | now i've tried to have more than one character inside of the single quotes: it is the same color/underline, but only for even number of characters |
| 15:18:11 | FromGitter | <tim-st> yes, there I have seen this too, so there is a bug in vscode plugin or nim compiler; the auhor says it comes from nim, so I'm wondering |
| 15:23:40 | * | PMunch quit (Remote host closed the connection) |
| 15:27:28 | FromGitter | <tim-st> Latest nim-vscode update from today supports code formatting using nimpretty :) |
| 15:38:32 | FromGitter | <tim-st> I thought about the following: add `r'...'` syntax to `unicode` module, so a Rune can be created like a char without always using "...".runeAt(0); would this work for char syntax too? |
| 15:39:23 | leorize | afaik that syntax only work for strings |
| 15:39:50 | FromGitter | <tim-st> and for regex with re"" so maybe also for char |
| 15:40:01 | FromGitter | <tim-st> would be really cool |

| 15:41:07 | leorize | tim-st: I think you can just add a space between `r` and `'...'` |
| 15:41:16 | leorize | exploit the command calling syntax ;) |
| 15:41:57 | FromGitter | <tim-st> no that wouldnt work, because inside '..' only 0..255 is allowed while Rune allows 0..0x10ffff |
| 15:42:18 | FromGitter | <tim-st> (uint8 vs int32) |
| 15:43:05 | FromGitter | <tim-st> so compiler change would be needed or "" intead of '' |
| 15:55:15 | leorize | it will never happen |
| 15:55:22 | leorize | nim source it utf-8 only |
| 15:55:35 | leorize | s/it/is/ |
| 15:56:14 | leorize | so if you want to write some big char you'll still need strings |
| 15:57:58 | FromDiscord_ | <treeform> error: "could not load: kernel32" There is no kernel32 on linux right? Its a windows thing? How did it get here? |

| 17:20:31 | FromGitter | <kayabaNerve> smitop: I've never had a problem :thinking: |
| 17:21:23 | TheLemonMan | iirc the main one is the fixed numbers of fds it can listen on |
| 17:21:52 | FromGitter | <kayabaNerve> asyncnet has 4 layers. One of these layers has limited powers on Windows, so although you can talk to any layer, you can only safely talk to every layer on non-Windows platforms. |
| 17:22:36 | FromGitter | <kayabaNerve> Because a single layer has limited capabilities on Windows. |

| 22:02:15 | flaviu | timotheecour: I've replied in that thread. it's hard to post long responses in IRC |
| 22:04:16 | flaviu | but re. everything should be an iterator: that'd be nice, but I don't think nim is the place for it. the concepts of inline & closure iterators really complicate things. |
| 22:07:05 | flaviu | haskell can do stuff like this because "pure" and "sufficiently smart compiler"; python can do stuff like this because performance doesn't matter and everything is a closure iterator, but for Nim, which focuses heavily on performance, this would be quite a bit harder |
| 22:11:35 | FromGitter | <timotheecour> it could operate on 1st match only, and use an extra index to indicate start of position at which we’re interested in matching/replacing |
| 22:14:14 | FromGitter | <timotheecour> actually ya, that’s something weird with nre API: we have find/findAll but somehow just replace which actually means replaceAll |
| 22:17:46 | FromGitter | <timotheecour> also, all these API’s (not just nre) would become a lot cleaner if/once we have string slices (I built these based on nim-range), which would avoid the need for `start` index as well as `captureBounds` vs `captures`: it’d be as efficient as can be while having a cleaner, simpler API. |
| 22:19:53 | flaviu | timotheecour: re. slices: agreed. I was actually thinking about exactly that while writing my response about orthogonality. The slice visited is an orthogonal concern to actually performing the operation, so it could be cleanly separated into an independent component. |
| 22:21:27 | flaviu | and the find/findAll/replace/replaceAll is an interesting point. I'll admit that I haven't thought about that |
| 22:22:02 | flaviu | how everyone else does it is so embedded in my mind that I didn |
| 22:22:06 | FromGitter | <timotheecour> the funny thing is it’s not even hard to do write this sliced string; the only tricky part is all the stdlib would have to be adapted to take advantage of it (wherever string is taken) maybe a proof of concept could be done as a nimble package to showcase efficiency gains. |
| 22:22:17 | flaviu | 't even consider the asymetry. like look at JS's find/replace |
| 22:23:07 | FromGitter | <timotheecour> i think replaceFirst would be an “ok” workaround. |
| 22:23:50 | flaviu | yup. I'd even go as far as deprecating replace & find in favor of replaceAll and findFirst |
| 22:24:11 | flaviu | are concepts usable in Nim? I haven't kept up recently. Could we have a string concept? |
| 22:24:33 | FromGitter | <timotheecour> so long u can enforce compiler error it could be ok; but I’m not sure we can enforce that |
| 22:24:46 | FromGitter | <timotheecour> yes |
| 22:31:52 | FromGitter | <timotheecour> actually string is not a keyword so one could imagine redefining `string` as a concept in some modules |
| 22:34:33 | flaviu | well, string* {.magic: String.} |
| 22:35:11 | * | smitop joined #nim |
| 22:36:28 | FromGitter | <timotheecour> what I meant is it can be redefined in a module; but ya, probably best to give string concept a different name. |
| 22:38:58 | FromGitter | <timotheecour> a practical solution would be: ⏎ ⏎ 1) keep string as is ⏎ 2) introduce a string slice concrete type as dstring (or whatever other name) ⏎ 3) introduce a String concept equal to string|dstring ... [https://gitter.im/nim-lang/Nim?at=5bba8b02c08b8b3067ea4e2b] |

| 22:42:53 | flaviu | hmm. I have to step away now, but yeah, that'd be cool to explore. I'll take a look at that at some point. |
