| 00:38:54 | FromGitter | <zacharycarter> def-pri-pub: nothing beyond what I have in my head which is get it to a state where it can be used for making a game |
| 00:38:58 | FromGitter | <zacharycarter> do you have some ideas? |
| 00:41:00 | def-pri-pub | eh, more general ideas for Nim that don't really exist, that would mainly help with game develompent, but useful for other things. |
| 00:42:06 | FromGitter | <zacharycarter> I gotcha |
| 00:42:25 | dom96 | demi-: yes, take a look at what the .sh script does |
| 00:42:28 | FromGitter | <zacharycarter> I think zengine needs examples |
| 00:42:44 | FromGitter | <zacharycarter> because it can most likely do a lot of what raylib can already |
| 00:45:09 | def-pri-pub | E.g. I don't think there's a really good geometry & maths library out there. |

| 05:11:19 | dozn | Araq, thanks for your help with the {.raises.} earlier, I've sucked it up and simply created a main proc which is instantly called, in order to ensure I've caught everything, I believe it's working well =) |

| 05:37:27 | dozn | Araq, also, regarding where we should see the auto-implied {.raises[].}, it would be great if <insert IDE plugin> (I'm using VSCode) would show which exceptions bubble up whenever you hover over a function. I'm new to exceptions as a method of error handling as well, so perhaps this isn't required for some reason which I'm obviously oblivious to =b |
| 05:38:32 | dozn | Actually, even if I manually insert a {.raises[].} pragma, that plugin doesn't display it on the tooltip, although it displays everything else ({.gcsafe, locks: <unknown>.}, etc.}) |

| 06:52:11 | dozn | def-, So I can chain whilst there's conflicting functions |
| 06:52:16 | def- | dozn: a module could re-export the identifier, or you could import the original |

| 06:52:55 | dozn | Yeah, I did make the example confusing, due to me having a "debug" module =b |

| 06:53:16 | def- | If you care about binary size: https://hookrace.net/blog/nim-binary-size/ |
| 06:53:19 | dozn | Sorry, that was just a random example, not an exact issue I have |
| 06:53:41 | dozn | I'm content with the nim binary size, in fact, more than content, I'm ecstatic |
| 06:53:46 | dozn | =) |
| 06:54:06 | dozn | I really hope I have some time in a few months to write some tutorials/documentation |
| 06:56:25 | dozn | Part of the file size discrepancy is almost certainly due to not dynamically linking SSL, although I'm unsure of what Rust and Go does specifically for it, I believe Go does not by default include SSL |
| 06:56:45 | dozn | not statically linking SSL* |
| 06:56:57 | def- | sounds like a bad idea to statically link ssl |
| 06:57:19 | def- | need to update your application with each openssl vulnerability |
| 06:57:37 | def- | but with dyn libs you run into problems of different versions being available on linux distros |
| 06:57:51 | dozn | Yar, I've gone back and forth for years, but I've finally settled on static binaries |
| 06:58:09 | dozn | I just watch every dependency and rebuild when need be |
| 06:58:40 | dozn | I actually built an app which did this for me, I wonder if I still have it hanging around.. |
| 06:58:58 | dozn | Fuck, I think I wrote it in PHP 15 years ago hahaha |
| 07:00:42 | dozn | even libssl.a is only ~600->700kb |
| 07:03:27 | dozn | http://midipix.org/#sec-midipix looks neat, I wonder if it would allow me dynamically link musl on Windows... |
| 07:03:44 | dozn | Ctrl+F musl |
| 07:03:47 | def- | why would you want to do that? |
| 07:04:29 | dozn | I just think it's twisted haha |
| 07:04:42 | def- | I would understand it if you're writing straight in C |
| 07:04:52 | def- | But Nim has reasonable Windows support |
| 07:05:05 | dozn | Do nim binaries include a C std replacement? |
| 07:05:20 | dozn | Or does it dynamically link to some Windows C backend |
| 07:05:29 | dozn | (my knowledge regarding Windows is incredibly limited) |
| 07:05:31 | def- | dyn link against system's c stdlib |
| 07:05:54 | dozn | Any idea what that would be on Windows, or shall I do some Googling? =D |

| 08:41:49 | FromGitter | <timmyjose> I am used to working with Far Manager on Windows. so it would be lovely to have support for Nim in Far Manager,. Maybe I can consider working on a plugin myself in the near future - that would be an interesting project :-) |

| 08:47:28 | dozn | running functions on the HTML* |
| 08:48:17 | dozn | Oh sorry, I'm not running a server, I'm running a client |
| 08:48:22 | dozn | Web scraping |
| 08:50:02 | dozn | Right now I'm just using `httpclient.newHttpClient().getContent(url).newStringStream.parseHtml`, I want to throw that (using a concurrency primitive) into a longer proc which also does other things (perhaps spawn off more concurrent things) |
| 08:50:53 | dozn | I'm assuming I want asyncdispatch, but I've never used a language with async before, so asking to be sure there's no better methods. |
| 08:52:05 | * | Matthias247 joined #nim |

| 10:43:19 | def- | I just looked at the implementation |

| 11:49:00 | couven92 | yeah okay, that makes more sense |
| 11:49:21 | Araq | oh and don't hack the implementation together with the existing replace |
| 11:49:30 | Araq | a single pass over the input string please |
| 11:49:45 | couven92 | yeah... avoid allocations, got it! :) |
| 11:49:58 | Araq | this is required for correctness anyway, think about x.multiReplace(("a", "b"), ("b", "a")) |
| 11:50:36 | Araq | that needs to swap a's and b's |
| 11:51:32 | couven92 | yeah... thinking: iterate over the input at each character see if it starts with one of the replacement tuples and then replace |

| 14:08:45 | couven92 | Araq, https://github.com/nim-lang/Nim/pull/6193 |
| 14:10:03 | couven92 | Araq, But I also need some help... I tried first to preallocate result with the length of s with `result = newString(s.len)` but then add didn't seem to add the replacement strings? |
| 14:10:31 | FromGitter | <TiberiumN> AFAIK if you preallocate a string or sequence you need to modify it by index |
| 14:10:37 | FromGitter | <TiberiumN> not by doing "add" |
| 14:10:44 | def- | couven92: probably a \0 byte inbetween in your string |
| 14:11:02 | couven92 | hmm... okay |
| 14:11:26 | def- | @TiberiumN No, you can preallocate, and then use add. |
| 14:11:37 | FromGitter | <TiberiumN> I know |
| 14:11:53 | FromGitter | <TiberiumN> but first chars then would be empty |
| 14:12:00 | def- | Strings are just a bit dangerous because they have both a length and also end on \0 byte |
| 14:12:10 | def- | but that's only for strings, not sequences |
| 14:14:45 | couven92 | def-, so how do I do it? https://github.com/couven92/Nim/blob/strutils-multireplace/lib/pure/strutils.nim#L1557 |
| 14:15:55 | def- | couven92: what's your goal? |
| 14:16:49 | couven92 | I have result and it should possibly be preallocated with s.len, then i add replacement parts to it as I iterate through s |
| 14:17:17 | def- | but what do you want to be the content of result? |
| 14:17:33 | def- | what are "replacement parts"? |
| 14:17:47 | def- | Ah, I think I understand |
| 14:17:52 | subsetpark | Araq : can't that just overload on the signature of strutils.replace? |
| 14:18:00 | def- | use newStringOfCap() |
| 14:18:44 | couven92 | def-, okay... but what if my new string actually gets longer than the original length of s? Should I realloc then? |
| 14:18:53 | def- | no, that happens automatically |
| 14:19:01 | couven92 | Ah! great! :) |
| 14:19:05 | def- | if you just add until the initially allocated size, no reallocs happen |
| 14:19:13 | def- | if you add more, it will grow automatically |
| 14:19:41 | couven92 | very good! exactly what I want... I misunderstood Cap in newStringOfCap :P |
| 14:20:02 | def- | Yeah, it's just its current capacity, not the maximum capacity it can have |
| 14:21:13 | couven92 | def-, great! thanks! works like a charm! :) |
| 14:24:23 | couven92 | okay, Araq https://github.com/nim-lang/Nim/pull/6193 is ready for review :) |

| 18:46:33 | FromGitter | <cyberlis> i want compare to sha1 hashes |
| 18:46:39 | FromGitter | <TiberiumN> well just compare them as strings? |
| 18:46:40 | FromGitter | <cyberlis> what is begger |
| 18:47:00 | FromGitter | <TiberiumN> what do you mean "bigger"? |
| 18:47:04 | FromGitter | <TiberiumN> you can't get file size from sha1 |
| 18:47:19 | FromGitter | <cyberlis> hashes a big numbers |
| 18:47:45 | FromGitter | <cyberlis> that is why you can compare them |
| 18:48:20 | FromGitter | <TiberiumN> well you can compare them as strings too |
| 18:49:04 | FromGitter | <cyberlis> you think it will give the same result? i will check it in python |
| 18:49:16 | FromGitter | <TiberiumN> why not? |
| 18:49:22 | * | Trustable quit (Remote host closed the connection) |
| 18:49:27 | FromGitter | <TiberiumN> if hashes are different as strings they'll different as numbers |
| 18:49:37 | FromGitter | <TiberiumN> well there's pure-nim bignums, but it's not very fast AFAIK |
| 18:49:41 | couven92 | @cyberlis, Uhm no! Hashes are binary blobs with no meaning at all, except that you can sequence compare to hashes. If they're not sequence equal the hash origin are different from each other |
| 18:50:20 | FromGitter | <TiberiumN> I don't really understand why do you need big numbers, but there is - https://github.com/def-/nim-bigints |
| 18:50:41 | FromGitter | <TiberiumN> but I think you don't need them |
| 18:50:42 | FromGitter | <TiberiumN> at all |
| 18:51:28 | FromGitter | <cyberlis> Wikipedia |
| 18:51:29 | FromGitter | <cyberlis> A SHA-1 hash value is typically rendered as a hexadecimal number, 40 digits long. |
| 18:51:33 | FromGitter | <cyberlis> number |
| 18:51:38 | FromGitter | <TiberiumN> well "typically" |
| 18:51:43 | FromGitter | <TiberiumN> it's just a matter of the preference |
| 18:51:49 | FromGitter | <cyberlis> hexadecimal number |
| 18:51:59 | FromGitter | <TiberiumN> you can have it as bytes |
| 18:52:09 | FromGitter | <cyberlis> one number can be bigger than other |
| 18:52:12 | FromGitter | <TiberiumN> can you explain what are you trying to achieve? |
| 18:52:14 | FromGitter | <cyberlis> is it true? |
| 18:52:22 | couven92 | @cyberlis No! Wrong, 40 hex digits to represent a 20-byte arre |
| 18:52:43 | couven92 | *array |
| 18:53:04 | FromGitter | <cyberlis> ok i see |
| 18:53:06 | FromGitter | <cyberlis> thanks |
| 18:57:22 | couven92 | @cyberlis, also, if you'd actually convert a SHA-hash to a value it would be enourmously large! Remember 64-bit values go up to ~18 trillion, A 20-byte numerical value would stretch over 160 bits! And with each bit you double the possible values... It's enomous! |

| 19:57:52 | salewski | What I really want to use in the macro is something like "var s = CX" |
| 19:58:14 | salewski | where CX is a string constant. |
| 19:59:45 | salewski | I thought that would be easy. But maybe it is easier putting that string constant in a hash table |
| 20:00:07 | salewski | and accessing that hash table from within the macro. |
| 20:01:18 | FromGitter | <singularperturbation> so you're passing in the name of the constant to the macro and then setting the var equal to that variable? |
| 20:01:46 | FromGitter | <singularperturbation> can you pass in the const as a value to the macro instead? and then do quasi-quoting on the expression that's passed in to the macro ? |
| 20:02:29 | FromGitter | <singularperturbation> only other thing I can think of is building a `newIdentNode` from the string passed in and playing around with that? |
| 20:03:34 | salewski | The user calls the macro like "connect("draw", myfunc, myarc)" |

| 20:06:23 | FromGitter | <TiberiumN> do something with this string and generate new const statement? |

| 20:11:34 | FromGitter | <TiberiumN> proc `!`(s: string): NimIdent {..} ⏎ constructs an identifier from the string s |

| 21:12:44 | FromGitter | <zacharycarter> hrm |
| 21:13:13 | FromGitter | <zacharycarter> let me point you to some code |
| 21:14:24 | FromGitter | <zacharycarter> nevermind - let me just explain, left shift and left alt can be used to rotate the camera when held down together |
| 21:14:24 | FromGitter | <zacharycarter> mouse wheel zooms in and out |
| 21:14:39 | FromGitter | <zacharycarter> left shift by itself pans |
| 21:14:58 | FromGitter | <zacharycarter> the keeping your mouse within the screen can be easilyturned off |

| 21:16:19 | def-pri-pub | My personal opntion, is that by default the mouse shouldn't be contained to the screen. |
| 21:16:27 | FromGitter | <zacharycarter> I agree |
