| 05:37:56 | gmpreussner | awsteele: sounds like you're passing a BiggestInt to an int. you could cast to int (With possible loss of data) |
| 05:38:54 | awsteele | i'm happy with loss of data (because it's json that will only contain values < 100), but i wasn't sure how nicely it would play with truncating |
| 05:40:34 | gmpreussner | just cast to int then |
| 05:40:40 | awsteele | thanks :) |
| 05:40:42 | gmpreussner | are you running on 32-bit? |
| 05:40:47 | awsteele | 64 |
| 05:40:57 | gmpreussner | Bigint = int then, so no loss of data |
| 05:41:42 | gmpreussner | but who knows, maybe BiggestInt changes to 128bit in the future :) |
| 05:41:57 | awsteele | gotta future proof! |
| 05:42:10 | gmpreussner | you know, when we have those 1000 core cpus that were promised to us years ago |
| 05:42:58 | gmpreussner | int64 ought to be enough for anyone though (TM) |
| 05:43:12 | awsteele | not enough for ipv6! |
| 05:43:25 | endragor | I wish Nim didn't have those platform-dependent types... they're annoying, and trying to avoid them is also annoying, because you have to cast to int whenever you use anything from stdlib |

| 10:12:43 | krux02 | I am programming with macros, and at the moment the error I get is "SIGSEGV: Illegal storage access. (Attempt to read from nil?)" without any additional information. Why doesn't it show some information where it failed? |
| 10:15:55 | flyx | krux02: because it's a segfault, i.e. the compiler runs into a non-recoverable error. you can try and compile your code with ./koch temp c yourcode.nim |
| 10:18:31 | endragor | @krux02 that typically happens when your macro outputs invalid AST. put `echo treeRepr result` at the end of the macro code and try to determine what's wrong with it. Another typical reason is dereferencing nil in your macro code. |

| 10:57:21 | Araq | there are LOTS and lots of checks -.- |
| 10:57:49 | Araq | and I did run thousands of lines of code at compile-time without any problems |
| 10:58:12 | Araq | except compilation speed, so I did things differently via staticExec |

| 15:44:28 | Araq | if you mean "koch temp" by "just modified and built" |
| 15:44:32 | Araq | then yeah. |
| 15:44:41 | Araq | "koch temp" produces nim_temp |
| 15:44:49 | Araq | do 'koch boot -d:release' |
| 15:44:55 | Araq | and then the tests use the new nim |
| 15:45:27 | Johz | Will having another nim on the path confuse things at all? |
| 15:45:40 | Johz | Because I'm using koch boot, albeit not in release mode |

| 21:53:33 | dom96 | heh, in all seriousness it's a bit hard to do. I don't want to sound too negative about Nim in the book, since it is a book that is meant to encourage you to learn Nim. |

| 21:55:40 | dom96 | The biggest problem is that it's not as mature as other languages, but that will improve with time. |
| 21:56:50 | lokien | immaturity is the biggest flaw? |
| 21:57:15 | dom96 | lokien: that would be awesome! It would be a big honour if you bought Nim in Action as your first ever programming book :) |
| 21:57:33 | dom96 | lokien: pretty much. |
| 22:00:00 | lokien | dom96: and the only issue with the book is the awkward syntax in longer sentences :D |
| 22:00:23 | lokien | uh, or it's a typo |
| 22:00:39 | dom96 | hrm, which part? |
| 22:00:40 | lokien | you forgot to put a word here. so, a wordo |
| 22:01:00 | lokien | "is necessary when interfacing with |
| 22:01:00 | lokien | C libraries and supporting these unsafe features makes Nim a powerful systems programming language." |
| 22:01:14 | lokien | shouldn't it be "which makes Nim a powerful..."? |
| 22:01:19 | * | filwit joined #nim |
| 22:01:36 | lokien | or I'm just weird, I don't know :D |
| 22:01:49 | lokien | (page 6) |
| 22:05:29 | dom96 | Hmm. I think it makes sense. |
| 22:07:03 | lokien | my proposition, or your sentence? |
| 22:09:48 | dom96 | My sentence |
| 22:10:47 | lokien | I didn't say it doesn't make sense, it was just a bit funky. maybe that's because I'm sleepy, sorry :) |
| 22:11:19 | awsteele | I just bought the book. It's the first programming book I've bought too. Well, except TAOCP, but that's just to look pretty on my shelf :) |
| 22:13:04 | dom96 | lokien: I'm sleepy too so I could be wrong too. It's also hard to say, because I wrote it so it makes sense to me. Will look at it in the morning again. |
| 22:13:26 | dom96 | awsteele: Awesome. Thank you! |
| 22:15:40 | lokien | dom96: chat application in chapter 3? with gui, connections and all that stuff? |
| 22:16:26 | dom96 | lokien: CLI but yes :) |
| 22:16:55 | dom96 | It's nowhere near as complex as IRC of course |
| 22:17:11 | lokien | dom96: I'm so hyped right now :D |
| 22:17:44 | dom96 | lokien: Brilliant. Exactly what I was going for :D |
| 22:18:07 | dom96 | Currently working on Chapter 7 which will involve the development of a simple Twitter clone. |
| 22:18:14 | dom96 | Should be pretty fun too |
| 22:19:57 | lokien | but there are still only 3 chapters available? |
| 22:20:43 | awsteele | does nim's dynlib loading respect LD_LIBRARY_PATH? |
| 22:20:58 | dom96 | The others still need to be reviewed by my editor, then I need to make corrections based on his feedback, and once the editor is happy they will be released. |
| 22:21:56 | lokien | oh, okay. good luck with that book, it's really well-written :) |
| 22:21:59 | filwit | is there anyways to make a ``type CArray{.unchecked.}[T] = ptr array[1,T]`` (note the `ptr`) ? |
| 22:21:59 | dom96 | awsteele: IIRC it uses dlopen which respects LD_LIBRARY_PATH. |
| 22:22:46 | filwit | i mean making an unchecked ptr array[] in the same type (it's easy to do with using 2 types).. just wondering |
| 22:27:24 | dom96 | lokien: Glad you think so! :D |
| 22:28:03 | dom96 | filwit: Don't think so |
| 22:28:33 | filwit | dom96: k, thanks |

| 22:36:14 | awsteele | I have libpcre.so in a dir in my LD_LIBRARY_PATH, but I'm still getting "could not import: pcre_free_study" :( |
| 22:36:52 | * | jeffc joined #nim |
| 22:39:06 | lokien | hey, guys, how do you structure your code? do you put it in modules, namespaces? or just separate files? |
| 22:39:06 | def- | awsteele: wrong version of pcre maybe? |
| 22:39:17 | awsteele | ~/libpcre/lib# nm libpcre.so | grep pcre_free_study |
| 22:39:17 | awsteele | 0000000000016aa0 T pcre_free_study |
| 22:39:59 | def- | awsteele: and no 32/64 bit issue either I guess, hm |
| 22:40:36 | awsteele | oh, maybe? i just did the standard "./configure --prefix=..; make; make install" so i would think not |
| 22:40:58 | def- | lokien: each file is automatically a module with its own namespace |
| 22:41:12 | filwit | lokien: in Nim a file *is* a 'module' when it's 'imported' (and you can use 'include' to split modules across multiple files). There are no "namespaces" exactly (although you can use _:typedesc[T] as a first-parameter to associate a proc with a specific type.. which is somewhat similar) |
| 22:41:22 | def- | awsteele: I think there would be a different error in that case |
| 22:41:28 | dom96 | awsteele: maybe it's loading a libpcre.so.3 or libpcre.so.1? https://github.com/nim-lang/Nim/blob/devel/lib/wrappers/pcre.nim#L322 |
| 22:42:04 | awsteele | there is also a libpcre.so.1 in the dir, but it has the same symbols |
| 22:42:13 | awsteele | no libpcre.so.3 though.. |
| 22:42:15 | def- | filwit: why are there no namespaces? |
| 22:42:46 | lokien | thanks def- filwit |
| 22:42:57 | def- | awsteele: you could try running it with strace and check which library is actually opened |
| 22:43:03 | filwit | i misspoke, dom said it better, each 'imported' module is it's own "namespace" |
| 22:43:45 | def- | filwit: alright. I'm not dom though, even though people call me that rather often |
| 22:44:10 | filwit | def-: i know.. i was referring to dom's response right above mine |
| 22:44:54 | * | darkf joined #nim |
| 22:45:08 | awsteele | great idea, def-! i'll try that |
| 22:46:06 | filwit | def-: about the namespaces thing though.. "namespaces" in Nim do work differently than in C++/C#/Java/etc where each Class provides a namespace around it's methods (and therefor can be included/excluded individually.. unlike Nim which is a procedural language where procs are namespaced by the module only) |
| 22:46:39 | filwit | def-: unless you use the _:typedesc[T] trick... which is why I mentioned it as well |
| 22:48:07 | filwit | err.. included/excluded as a package by type-name I mean.. eg, you can "using System.Console" where Console is a Class and you only want to work with it's methods, not the everything from System |
| 22:49:28 | filwit | that's not really possible in Nim... not that's a practical problem or anything, since it's rare you actually don't just want to include the entire module anyways (that's why you packaged it as a module in the first place) |

| 23:36:29 | awsteele | How does this line work for loading a dynlib? https://github.com/nim-lang/Nim/blob/devel/lib/wrappers/pcre.nim#L322 It looks like it's some kind of regex - is it? I see the stdlib_pcre.c file ends up with the three possible filenames as string literals |
