| 10:00:45 | gokr | Hey |
| 10:01:37 | gokr | Last night I tried compiling your wxnim samples on OSX, but... got stuck somewhere with header files etc. It was talking about me having to run some config program to generate compiler options I think. |
| 10:02:16 | Araq | yeah, this needs a nim script :-) |

| 10:06:07 | NimBot | nim-lang/Nim devel 0320c0c Araq [+0 ±5 -0]: fixes DLL hell on Windows |
| 10:06:31 | gokr | Sooo... was looking at wx vs Qt, and ... both use native stuff on OSX and Windows, but one major difference is that Qt renders its own on X11, while wx relies on GTK. |
| 10:06:36 | yglukhov | Wow, DLL hell is finally fixed! ;) |
| 10:06:45 | gokr | That kinda tips it over to wx for me personally, for desktop platforms. |
| 10:07:05 | Araq | warning: commit messages might not reflect reality. |
| 10:07:11 | * | tankfeeder joined #nim |
| 10:07:22 | gokr | But... for mobile, its still kinda bleak. I was hoping Qt used native on mobile, but nope. In fact, |
| 10:07:50 | gokr | mobile is darn tricky - iOS needs Obj-C and Android needs Java. Technically messy. |
| 10:08:18 | Araq | mobile is as big of a fuckup as is web dev |
| 10:09:14 | gokr | Yeah. So... pure Urho based UI looks definitely like an option :) |
| 10:09:46 | Araq | I wonder whether i'm allowed to run our software on my iPad or only in the simulator until apple approved my signings and shit |
| 10:10:43 | gokr | I guess you can run it on the iPad ... somehow. But I know too little. I am actaully exchanging emails with Hilaire who makes Dr Geo, about his experience on that topic. |
| 10:11:06 | Araq | so with install_nimble.nims it's official. I will never write any bat/sh scripts anymore :-) |
| 10:11:06 | gokr | He makes http://www.drgeo.eu |

| 21:14:33 | Araq | new(x) |
| 21:14:35 | Araq | echo notNil(x) |
| 21:16:01 | OnO | aha... you have declared it as ref Blah not nil |
| 21:16:10 | OnO | why var: ref Blah is not sufficient? |
| 21:17:08 | OnO | why it has to be var: ref Blah not nil? |
| 21:18:21 | Araq | cause the checker doesn't even track ordinary 'ref' |

| 22:08:47 | Araq | OnO: any idea of how much code this will break? I cannot imagine the compiler bootstraps without a huge amount of work |
| 22:09:09 | OnO | so far it breaks mostly on cstring handling |
| 22:10:13 | OnO | the problem is that somehow cstringArray is array[0...Dummy, cstring or nil] for example |
| 22:10:21 | OnO | but I cannot arr[i] != nil easily |

| 22:32:15 | OnO | hmm... I think I found a but |
| 22:32:17 | OnO | bug |
| 22:33:05 | OnO | declaring PType = ref Type and var a: array[1..2, PTest not nil] makes a[1] to be type PType, not PType not nil |
| 22:38:30 | * | NimBot joined #nim |
| 22:41:02 | OnO | okay, this is bug in typeToString not showing "not nil" for cstring not nil or PType not nil |
| 22:42:00 | Araq | ah yeah, quite possible |
| 22:43:03 | gmpreussner | i'm converting some odd C code that declares various enums, but then also has some functions whose parameters accept a combination of values from different enum types, i.e. foo(EnumA_ValX | EnumB_ValY). is there any good way to model this in Nim other than making those parameters to integers and cast the enum values to integers before OR'ing them? |
| 22:43:36 | gmpreussner | i.e. is there some way to create compound enum types consisting of different enum types, or what would be the best way to model this? |
| 22:44:00 | gmpreussner | my best guess would be to drop enums altogether and just make everything consts |
| 22:44:40 | gmpreussner | i hope my explanations make sense - and yes, i'm aware that the C API is questionable :) |
| 22:45:00 | Araq | sometimes you can do this: |
| 22:45:05 | Araq | type foo = enum |
| 22:45:06 | * | boopsies is now known as boopsiesisaway |
| 22:45:10 | Araq | a = 0, |
| 22:45:13 | Araq | b = 1, |
| 22:45:50 | Araq | er, a = 1, b = 2, ab = 3 # a|b |
| 22:45:51 | federico3 | c = 2, |
| 22:46:29 | Araq | usually you just map it to some consts though. |
| 22:46:54 | gmpreussner | how do i get the function parameters type safe though? |
| 22:47:18 | Araq | with a distinct int perhaps |
| 22:47:55 | gmpreussner | for example, i have: proc foo(e: EnumA); proc bar(e: EnumB); proc foobar(e: ???); foobar(EnumA.X or EnumB.Y) |
| 22:48:49 | gmpreussner | the C API just uses an int for foobar's parameter |
| 22:49:02 | gmpreussner | i want to turn this shitty C API into something more sane in Nim :) |
| 22:49:24 | Araq | just a single distinct int for the values and borrow the 'or' operator |
| 22:49:29 | Araq | *use a |
| 22:49:36 | * | ^aurora^ quit (Ping timeout: 264 seconds) |
| 22:49:50 | gmpreussner | but then i can't namespace the values, can i? |
| 22:50:31 | Araq | you can put them in their own module |
| 22:50:44 | gmpreussner | yikes... true |
| 22:51:21 | gmpreussner | maybe i'll just stick with casting everything to integers then |

| 23:05:52 | Araq | hrm "use {.anchor.} for base methods; anchorless methods are deprecated" |
| 23:06:04 | Araq | maybe Jehan_ is right and it should just be called .base then? |
| 23:06:39 | * | Ven joined #nim |
| 23:07:11 | Jehan_ | Don't think it's right or wrong, it's more what people find intuitive or not, and I've learned that just because I personally find something intuitive, that doesn't hold for everybody else. :) |
| 23:07:23 | * | umurgdk joined #nim |
| 23:12:09 | * | NimBot joined #nim |
| 23:12:21 | Araq | well .base is also shorter |
| 23:23:25 | Araq | hrm this also allows a new feature |
| 23:23:51 | Araq | method m(x: A) {.base.} |
| 23:24:24 | Araq | method m(x: B) {.base.} |
| 23:24:35 | Araq | method m(x: C) |
| 23:26:04 | Araq | nah |
| 23:26:16 | Araq | I thougt it can be used to cut off A's method m |
| 23:30:05 | Jehan_ | Araq: Is there a reason why GC_init() for the Boehm GC is only explicitly called for OS X? |
| 23:30:54 | Araq | who knows, iirc the docs said it's the only platform where it's required |
| 23:32:26 | Jehan_ | I was just wondering if it's intentional. It seems to cause a duplicate initialization bug on Linux. |
| 23:32:44 | Jehan_ | And there only with multiple threads. |

| 23:43:38 | Jehan_ | Hmm, looking at the documentation, I think it's just misleading. And it seems to be definitely unsafe to omit it in the multi-threaded case. |
| 23:56:50 | Jehan_ | Submitted a PR to fix this. |
| 23:57:08 | Jehan_ | At the very least, it stops the crash on VirtualBox+Ubuntu. :) |
| 23:57:13 | Araq | thanks :-) |
| 23:57:35 | Araq | now if only you could tell me how to fix my threadpool ;-) |
