| 19:03 | < celticminstrel> | Hmm. Is it possible to have a terminal-like application using Unicode characters? |
| 19:21 | <@McMartin> | On Windows, link your console app in Unicode mode, use LPCTSTRs. |
| 19:31 | < celticminstrel> | I was hoping for portable. The program in question is actually a Windows console application using codepage 437 characters. |
| 19:49 | < celticminstrel> | And I want to port it to something that works on Mac. Is there no simple way to do this? |
| 19:50 | < celticminstrel> | I was going to try curses, but its alternate character set is extremely limited... |
| 20:02 | <@McMartin> | Handling unicode is the terminal's job, not yours. =/ |
| 20:05 | | Kazriko [kaz@Nightstar-e09690fa.client.bresnan.net] has joined #code |
| 20:05 | | mode/#code [+o Kazriko] by Reiver |
| 20:05 | < celticminstrel> | Huh? |
| 20:06 | <@McMartin> | On Mac, as with all Unix-like terminals, the code page is set by the terminal emulator, not by the application running inside it. |
| 20:06 | <@McMartin> | In the simplest case, just emit UTF-8 in the first place and it'll probably Just Work on a Mac. |
| 20:07 | < celticminstrel> | Hm. I could try that. |
| 20:07 | < celticminstrel> | I remember some mention in this room of the Ncurses wide-character support lacking in some way. |
| 20:08 | <@McMartin> | Yes |
| 20:08 | <@McMartin> | It doesn't really have it. |
| 20:08 | <@McMartin> | But you can pretend by emitting it pre-formatted. |
| 20:08 | < celticminstrel> | What does that mean? |
| 20:08 | <@McMartin> | You will in all cases probably have to call setlocale(LC_ALL, "") first. |
| 20:10 | <@McMartin> | As in, writing out a UTF-8 byte stream with putch |
| 20:10 | <@McMartin> | Instead of having some opaque way of representing Unicode strings |
| 20:14 | < celticminstrel> | So, for two-byte characters I would need to call putch twice. And colours and stuff would still work? |
| 20:16 | <@McMartin> | Seems to have. |
| 20:16 | <@McMartin> | (nfrotz does this) |

| 20:31 | < celticminstrel> | I'm guessing it's not a good idea to use cout with ncurses? |
| 20:33 | <@McMartin> | s/cout/anything but the curses printw-style commands/ |
| 20:34 | < celticminstrel> | ...printw-style commands? You mean addstr? |
| 20:34 | < celticminstrel> | (and its relatives) |
| 20:34 | < celticminstrel> | ...wait. |
| 20:34 | < celticminstrel> | Never mind, I guess. |
| 20:35 | <@McMartin> | That's a relative |
| 20:35 | <@McMartin> | Basically, if you have a curses window around, only use curses to do output. Otherwise, your output will not work right. |
| 20:35 | < celticminstrel> | It worked fine when I originally did it with conio. |
| 20:36 | <@McMartin> | conio isn't maintaining virtual cursors outside of the terminal itself, though. |
| 20:36 | < celticminstrel> | Ah. |
| 20:37 | < celticminstrel> | I also recall curses giving an error if I try to draw past the end of the screen, whereas conio just scrolled the screen up. |
| 20:51 | < celticminstrel> | Um, what? How does "cSpace=='\xE2' " generate a "comparison always false" warning? |
| 20:51 | < celticminstrel> | (cSpace is an unsigned char.) |
| 20:52 | < celticminstrel> | ...unless it somehow thinks it is a multichar constant. |

| 21:54 | | * gnolam hugs science. |
| 21:57 | < gnolam> | (I'm about to argue against character-by-character printing in RPGs, and I just realized I have actual scientific arguments (messes with the human reading process) complete with references to back me up) |
| 21:57 | < gnolam> | I knew that cognitive psychology course was going to come in handy one day! |
| 21:59 | < Namegduf> | Haha, that's awesome. |
| 22:00 | <@Vornicus> | I'm pretty sure the original reason is that there wasn't enough power to handle extents for non-monospaced fonts on old old old consoles. |
| 22:05 | <@Vornicus> | Which meant that for programs that wanted it -- early RPGs come to mind because proportional fonts tend to be easier to take in large amounts of text with -- you'd /have/ to do it character by character or you wouldn't be able to get the first words in for a rather long time. |
| 22:15 | < celticminstrel> | Huh? What are we talking about? |
| 22:16 | | Orthia [orthianz@Nightstar-993ef087.xnet.co.nz] has joined #code |
| 22:16 | <@Vornicus> | how, in many RPGs, the words come in letter by letter. |
| 22:18 | < celticminstrel> | Ah. I think I see what you mean now. |
| 22:19 | < Tarinaky> | There is one advantage though. |
| 22:19 | < Tarinaky> | It makes it harder to click past it by accident. |
| 22:20 | < Tarinaky> | But that could probably be achieved with a 0.5 second pause before it starts registering input again. |
| 22:20 | <@ToxicFrog> | Tarinaky: so include a summary button like in FF12. |
| 22:20 | < gnolam> | Instead, you pay no attention to /any/ of the text out of frustration. |
| 22:20 | < Tarinaky> | Long enough for someone to go "Oh shit. I wanted to read that." |
| 22:20 | < gnolam> | The correct solution is conversation logs. |
| 22:20 | <@ToxicFrog> | Also, if you develop a game and put pauses in it like that I will hunt you down and choke you to death with your own game script |
| 22:20 | < Tarinaky> | ToxicFrog: I know. |
| 22:20 | < celticminstrel> | ...wait. There's seriously no wifstream::open(wchar_t*) ? :O |
| 22:21 | < celticminstrel> | That doesn't make any sense! |

| 22:25 | < celticminstrel> | Why wouldn't wifstream have a an open function that takes wchar_t* !? |
| 22:30 | < gnolam> | Hee. |
| 22:30 | < Tarinaky> | I'm guessing when it was written wchar file systems were rare? |
| 22:31 | < celticminstrel> | Well, it's actually a typedef of basic_ifstream<wchar_t>... and I'm pretty sure the templated version was developed due to the introduction of wchar_t or somesuch. |
| 22:31 | < celticminstrel> | The whole purpose of wifstream is to handle wide character streams. |
| 22:32 | < celticminstrel> | But I guess the open function's parameter type is not the template parameter. |
| 22:34 | < gnolam> | I'm watching a presentation video for a robot a friend is working on. Among other things, it does object recognition. |
| 22:34 | < gnolam> | In the video, it has three objects on a table in front of it - a matchbox, a can of coca-cola and a toy police car. They also have a voice synthesizer hooked up to it giving status updates. |
| 22:35 | < gnolam> | After identifying the different objects, it then sees if it can locate them again. |
| 22:36 | < gnolam> | Voice: "Target selected. Examining target. Coke found." |
| 22:36 | < gnolam> | Voice: "Looking for police car..." |
| 22:37 | < gnolam> | They've apparently accidentally made the world's first coke-head robot. :D |
| 22:37 | < celticminstrel> | Uh... "format argument not a string type"? It's wchar_t*, how is that not a string type? |
| 22:38 | <@McMartin> | You need the wide character version of printf, most likely. |
| 22:39 | < celticminstrel> | No, I'm trying to tell GCC that this function is a printf-style function. |
| 22:40 | < celticminstrel> | It's basically wprintf, but using curses output instead of standard output. |
| 22:41 | < gnolam> | So what format is the format string in? |
| 22:41 | < celticminstrel> | int putstr(const wchar_t*,...) __attribute__(( format(printf,1,2) )); |
| 22:41 | < celticminstrel> | There's the prototype. |
| 22:41 | < gnolam> | And are you passing a wchar literal? |
| 22:42 | < celticminstrel> | Yeah. But the error occurs at the prototype. |
| 22:43 | <@McMartin> | Can you make it be format(wprintf)? |
| 22:44 | < celticminstrel> | Hm. Let me try that. |
| 22:44 | < celticminstrel> | Nope. "'wprintf' is an unrecognized format function type" |
| 22:46 | <@McMartin> | I haven't messed much with gcc attributes here. |
| 22:47 | <@McMartin> | I would consult The Great Gizoogle. |
| 22:47 | < celticminstrel> | I guess the worst case is that the compiler simply can't type-check the format arguments. |
