Hrm. Dealing with this climbing animation is going to be a pain.
02:02

Because the animation intrinsically involves changing the player's location.

< Reiv>
I need a script/thingy to remove the newlines from strings in a csv file.
05:27 * Reiv is bamboozled by this.
05:32
<@Derakon>
So there should be no newlines at all?
05:33
<@Derakon>
If that's the case, open the file in vim, and type :%s/\n//g
05:33
<@Derakon>
Then type :wq to close the file.
05:37
< Reiv>
Alas: 1) .csv files need each row of data on a single line. 2) I'm on windows >.<
05:37
< Reiv>
...although there /is/ a linux box accross the room...
05:38
<@Derakon>
For the former, if there's a character you know won't appear in the file ('|', say), you can do :%s/$/| to mark the desired newlines, and then re-insert them after.
05:38
< Reiv>
So if I get the command right I might almost be desperate enough to give it a shot~
05:38
<@Derakon>
Also, you should be able to get vim on Windows.
05:39
< Reiv>
Probably, but these are lab machines,, so
05:44
< Reiv>
...ooh.
05:45
< Reiv>
How can I find a newline using a regex?
05:45
<@Derakon>
\n and \r are the usual suspects.
05:45 * Reiv just got ConTEXT running off a USB stick.
05:45
< Reiv>
blarg, no dice
05:46 * Reiv screams. This is worth 7% of his final grade, and he /can't even start because the data is dodgy/
05:46
<@Derakon>
How much data?
05:47
<@Derakon>
If it's not too much, you could fix it by hand.
05:47
< Reiv>
And the instructions given - "Use Excel for a find&replace" do not work.
05:47
<@Derakon>
Excel probably has a bunch of settings for importing CSVs since there's so many ways to make them.
05:47
<@Derakon>
I know OOO does.
05:47
< Reiv>
I have 648 lines for 274 entries.
05:48
<@Derakon>
Hm. So about fifteen minutes' work, sounds like.
05:48
<@Derakon>
Annoying, but doable.
05:48
< Reiv>
File 1/3.
05:49
<@Derakon>
Ahh.
05:49
< Reiv>
>.>
05:54
< Reiv>
According to Excel, every instance of Alt+010 is fixed on the file.
05:54
< Reiv>
Ha.
05:55
<@Derakon>
How do you tell the difference between a newline in the middle of an entry and one at the end?
05:55
<@Derakon>
Count the commas?
05:57
< Reiv>
Newline in the middle is inside a string.
05:58
<@Derakon>
Ah, so your delimiter is properly ","
05:58
<@Derakon>
(That is, a comma surrounded by quotation marks)
05:58
< Reiv>
data,"data",data,"Data \n data2",\n
05:58
<@Derakon>
Oh.
05:59
<@Derakon>
I was about to say "Okay, maybe you can make a regex that searches for newlines that aren't at the end of lines" but then I realized what I was saying.
05:59
< Reiv>
(data that is non-text is not in a string - flat numbers, etc)
06:00
<@Derakon>
What you could do is only eliminate newlines that are not immediately preceded by a comma
06:01
<@Derakon>
In vim, :%s/[^\(,\)]\n/\1/g
06:01
< Reiv>
That could work.
06:01
<@Derakon>
...no, wait, that's broken.
06:01
< Reiv>
Can I have them repaced by a space?
06:02
<@Derakon>
It's not properly preserving the preceding character.
06:02
<@Derakon>
Sure, you can replace the newline with anything you want.
06:02
< Reiv>
I want the unwanted newlines to turn into spaces.
06:02
<@Derakon>
Ah, there we go.
06:02
<@Derakon>
:%s/\([^,]\)\n/\1 /g
06:02
<@Derakon>
Had my parens in the wrong place.
06:03
< Reiv>
So how do I load files into vim?

Here's an explanation of the command, by the way: http://paste.ubuntu.com/165299/
06:05
<@Derakon>
I should note that it's entirely possible that you're dealing with Windows newlines here, in which case \n may not capture them. But it's worth trying.

Can you use SDL to load textures without setting a graphics mode?

<@TheWatcher>
SDL_Image's IMG_Load should work without setting a graphics mode, IIRC
16:42
<@gnolam>
Good.
16:43
<@gnolam>
Because SDfaiL apparently can't set a decent graphics mode to save its own life.
16:43

So we have to find another library to take its place. :P

Generally speaking, X will not let you set any graphics mode that it doesn't feel like letting you set.
17:50
<@gnolam>
I know. But it fails under Windows as well. :P
17:51
<@McMartin>
There's an option to force the shift, but I don't remember what it is offhand, and I don't know if it requires UAC/RaA
17:51
<@McMartin>
We ran into this for UQM too, and even there I think X just gave us a tiny little window surrounded by blackness
17:52
<@McMartin>
... let me see if it force-respects aspect ratio, since I remember VirtualBox tended to die horribly under those circumstances
17:53
<@McMartin>
... yup, UQM successfully set 320x240 on a 16:10 screen, while VBoxSDL crashes when set to fullscreen with a 4:3 monitor.
17:55
<@gnolam>
We're forced to use bloody /GLUT/ here.
17:55
<@gnolam>
Since SDL just plain fails at setting any usable mode.
17:55
<@McMartin>
Anyone who voluntarily uses GLUT deserves what they get~

Fuck you,

SDL_Video = SDL_SetVideoMode (ScreenWidthActual, ScreenHeightActual, 32, SDL_SWSURFACE | SDL_ANYFORMAT | SDL_FULLSCREEN);
17:56
<@gnolam>
Yeah. Now try that with OpenGL.
17:56
<@gnolam>
Under no OS does it give us a double buffered mode.
17:56
<@McMartin>
One moment while I consult the OpenGL version of that file.
17:57
<@gnolam>
Under Windows, /one/ of us gets a usable mode - one that doesn't tear itself apart.
17:57
<@McMartin>
Call SDL_GL_SetAttribute (SDL_GL_DOUBLEBUFFER, 1);
17:57
<@McMartin>
before SDL_SetVideoMode
17:58
<@gnolam>
Now why didn't I think of that? Oh wait, I did. It doesn't. Fucking. WORK.
17:58
<@McMartin>
You will also want to set SDL_GL_RED_SIZE, GREEN, and BLUE.
17:58
<@gnolam>
It creates a window, but refuses to update it.
17:58
<@gnolam>
SDL_Flip or no SDL_Flip.

18:00

SDL_GL_SwapBuffers().

Actually, Sable may be difficult to acquire at the moment since I think my homepage was taken down yesterday.

18:06 * TheWatcher notes that code theft isn't required, when, say, almost every NeHe tutorial past 6 has SDL versions that demonstrate double buffering
18:07

Copy something that works, tweak it towards your use case, testing after every change to make certain it still works.
18:08

That said, I again from UQM experience know for a fact that certain versions of SDL have buggy routines in their SIMD blitters. Shouldn't affect OpenGL, but.

19:28 * jerith ponders runtime switching of libraries in a test suite and the least horrible way of doing it.
19:30
<@jerith>
Here's the backstory: Said library is heavily dependent on a third-party web service. The unit tests currently make calls to said service.
19:30
<@jerith>
Well, the test version of said service.
19:31
<@jerith>
They're one of the few places nice enough tp provide a public sandbox.
19:31
<@jerith>
Which is about the best thing I can say about them, really.
19:32
<@jerith>
But anyway, this test service is sometimes broken which makes tests fail. Also, tests run at build time and the build machine should not have external deps.
19:32
<@jerith>
So, I want to stub out the library for the common case.
19:33
<@jerith>
But I still want to hit it when I'm testing by hand, to make sure that I haven't broken something that my stubs don't catch.
19:34
<@jerith>
However, given the amount of tests involved, I really don't want to have to write everything twice.
19:35
<@jerith>
So I want to somehow inject something into the system that will switch between stubs and live.
19:35
<@jerith>
My question: Am I utterly insane?
19:36
<@jerith>
Also, has anyone done this kind of thing and can perhaps provide warnings or advice?
