Okay, quick question for someone who works with MySQL a lot: With an application like a query browser that will make a lot of transactions with a database, is it better to open the connection and close it when the application is closed, or open and close it every time a query is performed?
00:08
<@Vornicus>
Generally the former, unless you're getting close to the connection limit.

Well, it's more that I'm turning Niobium - a fully-general 2D game engine - into a more specific program. So a great deal of code is no longer needed.

Tasm? What for?
02:18
< Doctor_Nick>
IDA does not have a dos debugger

I need Turbo Debugger and turbo debugger comes with TASM
02:19
<@ToxicFrog>
...I think it does.
02:19

I know it has a DOS disassembler, and ISTR using the debugging features as well when working on ss1hr.

can you point me to a version that does, then?
02:20
< Doctor_Nick>
because I haven't found it in the past 4 days
02:20

< Derakon>
Any thoughts on reading the contents of a directory from within C++?
03:51
< Derakon>
Or within Lua, for that matter.
03:52
<@ToxicFrog>
Lua does not have it in the stdlib, but it's easy to bind if you're in POSIX.
03:52
<@ToxicFrog>
If you're in windows it's somewhat less easy to bind and wholly nonportable but still doable.
03:53
<@ToxicFrog>
From inside C++, again, if you're on POSIX, the functions you want are opendir, readdir, and closedir.
03:53
< Derakon>
Bahh...I'm trying to avoid OS-specific code.
03:53
<@ToxicFrog>
There is no wholly cross-platform way of doing this.
03:53
< Derakon>
I find that mildly surprising, but oh well.
03:53
< Derakon>
opendir, readdir, and closedir, huh?
03:53
<@ToxicFrog>
Basically, opendir, readdir, and closedir, or possibly ftw depending on what you want to do, will do it on BSD, OSX and Linux at least.
03:53
<@ToxicFrog>
(ftw is totally awesome; look it up)
03:54 * Derakon snerks.
03:54
< Derakon>
You realize the normal expansion of that, don't you?
03:54
<@ToxicFrog>
On windows, it's something like FindFirstFileEX, FindNextFile, and FindClose.
03:54
<@ToxicFrog>
Which, of course, is wholly signature and semantics incompatible with any of the POSIX functions mentioned above.
03:54
<@ToxicFrog>
And yes, I do, which is why I write that as 4tw.
03:55
<@ToxicFrog>
Because ftw is and forever will be File Tree Walk.
03:55
< Derakon>
Well, my use case here is that I want to load a bunch of Lua files from a known directory. So I just need the filenames.
03:55
<@ToxicFrog>
(you give it a path and a function. It calls the function on every file and directory under path, and recursively calls itself on every subdir)
03:55
< Derakon>
Or hell, if Lua supports "load all Lua files in this directory", that'd work too.
03:56
< Derakon>
That sounds handy for compartmentalizing my plugins...
03:56
<@ToxicFrog>
Tragically, it does not. I got around this with a bash script that generated a .loader.lua file in each dir that loaded everything in it and the .loaders for all its subdirs.
03:56
<@ToxicFrog>
It would, however, not be hard to bind ftw to Lua.
03:57
< Derakon>
I'm working on bootstrap logic right now, so it's all in C++.
03:57
<@ToxicFrog>
Indeed I can probably do it in under half a hour, counting the time taken to bind the struct stat.
03:57
<@ToxicFrog>
In that case you can use ftw directly.
03:57
< Derakon>
Right.
03:57
<@ToxicFrog>
I think mingw has an implementation.
03:57
< Doctor_Nick>
*sob*
03:57
< Derakon>
I'm on a Mac. *shrug*
03:57
<@ToxicFrog>
If not, I actually have a windows implemention of ftw kicking around which you can use for the windows release.
03:57
< Derakon>
Ooh, nice.
03:57
< Derakon>
Now, uh, what library is it in? ¬.¬
03:58
<@ToxicFrog>
(which I wrote for some SGOS-related stuff, but they won't mind if you use it)
03:58
<@ToxicFrog>
...what do you mean, what library?
03:58
<@ToxicFrog>
What includes/links do you need?
03:58
< Derakon>
I can't just invoke ftw without including its library file first.
03:58
< Derakon>
Yes.
03:58
< Derakon>
s/library/header.
03:58
<@ToxicFrog>
<ftw.h>
03:58
<@ToxicFrog>
And it's in libc, no special links are needed.
03:58
< Derakon>
That would make sense.
03:58
< Derakon>
Oh, really.
03:58
<@ToxicFrog>
This is mentioned in the man page.
03:59
< Derakon>
Normally I wouldn't think that the C++ headers would do that. They tend to be as minimal as possible.
03:59
< Derakon>
E.g. "we can't put print into the standard library! What if someone's writing an elevator controller?"
04:00
<@ToxicFrog>
..
04:00
<@ToxicFrog>
You've read sections 2 and 3 of the Manual, right?
04:00
<@ToxicFrog>
libc is huge.
04:00
<@ToxicFrog>
libstdc++ is huger.
04:00
< Derakon>
I, um, think I read them. Years ago.
04:01
<@ToxicFrog>
Ok, actually, libstdc++ is smaller than I thought.
04:01
<@ToxicFrog>
It's around 2.6MB.
04:01
<@ToxicFrog>
libc is 4MB.
04:02
< Derakon>
Fun times.
04:02
<@ToxicFrog>
This is still absurdly huge compared to Lua, but in fairness it does a hell of a lot more stuff.
04:04
< Derakon>
...can something in a directory be simultaneously a file and a directory?
04:04
< Derakon>
Or can I assume that "if (!(flags & FTW_F)) return;" will limit me to just files?
04:06
<@ToxicFrog>
Correct.
04:06
< Derakon>
Okay, good.
04:06
<@ToxicFrog>
You can also look at the stat structure for more detail.
04:19
< Derakon>
error: argument of type 'int* (World::)(const char*, const stat*, int)' does not match 'int (*)(const char*, const stat*, int)'
04:19
< Derakon>
So what exactly does it mean for the asterisk to be in parentheses, then?
04:19
< Derakon>
Or did I need to make it static...?
04:21
<@ToxicFrog>
I think that just means "I cannot be arsed to be put a name here, because it's a function pointer"
04:21
<@ToxicFrog>
You're passing a method in, yes?
04:21
<@ToxicFrog>
Is it static?
04:21
< Derakon>
It wasn't.
04:21
<@ToxicFrog>
It has to be.
04:21
< Derakon>
And now I forgot the depth field.
04:22
< Derakon>
Yeah, I figured that out when I said "Or did I need to make it static...?".
04:22
<@ToxicFrog>
Using non-static member functions as function pointers requires all kinds of wackiness to make sure that this is non-null.
04:22
< Derakon>
Because of course it won't have a handle on the class that the function is declared in.
04:24
<@ToxicFrog>
Yep.

< Derakon>
Man, manipulating strings in C++ sucks. ¬.¬
04:29
<@ToxicFrog>
You noticed.
04:30
<@ToxicFrog>
I have actually come to the conclusion that for any reasonable string manipulation, it is easier to call out to Lua~
04:30
<@ToxicFrog>
Indeed, even when writing in C, I tend to (ab)use Lua as a general-purpose hashing and string manipulation library.
04:30
< Derakon>
Heh.
04:33
< Doctor_Nick>
Derakon: I had to make my own string class in C++
04:33
< Doctor_Nick>
THAT sucked
04:33
< Derakon>
Heh. One of the more infamous programming assignments I had in college was called "chunky strings".
04:33
< Derakon>
Basically it required you to write a string library that represented strings in "chunks", to make modifications cleaner.
04:34
< Derakon>
So you had a linked list of variably-sized strings (where each element of the list had a fixed maximum size, and expansion required creating new chunks).
04:34
< Doctor_Nick>
linked lists was my next project
04:35
< Doctor_Nick>
it only took me an hour and a half to track down all the segfaults, which was a miracle in itself
04:35
< Derakon>
Heh.
04:36
< Derakon>
Okay, what the hell is the convert-string-to-uppercase function called in C++? >.<
04:36
< Doctor_Nick>
i forget
04:36
< Derakon>
Oh, they'll see it in a bit.
04:36
< Derakon>
Er, wrong channel.
04:36
< Doctor_Nick>
i think if you just do toupper(string) it'll do an automatic type conversion
04:37
< Derakon>
world.cpp:161: error: no matching function for call to 'toupper(std::string&)'
04:37
< Derakon>
 /usr/include/ctype.h:130: note: candidates are: int toupper(int)
04:37
< Doctor_Nick>
whoops
04:39
< Doctor_Nick>
here's one way to do it: http://www.gammon.com.au/forum/bbshowpost.php?bbsubject_id=2896
04:40
< Derakon>
That's ridiculous.
04:40
< Doctor_Nick>
you could also do a for loop
04:41
< Derakon>
Also absurd.
04:41
< Derakon>
There should be a built-in function to handle that kind of extremely basic string manipulation.
04:41
< Derakon>
But for the moment, I will simply require filenames to end in ".lua", case-sensitive.
04:42
< MyCatVerbs>
Derakon: it's fucking C, for chrissake?
04:42
< Derakon>
Even then.
04:42
< Derakon>
Also, C++.
04:43
< MyCatVerbs>
Derakon: what in the nine Hells made you assume that anything useful would be included?
04:43
< Derakon>
In a library!
04:44
< MyCatVerbs>
{int i=0; int x = strlen(y); for (int i=0;i<x;i++) { if(isAlpha(y)) y = toUpper(y); } } // done
04:44
< MyCatVerbs>
Erk, plz kill off the redefinition of i in that. Anyway. Done.
04:44
< Derakon>
Heh.
04:44
< Doctor_Nick>
doesnt toUpper automatically check if it's an alpha?
04:51
< MyCatVerbs>
Doctor_Nick: yes. But if you knew that, WHY DIDN'T YOU JUST WRITE THE -ONE LINE- FOR LOOP YOURSELF?
04:51
< Doctor_Nick>

04:53
< MyCatVerbs>

04:54
< Derakon>
The last.
04:55
< MyCatVerbs>
Oh, what're you writing and what're you targeting?
04:55
< Derakon>
Also, a great deal of my code was already written, in C++, by me. I don't want to reimplement it.
04:55
<@ToxicFrog>
Derakon: concerning tolower:
04:55
< Derakon>
I'm doing my own take on the Escape Velocity series, and I'm targetting as many computers as I can.
04:55
<@ToxicFrog>
There's no function to convert an entire string to lowercase.
04:56
<@ToxicFrog>
However, there is strncasecmp.
04:56
< Derakon>
...that works. ¬.¬
