09:54:24 * Keymaker thinks about writing a brainfuck program that prints out its own amount of instructions as integer
10:14:41 <Keymaker> this isn't what i originally had in mind, but it looks nice :)
10:14:42 <Keymaker> ++-++-++-++-++[>++++++++<-]>+++..
10:24:11 <Keymaker> here is a bit shorter version, that looks better

12:49:03 <Keymaker> what is wrong with this python code?
12:49:05 <Keymaker> m = [1, 2, 3, 0]
12:49:05 <Keymaker> while m[i] > 0:
12:49:05 <Keymaker> print m[i]
12:49:49 <kipple> don't you need to increment i?
12:49:58 <Keymaker> yes,
12:50:02 <Keymaker> but that whole thing doesn't work
12:50:27 * kipple doesn't know python :(
12:50:33 <Keymaker> :(
12:50:44 <Keymaker> i'm not very familiar with this either, as you can see ;)
12:50:49 <int-e> lemme think
12:51:19 <int-e> NameError: name 'i' is not defined
12:51:25 <int-e> that's quite a clue, isn't it?
12:51:41 <Keymaker> no
12:51:44 <int-e> add a i = 0 before the loop and it's an infinite loop
12:52:04 <int-e> i = 0
12:52:04 <int-e> m = [1, 2, 3, 0]
12:52:04 <int-e> while m[i] > 0:
12:52:04 <int-e>    print m[i]
12:52:04 <int-e>    i += 1
12:52:07 <Keymaker> hmm
12:52:09 <Keymaker> fun
12:52:14 <Keymaker> i thought i tried it already :)
12:52:25 <Keymaker> thanks
12:52:43 <Keymaker> i thought python didn't need variable defining
12:53:25 <int-e> hmm, that's not quite true. (obviously)
12:53:39 <int-e> but you don't need to declare the variable before assigning a value to it
12:53:44 <Keymaker> ah
12:53:48 <int-e> for a in m:
12:53:48 <int-e>    print a
12:53:58 <int-e> (that's slightly different though, it prints the 0, too)
12:54:08 <int-e> (and goes past the 0 if the list is longer)
12:57:17 <int-e> for a in m:
12:57:17 <int-e>    if a == 0:
12:57:17 <int-e>       break
12:57:17 <int-e>    print a
12:57:36 <int-e> (ok. that's the obvious alternative if you don't need the index later - I'll stop now)
12:57:44 <Keymaker> :)
13:07:31 <Keymaker> i hate normal languages.. grhh
13:08:17 <int-e> Hmm. I think Python is very neat.
13:44:13 <Keymaker> done; http://koti.mbnet.fi/yiap/stuff/selfmd5.py
13:45:03 <kipple> neat
13:45:32 <Keymaker> it's md5 (and output) is (or at least should be) b1f532d69db9c1366389ff855da9ae04
13:47:50 <int-e> ", ".join(map(str, [45,45,45])) -> "45, 45, 45"
13:48:07 <int-e> you might like this :)
13:48:47 <int-e> (it works on arbitrary lists, of course)
13:48:57 <int-e> of numbers.
13:49:18 <int-e> hmm. actually strings don't hurt either
13:49:35 <int-e> (but Python prefers to print them with '')
13:49:43 <Keymaker> i can't get it working
13:49:48 <Keymaker> perhaps my python version is too old
13:50:13 <int-e> hmm.

13:50:44 <int-e> how old is 'old'?
13:50:55 <Keymaker> could be few years

13:51:06 <Keymaker> hi
13:51:08 <int-e> I have 2.4.2 - which is fairly modern.
13:51:28 <int-e> it works in 2.3 too
13:52:29 <Keymaker> 2.3.3 is says
13:53:01 <Keymaker> hmm, do i need to have anything else in the file than that code line?
13:53:11 <int-e> did you strip off the ' -> [...]' part?
13:53:17 <Keymaker> nope
13:53:22 <int-e> you should, sorry
13:53:29 <Keymaker> oh, ok
13:53:42 <Keymaker> the interpreter was complaining about "->" part
13:54:07 <int-e> I just used it to show the result on the same line.
13:54:23 <Keymaker> ok
13:54:53 <Keymaker> useful line of code
13:56:16 <Keymaker> consider nothing obvious when talking to me about something ;)
13:56:44 * jix is working on a emulator...
13:56:46 <jix> +n
13:56:50 <Keymaker> what kind of?
13:56:55 <jix> colecovision
13:57:00 <Keymaker> what's that?
13:57:09 <jix> some z80 game-device
13:57:19 <Keymaker> ah
13:57:23 <jix> using sound and graphic chips from TI
13:58:09 <Keymaker> nice :)
13:58:17 <Keymaker> how do you know how it works?
13:58:58 <jix> there are internet sites that describe the hardware
13:59:06 <Keymaker> ah
13:59:34 <jix> and i know how the z80 works by viewing offical and inoffical z80 documentation
13:59:55 <Keymaker> ok
14:03:05 <int-e> s = ['print s', 'print "\\n".join(s)']
14:03:05 <int-e> print "s = ", s
14:03:05 <int-e> print "\n".join(s)
14:03:10 <int-e> python quine :)
14:03:21 <Keymaker> nice :)
14:03:22 <int-e> hmm, one space too much.
14:03:31 <int-e> should be print "s =", s
14:03:36 <Keymaker> ok
14:03:52 <int-e> s = ['print "s =", s', 'print "\\n".join(s)']
14:03:52 <int-e> print "s =", s
14:03:52 <int-e> print "\n".join(s)
14:03:58 <int-e> that's better
14:04:19 <int-e> (the fun thing is that python quotes strings inside lists when printing lists)
14:06:12 <int-e> you can exploit the same thing with the str() function
14:06:22 <int-e> so it can be used for the md5sum program as well
14:07:13 <jix> ruby port:
14:07:14 <jix> s = ["puts 's = '+s.inspect","puts s"]
14:07:14 <jix> puts 's = '+s.inspect
14:07:14 <jix> puts s

21:25:56 <Keymaker> bf-hacks.org has been updated with a new program i made up today!
21:25:58 <Keymaker> http://bf-hacks.org/hacks/ptmbsg.b
21:26:21 <Keymaker> it's a Prouhet-Thue-Morse binary sequence generator
21:26:39 <Keymaker> i think it's one of my best programs. check it out :)
21:39:15 <jix> one of my best programs (sort) not the shortest sort but very short: >>,[[-[->>+<<]+>>]<+<[-<<]>>,]+[>[-<.>]<[->>+<<]>>+]
21:39:27 <Keymaker> what it does?
21:39:35 <jix> it sorts all input bytes
21:39:41 <Keymaker> ah
21:39:43 <Keymaker> cool
21:40:17 <jix> uses 0 for eof...
21:40:45 <Keymaker> ok
21:41:25 <Keymaker> that kind of thing has once been in bf golf if i remember correct. if you had been around at that time you would've placed well
21:41:34 <Keymaker> (i wasn't around at that time, btw)
21:42:14 <jix> the version at short.b (where the shortest hw is in) is 1 or 2 bytes shorter than mine
21:42:38 <Keymaker> so, that's pretty good solution ;)
