| 01:43 | < simon`_> | hmm... |
| 01:45 | < simon`_> | I've always used the compiler tools for Moscow ML rather than those for SML/NJ, and that's my fault. so before I really give this idea any thought, I should look at their tools. but here it is anyway: MosML's lexer tools suck. its Lexing library is inadequate, and its lexbuf state is hard to tinker with when exploring how a lexer generator works during a course. SML/NJ's might be slightly complicated, though. |

| 08:52 | <~Vornicus> | Arg. The 12 Weights puzzle is full of confusion. |
| 09:02 | <~Vornicus> | Okay. putting 1,2,3,4 on one side and 5,6,7,8 on the other, I see that the 1,2,3,4 side is lighter. This gives 8 cases: 1L 2L 3L 4L 5H 6H 7H 8H. I now need to make a setup which will have each of the three outcomes appear in no more than three cases. |
| 09:08 | | * Azash ponders for a moment |
| 09:09 | <@Azash> | What if you take that to find the abnormal set of four |
| 09:09 | <@Azash> | Then choose an arbitrary pair from that set and weigh it against two known-to-be-regular weights |
| 09:09 | <@Azash> | This will narrow down which is the abnormal pair in your abnormal four |
| 09:10 | <@Azash> | Then pick one of the two at random and weigh against a known-regular weight |
| 09:10 | <~Vornicus> | Only get three weighings. |
| 09:11 | <@Azash> | What I just proposed has three weighings |
| 09:11 | <@Azash> | Wait, you need to find out if it's lighter or heavier? Nevermind |
| 09:12 | <~Vornicus> | I got it. |
| 09:13 | <~Vornicus> | well no, I have to find out which one it is. |
| 09:13 | <~Vornicus> | But the thing is: Yours just required four weighings, because you forgot to count the one I already did. |
| 09:15 | <@Azash> | No it didn't |
| 09:15 | <@Azash> | Your is the first step in mine |

| 09:18 | | * Azash rolls out |
| 09:18 | <~Vornicus> | Thing is that is 1234 and 5678 are unequal then you don't know which of those two sets are abnormal. |

| 09:20 | <~Vornicus> | Second weighing was 1 2 5 6 vs 3 7 9 10; this way 1L 2L and 7H will show right heavy, 3L 5H 6H will show left heavy, and 4L and 8H will show equal. |
| 09:20 | <~Vornicus> | And then those three you can handle by putting an L and an H on one side and 9 10 on the other. |
| 09:21 | <~Vornicus> | And now, having solved 12 Weights on my own, I can sleep victorious. |

| 17:52 | | mac [mac@Nightstar-fe8a1f12.il.comcast.net] has joined #code |
| 17:54 | < mac> | hey does anyone know if its possible to accept 2 arguments and 3 arguments from a function? or to have a function check for how many arguments there are and send the correct inputs to the correct function? |
| 17:54 | <@rms> | language? |
| 17:56 | < mac> | php or javascript |
| 17:56 | < mac> | maybe even java |
| 17:56 | < ErikMesoy> | IIRC, Java requires different functions for different numbers of arguments. |
| 17:57 | <@rms> | js has an arguments variable, use it as an array |
| 17:57 | < mac> | so say I am sending? White_red;#FFFFFF;#FF0000 |
| 17:57 | < ErikMesoy> | foo(x, y) and foo(x, y, z) will automatically match calls with the right number of functions to the function definitions with that many arguments. |
| 17:57 | < mac> | where ; is the separator for arguments. |
| 17:57 | <@rms> | PHP has functions to do the same |
| 17:57 | < mac> | oh neat |
| 17:58 | <@rms> | java has overloading |
| 17:59 | < mac> | because i might want to send White_red;#FFFFFF;#FF0000 or just White;#FFFFFF but i want my program to be able to discern bailed on the number of arguments passed. |
| 18:00 | < ErikMesoy> | In Java, I'd overload the function name by writing a two-argument function and a three-argument function. Not sure about the others. |
| 18:00 | <@rms> | PHP has argument defaulting IIRC |
| 18:19 | <@Azash> | 18:56 < ErikMesoy> IIRC, Java requires different functions for different numbers of arguments. |
| 18:19 | <@Azash> | Also type-specific |
| 18:20 | < ErikMesoy> | Yeah. JavaFunction(int i, string s) and JavaFunction(int i, int j) will happily live alongside each other, and calls will be sent to the appropriate one. |
| 18:21 | | * Azash ponders what will happen if you have Foo(String) and Foo(Integer) and call Foo(null) |
| 18:23 | < ErikMesoy> | Today is a good day to test it. :) |
| 18:35 | < mac> | oh let me know what happens if you try it |
| 18:35 | < ErikMesoy> | The world ends. |
| 18:37 | < ErikMesoy> | ooh, Python's str.partition() is neat. It lets me keep data in files as "Name: Description" and then partition(": ") to get out name and description easily. |
| 18:39 | < Syk> | owo |
| 18:39 | < Syk> | what if your description contains : in it |
| 18:40 | <@Tamber> | I would presume that you can split on only the first match in a line |
| 18:41 | <@Tarinaky> | ErikMesoy: I would suggest looking up json >.> |
| 18:42 | <@Azash> | Java approach: str = str.split("[^\\\\]: "); |
| 18:44 | <@Rhamphoryncus> | Syk: then you need a less daft file format ;) |
| 18:45 | <@Rhamphoryncus> | Well, if it's in the description and not the name it'd still work. Python's str.partition() only does a single match |
| 18:46 | < Syk> | ah |
| 18:46 | < Syk> | well that's good then |
| 18:46 | < ErikMesoy> | Rhamphoryncus: or a less daft naming convention |
| 18:47 | | * ErikMesoy will have to avoid putting colons in his names now. This is hardly a great loss. |
| 18:47 | <@Rhamphoryncus> | Just make sure you'll never want a newline in a description :) |

| 21:23 | < ErikMesoy> | I suspect there may be a cat on Moltare's keyboard |
| 21:31 | <@Alek> | nah, keyboard+head |
| 21:32 | < ErikMesoy> | Maybe it's Perl? |
| 21:36 | < ErikMesoy> | Hmm. Game dialogue. I would like for the player to talk to NPCs about something repeatedly without having to end and restart conversation, so the conversation should be able to loop, sort of. This means that a conversation branch should /not/ be implemented as a function which calls the next one depending on answer choice. |
| 21:36 | < ErikMesoy> | That could lead to being arbitrarily deep inside a function stack, which is bad. |
| 21:39 | < ErikMesoy> | So. Hm. A conversation branch returns a dict matching player responses to conversation branch IDs. So call the NPC's converse(branchID) function, print text, get back dict. A while(choice != exit) loop around this repeatedly presents the dict to the player, gets a responds, calls the NPC. What can go wrong with this? |
| 21:41 | <@Alek> | add a counter for each choice. if they keep asking about the same thing constantly, get the NPC mad. or maybe they'll get scared, break down, and change their story. |
| 21:42 | <@Alek> | personalities = good. |
| 21:42 | < ErikMesoy> | That is a bell. :p |
| 21:42 | < ErikMesoy> | Now is not the time to add bells and whistles. |
| 21:42 | <@Alek> | lol |
| 22:03 | < ErikMesoy> | Okay, now I'm hitting serious confusion and I request the channel's help rather than just an ear for rants and monologues: Something with variable reference/declaration in Python seems inconsistent and magic. http://pastie.org/5563184 |
| 22:06 | < ErikMesoy> | If I don't initialize a variable, a function with a conditional on the variable refuses to run. But after I initialize it, something in the function can still throw an error that the variable isn't initialized! |
| 22:10 | <@celticminstrel> | global done_before |
| 22:10 | <@celticminstrel> | On first line of function. |
| 22:10 | <@celticminstrel> | Should fix it, I think. |
| 22:10 | <@celticminstrel> | I guess the existence of an assignment forces it to be a local instead of a global variable or something? |
| 22:11 | <@celticminstrel> | I thought that was only if the assignment preceded a read-reference, but maybe not... |
| 22:11 | < ErikMesoy> | That needs to be a global? Why isn't it "global enough" for the function to see it? |
| 22:12 | <@celticminstrel> | I dunno? |
| 22:13 | < ErikMesoy> | Well, various attempts at globalization did not fix it. "global done_before" line at start by itself did not work. So I tried adding "global" in front of other references to done_before and none of them worked either. |
| 22:15 | < ErikMesoy> | Aha. I add to add a line reading "global done_before" both at the start of the file and in the start of the function. |
| 22:15 | <@celticminstrel> | ...that's odd? |
| 22:16 | < ErikMesoy> | Lesson learned: Python really doesn't want me to use globals. (I had seen earlier that you can't assign a global at the same time as you declare it. But now I see that I can't use it inside a function without telling the function about the globalness, too!) |
| 22:22 | < ErikMesoy> | Hmm, this sounds like I will end up using "global" as mild boilerplate for each zone that I want to have introduction text on. Hopefully I will see a non-boilerplate method of doing this tomorrow. |
