| 03:28 | < [R]> | I writting some code to automate D&D table lookups (for loot generation). The way it basically works is random number from 1-100, check against table. But the table could have some entries that come up on multiple values. I'm trying to figgure out what that cleanest way of coding that is. |
| 03:29 | <@Alek> | I recall seeing "case 1 do X case 5 do Y etc" where for example 1-4 would go to X. |
| 03:29 | <@Alek> | I forget the language. |
| 03:30 | <@Alek> | I also recall seeing in another language "case 1 case 2 case 3 case 4 do X case 5 etc do Y" |
| 03:30 | <@Alek> | each case statement being on a separate line, in both cases. |
| 03:30 | <~Vornicus> | That is too code and not data enough |
| 03:30 | <@Alek> | in the second case each case statement passing down until it reached the one with a do. |
| 03:30 | <@Alek> | yeah, sorry. |
| 03:31 | < [R]> | That works yeah, but it's pretty ugly. |
| 03:31 | <@Alek> | it probably depends on what language you're using. |
| 03:31 | <~Vornicus> | thing goes (low, high, entry). You iterate the table for the thing s.t. low <= x <= high and that gives you your entry. |
| 03:31 | < [R]> | It's not a hard task, I just don't want to have giant functions, or unreadable functions (as I have a bunch of tables I want to get through) |
| 03:32 | <~Vornicus> | ...this is a little messy because you basically have to tell it twice for each boundary |
| 03:32 | <@Alek> | I'd probably go "for X, if X <=10, Y; if X<=20, Z; etc" |
| 03:33 | <@Alek> | or elseif, anyway |
| 03:33 | <~Vornicus> | possibly: (width, entity); then you can go if x > width: x -= width; else: do_thin_with_entity |
| 03:33 | <@Alek> | nested elseifs. not very elegant, perhaps, but it should work. |
| 03:33 | <@Alek> | but yeah, you're looking for more elegance. |
| 03:34 | < [R]> | I could probably do something like: [[90, '3'], [60, '2'], [30, '1'], [0, '0']] for a table of: 0-29: 0; 30-59: 1, 60-89: 2, 90-100: 3. Code would just loop through until it rolled on or under the value. |
| 03:34 | <~Vornicus> | You can tune widths so they add up to exactly 1, or you can as a first shot iterate over the entire thing. |
| 03:34 | <~Vornicus> | and figure out the right scale for rand |

| 03:39 | <@Reiv> | Don't have to tell for each boundary |
| 03:39 | <@Reiv> | Hell, you can write a naieve one if you want |
| 03:40 | <@Reiv> | Data is a tuple: Top value, (ie, 1-5 is listed as '5') and your text as you see fit |
| 03:40 | <@Reiv> | check i = val; if no val, i++, loop |
| 03:41 | <@Reiv> | So if you roll a 3, it'll look for 3, then 4, then 5 |
| 03:41 | <@Reiv> | This is terrible code but it demonstrates how simple you can get |
| 03:41 | < [R]> | Aye, I decided on something like that, but I don't need to do the increments |
| 03:41 | <@Reiv> | Some small amount of work of 'find the smallest value that is greater or equal to the random number generated" is sufficient |
| 03:42 | <@Reiv> | Yeah, I was mostly making it explicit for ease of comprehension |
| 03:42 | <@Reiv> | (A bit like I might explain sorting with bubble sort for sheer simplicity, but it's still a terrible idea) |

| 10:51 | <~Vornicus> | ErikMesoy: the iphone 5 acts 320px wide. |
| 10:52 | <~Vornicus> | Typical modern site design takes into account varying screen sizes by rearranging objects according to browser width. Foundation and Bootstrap are popular; I prefer Foundation. |
| 10:52 | <~Vornicus> | are popular libraries for doing this, that is |
| 10:53 | <@gnolam> | I don't know which one decides that you're on mobile if width < height, but I want to strangle them with their own intestines. |
| 10:54 | | thalass_ [thalass@Nightstar-283.o7s.158.104.IP] has joined #code |
| 10:54 | <@TheWatcher> | ... yeah |
| 10:54 | <~Vornicus> | Neither of those |
| 10:54 | <@TheWatcher> | Anyone doing that should have their figgin roasted on a spike. |
| 10:54 | <~Vornicus> | You can of course rearrange accordingly - landscape and portrait mode are available to media queries |
| 10:55 | <~Vornicus> | But generally you should avoid that unless what you *really* want is for everything to fit above the fold. |
| 11:10 | <@TheWatcher> | I don't remeber running into Foundation before... that looks like it could be useful, thanks Vorn. |
| 11:20 | <~Vornicus> | it's good stuff. If you already run a sass rig it's supposedly even better but I don't have the arsage to do that |

| 11:31 | | * Vornicus hatadroids catadroid. |
| 11:31 | < catadroid> | Things I have done this week: nearly doubled the performance of our vector::push_back. Fixed a memory smashing bug in vector::insert when users were inserting aliased items |
| 11:31 | < catadroid> | I think I'm alright to think of myself as somewhat of an expert |
| 11:32 | | * Vornicus gives catadroid a pointy purple hat with silver stars and moons on it. |
| 11:32 | <~Vornicus> | I'm kind of surprised there's this kind of performance to be gleaned, really |
| 11:34 | <@TheWatcher> | catadroid: nice! |
| 11:37 | | * TheWatcher eyes foundation some more, sighs vaguely at jquery |
| 11:38 | <~Vornicus> | don't need it for layout; only for things that say js on there. |
| 11:39 | | * TheWatcher nod |

| 11:42 | <@TheWatcher> | (jquery is one of those frameworks I know and can use fine, but don't actually /like/; mootools' approach works so much better in my head, and I think makes for much cleaner code, but apparently I'm in a tiny minority so :/) |
| 11:45 | <~Vornicus> | Yeah, jq has a huger install base, I've never actually seen mootools live |
| 11:45 | <~Vornicus> | which kinda makes mootools hard to get into |

| 11:56 | < catadroid> | Yeah, I was surprised as well |
| 11:56 | < catadroid> | But it was following a generic insert path, which is an inherently slower operation |
| 11:59 | < catadroid> | (I was actually exaggerating slightly - it's more like 30% in the general case x)) |
| 11:59 | < catadroid> | But still |
| 11:59 | <@TheWatcher> | 30% is still significant |
