01:36 Copenhagen_Bram I wonder... how would a p2p minetest server work?
01:42 Calinou         it wouldn't? :P
01:42 Calinou         there would be little benefit compared to the downsides
01:42 Calinou         (let alone the sheer amount of work required)
01:42 Calinou         the fact the world is persistent makes that difficult in the first place
01:42 Calinou         (think of a torrent, if nobody seeds it, you can't get the file at all)
01:51 Wuzzy           what about a p2p server list?

02:52 Sketch2         hmm, yea forum replies  502 Bad Gateway nginx/1.12.2
02:52 scr267_         Oh hum, yep FYI 502 NGINX errors
02:52 scr267_         LOL, yeah just saw that too
02:52 scr267_         Well that confirms it for me, thanks Sketch2

20:02 MaybeItsMia     Is it possible to "append" statements to an already existing function in Lua?
20:02 rubenwardy      yes, define a new function which wraps it
20:03 rubenwardy      local old = func;   func = function()   old();    stuff   end
20:03 MaybeItsMia     Would I get the new functionality by calling the old function?
20:04 rubenwardy      err
20:05 rubenwardy      if you called func() you would
20:05 rubenwardy      however, the old function still exists the variable has just been redefined
20:07 MaybeItsMia     Wait so is the function acting like a variable?
20:07 rubenwardy      yes, functions are first class in lua meaning that they are stored in variables
20:09 rubenwardy      well, first class actually just means that functions are values like any other value
20:12 MaybeItsMia     ugh, tbh what I'm thinking about might not be the best way to do what I want. I'm working on a mod to play background music like MC, playing a random track at sunrise, sunset, and whatnot. I do have a mod that works using "register_globalstep" to check every second if it's a particular time of day, but it would be nicer to have a system where I
20:12 MaybeItsMia     could define "triggers " to easily just run a function at points in the day that I determine
20:14 rubenwardy      sounds like you want the observer pattern

20:14 MaybeItsMia     oh thanks!
20:14 Krock           !book pattern
20:14 MinetestBot     Krock: Nothing found.
20:15 MaybeItsMia     I basically know how to code, I'm not super familiar with actual best practices, or designing code, ha ha
20:16 sfan5           well it's not like you can use this pattern without anyone giving you the event you need
20:16 sfan5           and afaik there is no way to specifically listen to changes to in-game time
20:16 rubenwardy      it sounds like they are the author of the mod which checks the time of day
20:17 MaybeItsMia     I mean register globastep works, I'm just concerned about how computationally intensive it might be. Also It's not super extensible
20:31 MaybeItsMia     Is there more examples of the observer pattern? I'm having my trouble wrapping my head around it?
20:34 rubenwardy      every where in the Lua API
20:34 rubenwardy      register_globalstep is an example of the observer pattern
20:35 MaybeItsMia     Implementation I mean
20:35 rubenwardy      it's a fancy term for callbacks where the thing making the callback doesn't care who is listening
20:35 rubenwardy      the book already contains an example
20:36 MaybeItsMia     So I want to get to the point where I can say:
20:38 Sketch2         you could make it so it doens't check time absolutely ever clock-tick.  just have it do it when someone speaks, or joins / parts the server
20:38 MaybeItsMia     mymobs.register_on_timeofday()    do stuffend)
20:39 MaybeItsMia     Sketch2 I already have it running every second instead of every tick
20:39 Sketch2         ok, but my point was that you were worried about it being computationally expensive.
20:40 Sketch2         the time change you're looking for is measured in hours, not seconds
20:40 Sketch2         so you can cut back on the number of checks
20:40 Sketch2         this will save you vast amounts of processing power
20:43 MaybeItsMia     I'm weirdly anal about the music starting at exactly sunset.... though I guess I could have it check every minute or so, then if it's within a minute of sunset I could have it que the music to play in the remaining time till the point I want to play it, though that might be a bit hacky, and lead to weirdness if people skip around time.
20:43 MaybeItsMia     *sunrise, though it doesn't make much of a difference to my point
20:44 MaybeItsMia     weirdly in minetest sunrise does not take place at exactly .25, but actually a bit before that
20:58 Krock           there's some value specified in the code that defines the sunrise
21:48 AlexYst         What does the v7 caverns flag do? I thought it was responsible for the larger caves, but when I turn caves off and caverns on, I get a completely-solid earth, with no air pockets in the ground.
