01:13 Sokomine     hi
01:27 VanessaE     thanks Teckla  :)

02:49 technomancy  what does it mean when minetest.env:get_meta returns nil?
02:50 technomancy  I would assume that only happens when the pos is invalid, but in this case the pos refers to an existing node where I've placed metadata before restarting the server
03:20 Sokomine     technomancy: the mapblock you're trying to get data from may not be loaded
04:11 RealBadAngel or meta is not set rather
04:39 technomancy  the block is definitely loaded; I'm standing next to the node.
04:40 technomancy  RealBadAngel: so that means the metadata k/v object is created on demand when it's set then?
04:47 RealBadAngel technomancy, let me check the sources, hold on
04:51 technomancy  on-demand on read or write would make for a more convenient API
04:53 RealBadAngel https://github.com/minetest/minetest/blob/master/src/script/lua_api/l_nodemeta.h#L32
04:54 technomancy  "However, it is NOT guaranteed that the method will return a pointer" ._.
04:54 RealBadAngel yes, thats why you should add the check for NIL
04:54 RealBadAngel and skip if you got it
04:55 technomancy  aka "watch out; it has bugs"?
04:55 RealBadAngel not really
04:55 RealBadAngel such not guaranteed situations happens usually on load
04:56 technomancy  "watch out, it has undesirable/unpredictable behaviour" then
04:57 RealBadAngel it happens all the time
04:57 RealBadAngel and i wouldnt call that bug
04:57 technomancy  just a source of bugs =)
04:57 RealBadAngel hehe yeah
04:58 RealBadAngel when something is not yet set, you shouldnt read it
04:58 RealBadAngel but how could you know that
04:58 RealBadAngel solution is to put check for nil as the first condition
04:58 technomancy  I would expect it to give nils when you call get_string, not when you call get_meta is all
04:59 RealBadAngel nil you are getting in lua when something is not set, not yet used
05:00 RealBadAngel so same code can fail on startup and after some time it may work
05:00 RealBadAngel meanwhile the data was simply set
05:01 RealBadAngel checkin for nil will let you survive the startup
05:02 RealBadAngel also dont forget that many things are done in threads

05:19 Calinou      "Atom now opens files larger than 2MB with syntax highlighting, soft wrap, and folds disabled. We'll work on raising the limits with these features enabled moving forward"
05:19 Calinou      :D
05:23 RealBadAngel bombastic
05:23 RealBadAngel soon your fridge will be able to even print that file
05:32 technomancy  RealBadAngel: Thanks for the explanation. I think I found a better way for this that doesn't involve metadata.
05:32 RealBadAngel what way?
05:33 RealBadAngel imho metadata is very flexible, since it can store anything
05:33 technomancy  well I already have to serialize off some tables to disk on save/load, so I just added this to that file
05:33 technomancy  metadata is good for strings and ints, but I was trying to put tables in it, which is a lousy fit
05:34 RealBadAngel well, you should just ask
05:34 RealBadAngel technic has many examples of your problem solved
05:34 RealBadAngel almost all technic tools store data in meta
05:34 technomancy  I realized about halfway through that a separate file would be better, but I was still curious about metadata because I'm sure I'll use more of it in the future
05:35 RealBadAngel lemme point you something
05:35 technomancy  RealBadAngel: I was using it for an environment table for shell sessions on my in-game server nodes.
05:35 RealBadAngel this is the way to store data in files: https://github.com/minetest-technic/datastorage
05:35 RealBadAngel per player
05:36 technomancy  keeping the environment table in sync with the serialized tables in node metadata would have been a mess
05:36 technomancy  theoretically possible using metatables, but metatables break iterators in lua 5.1 =(
05:38 technomancy  but this could be useful for some other things; thanks for the pointer
05:38 RealBadAngel https://github.com/minetest-technic/technic/blob/master/technic/tools/mining_drill.lua#L262
05:38 RealBadAngel see here, im treating here meta as a table
05:39 RealBadAngel not as a string
05:40 technomancy  yes but in this case the writes all come from a single place, so it's a good fit
05:41 RealBadAngel ofc
05:41 RealBadAngel best solution would be direct access for mods to db end
05:41 RealBadAngel and thats i will definitely code one day
05:41 RealBadAngel btw, fm already has it
05:42 technomancy  awesome
05:42 technomancy  especially if it can work with tables of arbitrary depth
05:43 RealBadAngel http://wiki.mudlet.org/w/Manual:Lua_Functions#Database_Functions
05:43 RealBadAngel we need that ported
05:44 technomancy  ported?
05:44 technomancy  or exposed to the sandbox?
05:45 RealBadAngel i mean luasql
05:46 RealBadAngel so you can directly throw tables into db and read them
05:46 RealBadAngel see the examples
05:47 technomancy  oh yeah, I guess tables of arbitrary depth won't work in sqlite
05:47 RealBadAngel its transparent
05:47 RealBadAngel whatever works in lua can be stored in db
05:48 technomancy  huh, nice. I've only seen that done is postgres
05:48 technomancy  *in postgres
06:48 RealBadAngel hi jin_xi how the particles are doing?
06:50 RealBadAngel technomancy, thats the beauty of this solution as you can see in the examples. storing tables in db is as easy as assigning them to another variable
06:51 RealBadAngel from modders point of view theres no differnce youre working on local or db variable
06:53 technomancy  very cool
