04:48 can-ned_food not I, sorry
04:48 Joee         okay

08:46 IhrFussel    Why is damage NIL in on_punchplayer() ?
08:54 IhrFussel    I'm trying to get the TOTAL damage from a hit and want to add to it based on a table value ... but damage is nil it seems
08:56 IhrFussel    The Lua API also doesn't mention anything about the "damage" parameter
09:10 IhrFussel    WAIT...are you telling me that you cannot register when a player punches an entity??
09:31 Krock        IhrFussel, huh? there's "on_punch"
09:33 IhrFussel    Krock, I meant a general way to get the total damage a player did to an entity but I guess there isn't...doesn't matter now I modified the Mobs Redo mod in a way that it directly calculates the table value inside the damage handler
09:34 Krock        you can clculate the damage using tool_capabilities
09:36 IhrFussel    Yes but I thought I wouldn't have to calculate the damage between entities and players separately
09:36 IhrFussel    register_on_punchplayer() doesn't fire when a player hits an entity AFAIK
09:36 Krock        the mobs redo already calculates the damage here: https://github.com/tenplus1/mobs_redo/blob/master/api.lua#L2052
09:37 Krock        yes, they're handled seperately
09:37 Krock        but you could write a generic wrapper to redirect both callbacks into your own function
09:37 Krock        which then could handle players and entities the same way
09:38 Krock        on_punchplayer only differs from the entity on_punch by its damage param
09:50 IhrFussel    Setting the nametag text only won't affect its color right? Like this plo:set_nametag_attributes({ text = "L."..level[pn].."\n"..pn })
09:52 Krock        depends if the color can be specified seperately
09:52 Krock        because you couldn't do this with chat messages, as they're colored in-text
09:54 IhrFussel    I will try it I guess
09:58 IhrFussel    Krock, it works, the color is unaffected
10:12 Krock        great
10:59 IhrFussel    Krock, well actually I'm not so sure...the player I asked seemed to be a bit confused when I asked him if my name is still colored
11:01 Krock        outdated client
11:02 Krock        or a very sophisticated one - as you can read his mimics to see if he's confused
11:04 IhrFussel    That's pretty simple... "Umm...?" is enough to see that the person is confused :P
13:11 WSDguy2014   I saw at the end of the changelog for 0.4.16, why is there a "Minetest Game changes"? It's empty here. It's still work in progress?
13:12 sfan5        nobody has taken the work of writing the changelog yet
13:37 red-001      ^
15:19 IhrFussel    If a file exists but is empty Lua sees it as NIL?
15:20 IhrFussel    I mean the file handler doesn't return nil but read() does
15:27 calcul0n     IhrFussel, it's normal, read returns nil on EOF
15:28 agaran       hi IhrFussel
15:28 IhrFussel    That's still weird...it caused many server crashes cause I honestly didn't expect a NIL when a file is empty
15:29 IhrFussel    Hello agaran
15:31 calcul0n     why is it weird ? if it's empty you just reach eof immediatly
15:31 IhrFussel    calcul0n, but empty != nil
15:31 IhrFussel    local bla = nil is also not the same as local bla = "" AFAIK
15:32 calcul0n     yes, but as read() reads line by line, you wouldn't be able to make the difference between eof and an empty line
15:32 agaran       IhrFussel: it is not, but "" takes memory, returning 'nil' takes less..
15:33 agaran       zero byte string needs to be returned as unique copy of such object, nil can be singleton, you won't be appending to it.. (and operator can be overloaded to return valid stuff if you do anyway)
15:33 agaran       well it is lua.. expect unexpected :)
15:33 IhrFussel    Yes but my point is: Why does read() handle it so different from the rest of Lua? That is confusing
15:35 sfan5        read returns "" for empty files
15:35 sfan5        you are doing something wrong
15:35 calcul0n     it returns nil here
15:36 Fixer        Can't attach anything on github issues... pics/gifs/etc... newest Firefox. Is it only me?
15:37 Fixer        for quite long time
15:37 Fixer        is broken since some time
15:37 agaran       sfan5: could you please show your test code maybe it is lua version related?
15:37 sfan5        it does not https://a.uguu.se/XnM38acSQDRx_Bildschirmfoto_2017-06-18_17-36-48.png
15:38 agaran       sfan5: on 5.2 that example does not work..
15:38 agaran       > content = f:read("a*")
15:38 agaran       stdin:1: bad argument #1 to 'read' (invalid option)
15:38 agaran       stack traceback:
15:39 sfan5        it's *a
15:40 agaran       right, my bad
15:40 calcul0n     same here, "*a" works in 5.3 but not in the minetest version
15:40 calcul0n     which is 5.1 iirc
15:40 sfan5        you're right tho it returns nil in 5.2
15:40 calcul0n     here it returns "" with "*a" but nil with no argument
15:41 IhrFussel    It returns nil on my PC too "echo -n "" > test.txt in Bash then local lch = (io.open("/home/emmanuel/test.txt", "r")); print(lch:read()) >>> nil
15:41 agaran       sfan5: it just screams, we need regresion testing.. for LUA dev..
15:41 sfan5        you are not supposed to call read without arguments https://www.lua.org/pil/21.1.html
15:42 sfan5        it seems like lua changed this behaviour with 5.3
15:42 IhrFussel    The point is read() is supposed to READ the file contents...and an empty string is STILL content IMO
15:43 calcul0n     This pattern is the default for read, so io.read() has the same effect as io.read("*line").
15:43 agaran       IhrFussel: it is just lua weirdness.. you can only prepare your code to be resitant to this..
15:43 calcul0n     but yes, 5.3 seems very different
15:44 IhrFussel    My PC has Lua 5.2.4 btw
15:44 agaran       and what lua version you used to compile minetest with?
15:44 sfan5        minetest can only use lua5.1 or luajit
15:44 IhrFussel    MT uses 5.1 or not?
15:46 Calinou      IhrFussel: Minetest supports only Lua 5.1
15:46 Calinou      don't use 5.2 or 5.3-specific features
15:46 Calinou      (this is also because LuaJIT supports only 5.1 at most)
15:48 IhrFussel    Calinou, I didn't use any 5.3 features...it simply confused me that Lua wants to try to tell me that an empty EXISTING string can be "nil"
15:48 sfan5        it doesnt return an empty string
15:49 IhrFussel    But it READS an empty string, so I expect it to return an empty string ... it's bad behavior that it doesn't
15:50 calcul0n     as i said how would you tell if you reached eof or just read an empty line ?
15:50 calcul0n     if the file is empty it just contains nothing, that makes sense to me
15:51 IhrFussel    Yes it contains nothing but nil means "not initialized" or not?
15:52 calcul0n     well, it means "nothing"
15:52 IhrFussel    NIL = non-existent usually
15:52 calcul0n     so, you're reading non_existent datas, what's wrong ?
15:53 IhrFussel    I was told that empty != non-existent in Lua here recently ... so this behavior is unexpected
15:57 IhrFussel    But it doesn't matter now...this stupid behavior crashed my server quite a few times today and NOW I know that read() will be nil if the file has no contents

18:07 Joel___      Hi
18:55 Hijiri       IhrFussel: read without any specifiers means "read a line"
18:56 Hijiri       not "read the file"
18:56 Hijiri       there are no more lines, so it returns nil
18:56 Hijiri       I don't see how this goes against convention
18:58 Hijiri       oh wait no, it returns empty string for reading a line of empty file at first
18:58 Hijiri       but that is because the file follows the convention of having a newline before EOF
19:00 Hijiri       When I remove the newline before EOF it returns nil on first read()
19:03 sfan5        Hijiri: read("*a") returns nil for empty files
19:03 sfan5        whether it should do that is a matter of definiton
21:09 lastly       its been a few years and versions since I've played MT, but just installed again and unified-inventory is not allowing me to use the sethome, gohome, day and night buttons in the inventory formspec. Anyone know a quick fix for this or am I doing something wrong?
21:39 Joel___      i need help with vehicle_mash
21:40 Fixer        lastly: you probably don't have needed privs
21:40 Fixer        lastly: if in singleplayer: /grantme all
21:40 Joel___      Fixer can u help me with vehicle_mash mod?
21:40 Fixer        nope
21:40 Fixer        no idea
21:42 lastly       yeah, tried /grantme all.. still not working
21:43 Fixer        lastly: rejoin
21:44 lastly       thank you very much.. that worked.. I feel kinda dumb now... when something isn't working, turn it off and back on
21:44 lastly       how simple
