00:08.12blast007so... given that knowledge, and since we were planning some major refactoring to migrate to GL 3.2 anyway, would it be wise to consider this?  https://github.com/bkaradzic/bgfx
00:10.51spldartwonders what percentage of bzflagers are on apple products :(
00:11.21blast007roughly 20 to 25 percent
00:11.32spldartHoly crap! I had no idea
00:12.02blast007that's a real rough estimate
00:12.08spldartunderstood
00:12.30blast007historically it's been about 50% Windows and then a close split between macOS and Linux
00:13.17spldartI had always assumed 75% was prolly windows considering it's ubiquity.
00:13.48blast007Windows users have far more options for games to play :)
00:14.13spldartTrue. :>
00:14.16spldart:(
00:17.40blast007the build process for bgfx is a bit ... interesting

02:28.43macsformeI think OpenGL 3.2 is still fine... I doubt Apple will drop support until 3-4 macOS versions from now, and by then there will probably be multiple options for compatibility layers (if we even care)
02:29.45JeffMIf they are even on x86 then
02:29.47macsformebut for sure it seems like a silly move for them... but so was dropping all other ports except USB-C on their laptops
02:30.14macsformetrue... although bz does run fine already on ARM :)
02:30.22JeffMSure
02:31.44JeffMThey said they were not merging os’s but I think they are just saying that they will keep them branded separately, but they will start to move to common core components
02:33.31macsformeI wonder if they will deprecate OpenGL ES support from iOS too...
02:33.59JeffMI’d they can swing it
02:36.42macsformemaybe there are a lot more iOS games on OpenGL ES than macOS games on GL... it would be like they had "courage" to remove standard USB ports from their macs, but not from their more lucrative phones
02:37.21JeffMMaybe
02:38.46blast007does macOS support GL ES?
02:40.26macsformeit's almost a subset of GL, so you could almost write code that will work on both
02:44.23JeffMBet the next Mac mini is going to be a giant iPad
02:52.32*** mode/#bzflag [-v short_circuit] by ChanServ
02:58.47blast007they'll probably just remove all the ports from the next mac mini except for the power connector

03:01.43JeffMOpenGL es was deprecated on iOS as well
03:01.53blast007welp.....

20:58.44ZehraThis is probably a simple issue in a plug-in, but I'm not sure why it is not working.
20:58.52Zehrahttps://pastebin.com/FVTvU1rR
21:00.37ZehraHere is the configuration file: https://pastebin.com/4NxekQwK
21:01.21ZehraIt works perfectly when everything is hard coded, but does not work when using the configuration file. :/
21:01.46ZehraI get errors, but from all my checking, I don't find anything which should cause the issue.
21:02.55ZehraReordering the configuration items and renaming the configuration items in the configuration file and plug-in was done, without any luck.
21:06.44blast007Zehra: do you know that arrays exist?
21:08.12Zehrablast007: Yes, but this worked hard coded, so I just decided to try to convert it to one which could be configured.
21:08.36*** join/#bzflag gartral (~gartral@162.243.117.98)
21:09.03Zehra(It could be better written, that is for sure, but I tried to stick with what works or used to work for now.)
21:09.51blast007run it through the debugger, set up some breakpoints, inspect the data
21:10.53ZehraWill do.
22:01.30JeffMthat is some of the most amateurish and least maintainable code I've ever seen.
22:02.21JeffMit physically hurts me
22:03.05allejohands JeffM a bandage
22:05.16ZehraWhen it's badly written, it's my code. :p
22:05.37JeffMI can't even tell what it's supposed to do...
22:05.54JeffMwhat is the point of mainFlag = config.item(section, "mainFlag"); ?
22:06.13JeffMto get flags out of a config?
22:06.29ZehraYes.
22:07.18ZehraIt basically is supposed to be a version of progressive flag mode, except instead of zapping flags, it just allows or denies them.
22:07.21JeffMand if one type is not an int, none of the rest of them load?
22:08.11JeffMyou should learn about arrays, vectors, and structures.
22:08.33blast007and then use something other than our config loader for that
22:08.52blast007like, yaml-cpp
22:10.20blast007our config loader isn't designed for loading a variable number of items
22:10.34allejoyaml-cpp <3
22:10.48Zehraoh, okay.
22:10.59JeffMhow does it store stuff? in a map?
22:11.07JeffMahh a map of maps
22:11.30allejomy first experiment with testing yaml-cpp in a plugin, https://github.com/allejo/relativeBZDBValues/blob/master/relativeBZDBValues.cpp#L66-L186
22:12.07allejoyaml-cpp's API is pretty neat for casting stuff into structs/classes
22:13.00JeffMit's trivial to extend plugin_utils to provide a list of pairs
22:13.25blast007INI just isn't very flexible
22:13.47JeffMsure, but you've already GOT a variable list, it's just not being exposed
22:14.20allejoyah, make things loopable
22:14.38JeffMit's already based on standard containers

22:16.17Zehragoes to make a rewrite of their plug-in
22:16.57allejohonestly, you could just come up with a simple syntax. e.g. https://github.com/allejo/timedFlagOnSpawn#usage
22:17.15allejohere's the respective parsing, https://github.com/allejo/timedFlagOnSpawn/blob/master/timedFlagOnSpawn.cpp#L197-L259
22:17.58JeffMhttps://www.irccloud.com/pastebin/qh4fLUqp/
22:21.25ZehraI saw a few examples of different syntax, but having 30 or so items in a plug-in would have been a bit much.
22:21.46Zehra(Especially for my lack of experience in parsers.) :p
22:22.40ZehraI wish I could be able to come up with a much simpler syntax and cleaner code too.
22:23.02JeffMyou don't need 30 items
22:23.10JeffMyou need a structure and a container
22:23.26blast007that would actually be a very good situation to learn
22:23.31JeffMyeah
22:23.40JeffMI'm going to write a good one, and then not show it to you so you can learn
22:23.45blast007you have a problem you want to solve, and by solving it you can learn more about coding
22:26.38allejoon a semi-related note, is the 2.4 branch frozen to new stuff? is it worth pushing the code to expose all the keys in a config?
22:27.12JeffMthose arn't keys
22:27.19JeffMthey are pairs
22:28.17allejopairs meaning there can be duplicates?
22:28.26JeffMno, they are key value pairs
22:28.37JeffMit's a map of maps
22:28.52JeffMa map can be thought of as a vector of pairs
22:29.22allejoright, i meant just exposing the list of keys from the INI file so you can use the already existing `config.item()`
22:29.31allejoand not list them as an std::pair
22:29.35JeffMsure
22:29.43JeffMI've added that too
22:29.52JeffMyou'll see when I show this to you.
22:29.56JeffMbut not Zehra
22:30.47allejoah you're already adding it to PluginConfig?
22:31.00JeffMmy copy
22:31.22JeffMit's super easy
22:31.26JeffMalmost done
22:31.35JeffMbarely an inconvenience.
22:32.12allejolol
22:33.07JeffMdoes have to reemember how to write lambdas in C++
22:33.56allejothis isn't going into 2.4, is it?
22:34.25JeffMfine.. I use a map
22:35.07allejoit'd be fine for 2.6 but don't think we have any lambdas in 2.4.x. heck, we can't even do a range for loop because of gcc min reqs :p
22:35.25JeffMoh I'm doing the hell out of range based for ;)
22:35.46JeffMport it as needed :)
22:37.10JeffMugg I know too many langauges...
22:37.32JeffMI keep doing std::vector<FlagData> vec = new std::vector<FlagData>();
22:38.31allejolol
22:39.03JeffMdone, 92 lines for the plugin
22:39.23JeffMwith error checking
22:40.01JeffMAdd these to plugin_config and it'll have more options. https://www.irccloud.com/pastebin/UZBwLmBq/
22:40.49allejodon't you have commit access now? :p
22:41.26allejowait nope. no range-based fors
22:42.21JeffMI'm going to commit that to master
22:42.30JeffMif you want it in 2.4, just convert it to a regular for
22:42.37allejofair
22:42.53JeffMfor (auto itr = sections.begin(); itr != sections.end(); itr++)
22:44.27JeffMin the plugin I let the key of the seciton item be the flag name, and the value be a comman seperaated pair of scores: min,max

22:50.42JeffMso there ya go Zehra it can be done better, see what you can come up with :)
22:52.59JeffMthe config would look like, [Flags]
22:52.59JeffMGM = 1,3
22:52.59JeffMSR = 4,6
22:52.59JeffMSB = 7,9
22:54.48ZehraI have a bit of an idea which might work for my rewrite. :)
22:58.40JeffMdescribe it
22:58.46JeffMtalk it out before you write it
22:59.34ZehraI'm thinking of having two structs, one for the flags which can always be grabbed at anytime and the other for ones having a certain requirement in points.
22:59.57JeffMyou don't need 2
23:00.06JeffMthe first set is assumed to be all flags that are not in the second set
23:00.07Zehraoh, okay.
23:00.16JeffMif it's not in the score list, it's available
23:00.29JeffMwhy do you need a list of them?
23:01.43ZehraI kind of want to prevent players from grabbing flags, unless it is flagType and it meets the point conditions or is one which should always be grabbed.
23:01.53Zehra(allowed to grab.)
23:02.06blast007why have flags on the map they can't ever grab?
23:02.48JeffMthat
23:02.49ZehraLike it would be progressive flag mode, but instead of zapping flags, I could allow or prevent them from grabbing it.
23:02.57JeffMstill, you don't need a list
23:03.06JeffMthat's just different logic for if it's not the in list
23:03.09blast007yeah, but why do you need a list of flags that people can always grab?
23:03.14JeffMdeny if it's not in the list.
23:03.25JeffMyeah it's not good for the end user to see flags they can NEVER grab
23:03.42JeffMyou could delete those flags
23:03.48allejothink of it as a ban list
23:03.57allejoyou don't ban everyone and just allow certain people in
23:04.00JeffMwell it's a allow list.
23:04.11Zehrayes, so like I prevent them from grabbing certain flags, unless the right conditions are met...
23:04.12JeffMhe's worse than that
23:04.20JeffMhe's allowing banned people to connect but never play :)
23:04.29Zehra:P
23:04.31JeffMZehra: conditions sure
23:04.41JeffMbut if a flag is NOT in the list of conditions, can it be grabbed?
23:04.50ZehraNo.
23:04.55JeffMthen why is it on the map?
23:05.35ZehraThat's for the map maker to decide or configure the plug-in.
23:05.58JeffMthe plugin should be able to remove those
23:07.04JeffMor I guess there is no aAPI for that
23:07.06ZehraI'm not sure if I can remove flags with a plug-in.
23:07.08JeffMthat's lame
23:07.15JeffMProto tollay supports that
23:07.32ZehraMaybe zapping them would work, like zapping them under the world. :P
23:08.11JeffMwell still, you don't need 2 lists, just logic for what to do when a flag is not in the list
23:08.23JeffMI had mine allow the flag if it wasn't in the list
23:08.31JeffMso the server op coudl say "everyone can have ID" or something like that
23:08.56Zehraoh, okay.
23:09.29JeffMthe core of my event handler, is 6 lines of code that do all the work
23:10.13ZehraI'm assuming you are using a loop for this.
23:11.01JeffMnope
23:11.05JeffMno loops
23:11.21JeffMjust a lookup
23:11.37Zehraack, that is how I was going to do it.
23:11.49JeffMwell there is a single loop when reading the config
23:12.08JeffMthe STL has all the algorithms you need.
23:12.19JeffMFlags.find(std::string(grabData->flagType));

23:12.52JeffMI know
23:13.03JeffMthat's the point to force you to GET familiar with it
23:16.38JeffMso your code doesn't load when there is a config?
23:16.59JeffMdoes it say your config has errors?
23:17.32ZehraThe one which was put on pastebin says my configuration has errors.
23:17.58JeffMdo you see why?
23:18.24ZehraNope. :(
23:18.27JeffMit has nothing to do with your config
23:18.42JeffMwhat is config.errors ?
23:20.26ZehraI saw this in another section, and tried to implement it.
23:21.05ZehraBut I guess something went wrong along those lines. *looks at their code*
23:21.41JeffMjust go read it
23:21.48JeffMgo see how you are using it
23:21.58JeffMit doesn't even make sense when you read it.
23:22.14Zehrayikes
23:22.25JeffMall you have to do is READ your code
23:22.50JeffMyou probalby want if (config.errors > 0)
23:34.27Zehraty JeffM
23:36.52blast007but still fix your plugin
23:37.27ZehraWill do, making a rewrite of it.
