| 11:40.45 | cocovanana | Hi everyone! Just started developing some addons, and I had a couple questions; |
| 11:41.48 | cocovanana | - What exacltly is upvalue? I saw someone ask if it was something like "local _G = _G", but didn't get a reply. Answers I get from google are a tad too overengineered I think |
| 11:42.59 | cocovanana | - What is the default bag addon/frame? I found the BankFrame on FrameXML, but not the one for bags (or inventory)? |
| 11:43.45 | cocovanana | - What exactly is the ... at the start of an addon? I get the first value is the addon name, but the second? It's just an empty table for your local stuff, or how does it work exactly? |
| 11:43.59 | AcidWeb | 1. You moving something from global namespace to local namespace. That make it less expensive to call. |
| 11:44.23 | AcidWeb | 3. That empty table is your addon namespace. It is shared between all files of your addon. |
| 11:44.57 | cocovanana | Thanks! |
| 11:45.05 | nevcairiel | An "upvalue" specifically is a local variable of a higher scope (hence "up"), typically on a file level, some people use it to cache globals since its cheaper to lookup an upvalue, but its probably not a measurable difference, so just don't worry about it |
| 11:45.43 | AcidWeb | Also this might help: https://www.lua.org/gems/sample.pdf |
| 11:45.45 | cocovanana | Why is it so in (1)? Usually I'd expect accessing a variable directly cheaper than having to store a local copy etc. |
| 11:46.22 | nevcairiel | accessing a global variable requires accessing the global scope, which is just more expensive then accessing any local scope |
| 11:47.43 | cocovanana | Okay, thanks! |
| 11:48.26 | cocovanana | And thanks for the link too! Will definetely take a look, since I'm used to C++, but many things are different in Lua |
| 11:51.21 | cocovanana | Just read the registers stuff; completely explains the local vs global :) |

| 12:40.54 | foxlit | Rule #1: "Don't do it." |
| 12:44.01 | foxlit | The cost of a global lookup is insignificant compared to everything else you might be doing; the only place where you'd want to do local Foo = Foo for perfroamce reasons is immediately before a for i=1,1e6 do loop that uses Foo. |

| 13:39.49 | Ennea | nevcairiel, does wowace have pull/merge requests? i'd like to make one for libactionbutton.. uhh, later, i guess |
| 13:39.53 | Ennea | i haven't actually touched the code |
| 13:40.22 | Ennea | there's a key difference between it and the default ui, though. default ui invokes actions on keydown for hotkeys, but mouseup for clicks |
| 13:40.29 | Ennea | with LAB, i can only set it to down or up for both |
| 13:41.28 | Ennea | oh, actually |
| 13:41.34 | nevcairiel | the default UI cheats though |
| 13:41.54 | Ennea | i suppose this is partly due to the default setup setting hotkeys for :LeftClick with libkeybound |
| 13:42.19 | Ennea | how does it cheat? |
| 13:42.40 | nevcairiel | it doesnt use the secure frames, it just calls stuff directly, more freedom |
| 13:42.49 | Ennea | ah |
| 13:42.51 | Ennea | ^^ |
| 13:55.51 | *** join/#wowuidev TukuiDevs1 (~TukuiDevs@45.32.153.30) |
| 14:35.06 | Ennea | is there a way to create a keybinding that clicks a secure button and runs some other code? so instead of creating a CLICK buttonname:LeftButton binding, create a regular one that does that and.. something else? |
| 14:35.11 | Ennea | i'm guessing not |
| 15:02.16 | *** join/#wowuidev mikma (mikma@kinky.fi) |
| 15:18.54 | Ennea | nevcairiel, my solution to the down vs up problem was creating an additional secure button, registering it for 'AnyDown' clicks, settings its type to macro and its macrotext to /click <otherbuttonhere> |
| 15:19.05 | Ennea | basically, each of my button has a second, invisible button for it |
| 15:19.23 | Ennea | and i changed the LAB buttons' keyBoundTarget to point at the invisible one |
| 15:19.24 | nevcairiel | i dont really mind the behavior |
| 15:19.49 | Ennea | so now i have keydown for hotkeys, and mouseup for any mouse interaction |
| 15:20.27 | Ennea | well.. i absolutely wanted the keydown behavior, since it just makes sense to have it |
| 15:20.34 | Ennea | and the default action buttons behave like that, too |
| 15:20.49 | Ennea | but setting clickOnDown to true with LAB also invokes the button on drag, which is a pain in the ass |
