09:09 sfan5      anyone know whether we can tell luachekc to throw an error if someone uses a ; in code?
09:25 Mantar     don't think so, semicolons are valid in lua despite being optional
09:27 Mantar     page 1 of PIL says "a semicolon may optionally follow any statement"
09:30 sfan5      point is that they're pointless and should not appear in our codebase
09:34 sfan5      huh turns out luacheck is unmaintained since 5 years
09:38 MTDiscord  <.niklp> lunarmodules luacheck is maintained https://github.com/lunarmodules/luacheck (it's on luarocks too)
09:39 MTDiscord  <rollerozxa> the original luacheck author passed away, lunarmodules forked it
09:51 sfan5      I see
09:51 Mantar     eh, they don't have any code function, that's not the same thing as being pointless, or else we'd need to get rid of comments. semicolons can sometimes make things more readable
09:51 sfan5      google only found the original one
09:52 Mantar     but hey, I get you, style decisions have to be made for a project
10:14 rubenwardy I don't think I've ever found a case where semicolons were needed, except for code golfing
10:52 celeron55  semicolon is functionally equivalent to a newline, right?
10:55 celeron55  and lua doesn't really require newlines in silly places. for that reason, there is no need for semicolons
10:55 celeron55  the only exception is if you're given a single line editor and you need to fit your program on that line
11:35 MTDiscord  <luatic> Semicolons in Lua are very rarely "required" as a statement separator due to an ambiguity in Lua's grammar: "f(...) <newline> (expr)(...)" (and variations like "_ = f <newline> (expr)(...)" or "return f <newline> (expr)(...)" could be parsed as either "f(...); (expr)(...)" or "f(...)(expr)(...)". This happens very rarely though (think once in 10kloc). Besides that, semicolons are just a style decision.
11:38 MTDiscord  <luatic> I don't think Luacheck should become a style checker, though; it's a linter which happens to catch egregious style mistakes. We should adopt a Lua formatter (I recommend StyLua) to check & apply style.
22:06 sfan5      @appguru have you tried debugging the irrlicht segfault in a 20.04 container/vm?
22:16 MTDiscord  <luatic> sfan5: not yet, i'll try to look into it over the weekend
