Yup. It's lean, clean, and nice to work with.

>>60131573
I prefer Lua over Python

>>60132306
So, yes?

I wish there was a scheme as small and easy to embed as lua. Protip there isn't don't even bother trying to prove me wrong

seriously don't step foot in any lua forum, just use rust if you want to surround yourself with evangelists without getting brain cancer

Lua is fucking awesome. BRs did it right.

It has uses. But remember, it is an embedded scripting language. In this case, you don't have to reinvent the wheel, you can simply use the host application's wheel.

>>60131573
yes

never liked it ever, but it's fairly widespread
kind of wish all the things that used lua had python in them instead

>>60136161
but lua is just a better python

>>60131573
Not really.

Lua was never ever ever a good general scripting language, only an embedded one.

Most people are stuck on Lua 5.1 because of LuaJIT, which is a dead project struck in maintenance mode. Lua 5.2 broke working code for no reason with its environment change, and Lua 5.3 introduced 64-bit integers and native bitshifting operators and not much else worth upgrading for.

If you're going to embed a language in your software, use Javascript, even if you hate the language. You can start with a lightweight Lua-style implementation like Duktape or JerryScript, and then when you need speed V8, Spidermonkey and JSCore are there waiting for you with several companies worth of engineers working on all three that won't abandon it like LuaJIT.

>1 indexed lists

>>60136342
Complaining about 1-indexing is useless bikeshedding, and something a sufficiently mature programmer can learn to deal with.

>>60136342
no interpreted language has real arrays anyway.

>>60136342
Tables are hybrid data structures. In all common implementations since 5.0, tables can have a hash map and array section.

>>60133176

>>60136397
>The programmer should adapt to shitty tools instead of using better tools

>>60136416
Python has real arrays

https://docs.python.org/3/library/array.html

>>60136483
No, python has something that looks like arrays.

>>60136483
So does Lua. If you use a table like an array, it's just an array.

https://www.lua.org/source/5.1/ltable.c.html

And if you absolutely need an array you can use FFI types.

>>60136245
>luajit
Isn't plain lua already faster than every other interpreted language?

>>60136512
Oh wow, that seems silly as fuck. The only reason I can see for jamming arrays and hashes into a hybrid data type is "being friendly to non-programmers".

Being "friendly to non-programmers" is how you end up with shitty languages like PHP.

>>60136483
>an object type which can compactly represent an array

Bravo.

>>60136552
>>60136557
LuaJIT can compare to like slower java/C stuff.

>>60136483
>>The programmer should adapt to shitty tools instead of using better tools
1-indexing in and of itself is a bikeshed feature that matters very little in the grand scheme of things. People complaining about such things can be safely ignored because they care too much about surface-level features and can't be trusted to have valid opinions about real problems a language might or might not have.

>>60136342
>>60136598
1 Indexes actually make perfect sense when you don't have real offsets anyway.

>>60136552
I'm guessing because it was easy enough to work with and understand, allowing even idiots to work with. Now it's just ubiquitous enough for every gamedev to use it as a scripting language.

PHP at least has managed a major version upgrade without breaking huge swaths of peoples code for no gain.

>>60136598
>Defining 1 + 1 to equal 3 is a bikeshed feature that matters very little in the grand scheme of things.
There are mathematical reasons for using 0 indexing. 1 indexing also fucks up length calculations

>>60136624
PHP isn't friendly to anyone.

>>60136630
Only if you're actually accessing sequential memory, otherwise it's all arbitrary. 1 indices describe what array-lookalikes actually do, 0 indices do not.

>>60136630
Anything that can be expressed with a 0 index can also be expressed with a 1 index.

>>60136647
Have you not read Dijkstra?

http://www.cs.utexas.edu/users/EWD/transcriptions/EWD08xx/EWD831.html

>>60136733
An array with 1 entry does not have a length of 0. It doesn't involve intervals.

>>60136647
>>60136728
0 indexing is for mathematical reasons, not architectural reasons. It doesn't matter whether or not the lists are backed by a contingent block of memory, the math works out for 0 indexed arrays.

Fucking kids these days, probably haven't even studied calculus.

>>60136798
It's 100% for architectural reasons in languages that have sequential memory based arrays. The mathematical stuff came later.

>ROBLOX consistently topping over Gary's mod and almost everything else below the top 8 on Steam's stats

>That is ugly


This is Dijkstra's core argument.

>>60136733
Yes, I read that too. He is correct that 0-indexing makes certain types of expressions more convenient. But that's all it is, a convenience, and only in certain circumstances.

This isn't the only time I've had to deal with Dijkstra-derived stupidity peddled by novices, his diatribe against goto should have a gigantic fucking asterisk next to it as well. I swear I will shoot somebody the next time I have a pull request rejected asking me to justify the use of goto in a state machine or in cleanup code.

You code the engine and performance critical code using c/c++ and then use lua to script the game.
Lua is relatively fast and easier to write scripts than c.

>>60142344
lua patterns are good enough for most uses. also there are regex libs and other powerful pattern matching libs.

>>60132946
S7 works well enough for embedding

>>60137004
C# API is also god-tier

doesn't it not have a proper library and is missing some features

>>60145638
no

>>60142344
It has Lpeg, a popular library for portable expression grammars. It includes regex too. PEG are superior for anything complicated and patterns are good enough for anything simple.

>>60137004
Lua is great. Shame there's three different versions in common use and they're all different and incompatible in various ways.

>>60146179
lol no, this isn't python. Lua 5.1 is standard til the next major version.

I'm still waiting for luajit to work properly when shit is allocated beyond 4gb of address space in a 64bit process.

>>60146290
>Lua 5.1 is standard til the next major version.
Unless you use LuaJIT, which includes 5.2 changes. Or you actually want to follow the real standard which is 5.3. Walking about with semantics and pretending that 5.1 is supported in any capacity is just embarrassing.
>>60146858
Is a pretty fucking good example.

>>60147620
LuaJIT mostly doesn't do 5.2, that's WHY 5.1 is standard. 5.1 is major release + immediate patches. Anything past that is pre-release lua6 stuff and should be learned but avoided in use.

>>60131573
Good for when I'm making my roblox game 10/10

>>60147724

>>60150047
Good for you, kid.

Lua is meh but it's the most documented and fastest scripting language we have available for embedding.

There is wren which looks interesting but the docs are limited.
