📣 Just released Shöve v1.0.6!

Sometimes LESS is MORE - we saw up to 20% faster rendering on Steam Deck-like hardware by removing "clever" optimizations. Paradoxical? Check out our blog for the full performance story and benchmark results! #LÖVE2D #gamedev #LuaJIT

May seem small but #FerrousSystems donating their
#rust spec is huge.

In #lua, it's helped so much to design things like #luajit and custom embeds. 😎

Thinking about adding Lua scripting.

How does one decide between Lua 5.4, 5.3, 5.2, 5.1 (yay, LuaJIT) or Luau?

#rustlang #lualang #luajit

I didn't realize #LuaJIT had a built-in profiler. It's really cool (that I don't have to install anything to use it)!

$ luajit -jp=fla3m1 main.lua

https://luajit.org/ext_profiler.html

#LuaRocks question - how can I use it with #LuaJIT?

$ luarocks --lua-version=5.1 install --local opencl
Installing https://luarocks.org/opencl-1.2.0-1.src.rock

Warning: variable CFLAGS was not passed in build_variables
make[1]: Entering directory '/tmp/luarocks_opencl-1.2.0-1/lua-opencl/test'
/usr/bin/lua5.1 platform.lua
/usr/bin/lua5.1: ...opencl-1.2.0-1/lua-opencl/test/../opencl/C.lua:7: module 'ffi' not found

Do I need to reconfigure/reinstall luarocks, or can I make it work with both LuaJIT and Lua 5.1/5.4?

I love #Lua and #LuaJIT. I just write the most straightforward code I can think of, and my 10yo computer spits out an answer in under 10s.

I just fear this brute force approach will bite me in later stages...

#AdventOfCode

Tommy has really outdone himself on this one! The LuaJIT engine is super sophisticated, and this post goes into all the gory details of how we had to reverse-engineer it so we can profile it with zero-instrumentation!

Сейчас понимаю, что Luanti, Hedgewars и другие игры с Lua-скриптингом кладут свои яйца в LuaJIT, который в свою очередь является слешем Lua 5.1 (PUC) и бэкпортом отдельных фич из Lua 5.2+5.3. :blobcatgooglyholdingitsheadinitshands:

И всё от того, что LuaJIT создавался для ускорения Lua 5.1 через динамическую компиляцию, как потом появился оригинальный Lua 5.2, который поломал много кода. То же самое получилось и с синтаксическими плюшками в 5.3. Теперь люди просто не хотят соскакивать на 5.4, ибо JIT-компиляция нужна и есть опаска, что Lua в очередной раз сломает вещи. :blobcatgooglywhaat:

Но не спрашивайте меня: у Майка Полла есть много чего поведать об этих разноречиях.

I'm skeptical that plugins will perform better in #Neovim compared to #Vim. For example, plugins like Fugitive written in legacy VIML will likely have similar speeds in both editors. Only plugins optimized for #Luajit can achieve faster speeds, but I've only come across a handful of those, which, by the way, won't be compatible with Vim.

#LuaJit and #Julia being on par with #Rust is quite surprising.

Recovering from a week of flu. Mainlining coffee. Dusted off my old #LuaJIT #roguelike project and got the basics of a Tiled map loader working, after some frustration with learning how global ids work.

Progress is a comfortable disease.

Is LuaJIT 3.0 being actively developed? 🍿
