Context: I am working on a set of bindings, and many of my functions refer to the “global” Lua state. (It is not actually global in the code I am developing, but Local to a specific runtime instanc

Lua is a small scripting language. It is a research group in the Pontifical Catholic University of Rio de Janeiro, Brazil, composed of Roberto Ierusalimschy, Waldemar Celes and Luiz Henrique de Figueiredo and developed in 1993. Its design purpose is to be embedded in the application, so as to provide flexible expansion and customization functions for the application. Lua is written in standard C and can be compiled and run on almost all operating systems and platforms. Lua does not provide a powerful library, which is determined by its positioning. Therefore, Lua is not suitable as a language for developing independent applications. Lua has a simultaneous JIT project that provides just-in-time compilation on a specific platform.
Pit in the regular expression in Lua

Lua 4.0 Unconfirmed variables and conditional statements
This code confuses me.
print(gogo)
if (gogo == true) then
print(“yes”)
elseif (gogo == false) then

LUA can support uncounting method calls?
I am using Lua as the data description language for my C application. I have a bunch of C classes that are bound to Lua using SLB 2.0. I have binding methods such as’SetPos ‘Or’SetName’. I use a ta
OpenResty Lua-Resty-Redis Package
I searched for other people’s package code, and it feels not elegant enough, mainly because the timing of calling set_keepalive is not good.
The code below myself uses coroutine, and set_keepalive
Sort Array in Lua

Lua – reading documentation to an array
Sorry, I am still learning Lua. You can correct me, why the data in the file is not read line by line?
