Talk:Lua Programming

Merge with Lua Programming / Embedding Lua / Lua components written in C&C++

I support the merge of Lua programming and Lua Programming, with Lua programming's content largely superseding Lua Programming's. Lua Programming does have a section called 'solutions' which suggests there should be pages about writing Lua components in C and C++ and embedding and embedding Lua in C and C++.

Programming Solutions

I notice that you have removed the "programming solutions" section. This has left a hidden section "solution"s, which is no longer accessible via the book indexes. I'll put this back for now, until the indexes are fixed.

Merger with Lua programming

The voting is happening here: Wikibooks:Requests_for_deletion#Lua_Programming Hackbinary (discuss • contribs) 13:12, 12 October 2013 (UTC)

Consensus was to merge the books. Please see Category:Book:Lua Programming for a complete list of pages, many of which are not linked to from anywhere within this book right now. --darklama 19:05, 23 May 2014 (UTC)

Translate to Chinese

I want to make a Chinese translation. Can I? ShadowYC (discuss • contribs) 01:41, 16 February 2017 (UTC)

Yes you can. Ftiercel (discuss • contribs) 19:53, 16 March 2017 (UTC)

Should we have a section on object oriented programming

Should we have a section on object oriented programming?

While Lua doesn’t have native objects, a combination of metatables (i.e. the __index property of metatables) and Lua’s “:” syntactic sugar gives us real classes with inheritance. For example:

 -- Public domain example of Objects in Lua using metatables
 -- Let’s create a class
 Add1Obj = {} -- Initialize a new class
 Add1Obj.__index = Add1Obj -- Allow class to be a metatable
 
 -- Method: Initialize class
 function Add1Obj:new(start)
   if start == nil then
     start = 1
   end
   return setmetatable({v = start},self)
 end
 
 -- Method: Add one to the class’s “v” element
 function Add1Obj:add1()
   self.v = self.v + 1
   return self.v
 end
 
 -- Example of class usage
 foo = Add1Obj:new(1)
 print(foo:add1())
 print(foo:add1())
 
 -- Now, let’s create a derived class
 Add2Obj = {} -- Initialize a new class
 Add2Obj.__index = Add2Obj -- Allow this class to be a metatable
 setmetatable(Add2Obj, Add1Obj) -- Inherit the Add1Obj class
 
 -- Derived class has a new method
 function Add2Obj:add2()
   self.v = self.v + 2
   return self.v
 end
 
 -- Example using derived class
 foo = Add2Obj:new(20)
 print(foo:add1())
 print(foo:add2())
 -- END public domain code
