![]() ![]() Many SDKs that use Lua for programming like Corona SDK has deprecated the use of this. But it is advised on to use the older version of the code and it is assumed to less secure. When we run the above, we will get the same output. ![]() The usage of modules in a is shown below. This was used in Lua versions 5.1 and 5.0. Let me now rewrite the same example in the older way, which uses eall type of implementation. VirtualDub's author, which hosts VirtualDubMod's forums, claimed that development had been abandoned. History Version 1.5.10.2 (build 2542) was released on 21 February 2006. It is a best practice to return modules for require function and hence the module should be preferably implemented as shown above eventhough you can find other types of implementations elsewhere. VirtualDubMod was an open-source video capture and processing tool for Microsoft Windows, based on Avery Lee's VirtualDub. Module name and its file name should be the same. Place both the modules and the file you run in the same directory. When we run the above program, we will get the following output. In order to run this code, we need to place the two Lua files in the same directory or alternatively, you can place the module file in the package path and it needs additional setup. Now, in order to access this Lua module in another file, say, a, you need to use the following code segment. Let's call this module as mymath and filename being a. The city of Las Vegas in Nevada, États-Unis, has 418 public charging station ports (Level 2 and Level 3) within 15km. Let us consider a simple example, where one function has the math functions. The require function just assumes the modules as a chunk of code that defines some values, which is actually functions or tables containing functions. It is kept as simple as possible to avoid having too much information on module to load it. Lua has provided a high level function called require to load all the necessary modules. In the above sample code, you can see how flexible programming in Lua is, without any special additional code. Local formatterFunction = printFormatter.simpleFormat Local formatter = require "printFormatter" ![]() Also printFormatter has a funtion simpleFormat(arg) Assuming we have a module printFormatter Due to this free mechanism of modules in Lua, a user can call the functions in Lua in multiple ways. As a result of the ability to manipulate modules, it provides extra features for which other languages need special mechanisms. The usage of tables in modules helps us in numerous ways and enables us to manipulate the modules in the same way we manipulate any other Lua table. Also, a well behaved module has necessary provisions to return this table on require. All these functions and variables are wrapped in to the table, which acts as a namespace. This module can consist of a number of functions and variables.
