New favorite of development languages on the mobile ISO platform: Lua Language

When mobile development becomes a hot technology topic, it will surely drive the rise of some new technical hotspots. Previously, Lua language was not widely used, because of its flexible, lightweight, and efficient efficiency, it has become a new favorite of the ISO platform.

TietongProgramming LanguageStatistics on popularity rankings come from Google, Bing, and Yahoo! And other mainstream search engines, as well as recruitment information released by major technical websites, largely represent the popular trend of programming languages. In this month's Tianyi programming language ranking, Lua entered the top 10 ranking for the first time.

Lightweight scripting language Lua is becoming increasingly popular among developers, which is closely related to the increasing development of mobile applications. The mobile platform, represented by the iPhone, provides many developers with new application display spaces and brings huge business opportunities to support IOS application development. Including the successful game Angry Birds.IPhoneAnd popular iPad apps both use Lua as a game script.

The biggest advantage of Lua lies in its lightweight scripts and efficient operation efficiency. This unique advantage makes Lua very useful on iOS systems known for its entertainment and user experience.

The little Lua language comes from an experimental project launched by the Catholic University of Rio de Janeiro in 1993. The Lua syntax is concise and elegant, and the interpreter is compiled by standard C. Lua, known for its fast and small sizes, has the fastest running speed among all the current script engines. This feature makes Lua the best choice for embedded scripts.

LuaCodeIt can be compiled and run on almost all operating systems and mobile terminals. At the same time, Lua provides luajit Project (luajit.org) to provide developers with real-time compilation functions for specific target platforms, the execution efficiency of Lua is further enhanced.

The original intention of Lua is not to build a complete application, but to embed it into the application.ProgramIt provides flexible extension and customization functions for applications. Therefore, Lua only provides basic mathematical operations, string processing functions, and other functions. It does not cover all aspects of programming.

In terms of language compatibility, Lua initially aimed at C and C ++ with a wide range of application scenarios, allowing the code written in C/C ++ to conveniently call the Lua script, c/C ++ functions can also be called in Lua scripts. The good interaction with C/C ++ Code gives Lua a broad application foundation in application development.

Lua's most popular application scenario is to use the script in the game as the processing logic, that is, to compile the game's task script, to achieve the configurable and scalable game. In the game, you do not need to restart the server to load the Lua script. Although the script runs less efficiently than the compiled binary code, the current CPU speed can allow the Lua script to be quickly interpreted and executed.

In online games represented by World of Warcraft, almost all plug-ins are written using an interpreted script Lua. The core C ++ Code only accounts for a small portion of all code.

Currently, the latest version of Lua is 5.2 Beta. If you want to embed a Lua script in mobile application development, after you are familiar with the syntax, you can move to the Lua open source project site luaforge.net or Lua developer site lua-users.org wiki library, download the Lua program script of interest, open the Lua script learning journey.

In the field of e-commerce, various fashionable concepts and terminologies are always emerging. Following B2B, B2C, and C2C, o2o (online-to-Offline), as a new e-commerce model, has become popular overnight and is sought after by all parties.

O2o reflects a trend of Internet business models. It is an online assistant researcher from the Chinese standardization research institute and is engaged in information technology standardization research.
