Lua is cross-platform software, since the interpreter of compiled bytecode is written in ANSI C, [4] and Lua has a relatively simple C application programming interface to embed it into applications. [5] Lua originated in 1993 as a language for extending software applications to meet the
This help-page, Help:Lua debugging, explains issues of writing Lua script and debugging the source code, to remove errors or improve performance. Because Lua is a "semi-compiled" interpreted language, it does not prescreen for all common syntax errors, nor detect misspelled variables, which are only found at runtime when seeing the " Script ...
This essay explains various issues about the execution speed and performance of Lua script in Wikipedia. The speed of using Lua modules can vary greatly, compared to similar markup-based templates, often ranging from 4x-8x times faster, or 180,000x faster when scanning text strings, which can exceed the 500-character parser-function markup limit as 64,000 characters or more.
Interpreted languages are programming languages in which programs may be executed from source code form, by an interpreter. Theoretically, any language can be compiled or interpreted, so the term interpreted language generally refers to languages that are usually interpreted rather than compiled.
In a bytecode-compiled system, source code is translated to an intermediate representation known as bytecode. Bytecode is not the machine code for any particular computer, and may be portable among computer architectures. The bytecode may then be interpreted by, or run on a virtual machine. The JIT compiler reads the bytecodes in many sections ...
The conventional transformation of these language used an interpreter. While not widely used, Bash and Batch compilers have been written. More recently sophisticated interpreted languages became part of the developers tool kit. Modern scripting languages include PHP, Python, Ruby and Lua. (Lua is widely used in game development.)
Lua is a small (C source is approx. 300 kB tarball, as of version 5.3.5), portable and embeddable scripting language (with LuaJIT as a JIT compiler improving speed). It can be embedded in applications such as computer games to provide runtime scripting capabilities. [8]
There are various compromises between the development speed when using an interpreter and the execution speed when using a compiler. Some systems (such as some Lisps) allow interpreted and compiled code to call each other and to share variables. This means that once a routine has been tested and debugged under the interpreter it can be compiled ...
