Where Lua Is Used

What do Adobe Photoshop Lightroom, Angry Birds, Apache HTTP Server, Apache Traffic Server, the Firefox web browser, MediaWiki, and World of Warcraft all have in common? They are all extensible using the cross-platform Lua programming language, winner of the 2011 Game Developer Magazine Front Line Award because:

Lua has become an extremely popular programming language, so much so that it's achieved a critical mass of developers in the game industry, meaning Lua skills are transferable from company to company. That's partly due to its speed and the ease with which developers can embed Lua into a game engine.

This web page catalogs stand-alone programs that are written in or are extensible using the popular Lua programming language.

If you know of any missing apps, can provide corrections or additional detail about any listed apps that lack a description, or have any relevant suggestions, your input will be appreciated. Please post to the Lua-l mailing list. You can subscribe at http://www.lua.org/lua-l.html.

Business Logic

Business Logic — Visual Business Logic Editor Toolkit

Visual Business Logic Editor Toolkit

Visual Business Logic Editor Toolkit is a visual domain-specific language toolkit in Lua. See also slides from Lua Workshop 2013 and online demo.

It is often the case that, on one hand, there is a need to configure lots of intricate and ever-changing business logic rules, but, on the other hand, the person who has the most expertise on the particular business logic area – domain expert – often will not have a clue on how to write code effectively (or even at all). All kinds of clumsy UIs, spaghetti code, wasted dedicated scripter's hours and other unpleasantries stem from that problem.

Business Logic Editor Toolkit alleviates that problem by providing a programmer with a set of tools to easily build a business-logic configuration UI, suitable for a non-programmer domain expert, and an easy, platform-agnostic way to seamlessly tie business logic configuration from that UI to an existing (or newly written) codebase, effectively creating a visual domain-specific programming language.

The toolkit is written in Lua (plus some JavaScript) and it is a seventh generation implementation of the concept behind it. Contact toolkit@logiceditor.com for a price quote.

Database Management

Database Management — Datalog

Datalog is a deductive database system for memory constrained devices that can be manipulated with Lua.

Database Management — MySQL Proxy

MySQL Proxy

MySQL Proxy is a lightweight binary application standing between one or more MySQL clients and a server. The clients connect to the Proxy with the usual credentials, instead of connecting to the server. The Proxy acts as man-in-the-middle between client and server. The Proxy ships with an embedded Lua interpreter.

Using Lua, you can define what to do with a query or a result set before the Proxy passes them along. The power of the Proxy is all in its flexibility, as allowed by the Lua engine. You can intercept the query before it goes to the server, and do everything conceivable with it, like pass it along unchanged, fix spelling mistakes, rewrite the query, etc.‌

Database Management — MySQL Workbench

MySQL Workbench

MySQL Workbench is a visual database design tool that integrates SQL development, administration, database design, creation and maintenance into a single integrated development environment for theMySQL database system.

Database Management — PL/Lua (PostgreSQL)

PL/Lua is an implementation of Lua as a loadable procedural language for PostgreSQL: with PL/Lua. You can use PostgreSQL functions and triggers written in the Lua programming language.

Procedural languages offer many extra capabilities to PostgreSQL, similar to C language extensions: control structures, more complex computations than allowed by SQL, access to user-defined types and database functions and operators, and restriction to trusted execution.

PL/Lua brings the power and simplicity of Lua to PostgreSQL, including: small memory footprint, simple syntax, lexical scoping, functions as first-class values, and coroutines for non-preemptive threading.

File Managers

File Managers — Far Manager

Far Manager

Far Manager is a program for managing files and archives on Windows operating systems. Far Manager can be extended with Lua in two ways: in macros and as plugins.

Macros are the most common use of Lua with Far Manager. Starting from 30 Sept. 2012, Lua is used as a macro language instead of a primitive custom language that was used in earlier versions of Far. A "macro" in Far Manager is a user-written code that is executed whenever some event occurs (e.g. a key pressed, an editor opened/closed/saved, dialog opened/closed, etc.‌).

Far Manager plugins are written in C/C++/Pascal but "macros" are written in Lua.

Lua was honored with the 2011 Game Developer Magazine Front Line Award in the programming tool category.

Programming tool: Lua
By Roberto Ierusalimschy, Luiz Henrique de Figueiredo, and Waldemar Celes

Lua has become an extremely popular programming language, so much so that it's achieved a critical mass of developers in the game industry, meaning Lua skills are transferable from company to company. That's partly due to its speed and the ease with which developers can embed Lua into a game engine. Lua is also highly extensible -- it's simple to expand its functionality with libraries either written in Lua, or as extensions in other languages. And it's relatively small and simple, both in terms of the source files, and the resultant code and run-time memory usage.

Heroes of Might and Magic V.
Ubisoft/Nival Interactive
Heroes of Might and Magic V (HoMM5) is the fifth installment of the Heroes of Might and Magic computer game series. Lua is used for custom logics programming. The regular game process is programmed in C++, but all the high level functions (as hero movement, spell casting, changing resources or creatures quantity, placing map objects, creating text boxes, etc.) are also accessible from Lua script. Nival Interactive map and game designers use Lua for their needs because the language is simple to study and easy to use by non-programmers. And the programmers like Lua, because it can be easily bound to the existing C++ code and it's powerfull enough for a wide variety of applications.

Publique started in 1998 and has been developed by a team of 3 to 7 programmers during its lifetime. The production team totals 30.

Publique uses a modified version of [CGILua] as its current web engine and consists in almost 50K lines of Lua and 5K line of C (not including CGILua itself).

Lua has been chosen for its ease of prototyping, speed of execution and extensibility. It is used for almost every feature in the system other than the OS Platform, DBMS and Web Server abstraction layers. Contact: [André Carregal]

Internet CMS — Sputnik

Sputnik, An Extensible Wiki Engine in Lua.

Sputnik is a content management system designed for extensibility. It works as a wiki out of the box, but can be extended into other things.

Out of the box Sputnik behaves like an easy to use and full-featured wiki that can be used "as is". It offers editable nodes, history and diff, user accounts with optional email validation, a flexible permission system, RSS feeds, etc.‌

However, Sputnik was designed to be extended. It offers many options out of the box, and it is easy to add more. You can surely change the way Sputnik looks — see some of the examples in Sightings. But you can also do much more.

Sputnik can also be used as a platform for a wide range of "social software" applications. A few extra templates and perhaps a few lines of Lua code can turn it into a bug tracker, a photo album, a blog, a calendar, a mailing list viewer, or almost anything else. So, you can think of it as a content-management system or a web platform of sorts.


Internet Email — FreePOPS

FreePOPs, an extensible mail proxy, uses Lua to power its web front-end.

Internet Email — MailCatch (Anti-spam)

MailCatch Service

MailCatch is an email service that allows you to create temporary disposable mailboxes, in a completly anonymous way. When you are asked for an email address by a website and you do not want to give yours (for fear of spam), you can simply give whatever mailbox name you want on the mailcatch.com domain (like whatever@mailcatch.com). Then go to the MailCatch web site, type in the mailbox name and check your mail. You can access your mailbox even faster by using a URL like yourinbox.mailcatch.com

The site is based on many Lua Kepler Project modules (and it runs an xavante, although behind an apache proxy). The pages are rendered using a custom mod of
the Cosmo template library.

Internet Email — spamfilter.lua


spamfilter.lua is an anti-spam filter written in Lua using the OSBF-lua module. It takes special advantage of EDDC to introduce TONE-HR, a highly effective training method. The combination of OSB, EDDC and TONE-HR to enhance a classical Bayesian classifier resulted in the best spam filtering performance in TREC's Spam Track 2006 and in CEAS 2008 Live Challenge.

OSBF-Lua (Orthogonal Sparse Bigrams with confidence Factor) is a Lua C module for text classification. It is a port of the OSBF classifier implemented in the CRM114 project. This implementation attempts to put focus on the classification task itself by using Lua as the scripting language, a powerful yet light-weight and fast language, which makes it easier to build and test more elaborated filters and training methods.

The OSBF algorithm is a typical Bayesian classifier but enhanced with two techniques originally developed for the CRM114 project: Orthogonal Sparse Bigrams - OSB, for feature extraction, and Exponential Differential Document Count - EDDC (a.k.a Confidence Factor), for automatic feature selection. Combined, these two techniques produce a highly accurate classifier. OSBF was developed focused on two classes, SPAM and NON-SPAM, so the performance for more than two classes may not be the same.

Internet Email — LuMail


Lumail is a modern console-based email client developed for GNU/Linux.

There are many graphical clients for email, but comparatively few designed solely for console use. With the exception of GNU Emacs none of the console clients I examined had any built in support for scripting with a real language.

Lumail is scripted and configured in 100% Lua, along with many lumail-specific functions. Lumail can be extended using Lua and Lumail primitives.

Network Diagnostics

It won Linux Journal's Editor's Choice Award for Best Security Tool, LinuxQuestions.Org Security App of the Year award, and Info World's Best Information Security Product award. The Nmap scripting language is an embedded Lua interpreter which was extended with libraries for interfacing with Nmap. Lua was chosen because it exceeded in all criteria for Nmap: it is small, distributed under the MIT license, has coroutines which provide a sane method for parallel script execution, was designed with embeddability in mind, has excellent documentation, and has a large and committed community. http://nmap.org/

Internet Network Diagnostics — Wireshark

Graphical User Interfaces

Internet UIs — OpenWrt LuCI Web GUI

OpenWrt LuCI web GUI.

LuCI was founded in March 2008 as "FFLuCI" as part of the efforts to create a port of the Freifunk-Firmware from OpenWrt Whiterussian to Kamikaze.

The initial reason for this project was the absence of a free, clean, extensible and easily maintainable web user interface for embedded devices. While most similar configuration interfaces make heavy use of the Shell-scripting language LuCI uses the Lua programming language and splits up the interface into logical parts like models and views, uses object-oriented libraries and templating. That ensures a higher performance, smaller installation size, faster runtimes and what is even more important: better maintainability.

Meanwhile LuCI evolved from a MVC-Webframework to a collection of several libraries, applications and user interfaces with general purpose for Lua programmers while the focus still remains on the web user interface which also became an official part of OpenWrt Kamikaze.

Web Browsers

Internet Web Browsers — Firefox Web Browser

The Firefox Web browser can be extended using Lua and Moonshine, an embedded Lua environment for Firefox.

Internet Web Browsers — LuaKit

Malware — sKyWIper, Flame, Flamer

sKyWIper, Flame, Flamer (PDF)

The sophisticated cyber-spy malware sKyWIper (also known as Flame and FLamer) embeds Lua and includes over 3,000 lines of Lua code. "Many parts of Flame have high order logic written in Lua — with effective attack subroutines and libraries compiled from C++," according to Kapersky Labs.

sKyWIper has very advanced functionality to steal information and to propagate. Multiple exploits and propagation methods can be freely configured by the attackers. Information gathering from a large network of infected computers was never crafted as carefully as in sKyWIper. The malware is most likely capable to use all of the computers’ functionalities for its goals. It covers all major possibilities to gather intelligence, including keyboard, screen, microphone, storage devices, network, wifi, Bluetooth, USB and system processes.

The results of our technical analysis support the hypotheses that sKyWIper was developed by a government agency of a nation state with significant budget and effort, and it may be related to cyber warfare activities.

sKyWIper is certainly the most sophisticated malware we encountered during our practice; arguably, it is the most complex malware ever found.

Digital Fusion

eyeon Software

Digital Fusion is a fully integrated, non-linear compositing and special effects post-production system for finishing, design and effects creation, used extensively in many feature films, HDTV productions, broadcast video, web-based/multimedia projects and more.

Lua forms the basis of 'DFScript', an integrated scripting language added in Digital Fusion v4. This allows the automation of repetitive tasks within the program, as well as facilitating integration into other aspects of a post production facility, such as clip management, 3D renderer integration, EDL/conform integration etc.‌

In addition to scripting being used for pipeline integration, render management and things like slate generation etc, it is also possible to write image processing plugins ("Fuses") using Lua.

Lua scripting to Fusion can also be done via network, to automate processes across render farms or multiple workstations.

Multimedia — Giggle

The Moving Picture Company
Giggle is a renderman procedural DSO developed for the production of visual effects created for the film 'Troy'. This project required the rendering of scenes comprising tens of thousands of battling soldiers,in addition to complex city layouts and particle effects for flames, smoke and dust. The generation of all this geometry was handled almost exclusively at rendertime by Giggle.

Giggle's core functionality comprises approximately 40,000 lines of C++, written by 2 MPC programmers over the course of 9 months. This provides many capabilities including : * loading of geometry, shaders, particle caches and a proprietary cache format for agent simulations. * skinning and other geometry modifiers * procedural geometry generation * kd tree classes for space partitioning * geometry evaluators to perform ray intersections and closest point queries.

The functionality is bound into Lua, providing a flexible scripting interface which allows it to be easily adapted to specific tasks. MPC initially chose Lua for its reputation for speed and efficiency as well as for the great simplicity of its API. It has subsequently proved itself through heavy use by a team of 16 or so CG artists and across a render farm of over 500 machines.Since adoption, Giggle's use has been extended to other MPC feature pipelines, and coupled with an interactive interpreter and OpenGL preview renderer to provide interactive script development and debugging.

Scripting Layer for Android (SL4A).  (SL4A) brings scripting languages to Android by allowing you to edit and execute scripts and interactive interpreters directly on the Android device. These scripts have access to many of the APIs available to full-fledged Android applications, but with a greatly simplified interface that makes it easy to get things done.

Scripts can be run interactively in a terminal, in the background, or via Locale. Lua, Python, Perl, JRuby, BeanShell, JavaScript, Tcl, and shell are currently supported, and we're planning to add more

Operating Systems & Window Managers — Awesome Window Manager

Operating Systems & Window Managers — Damn Small Linux

Damn Small Linux uses Lua to provide desktop-friendly interfaces for command-line utilities without sacrificing lots of disk space.

Operating Systems & Window Managers — Hydra


Hack your OS X desktop environment.

Hydra is a lightweight window manager with a powerful API and an extremely small footprint.

Written in a small bit of Objective C but mostly in Lua. Extensible and configurable with Lua. Licensed under the same license as Lua.

Design Principles

First and foremost, Hydra must be stable. It should never crash. You should only ever have to launch it once, and it should stay running until you quit it (or your computer restarts). No exceptions to this.

Secondly, Hydra must be lightweight. It should never do anything that drains your computer's battery. It should never poll for anything. And it should practically never use more than 10 MB of memory. Everything it does should feel instant and snappy, never sluggish or delayed.

Thirdly, its API should be completely transparent. There should be no surprises in how it's behaving, or what's being executed and when. It should be fully predictable.

Finally, the API must not be bloated. Nothing should be added that is impossible or impractical to do in pure Lua; what should be included is what's extremely common and likely to be used in everyone's configs.

Operating Systems & Window Managers — Ion Window Manager

Ion is a tiling and tabbing window manager for the X Window System. It is designed such that it is possible to manage windows using only a keyboard, without needing a mouse. Ion has been scriptable with Lua since version 2.

Ion is no longer actively maintained but its fork, Notion, continues to be actively developed.

Operating Systems & Window Managers — Lua OS

Lua OS is—or aspires to become—two things:

  • A first-class modern Linux distribution for the desktop that you can use every day for everything you want to do with your computer—and something that is always offering enjoyment.
  • A next-generation, orthogonally persistent operating system for portable, manageable and secure scripting code.

Operating Systems & Window Managers — MikroTik RouterOS

MikroTik RouterOS has beta support of Lua in 4.x, and planned support in 5.x. See http://wiki.mikrotik.com/wiki/Lua.

Operating Systems & Window Managers — Notion

Notion can be configured and extended using Lua (PDF).

Operating Systems & Window Managers — Open AT OS

Open AT OS is an operating system provided by Sierra Wireless together with its wireless modules. It natively provides GSM related functions, such as GSM voice calls or data transfer related APIs, in addition to standard operating system functions. The firmware enables user applications to be written in Lua.

Operating Systems & Window Managers — OpenWrt

OpenWrt is described as a Linux distribution for embedded devices.

Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developer, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

The web extension interface of OpenWrt can be further extended using Lua.

Pattern Recognition

Pattern Recognition — APRIL-ANN

APRIL-ANN toolkit (A Pattern Recognizer In Lua with ANNs). This toolkit is implemented by using an in-house package system and Lua binding tool for C++. It incorporates ANN algorithms (as dropout, stacked denoising auto-encoders, convolutional NNs), with other pattern recognition methods as HMMs among others. Gradient based optimization with backpropagation, Conjugate Gradient, Quickprop, RProp is possible. A package for automatic differentiation is being developed, which combined with gradient based optimization algorithms makes feasible learning of any differentiable statistical model. It is projected in one year to integrate decoding algorithms for speech, handwritten text and machine translation. Contributions are wellcome, the toolkit is in active development and a lot of work needs to be done.

Physical Simulators

Physical Simulators — Techne

Techne is a general purpose, programmable, interactive, physical simulator and renderer. It reads in a set of scripts wherein every aspect of a physical system is specified and then proceeds to simulate and render the system in real-time. This is the general idea. The main goal is to decouple computer programming, in its involved low-level form at least, from digital art creation, shifting effort away from worrying about graphics library quirks and memory allocation and towards understanding and modeling the physical and aesthetic aspects of a given system.

Plain Text Editors

Plain Text Editors — CodeMAX

is a simple and fast text editor with the possibility to add custom features using the script language Lua. By creating plugins with Lua you can customize CodeMAX on your own. For exsample it is possible to build a complete IDE for different programming languages like C/C++, PHP, Pascal or Basic. http://codemax.luaforge.net/

Plain Text Editors — Estrela Editor

Estrela Editor is our wxLua-based editor primarly serving as Luxinia IDE, of course it can be used for any Lua coding. It has code completion, api tooltips and is (open-source/free).

Plain Text Editors — FXiTe

FXiTe is an advanced cross-platform text editor. It features built-in syntax highlighting for 40+ languages, an embedded Lua scripting engine, macro recording and playback, multi-line regular expression search and replace, rudimentary ctags and calltip support, a flexible interface to external tools, and a built-in "message window" to capture the output of external commands such as compiler error messages, etc. FXiTe is built using the Fox GUI toolkit and the FXScintilla text widget.


Plain Text Editors — Gnu Zile

GNU Zile (short for "Zile Implements Lua Editors") is a lightweight Emacs subset. Zile has all of Emacs's basic editing features: it is 8-bit clean (though it currently lacks Unicode support), and the number of editing buffers and windows is only limited by available memory and screen space respectively. Registers, minibuffer completion and auto-fill are available. Function and variable names are identical with those of Emacs.

Zile has been translated from C to Lua in order to make it easier to maintain in future and is in the final stages of preparation for alpha release. There's plenty of scope both to improve the code (currently, not very "Lua-ish") and reduce its 6,500 lines considerably. Note that as of this writing, Zile does not yet support Unicode.

Zile is currently being rewritten as an editor toolkit ("Zile Implements Lua Editors"), and will support a range of editors, including Zmacs (an Emacs subset) and Zi.

Plain Text Editors — lua-ed

lua-ed is a clone of the Unix standard editor "ed", written in Lua.

Plain Text Editors — LucED

LucED, the Lucid Editor, is an open source text editor with a graphical X11 user interface. Although the program is in its early development stage, you are welcome to test the current development snapshot.

The principal aim of the LucED project is to develop a text editor with the following features:

  • A simple and minimalistic, but powerful user interface that is similar to the NEdit text editor, but does not depend on Motif
  • Embedded Lua programming language for scripting and configuration
  • Powerful regular expressions using the PCRE library
  • Syntax highlighting configurable via regular expressions, similar to the NEdit syntax highlighting but with the enhancement to use arbitrarily nested patterns
  • Fast and responsive user interface: e.g. syntax highlighting is done in the background and does not freeze the user interface, special handling to achieve fast keyboard repeat rates
  • No dependencies on high-level widget toolkits in order to minimise the requirements for the operating system

Plain Text Editors — SciTE

SciTE is a SCIntilla based Text Editor. Originally built to demonstrate Scintilla, it has grown to be a generally useful editor with facilities for building and running programs. It is best used for jobs with simple configurations. SciTE features a lot of modern editor features (most provided by Scintilla) like syntax highlighting of code, call tips, autocompletion of code, folding, etc. Since version 1.60, Lua can be used to perform operations on the current buffer, using the full API of the Scintilla component.

Plain Text Editors — Textadept


"In a world where code bloat is commonplace and application speed is second to its number of features, Textadept breaks that trend, aiming to stay minimalist and fast, but at the same time being ridiculously extensible. At its core lies less than 2000 lines of C code, and that is how it always will be. While other editors rely on numerous plugins for a wide range of functionality, recordable macros to speed up workflow, and shell scripts to quickly transform text, Textadept takes it to the extreme: it gives you complete control over the entire application using the embedded Lua language. Lua is one of the fastest scripting languages available and has a very small footprint. In fact, most of Textadept is written in Lua. The application's incredibly fast startup time and operation attest to Lua's worthiness."

Plain Text Editors — Vim

The Vim text editor is scriptable with Lua beginning with version 7.3. See http://vimdoc.sourceforge.net/htmldoc/if_lua.html.

Plain Text Editors — Zeus

Zeus programmer's editor.

Project Management

Project Management — Karm


Karm is a easy to use multi-platform task management system written in wxLua which can be used from a simple to do list to a highly complicated project management system with lots of activities. Open source, licensed under the MIT license.

  • Using Lua provides advantages and Karm provides full support to write your own scripts or Macros to customize Karm and its behavior the way you want
  • It is very easy to use, and can be made easier by adding custom commands in the Menu structure
  • It brings a refreshing change from all proprietory task management systems and those open source systems that do not do it the way you want
  • The more you use it and customize it the more it becomes like your personal assistant that makes your life more organized and stress free
  • It is designed keeping in mind use for Distributed Task Management where tasks can be distributed to people who are responsible for it and their updates are synced to the main repository and status updates are seen immediately.

Rich Text Editors

Rich Text Editors — NoteCase Pro

NoteCase Pro is a GTK+-based multi-platform outliner supporting both desktop and mobile device systems that also has versatile relational database-like capabilities for display and processing of arbitrary node groups on the basis of supported or custom node or document properties.

Robotics — Crazy Ivan Robot

Crazy Ivan Robot

Crazy Ivan Robot Team

Crazy Ivan was the robot that won the RoboCup 2000 in Denmark. Crazy Ivan has a "brain" that uses Lua for scripting language. All AI and logic is done in Lua. The brain is running on a Motorola Coldfire 5206e processor, and Lua is modified to use only int's as the Coldfire has no FPU. Contact: [Erik Hougaard]

Robotics — pbLua for the LEGO Mindstorms

pbLua for the LEGO Mindstorms

NXT Hempel Design Group

pbLua is an implementation of Lua 5.1 for the LEGO Mindstorms NXT. It is based on the open-source code for the NXT brick provided by LEGO. The low level drivers were modified slightly and then integrated with the Lua sources. pbLua is an alternative text-based programming environment for the NXT that supports coroutines, strings, tables, and limited floating point operations. The NXT is based on the ARM7 micro with 256K of FLASH and 64K of RAM. pbLua looks like a serial port to a PC and connects via USB. It is completely self contained as it runs the parser right on the brick. Eventually, we'll support the Mac and Linux platforms when we figure out how USB gets enumerated on those platforms.

Robotics — V-REP

V-REP (Virtual Robot Experimentation Platform) is a 3D robot simulator based on a distributed control architecture: Lua scripts (i.e. control programs) can be directly attached to scene objects and run simultaneously in a threaded or non-threaded fashion. This makes V-REP very versatile and ideal for multi-robot applications, and allows users to model robotic systems in a similar fashion as in reality - where control is most of the time also distributed.


Typesetting — LuaTeX

LuaTeX is an extended version of pdfTeX using Lua as an embedded scripting language. The LuaTeX project's main objective is to provide an open and configurable variant of TeX while at the same time offering downward compatibility. The criteria for choosing Lua was that it was freely available, portable, easy to extend with pdfTeX-specific functionality, small footprint, and also fun to work with.


Utilities — UltraDefrag


UltraDefrag is a disk defragmenter for Windows, which supports defragmentation of locked system files by running during the boot process. It is easy to use without any complicated scripting or a huge load of configuration settings. You can filter the files processed by size, number of fragments, file name and path. You can terminate the process early by specifying an execution time limit.

  • Boot Time Defragmentation for system file processing
  • Console interface for batch processing or setting up scheduled tasks
  • Graphical user interface to follow the process visually
  • Process single files, folders or drives from the Explorer context menu
  • Specialized processing algorithms for each situation
  • Available for both 32bit and 64bit Windows
  • Optional dryrun to get a preview of the resulting disk usage

UltraDefrag uses Lua primarily for interpretation of configuration files and for reading internationalization strings from the 'i18n' subdirectory. Lua is also used to upgrade configuration files, to convert text files from one format to another for reports, and to generate makefiles for the selected build environment and then building the program.

One commenter mentioned that Lua is used heavily in the Squeezebox system (embedded Linux for Logitech networked multimedia appliances, formerly known as Jive). I did a bit of googling and indeed, Lua is deeply integrated in Squeezebox from the OS kernel to user interfaces and user-created applet plugins, see e.g., <http://wiki.slimdevices.com/index.php/SqueezeOS_Architecture#LUA>.

But Logitech recently discontinued use and development of Squeeze OS for all but one internet "radio" product, although they've committed to continue support for Squeeze and existing appliances. <http://reviews.cnet.com/8301-33199_7-57519226-221/logitech-leaves-squeezebox-fans-wondering-whats-next/>.

The successor system is called "ue". I haven't found the mother lode of Lua documentation for it yet, but the user forums suggest that Lua 5.1 is heavily involved there too. See <http://forums.logitech.com/t5/forums/searchpage/tab/message?filter=labels&q=lua+#message-list> (user forum search for "lua " produces 89 pages of hits).
