History

LiveCode began as an expert IDE for MetaCard
MetaCard
MetaCard was a cross-platform, commercial GUI toolkit. MetaCard included an IDE and had its own language, MetaTalk. From the MetaCard Corporation website: "The MetaTalk language has all the features common to third-generation languages like C/C++/Java but has a much simpler syntax."All the Metacard...

. Both HyperCard and MetaCard utilized an English-like language that arguably was easier to learn than BASIC.

The language has been known by several names including Transcript, RevTalk and as of November 2010 "LiveCode". The entire product including the IDE is now officially referred to as LiveCode. The iOS version is available as of December 2010, with the Android and Server Versions under development.

Environment

The LiveCode environment consists of a powerful and easy to use programming language

The IDE allows building of graphical user interface

GUIs can be used in computers, hand-held devices such as MP3 players, portable media players or gaming devices, household appliances and...

 by dragging controls into a visual environment, with interactive feedback and modification of existing and custom properties through property inspectors. The LiveCode control palette includes both native application controls (edit fields, menus, buttons, operating system specific dialogs) as well as media controls such as a movie player and support for direct control over audio, text-to-speech, transparency and blend modes of all visual objects and more.

Although LiveCode generates cross-platform applications, it is still possible to add operating system specific features. For example, it is possible to utilize Quartz

Quartz specifically refers to a pair of Mac OS X technologies, each part of the Core Graphics framework: Quartz 2D and Quartz Compositor. It includes both a 2D renderer in Core Graphics and the composition engine that sends instructions to the graphics card...

 graphical features of Mac OS X, execute VB Scripts on Windows, and run UNIX shell applications.

LiveCode can support third-party media such as QuickTime (including Quicktime VR) and Flash. The development environment is used to develop software applications more quickly than traditional languages and the company has successfully grown a consultancy business designed to bring software to market in very short time periods. This is promoted under a Challenge RunRev banner where the company claims it can take on virtually any software development project and do it faster in the LiveCode language than any other programming language.

On 11 November 2009 in San Francisco, the company officially launched version 4.0 of the Revolution programming language (renamed LiveCode in November 2010), officially bringing the revTalk language to the web.

In late 2009, the company launched the RunRev Partner Program giving all people programming in the LiveCode language the opportunity to work more closely with the core LiveCode development team. This provision of dedicated Technical Account Managers is part of the continued development of the LiveCode language and is designed to make it even more accessible.
