LiveCode, originally known as Revolution, is a unique cross-platform development environment that has garnered attention for its simplicity, flexibility, and rapid application development (RAD) capabilities. The environment, alongside its scripting language, Transcript, allows developers to create applications for multiple platforms, including mobile, desktop, and web. Initially inspired by the HyperCard system, LiveCode has gone through numerous transformations, from its inception in the early 2000s to its open-source rebirth in 2013. This article explores the history, evolution, features, and impact of LiveCode in the landscape of modern software development.

Origins: The Birth of Revolution

The story of LiveCode dates back to 1993, when Mark Waddingham, a British software developer, first conceptualized the language that would later evolve into Revolution. Initially known as MetaCard, this early programming environment drew heavy inspiration from Apple’s HyperCard. HyperCard, introduced in 1987, was revolutionary in its time for offering a graphical user interface (GUI) for programming that was accessible to non-programmers. MetaCard attempted to extend this idea, aiming to provide a flexible and extensible platform for developers.

MetaCard’s technology was based on the idea of stacks—self-contained units of programming that could hold both code and assets like images or sounds. This approach provided a visual and interactive method of developing applications. However, despite its promising features, MetaCard was not widely adopted. In 2003, Runtime Revolution, a company founded by Waddingham, acquired MetaCard’s engine technology, which formed the foundation for what would eventually become Revolution.

Revolution was officially released in 2001, and it was heralded as a modern implementation of the MetaCard concept, with a focus on rapid application development and cross-platform compatibility. One of its defining features was the Transcript programming language, a dynamic scripting language that resembled HyperTalk, the language of HyperCard. This allowed users to create applications with minimal effort, using a readable, English-like syntax.

The Transition to LiveCode

In 2010, Revolution underwent a significant rebranding and transformation, emerging as LiveCode. This change was part of a larger shift within the company, which aimed to clarify the relationship between the product and the company itself. Runtime Revolution was rebranded as LiveCode Ltd., aligning the company’s name with its flagship product. The rebranding also marked a new chapter in LiveCode’s development, with the introduction of new features and an emphasis on modern development practices.

In 2013, LiveCode made a major leap by releasing a free and open-source version of the software—LiveCode Community Edition. This version was made available after a highly successful crowdfunding campaign on Kickstarter, which raised nearly $400,000 to fund the transition. By making the software open-source, LiveCode invited a broader community of developers to contribute to its evolution, helping the platform grow in both functionality and adoption.

Key Features of LiveCode

The platform also supports Raspberry Pi, making it an attractive option for IoT and embedded systems. This cross-platform capability allows developers to write code once and deploy it across a range of devices, minimizing the need for platform-specific adjustments.

  2. The Transcript Language: At the heart of LiveCode is its scripting language, Transcript. Designed to be easy to read and understand, Transcript allows developers to write code that closely resembles natural English, reducing the barrier to entry for newcomers. The language belongs to the xTalk family, which also includes HyperTalk, making it particularly appealing to those familiar with these environments.

  3. Integrated Development Environment (IDE): LiveCode comes with an integrated development environment that allows users to design and code within a unified interface. The IDE supports drag-and-drop functionality for creating user interfaces, as well as a built-in debugger and real-time feedback, streamlining the development process. Developers can also test their applications directly within the IDE, which reduces development time.

  4. Object-Oriented Features: In recent years, LiveCode has adopted more modern programming paradigms, including object-oriented programming (OOP). This shift culminated in the introduction of LiveCode Builder in version 8, a new language designed specifically for creating custom widgets and extending the capabilities of the LiveCode environment. LiveCode Builder provides developers with the ability to define new object classes and incorporate them seamlessly into their applications, representing a departure from the more rigid xTalk model of earlier versions.

  5. Web and Mobile Development: LiveCode has long been able to target desktop applications, but its capabilities expanded significantly with the inclusion of mobile and web support.
