Apologue Programming Environment app for iPhone and iPad

Apologue is a development environment for the Parable language. It provides a code editor, stack and memory displays, and embedded documentation.

Parable is a concatenative, stack-oriented language loosely related to Forth. It is reverse polish in nature, and offers a variety of useful features including support for basic data types, garbage collection, and code statistics.

Apologue requires a network connection to operate. Code is submitted and run anonymously on a Parable server, with the results being sent back to the client for display.

The Apologue environment offers:

- access to the latest Parable runtime
- code editor supporting multiple projects
- online code evaluation
- integrated documentation
- execution results
