RFPL: Recursive Functional Programming Language

RFPL is a recursive functional programming language designed primarily for educational purposes. It introduces the concept of primitive recursion—which you can read about on Wikipedia—and can also be used for non-educational purposes, such as for fun or challenges.

Usage

Installation

Easy Way

Install ANTLR4. Clone the repository and use make to run RFPL:

$ git clone https://github.com/AMBandariM/RFPL
$ cd RFPL
$ make          # Launch RFPL's interactive console
$ make journey  # Start "The RFPL Journey"

Easier Way

Alternatively, you can install RFPL using pip:

$ pip install rfpl

Then run:

$ rfpl      # Launch RFPL's interactive console
$ journey   # Start "The RFPL Journey"
$ # or run with `python -m rfpl` and `python -m journey` if there was PATH errors.

VSCode Syntax Highlighter

To enable syntax highlighting for RFPL files in VSCode:

1. Open the Extensions panel.
2. Search for RFPL.
3. Install the RFPL Syntax Highlighter extension, which provides highlighting for .rfpl files.

Development and Contribution

Translating "The RFPL Journey"

You are welcome to translate the file ./journey/journey_en.json into your native language. Submit your translation, if the translation meets our quality standards, we will include it in future releases with your name and contact information.

Future Development

Although Version 1 of RFPL is complete and published, we have plans for future improvements:

• Refactoring: Extracting 'fundamental' functions from the interpreter.
• User Experience: Implementing a robust cache and function-guessing system.
• Dependency Management: Potentially removing ANTLR and other nonessential dependencies.

Documentation

You have to experience the language and read the source code. There is no additional documentation at this time—sorry about that.
