Design and build FelixScript: a modern, concise programming language in Go

[wilkolbrzym-coder]

Overview

Create a new programming language called FelixScript with the following characteristics:

• Modern, ultra-concise, and extremely readable syntax (even more so than Python)
• Target a code density 20% higher than Python (i.e., less code for the same logic)
• Easy to learn and use; all function names are short, clear, and expressive
• Exceptionally detailed interpreter errors, with actionable suggestions and precise locations
• Designed for extensibility—allowing APIs, parsers, and advanced integration
• File extension: .fs

Core Requirements

• The language should be implemented in Go
• Modular architecture: ~30 modules, grouped into files of 5-7 modules each
• Each module should be very modern, minimalistic, and powerful, even if not all modules are used by the core language (allowing future API/extensibility)
• Syntax should be extremely readable and modern, suitable for new-generation coding paradigms
• Error messages must be millimeter-accurate and include suggestions for fixing issues
• Project structure and code should allow for easy future extension and robust API integrations

Tasks

• Design the syntax and grammar for FelixScript
• Plan and document around 30 language modules (grouped into files, 5-7 per file)
• Implement a modular interpreter in Go
• Ensure interpreter errors are extremely detailed and actionable
• Create clear documentation and examples
• Structure the project for extensibility and modern development

Notes

• This is a foundational issue for the entire project. Sub-issues can be created for module design, parser, interpreter core, error handling, documentation, etc.
• Inspiration should be drawn from Python, but with more modern, readable, and concise syntax.
• Consider the needs of future API/plugin developers when designing extensibility and error reporting.
