Introduction

Moonli is a beautiful programming language with a simple syntax and a very interactive development experience. This enables rapidly prototyping new programs. At the same time, once a prototype is ready, the programs can also be optimized for runtime performance as well as long term maintenance.

Features

• Sane variable scoping rules as given by common lisp
• Sane namespace scoping thanks to common lisp package system
• Sane restarts and condition system thanks to common lisp
• Strong typing with optional static typing, optional dynamic scoping
• Availability of optimizing compilers such as SBCL
• Sensitive to newlines and semicolons but not to spaces and tabs (indentation insensitive)
• Returning multiple values without an intermediate data structure
• Support for rapid prototyping through CLOS and image-based development

Plan

• Real numbers, strings, characters, lists, infix arithmetic operators, literal hash-tables, literal hash-sets
• Typing using "expr::type" operator
• Support for declare and declaim
• Literal syntax for vectors, array access
• BODMAS rule for parsing expressions
• Binaries
• VS Code integration
• Emacs mode and integration with slime: useable but less than ideal
• Infix Logical operators
• Add more forms: progn, mvb, dsb, more…
• Add more tests
• Reverse transpile from common lisp
• Multidimensional arrays, broadcasting, other operations: needs an array library
