The Air Programming Language

The Air programming language is carefully designed to solve programming problems once and for all.

It is an experimental proof-of-concept project and is still in the very early stages of development.

Goals

The Air language seeks to solve programming problems once and for all. It should be able to

• express any describable information, such as requirements and implementations, problems and solutions, propositions and proofs.
• provide any information about the language and the program itself.
• implement any theoretically possible information processing requirement, such as implementing requirements, answering questions, and proving propositions.
• use information about the language and the program itself to perform property proofs and performance optimizations, achieving the best properties and optimal performance.
• provides stable syntax and semantics, allowing users to learn the programming language once and for all.

Non-Goals

• No design choices are taken for granted, and language features are not copied from other languages without review.
• Suboptimal designs are not chosen to accommodate user habits.
• Solutions that only solve most but not all problems are not satisfactory.
• Impossible tasks are not attempted to be implemented.
• The language is not constantly updated to implement more requirements.

Design

• Decouple syntax from semantics, making syntax available as a general data exchange format.
• Build a concise semantic core and provide rich initial context.
• Allow functions to access context, which means that control statements are just functions that can access context.
• Implement a universal logical framework based on computability theory, replacing type systems based on type theory.
• Implement a universal problem framework based on reverse computation theory, used to express any describable requirement or problem, replacing interface/trait systems.
• Implement a universal algorithm framework based on complexity theory, attempting to achieve artificial general intelligence.
