asm.ts

Parses a TypeScript dialect and compiles to native code via generating assembly code via ts.asm (TSASM).

Motivation

Learning to design a native programming language, compiling to assembly code, and having fun doing so! Your PR's are welcome here! :)

I'd like to use this language to build AOS, a new operating system for the x86_64 architecture that is completely built using web technology, in-browser.

Status

Early research phase. Looking into the best way how to write the tokenizer, lexer and parser. AssemblyScript dialect variant looks most promising. Probably fork the AssemblyScript parser and AST codebase, remove anything OOP and go with a limited feature-set, then adapt.

A C-like feature set would be very desirable. I don't see much value in implementing OOP features here. Dynamic memory allocation and GC via assembly is a big deal that I'd like to postpone for a later version.

POC (Proof of Concept) using ANTLR4

TypeScript dialect grammar / parser implemented via ANTLR4: https://github.com/tunnelvisionlabs/antlr4ts

See: poc.ts, grammar, src/lexer and src/parser Run: yarn test

POC (Proof of Concept) using AssemblyScript

Using the parser of AssemblyScript (comes with native types out of the box): https://github.com/AssemblyScript/assemblyscript/blob/main/src/parser.ts

See: src/as and poc-as.ts Run: yarn test-as
