Could you build this?
No Creating a novel programming language with its own bytecode, compiler/evaluator, and virtual machine requires formal compiler and low-level computer architecture expertise.
What it would actually take: The project requires designing a stack-based virtual machine, parser, tokenizer, and bytecode execution engine in C, Rust, or assembly inspired by ColorForth. Key challenges include word dictionary mechanics, inner/outer interpreters, minimal memory footprint design, and direct hardware/memory mapping. It demands deep understanding of Forth internals, stack machine architectures, and language runtime engineering.
Discussion
17 comments analyzed.
Competitors mentioned: Jai (Jonathan Blow's language), Neon (object-oriented Forth for Mac), Powermops (Forth variant with ARM version), Common Lisp, Scheme
Concerns raised: Steep learning curve for developers from higher-level languages, Postfix notation rejected by many programmers' mental models, Windows API breaking changes (BitBlt) made porting problematic, Lack of standardization and difficulty defining what Forth actually is, Single-threaded and no multi-process support currently
Feature requests: Multi-threading and multi-process support, Consistent case conventions in code examples, TCP/IP stack integration for modern use cases
