WebBS | A toy language that compiles to WebAssembly | Binary Executable Format library

WebBS is a JavaScript library typically used in Programming Style, Binary Executable Format applications. WebBS has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

WebBS (short for "(Web)Assembly (B)etter (S)yntax") is a simple byte-twiddling language that compiles to WebAssembly bytecode. WebBS isn't intended to be particularly useful on its own - it's a toy language. Rather, it's intended to be an educational tool for learning about WebAssembly and compiler design. The WebBS code contains an extremely simple compiler, written in pure Javascript, which runs entirely on the front end. The WebBS compiler has zero external dependencies and no build or bundling steps, and the whole thing (including this GUI) is a few hundred lines of well-commented code. It has a very simple architecture and it translates WebBS code into WebAssembly bytecode in pretty much the most straightforward possible way, with (almost) no optimization or code restructuring. It's written to be very easy to understand and modify, so programmers (especially Javascript programmers) who are interested in learning more about how compilers work can dig right in by reading the source. The editor GUI allows the user to write and run simple WebBS programs, and view the compiler's output either as an abstract syntax tree or as annotated(!) WebAssembly bytecode, so interested programmers can get a sense of how WebBS expressions are parsed and translated into the stack-machine-like WebAssembly bytecode without even reading the source. If you want to write your own lightweight DSL that runs on the front end, WebBS wouldn't be a terrible place to start (and in fact, it was initially created as the first steps toward exactly that).
