A script language like Python or Lua written in Rust, with exactly the same syntax as Go's.
- Runs most pure Go code, probably add some dynamic features if requested.
How do I try
The project "engine" is the entry/wrapper. there are test cases in here to browse through.
- Make sure your Rust installation is up to date.
- Clone this repository.
- Go to goscript/engine
cargo test -- --nocapture
- As an embedded language like Lua.
- As a glue language like Python.
- A scripting language that can be embedded in Rust.
- Go is popular and easy(even as a scripting language), why invent new grammars?
- In some cases, when your project gets big:
- If Go were an embedded language it would be better than Lua.
- If Go were a glue language it would be better than Python, in terms of project maintainability.
- I found a new hammer(Rust) that I like, and decided to use it on a nail(Go) that I like.
- There are five projects:
- parser -- a port of the official implementation that comes with the Go installer.
- type checker -- a port of the official implementation that comes with the Go installer.
- codegen -- generates the bytecode.
- vm -- runs the bytecode.
- engine -- the wrapper.
- Language: Feature complete (except the features that are so insignificant that I forgot -_-) Some of the features are, probably for the first time, implemented in a script language, like Select/Defer/Pointer/Interface/Struct.
- Standard library: just got started.
- Production readiness: far from. The parser and the type checker are probably ok because they were ported and passes the test cases comes with the original code. The backend has a lot of rough edges, and we need much more test cases.
- Next step: no new features for now, polish then work on the standard library.
