bliss
bliss is (or at least will be) an elegant, dynamically typed programming language.
So far, we have a kind of broken tree-walking interpreter. It's a bit buggy, but it works generally. The plan is to turn that into a bytecode VM, but that might take a while to do.
I haven't really put together any resources for learning the language, so you can try to figure it out from the examples for now (if you're brave).
The source code is kind of all over the place so expect a refactor coming soon to a theater near you
Goals of this project
- Have error good and clear parser errors that point you in the right direction (kinda there)
- Have a powerful standard library, that makes it practical
- Have decent performance and garbage collection
Influences
- JavaScript
- Elixir
- Haskell
- Ink
- The Interpreter book
Known Bugs/issues
- For some reason non-tail recursion doesn't work. See this example
- Recursion in general is kinda broken tbh
- There is no garbage collection so the stack will overflow if you do too much recursion
- The parser can only output one error at a time
I plan to fix these eventually, so don't worry too much
