# quokka
this is my work in progress programming language targeting the [QBE backend](https://c9x.me/compile/)
as this is my first language i aim for:
- no crazy/revolutionary new features
- simple type system
- modern and clean syntax inspired by rust and go
you can find the language specification in [the `grammar` file](./grammar) or look at the current example i have comitted in [`test.qk`](./test.qk)
## roadmap
- [x] tokeniser:
- [x] various punctuation tokens
- [x] keyword/identifier tokens

- [x] char literals
- [x] string literals
- [x] boolean literals (true, false)
- [ ] parser:
- [ ] statements:
- [x] import statements
