### Goals for 2022

Philbert:

- Macro expansion
- Cfg expansion
- Imports (use declarations)
- Visibility modifiers
- Const generics
- Bugs

Once we get though the macros milestone we should be moving onto trying to compile libcore as a new goal testcase to find more bugs.

### Goal Testcase

https://github.com/Rust-GCC/gccrs/issues/682

We are missing support for Slices and Ranges, many bugs have been found by testing this so far.

## What are we working on

Philbert:

- GSoC 2022 wiki updates
- Const folding
- see https://github.com/Rust-GCC/gccrs/pull/870
- cpp constexpr -O0 https://godbolt.org/z/rjMYGhrMd
- Method resolution
- Needs to support calling into deref operator overloads
- Planning Macros milestone
- Rustc has its own parser for macro's I am hoping we could reuse our existing parser
- The token stream contains spacing information aparently
- Need to plan out tickets
- Testing could be done by comparing AST Dumps vs the expanded rustc

Marc P:
- HIR refactoring https://github.com/Rust-GCC/gccrs/issues/825 . But currently not moving much (sorry).
## Get Involved

Not all development needs to be PR's we acively are seeking testers to raise issues. You can easily test our compiler via:

- Compiler Explorer: https://godbolt.org/z/Whq8YM7EP
- Docker: https://hub.docker.com/r/philberty/gccrs

We have a list of good first issues which contain a guide and extra information. Please feel free to join our Zulip/irc/mailing-list to ask for more guidence/mentorship on any issue.

- Good first issues: https://github.com/Rust-GCC/gccrs/issues?q=is%3Aissue+is%3Aopen+label%3Agood-first-pr
