What I did

Today felt a little like laundry-day:

I reviewed and accepted a pull-request by kingoflolz that made a low-level thing more idiomatic for Rust.

I separated some of the engine code into smaller pieces, which will make it easier to document, test and benchmark each of them

I adopted rustfmt, a style-linter for Rust (basically an automated grammar nazi) and applied it to the whole Citybound codebase

• It destroyed my beautiful hand-crafted and definitely not sloppy formatting
• It applied consistent and nice formatting in most places
• It made the uglyness of some particularly ugly code shine much more brightly
• It forced me to fix lots of formatting by hand which it was smart enough to complain about but too stupid to fix itself
• This all might seem like a detail, but actually helps a lot to achieve consistent code style when a lot of people (or just one very inconsistent person) work together

I hooked up continous integration (Travis)

• This allows me to automatically run tasks and checks when someone publishes code changes
• Right now I'm only using it to enforce the new code-style
• But: this will also be used to automatically compile and bundle the game for Windows/Mac/Linux, making publishing of new releases much easier!
• Once there are tests, those can also be run automatically when the code changes.

I wrote a more thorough guide about how to get completely setup for contributing - I'm planning to flesh this out more and more to make it easy to get started
