Thanks for installing starklings!

Is this your first time? Don't worry, starklings is made for beginners! We are
going to teach you a bunch of stuff about StarkNet and Cairo.

Here's how starklings works,

1. To start starklings run `cargo run --bin starklings watch`
2. It'll automatically start with the first exercise. Don't get confused by
error message popping up as soon as you run starklings! This is part of the
exercise that you're supposed to solve, so open the exercise file in an editor
and start your detective work!
3. If you're stuck on an exercise, there is a helpful hint you can view by
typing `hint` (in watch mode), or running `cargo run --bin starklings hint
exercise_name`.
4. When you have solved the exercise successfully, Remove `// I AM NOT DONE`
comment to move on to the next exercise.
5. If an exercise doesn't make sense to you, please open an issue on GitHub!
(https://github.com/shramee/starklings-cairo1/issues/new).

Got all that? Great! To get started, run `starklings watch` in order to get the
first exercise. Make sure to have your editor open!

Contributing

Thanks for your interest in the project. You can fork the repo, create a branch with a descriptive name (maybe the issue number and a word or two to describe it) and submit a pull request to the dev branch of this repo.

Branches

We have 2 active branches,

1. dev This is where new development happens. All pull requests should be made to this branch.
2. main This is for cloning and running starklings. dev is merged into main after a second set of testing.

Adding new exercises

1. New exercises can be added in ./exercises directory.
2. Insert information about the exercise in ./info.toml file. For example

   [[exercises]]
   name = "new_exercise"
   path = "exercises/new_module/new_exercise.cairo"
   mode = "compile" # or "test"
   hint = """"""

3. Check that the tests pass.
4. Send your PR to dev branch of the repo!

Updating Rust logic/Cairo version

1. Test your changes.
2. Make sure you have solutions to all the exercises in ./solutions directory.
3. Run cargo run --bin starklings compile_solutions to confirm all exercise solutions still compile.
4. Make a pull requests to dev branch of the repo!

Merging dev into main (maintainers)

1. Create a PR from dev branch to master branch.
2. Run all tests, and check solutions with cargo run --bin starklings compile_solutions.
3. Check to make sure no new changes were merged into dev since the PR was created.
4. If everything makes sense, merge away!
