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 -r --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 -r --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!

VSCode extension & language server

In order to have syntax highlighting and language server features, you will need to install the Cairo Language Server. The instructions available in the Cairo repository

Testing

For Cairo related tests

cargo test cairo

For all tests

cargo test

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.

Adding new exercises

Here's what an exercise looks like,

An exercise is pretty much a single well commented Cairo file.
Exercises are organised into modules and are placed in ./exercises/<module_name>/<exercise_name>.cairo
Exercise accompanies some metadata describing it in ./info.toml
When introducing a concept for the first time, try to start minimally.
Subsequent exercises for the same concept can grow in complexity.

Contributing with a new exercise

Add the exercise file in the ./exercises directory.

Insert information about the exercise in ./info.toml file. For example

[[exercises]]
name = "new_exercise"
path = "exercises/new_module/new_exercise.cairo"
mode = "test"
hint = """
Try the Harlem shake
"""

Run your exercise with starklings run as you write

cargo run -r --bin starklings run new_exercise

Check that the tests pass.
Send your PR!

Updating Rust logic/Cairo version

Test your changes.
Make sure you have solutions to all the exercises in ./solutions directory.
Run cargo run -r --bin starklings compile_solutions to confirm all exercise solutions still compile.
Make your pull request.
