Exercise downloader

Exercise downloader for https://rustplatform.com/

Quickstart

• install the exercise downloader, open a terminal and run:

  cargo install pybites-rust-download

• cd to the directory where you want to save the exercises
• run the downloader (free exercises only):

  pybites-rust-download

• to download all exercises (requires premium), set your API key:

  PYBITES_API_KEY=your-api-key-here pybites-rust-download

  Or export it in your shell profile so you don't have to pass it every time:

  export PYBITES_API_KEY=your-api-key-here

  You can find your API key on your profile page.

Navigating exercises

Once downloaded, use fzf to quickly jump between exercise directories:

cdf() {
  local dir
  dir=$(find . -type d | fzf --reverse --prompt='cd to> ') || return
  cd "$dir"
}

Add this to your shell profile, then type cdf to fuzzy-search and cd into any exercise.

Compile it manually

Maybe you want to have a look at the code and make some changes.

• clone the repo and cd to the main directory of the project

• cd back to the project main directory

  cd ..

• run the downloader from the project main directory

  ./exercise_downloader/target/release/pybites-rust-download
