My participation in the Advent of Code for 2020.

Please feel free to browse through my solutions. Be warned that there may be spoilers if you haven't submitted your own answers already.

Setting up the sandbox

These instructions are probably over-complicated. docker create instead of docker run -it followed by exit should be possible.

$ docker build -t advent-of-code-2020-rust .

$ docker run -it --name advent-of-code-2020 --mount type=bind,src=$HOME/Projects/advent-of-code/2020,dst=/advent-of-code/2020 advent-of-code-2020-rust
# exit
$ docker start advent-of-code-2020
$ docker exec -it advent-of-code-2020 zsh
#

Edit/build/run/repeat

# cargo build
# cargo test
# cargo run

Optional: Connecting VS Code to the sandbox

1. Click on the whale icon in the sidebar.
2. Right-click on the running container and choose "Attach Visual Studio Code". A new VS Code window will open.
3. Click "Open Folder". Navigate to /advent-of-code/2020 then click "OK".
4. Install the rust-lang.rust extension in the container. If asked to install additional Rust components, click "Yes".
5. When done, click on "Container advent-of-code-2020" in the bottom-left corner of the window, then choose "Close Remote Connection".
