Advent of Code in Go

This is set up as a Visual Studio Code devcontainer, to make it easy to set up the Go environment.

Use

1. Clone repo
2. Open in Visual Studio code
3. Allow it to establish a 'Dev Container' using the Dev Container extension (which you'll be prompted to install if not already present)
4. It'll take a few minutes to create the container.
5. Bring up a terminal in the container (Terminal->New Container)
6. Run go run test.go
7. You should see a message confirming that your Go container is working

Working on Advent of Code challenges

Setup

1. Log into Advent of Code in a browser and extract the session cookie.
2. Place it in the .env file, based on .env.sample.

To solve a new day

• Inside the dev container, run ./setup-day.sh <year> <day>
  • This will fetch the assignment details and input, into <year>/<day> and set up a basic Go skeleton for the day
• To run the code for a part for a day:
  • cd <year>/<day>
  • make <part> (e.g. make 1)

To run all days for a year, checking correctness and performance

• ./test-all.sh <year>
