Advent README Stars

This action adds and maintains a stars report in your README based on your Advent of Code progress.

Example Table

2021 Results

Quickstart

Add this line somewhere in your README.md:

<!--- advent_readme_stars table --->

Make a note of your user ID and add your session cookie to your repo as a secret called AOC_SESSION.
To see how to find these values, see those sections in the spec below.

Add this action to your repo as .github/workflows/readme-stars.yml, pasting in your user ID and the leaderboard ID to pull data from (or remove this argument to default to your own private leaderboard):

name: Update README ⭐
on:
  schedule:
    - cron: "51 */4 * * *"  # Every 4 hours
  workflow_dispatch:

jobs:
  update-readme:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: k2bd/advent-readme-stars@v1
        with:
          userId: 1234567
          leaderboardId: 9876543
          sessionCookie: ${{ secrets.AOC_SESSION }}
      - uses: stefanzweifel/git-auto-commit-action@v4
        with:
          commit_message: Update README stars

If you want to adjust the cron expression, please remember to schedule your jobs such that you respect the Advent of Code request of running automated requests at a rate of no more than 1 per 15 minutes.

Action Spec

userId

Required

Your Advent of Code user ID.
To get this, go to your Go to settings.
The user ID is displayed in the first option of the question “What would you like to be called?”:

( ) (anonymous user #<your ID>)
( ) ....

sessionCookie

Required

Your Advent of Code session cookie.
To get this, press F12 anywhere on the Advent of Code website to open your browser developer tools.
Look in your Cookies under the Application or Storage tab, and copy out the session cookie.
This should be stored as a repository secret, not pasted directly into the action or any other publicly viewable place.

leaderboardId

Optional – default userId value

Your Advent of Code leaderboard ID.
To get this, go to your Go to leaderboard and press ‘View’.
The leaderboard ID is at the end of the URL:

https://adventofcode.com/2021/leaderboard/private/view/(leaderboard ID)

tableMarker

Optional – default <!--- advent_readme_stars table --->

This is the string that marks the table location in your README file. The action will only work if it finds this marker in your file, on its own line. You should only add it once, and then let the action do its work.

Change this value if, for example, you’d like different actions maintaining different year results. However, remember to schedule your jobs such that you respect the Advent of Code request of running automated requests at a rate of no more than 1 per 15 minutes.

starSymbol

Optional – default ⭐

The symbol that will mark completed parts in your table.

year

Optional – default is year of the most recent advent

Year to get results for.
By default, it will get results for the year of the most recent advent.
That is, this year if it’s December, otherwise last year.

headerPrefix

Optional – default ##

Prefix for the section header added before the table.
Should be some kind of Markdown header level.

readmeLocation

Optional – default README.md

Location of the README file to edit.
