Puzzler

Puzzler is a Go (golang) program wrapper to assist in developing solutions to various programming puzzles. An internet connection is only required to fetch the questions. Current, it supports Advent of Code.

Quick start

Use this template repo https://github.com/jpillora/aoc-in-go

Alternatively, you can setup manually by following the steps below

Advent of Code

Advent of Code is a yearly series of programming questions based on the Advent Calendar. For each day leading up to christmas, there is one question released, and from the second it is released, there is a timer running and a leaderboard showing who solved it first.

1. Manually install Go from https://go.dev/dl/ or from brew, etc

2. Make an AOC solutions directory and initialise it as a Go module

   mkdir -p my-aoc-solutions
   cd my-aoc-solutions
   go mod init my-aoc-solutions
   

3. Make a directory and file YYYY/DD/code.go where YYYY/DD is the AOC year/day you'd like to attempt

   mkdir -p 2022/09/
   touch 2022/09/code.go
   

4. Paste the following into code.go

   package main
   
   import (
   	"github.com/jpillora/puzzler/harness/aoc"
   )
   
   func main() {
   	aoc.Harness(run)
   }
   
   func run(part2 bool, input string) any {
   	if part2 {
   		return "not implemented"
   	}
   	return 42
   }
   

5. Run code.go

   go run main.go
   

6. You should see

   $ go run code.go
   Created file README.md
   Created file input-example.txt
   run(part1, input-example) returned in 37µs => 42
   # update code.go to return 43 and...
   file changed code.go
   run(part1, input-example) returned in 34µs => 43
   

7. You can find your question in README.md, iterate on code.go until you get the answer

AOC Session

Optionally, you can set AOC_SESSION to your adventofcode.com session cookie. That is:

• Login with your browser
• Open developer tools > Application/Storage > Cookies
• Retrieve the contents of session
• Export it as AOC_SESSION

With your session, puzzler will download your user-specifc input-user.txt and also update README.md with part 2 of the question once you've completed part 1.

Current, your session is NOT used to submit your answer. You still need to login to https://adventofcode.com to submit.

Leetcode

TODO

• https://leetcode.com

• Problem: Leetcode's programming model is different from AOC. Its not text in, text out. There are structured questions and code samples and other differences that make it tricky.

• Goal: Make the harness API work like:

  func main() {
  	leetcode.Harness(run)
  }
  

TODO

• Submission
  • Requires AOC_SESSION
  • Press s to submit your most recent pending result the next part
• Press r to re-run your program
• Press c to cancel any running program
