Solving Advent of Code problems in Clojure and Java to get hands-on fun experience with the language.
Each day I write down a "Today I Learned" (TIL) so I don't just solve the problem, but also keep track of what I've learned, tricks I found, or just problems I liked.
λ🎄.(λ🎅.🎄(🎅🎅))(λ🎅.🎄(🎅🎅))
- Learn Clojure (XinYMinutes) <-- Start here if you're totally new to Clojure
- Clojure Cheatsheet
- ClojureDocs - community examples
- Associative (Map) Destructuring
- regex.Pattern
Prerequisites:
- Install Java
- Install Clojure
- Install Leiningen
Highly Recommended:
- IntelliJ: the best Java IDE
- Note: IntelliJ has a free Community Edition
- Cursive: IntelliJ plugin that adds Clojure support
- Note: Cursive has a free license for non-commercial
$ lein repl
# repl starts. use -main as a sanity check
advent-clj.core=> (-main)
λ🎄.(λ🎅.🎄(🎅🎅))(λ🎅.🎄(🎅🎅))
$ lein run
$ lein uberjar
# The resulting standalone can be run by java, from anywhere, and executes core.clj
$ java -jar target/uberjar/advent-clj-0.1.0-SNAPSHOT-standalone.jar
$ lein javac
# Howdy is a basic hello world example
$ java -cp target/default/classes/ com.valbaca.advent.Howdy
If you get ClassNotFound when running a method in Clojure in IntelliJ, configure the following:
- How to run it
- Run with Leiningen
- Profiles: dev
- Run with Leiningen
