Advent of CLJC

Cross platform Clojure Advent of Code solutions.

Contribute

What's in it for you?

• Most of all, you will be encouraged to write portable Clojure code: a solution that runs on the JVM via Clojure and on Node via ClojureScript.
• Your Advent of Code solutions will be checked against the same input as others. This diminishes the possibility that your solution only works for your specific input.
• The performance of your solution can be compared with others via CircleCI (see Scores).

What's in it for the Clojure community?

• You are helping advance the speculative project, a collection of core specs.
• You are helping to build a large Clojure corpus for various purposes (see the Rationale for coal-mine).

PRs welcome. Make a new solution file with the new script:

script/new 2017 1 username

where username is your Github or Bitbucket username. Then fill in the solution in the file. If the input and answers are still empty you will have to provide it in data.cljc.

This repo will not accept multiple inputs and answers (see this issue for details).

Dev

Read here how to get an nREPL for this project.

Tests

Make sure the tests for your solution pass with the test-one script.

Please do not run calculations outside the tests. Memoized functions are permitted. Top-level lazy sequences are fine as long as they are not realized outside the tests.

CircleCI runs tests for changed namespaces with the .circle/test-diff script.

Tests support the following metadata:

• :skip-cljs: used for skipping Node tests. Used in .circle/test-diff, script/test and script/test-one.
• :skip: used for skipping tests in script/test.

Run all tests:

script/test

Run one test:

script/test-one 2017 1 username

Run with instrumentation:

INSTRUMENT=true script/test
INSTRUMENT=true script/test-one aoc.y2017.d01.username

Skip Clojure or ClojureScript:

SKIP_CLJ=true script/test
SKIP_CLJS=true script/test

Scores

To view a time comparison of your solutions to others, go to CircleCI, open "Test changed namespaces" and scroll to the end.
