Install Dependencies

Start the Julia REPL (make sure the environment is activated) and download and compile dependencies:

julia> ]
(julia) pkg> instantiate
(julia) pkg> precompile

Run the Solutions

Enter the puzzle directory, and run the Julia solution file:

$ cd 2015/01_not_quite_lisp/
$ julia aoc201501.jl input.txt

Bootstrap a Puzzle Solution

TODO: Create a Copier task that creates a new Julia puzzle template

Run Tests

You can test all solutions by running:

$ julia test_all_puzzles.jl

Note that the tests are done by running the puzzle solutions on the input.txt file in each puzzle directory and comparing the output to a output.jl.txt file in the same directory.

You can include a benchmarking report by adding the -r option:

$ julia test_all_puzzles.jl -r

This will create a file named timings.jl.md that contains timing information for each puzzle.

Adding a Solution to GitHub

Follow these steps after solving a puzzle:

1. Store the solution to an output file:

   $ cd 2015/01_not_quite_lisp/
   $ julia aoc201501.jl input.txt > output.jl.txt

2. Run benchmarks and add them to the README:

   $ cd ../..
   $ julia test_all_puzzles.jl -r

3. Update READMEs across all projects:

   $ cd ..
   $ make
