Based on @davekch's template

Download today's puzzle input from adventofcode, create a directory for this day and some template files to solve the puzzle in a given language. Includes templates and utility libraries for the following languages:

• python
• julia
• haskell
• C++

• python3
• requests (pip3 install requests)
• if you want to get your puzzle input downloaded automatically,
  • log into adventofcode via your browser and get the content of the session cookie
  • in your terminal, do export AOC_SESSION=your-session-id

This repository can either be used as a template repository or as a submodule.

$ python3 init.py --help
usage: init.py [-h] [-d DAY] [-y YEAR] [-l LANGUAGE [LANGUAGE ...]]
               [--no-download]

optional arguments:
  -h, --help            show this help message and exit
  -d DAY, --day DAY
  -y YEAR, --year YEAR
  -l LANGUAGE [LANGUAGE ...], --language LANGUAGE [LANGUAGE ...]
  --no-download

If no day / year is given, the current date is used. language defaults to py.

The script creates a folder for the day in the current working directory and copies all files for the given language from templates/<language>/ into it.

For example, to solve today's problem in Julia, do

$ export AOC_SESSION=your-session-id
$ python3 init.py -l jl

Templates are in templates/py. Do pip install -e utils/py to install the utility module aoc.utility.

$ python init.py
$ cd dayXX
$ pytest   # pip install pytest
$ python solver.py

Templates are in templates/jl. Do ] dev utils/jl to make the utility module AoC available in your environment.

$ python init.py -l jl
$ cd dayXX
$ julia
julia> push!(LOAD_PATH, pwd())
julia> using Revise
julia> using Solver
julia> test()  # or test(1) or test(2)
julia> main()  # or main(1) or test(2)

Revise hot reloads code in Solver.jl, so code along and just keep your REPL running.

Templates are in templates/hs

dependencies: cabal install split optparse-applicative raw-strings-qq vector parsec

$ python init.py -l hs
$ cd dayXX
$ ghc -i../utils/hs solver.hs
$ ./solver

Run tests with ./solver --test or in the repl:

$ ghci -i../utils/hs solver.hs
λ> test1
λ> test2

You can also run only part one or two with ./solver --part 1.

Utilities are in utils/hs

requires cxxtest: sudo apt-get install cxxtest

Templates are in templates/cpp

$ python init.py -l cpp
$ cd dayXX
$ make test
$ make run

Utilities are in utils/cpp. cd utils/cpp; make to test Utils.cpp
