AoC 2020

Mixed C++/JS for Advent of Code, 2020.

Most days have C++ solutions; if I was busy that day, or fancied some code golf, there is a JS solution instead or as well.

Building

The JS solutions don't require building.

The C++ solutions are built as a single CMake project, with a separate binary for each day. Set up is as usual for CMake projects: for example, on Linux and using the makefile generator, I use the following.

build_dir=build/debug
mkdir -p "$build_dir"
cmake -DCMAKE_BUILD_TYPE=Release -B "$build_dir"
make -C "$build_dir"

Running

You can each day's code as follows.

• JS: ./$day/main.js [input-file]
• C++: "$build_dir/$day/main" [input-file].

The input file is optional, and defaults to $day/input.txt. Where example inputs are given, those examples are often included too, as e.g. $day/example.txt, $day/example-long.txt, etc. Some programs allow for extra input, where parameters for the example inputs differ from those for the input.txt.
