Advent Of Code

A simple framework to include in all Advent of Code solutions in a single framework to make it easy to call it with the appropriate CLI arguments.

Installation

Have a proper full Rust installation (see rustup.rs for more). Clone this repository such as via:

git clone https://github.com/OvermindDL1/advent_of_code.git
cd advent_of_code

Then build it by:

cargo build --release

If following the above instructions then the final program will be at:

./target/release/advent_of_code

And as such it will be used as the executable path, feel free to move it elsewhere.

See the help with the --help flag or the help command such as:

./target/release/advent_of_code --help

The --help flag and help command works on other commands as well, such as seeing the help for one of the years by:

./target/release/advent_of_code 2020 --help

To run, for example, the Advent of Code 2020 Day 1 then run:

./target/release/advent_of_code 2020 1 ./inputs/2020/day1.input

Or use your own input to get your own answer (please try to answer Advent Of Code on your own, don't just copy and paste answers from elsewhere).

You can see what arguments are needed for a task by showing its --help like such:

./target/release/advent_of_code 2020 1 --help

To see the running time of the command then add the -v for verbose as the first argument, such as with:

./target/release/advent_of_code -v 2020 1 ./inputs/2020/day1.input

Feel free to add more v's such as -vvv for more detailed logging, but just one will print the times for the runs.

If you want test the example of your problem then you can send it in via a heredoc if using a good modern shell, such as via:

cargo run --release -- 2020 1 <(cat <<EOI
1721
979
366
299
675
1456
EOI
)

Everything within the <() is passed as a fake file/pipe via the shell to the program.
