My advent of code submissions.

Dependencies

• To run the solutions:
  • node
  • yargs
  • chalk
  • ngraph.path
  • ngraph.graph
• To get linting info (if you're modifying the solutions):
  • eslint

You can install them easily by running the following command from the project root directory:

$ yarn install

or

$ npm install

Running the Solutions

To run a particular solution (01/, 02/, 03/, ..., 25/), you can execute the following from the project root directory (for example, 01):

$ node 2021/01/index.js

or (with bash):

$ ./2021/01/index.js

When using the ./ syntax, you may need to chmod the file first:

$ chmod +x ./2021/01/index.js

This will allow you to execute the file as your user.

Options/Flags

Each solution can make use of the following (optional) flags:

--help / -h

Reminds you how to use the following flags.

--verbose / -v

Causes the solution to provide (optional) verbose output. (For example):

$ node 2021/01/index.js --verbose

This usually means any intermediate calculations or values will be shown in the console. The result of each solution (both parts) will always be shown at the end of all logging, regardless of the verbose flag.

--file / -f [path]

Specifies a custom file for the solution to process. Your path should be relative to the root directory. Spaces in the path are fine, just wrap it with quotes! For example:

$ node 2021/01/index.js --file ./2021/01/custom_input.txt

...

$ node 2021/01/index.js --file "./2021/01/I use spaces in my paths for some reason.txt"

The standard naming convention I use for the input file is input.txt. If the default input.txt is found in a solution's folder (for example, ./01/input.txt), you may exclude the file flag.
