Macro add_days

add_days!() { /* proc-macro */ }

A procedural macro that generates boilerplate code for Advent of Code solution modules.

This macro takes a comma-separated list of day numbers and generates:

• Individual modules for each day which have to be populated with your solutions

Arguments

• Takes a comma-separated list of expressions representing the day numbers (e.g., add_days!(1..10, 12, 13))

Generated Code

For each day number, the macro:

1. Creates a module declaration (mod dayXX)
2. Generates a HashMap mapping day numbers to solution implementations which is accessed by the CLI

Example

add_days!(1, 2, 15);

This will generate:

• Modules: mod day01;, mod day02;, mod day15;
• Solution mapping in a HashMap
