English to CronJob Syntax Converter

This project is inspired by the library natural-cron, which converts natural language into cron expressions. english-to-cron brings similar functionality to the Rust ecosystem, allowing developers to easily schedule cron jobs using English text.

Features

• Converts various English text descriptions into cron job syntax.
• Supports complex patterns including specific days, time ranges, and more.
• Handles multiple time formats including AM/PM and 24-hour notation.

Installation

Add the following line to your Cargo.toml under [dependencies]:

english_to_cron = "0.1" 

Usage

Simply provide an English phrase describing the schedule, and the library will return the corresponding cron job syntax.

use english_to_cron::str_cron_syntax;

fn main() {
    assert_eq!(str_cron_syntax("every 15 seconds").unwrap(), "0/15 * * * * ? *");
    assert_eq!(str_cron_syntax("every minute").unwrap(), "0 * * * * ? *");
    assert_eq!(str_cron_syntax("every day at 4:00 pm").unwrap(), "0 0 16 */1 * ? *");
    assert_eq!(str_cron_syntax("at 10:00 am").unwrap(), "0 0 10 * * ? *");
    assert_eq!(str_cron_syntax("Run at midnight on the 1st and 15th of the month").unwrap(), "0 0 0 1,15 * ? *");
    assert_eq!(str_cron_syntax("on Sunday at 12:00").unwrap(), "0 0 12 ? * SUN *");
}
