formula 0.0.1

It's in its early stages, and we are trying to add more functions and features soon.

So far we have the following features:

• 18 date time functions
• 26 text functions

Installation and usage

Add this library to your project with cargo add formula or add formula = "*" to your Cargo.toml file.

Use it similar to the following code:

use formula::{Formula, Expr, error::Error};
use anyhow::Result;

fn main() -> Result<()> {
    let formula = Formula::new("UPPER(TRIM('   Hello '))")?;
    let value = formula.parse().unwrap();
    assert_eq!(value, Expr::String("HELLO".to_string()));
    Ok(())
}

What we do not support:

• We would like to add more functions, like Excel functions, Google Sheets functions, and more
• At the moment, we don't support table data, so you need to pass values to the formula as arguments by yourself
• We do not support simple formulas like 1+1 or as argument like AND(1>3, 1<3) or SUM(2-1, 2), yet
