fmtastic ✨

Docs Crate Version

A fantastic, #![no_std]-friendly crate for fmting numbers using the appropriate unicode characters via the Display trait. ✨ Format as vulgar fractions, super- and subscript and more.

Contributions are welcome for more formats.

Features

Creates beautiful unicode fractions like ¼ or ¹⁰⁄₃.

use fmtastic::VulgarFraction;

assert_eq!("¹⁰⁄₃", format!("{}", VulgarFraction::new(10, 3)));
assert_eq!("¼", format!("{}", VulgarFraction::new(1, 4)));

Sub- and superscript

Formats integers as sub- or superscript.

use fmtastic::{Subscript, Superscript};

assert_eq!("x₁", format!("x{}", Subscript(1)));
assert_eq!("n²", format!("n{}", Superscript(2)));

Roman Numerals

Formats unsigned integers as Roman numerals.

use fmtastic::Roman;

assert_eq!("ⅾⅽⅽⅼⅹⅹⅹⅰⅹ", format!("{:#}", Roman::new(789_u16).unwrap())); // lowercase
assert_eq!("ⅯⅯⅩⅩⅠⅤ", format!("{}", Roman::new(2024_u16).unwrap()));
assert_eq!("MMXXIV", format!("{}", Roman::new(2024_u16).unwrap().ascii())); // ascii
assert_eq!("ⅠⅠⅠ", format!("{}", Roman::from(3_u8))); // u8's can always be formatted as Roman numeral

Seven-Segment Digits

Formats an unsigned integer using seven-segment digits from the Legacy Computing block.

use fmtastic::Segmented;

assert_eq!("🯶🯲🯸", format!("{}", Segmented(628_u32)));

Outlined

Formats an unsigned integer using outlined digits from the Legacy Computing Supplement block.

use fmtastic::Outlined;

assert_eq!("𜳶𜳲𜳸", format!("{}", Outlined(628_u32)));

Tally Marks

Formats an unsigned integer as tally marks.

use fmtastic::TallyMarks;

assert_eq!("𝍷𝍷𝍷", TallyMarks(3_u32).to_string());
assert_eq!("𝍸𝍸𝍷𝍷", TallyMarks(12_u32).to_string());

Ballot Box

Formats a boolean as a ballot box.

use fmtastic::BallotBox;

assert_eq!("☑ Buy bread", format!("{} Buy bread", BallotBox(true)));
assert_eq!("☐ Do the dishes", format!("{} Do the dishes", BallotBox(false)));
assert_eq!("☒ Laundry", format!("{:#} Laundry", BallotBox(true)));
