Math Text Transform

Travis build crates.io

A simple crate that provides functions to map a greek letter, latin letter, or a decimal digit to a certain variant from the mathematical alphanumeric symbols Unicode block (U+1D400–U+1D7FF). We also provide convenience string methods that maps each character in a string to the variant (or leaves it alone if there is none).

Supported variants are:

  • 𝐛𝐨𝐥𝐝 (bold)
  • 𝑖𝑡𝑎𝑙𝑖𝑐 (italic)
  • 𝒃𝒐𝒍𝒅 𝒊𝒕𝒂𝒍𝒊𝒄 (bold italic)
  • 𝗌𝖺𝗇𝗌-𝗌𝖾𝗋𝗂𝖿 (sans-serif)
  • 𝘀𝗮𝗻𝘀-𝘀𝗲𝗿𝗶𝗳 𝗯𝗼𝗹𝗱 (sans-serif bold)
  • 𝘴𝘢𝘯𝘴-𝘴𝘦𝘳𝘪𝘧 𝘪𝘵𝘢𝘭𝘪𝘤 (sans-serif italic)
  • 𝙨𝙖𝙣𝙨-𝙨𝙚𝙧𝙞𝙛 𝙗𝙤𝙡𝙙 𝙞𝙩𝙖𝙡𝙞𝙘 (sans-serif bold italic)
  • 𝓈𝒸𝓇𝒾𝓅𝓉 (script)
  • 𝓫𝓸𝓵𝓭 𝓼𝓬𝓻𝓲𝓹𝓽 (bold script)
  • 𝔣𝔯𝔞𝔨𝔱𝔲𝔯 (fraktur)
  • 𝖇𝖔𝖑𝖉 𝖋𝖗𝖆𝖐𝖙𝖚𝖗 (bold fraktur)
  • 𝚖𝚘𝚗𝚘𝚜𝚙𝚊𝚌𝚎 (monospace)
  • 𝕕𝕠𝕦𝕓𝕝𝕖-𝕤𝕥𝕣𝕦𝕔𝕜 (double-struck)


Add this to your Cargo.toml:

math-text-transform = "*"


extern crate math_text_transform;
use math_text_transform::MathTextTransform;

assert_eq!("Bold".to_math_bold(), "𝐁𝐨𝐥𝐝");
assert_eq!("Σανσ-Σεριφ-Βολδ".to_math_sans_serif_bold(), "𝝨𝝰𝝼𝞂-𝝨𝝴𝞀𝝸𝞅-𝝗𝝾𝝺𝝳");
assert_eq!("Double-struck 123".to_math_double_struck(), "𝔻𝕠𝕦𝕓𝕝𝕖-𝕤𝕥𝕣𝕦𝕔𝕜 𝟙𝟚𝟛");



CLI utility

If you are for some reason only interested in the CLI utility you can install with:

$ git clone https://github.com/runarberg/math-text-transform.git
$ cd math-text-transform
$ cargo build --release
$ [sudo] ln -s $(pwd)/target/release/math-text-transform /usr/local/bin/math-text-transform

And use like so:

math-text-transform <variant> <text>

Text can also be supplied through the standard input.


$ math-text-transform -bf-it Bold-Italic
$ echo "Double struck" | math-text-transform --double-struck
𝔻𝕠𝕦𝕓𝕝𝕖 𝕤𝕥𝕣𝕦𝕔𝕜
