unicode-categories

unicode-categories is a simple crate that adds many extensions to the char type that allow for the querying of whether or not a character is a member of a certain category of unicode characters.

use unicode_categories::UnicodeCategories;

assert!('a'.is_letter_lowercase());
assert!('A'.is_letter_uppercase());
assert!('\n'.is_other_control());

This crate can be obtained from crates.io and used as a dependency like any other crate.

Regenerating the tables

The script in scripts/unicode.py reads a file named UnicodeData.txt, which is assumed to be in the current working directory. This file can be obtained from ftp://ftp.unicode.org . The script outputs a rust file to standard out, which can be piped to the desired location.
