Cha(rs)

Build Status

Use this tool to display names and codes for various ASCII (and unicode) characters / code points!

It's strongly inspired by ascii(1), but supports unicode characters; it's also inspired by unicode.py, but it attempts to support whitespace/control characters better.

Cha(rs) is currently probably failing at some other edge case, but I hope not.

Pronunciation

How do you pronounce "chars"? This is a contentious thing.

Installation

This package is tested on circle CI using the latest stable, beta and nightly releases. Older releases might work, but I'm focusing development mostly on the latest versions.

Plain crate installation without source code

cargo install chars --git https://github.com/antifuchs/chars.git

OS packages

Arch linux: There's an AUR package for chars.

Windows: There's a package available through Chocolatey.

Source installation

  1. Clone this repo,
  2. cd into the checkout,
  3. cargo install --path chars
