Title Case (titlecase)

titlecase is a small tool that capitlizes text according to a style defined by John Gruber for post titles on his website Daring Fireball. titlecase runs on Linux, macOS, FreeBSD, NetBSD, and Windows. A dependency free, single file binary is built for each supported platform for every release.

titlecase is licensed under the MIT license.

Finding an Alternative to Mac OS X — Part 2

% echo 'an example with small words and sub-phrases: "the example"' | titlecase
An Example With Small Words and Sub-Phrases: "The Example"

Usage

titlecase reads lines of text from stdin and prints title cased versions to stdout.

Installation

Pre-built titlecase binaries are available for Linux, macOS, FreeBSD, NetBSD, and Windows.

Rust Developer/Cargo

If you have a stable Rust compiler toolchain installed you can install titlecase with cargo:

% cargo install titlecase

Style

Instead of simply capitalizing each word it does the following (amongst other things):

• Lower case small words like an, of, or in.
• Don't capitalize words like iPhone.
• Don't interfere with file paths, URLs, domains, and email addresses.
• Always capitalize the first and last words, even if they are small words or surrounded by quotes.
• Don't interfere with terms like "Q&A", or "AT&T".
• Capitalize small words after a colon.
