abridge

Compress a sorted word list or decompress a file compressed by abridge or GNU word-list-compress.

abridge is a port of GNU word-list-compress to Rust. It doesn't have anything to do with the GNU Aspell project.

abridge is both a Rust library and CLI, so you can use abridge in your Rust project or run it by itself. The CLI expects input from stdin and will output to stdout.

It only relies on clap and Rust's built-in substring crate.

word-list-compress is about 150 SLOC. abridge is about 50 SLOC. They perform identically.

Install

You'll need the Rust compiler and Cargo. The easiest way to do that is to get rustup.

shell cargo install abridge

Usage

See abridge --help.

Examples

shell abridge -c < words.txt # compress words.txt

shell abridge --decompress < words.tzip # decompress words.tzip

shell abridge --compress < words.txt > words.tzip # compress words.txt and save to words.tzip

Safety

abridge can compress word lists where:

• Words are in alphabetical order
• Words are separated by newline
• Words contain ASCII characters

Words may include uppercase characters, but use lowercase for the best results.

abridge can decompress files compressed by abridge or word-list-compress alike.

Testing

Run cargo test.
