Getting Started

Installing a prebuilt package

Prebuilt packages are available on the following platforms.

Packaging status

Installing from source

Build Requirements

Difftastic is written in Rust, so you will need Rust installed. I recommend rustup to install Rust. Difftastic requires Rust version 1.56 or later.

You will also need a C++ compiler that supports C++14. If you're using GCC, you need at least version 8.

Build

You can download and build difftastic on crates.io with Cargo (which is part of Rust).

$ cargo install difftastic

Difftastic uses the cc crate for building C/C++ dependencies. This allows you to use environment variables CC and CXX to control the compiler used (see the cc docs).

See contributing for instructions on debug builds.

Diffing Files

$ difft sample_files/before.js sample_files/after.js

Difftastic uses the file extension to decide which parser to use.

Diffing Directories

$ difft sample_files/dir_before sample_files/dir_after

Difftastic will recursively walk the two directories, diffing files with the same name.
