ydiff is a terminal viewer for coloured incremental diff output. It can work within a version-controlled workspace or consume unified diff data from standard input, presenting changes either side by side or in a colourised unified layout.
It is deliberately lightweight and depends only on Python’s standard library. This makes it useful as a pager or formatting layer around existing version-control and diff commands rather than as a replacement comparison engine.
This is free and open source software.
Key Features
- Displays unified diffs in a colourised side-by-side view.
- Can switch to a colourised unified layout when a two-column presentation is not desirable.
- Automatically detects a suitable display width from the terminal.
- Wraps long lines or can leave them unwrapped according to user preference.
- Automatically feeds output to a pager and lets users select the pager and its options.
- Works from standard input, making it suitable for Git logs, Git show output, patches and ordinary diff output.
- Can inspect local modifications and revision history from supported version-control workspaces.
- Supports Git, Mercurial, Subversion and Perforce workflows.
- Supports Jujutsu version-control workflows.
- Provides built-in light, dark and default colour themes.
- Allows additional themes to be defined in an INI configuration file.
- Supports configurable tab width and terminal colour behaviour.
- Passes unrecognised command-line options through to the underlying revision-control command.
- Can compare files and directories when supplied with suitable unified diff input.
