Kompare is KDE’s graphical application for inspecting differences between files and directory trees. It turns diff output into a visual comparison, making it easier to step through changes, understand patches and decide which differences should be applied.
The application is useful for source code, configuration files and ordinary text documents. It can work with direct file or folder comparisons as well as existing patch data, avoiding the need to interpret raw diff output by hand.
Its workflow centres on visually inspecting source and destination content and working with the differences between them.
This is free and open source software.
Key Features
- Compare individual files through a graphical interface.
- Compare the contents of folders recursively.
- Support a variety of diff formats.
- Customise the amount of comparison information displayed.
- Create patches from differences between source and destination content.
- Open patch data for visual inspection.
- Apply patches and merge differences through the graphical interface.
- Provide a clearer way to inspect multi-file changes than reading raw diff output.
