Darcs
A distributed revision control system.
Overview
Darcs is an open-source distributed version control system that was one of the pioneers of the patch-based approach. It emphasizes the ability to choose which changes to push, pull, or merge between repositories. Its core concept is the 'theory of patches', where each change is an independent entity that can be manipulated, which simplifies many complex operations compared to snapshot-based systems.
✨ Key Features
- Patch-based model
- Interactive commands for cherry-picking changes
- Spontaneous branching (repositories are branches)
- Free and open source
🎯 Key Differentiators
- Interactive patch selection is core to the workflow
- Patch theory simplifies understanding of history and merges
- User-friendly command-line interface
Unique Value: A version control system that provides powerful, interactive control over individual changes (patches), making it easy to move them between branches and repositories.
🎯 Use Cases (3)
✅ Best For
- Managing its own source code and the source for various Haskell projects
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Large-scale projects with performance demands (known to have performance issues)
- Mainstream enterprise development
🏆 Alternatives
Provides a more intuitive model for cherry-picking changes than Git. However, it suffers from performance problems (the 'exponential merge' problem) that Pijul aims to solve. Its ecosystem and community are vastly smaller than Git's.
