darcs is a peer-to-peer revision control system, written in Haskell.
1 Understanding darcs
You can think of a darcs repository as containing these things:
- Patches: a patch is a collection of changes that forms the unit of synchronisation with other repositories
- Unrecorded changes to known files and directories
- Unknown items (files and directories)
- Boring items: anything with a name matched in _darcs/prefs/boring
Note that some projects are keen on making sure all derivative items are "boring" rather than merely unknown items that will show up with darcs wh -l. Other projects less so.
2.1 Unknown items
- darcs whatsnew -l: show changes and unknown items
- creating a item: these will be "unknown".
- darcs add: turns an unknown item into a change
- darcs remove: creates an change to remove the item but keeps it as an unknown item.
- darcs whatsnew: show unrecorded changes
- removing an item: creates a change to remove the item
- editing a file adds to the edit to the changes
- darcs mv: create a change to move an item
- darcs replace: create a change to replace text in a file
- darcs record: record changes as a patch
- darcs changes: show patches
- darcs pull: get patches from another repository
- darcs push: put patches in another repository
- darcs apply: get patches from an email bundle
- darcs rollback: adds a patch that is the inverse of an existing patch
- darcs obliterate: removes a patch. Warning: if the patch doesn't exist elsewhere, you will lose that work.
- darcs initialize: create a new empty repository
- darcs get: create a new empty repository and get patches from another repository
