Darcs

darcs is a peer-to-peer revision control system, written in Haskell.

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.

Operations

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 -l: show changes and unknown items

Changes

• removing an item: creates a change to remove the item

• editing a file adds to the edit to the changes

• darcs whatsnew: show 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

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.

Repositories

• darcs initialize: create a new empty repository

• darcs get: create a new empty repository and get patches from another repository
