darcs is a peer-to-peer revision control system, written in Haskell.
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.
- darcs whatsnew -l: show changes and unknown items
- creating a item: add item to the unknown items.
- darcs add: convert the unknown item into a change to create the item and its contents
- darcs remove: add a change to empty the item and delete it but keep it as an unknown item.
- darcs whatsnew: show unrecorded changes
- removing an item: add a change to remove the item
- editing a file: add a change for the edit
- darcs mv: add a change to move an item
- darcs replace: add a change to replace text in a file
- darcs record: record changes to add a patch
- darcs unrecord: remove a patch by turning back it into unrecorded changes
- darcs amend-record: replace a patch with one with added changes
- darcs changes: show patches
- darcs send: make an email bundle from patches, and optionally send it
- darcs pull: add patches from another repository
- darcs push: add patches from this repository to another repository
- darcs apply: add patches from an email bundle
- darcs rollback: add a patch that is the inverse of an existing patch
- darcs obliterate: remove 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 add patches from another repository
