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

Contents

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 Operations

2.1 Unknown items

  • 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.

2.2 Changes

  • 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

2.3 Patches

  • 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 tag: add a tag for the current set of patches

2.4 Repositories

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