darcs: a distributed, interactive, smart revision control system

[ development, gpl, library ] [ Propose Tags ]

Darcs is a free, open source revision control system. It is:

  • Distributed: Darcs was one of the first revision control systems in which every user has access to the full command set, removing boundaries between server and client or committer and non-committers.

  • Interactive: Darcs is easy to learn and efficient to use because it asks you questions in response to simple commands, giving you choices in your work flow. You can choose to record one change in a file, while ignoring another. As you update from upstream, you can review each patch, picking and choosing which patches are appropriate.

  • Smart: Darcs is different from most revision control systems in that it is based on the notion of change (or patch), rather than version. An underlying algebra of patches determines whether changes can be re-ordered. The laws of this algebra guarantee that the result of merging depends only on the final set of patches applied in a repository and not on their order.

  • Simple: As a consequence, Darcs offers a conceptually simpler view of the state of a repository: it is given by the set of patches it contains. Pulling and pushing patches merely transfers them from one set to another. So called "cherry-picking" is the default mode of operation, and it fully preserves the identity of patches.

Readme for darcs-2.16.2

[back to package description]

Darcs

Darcs is a distributed version control system written in Haskell.

Getting started

Compiling

The easiest way to build darcs is by using cabal-install version 3.2 or later. A plain

> cabal build

or

> cabal install

should work out of the box with any ghc version from 8.0 up to 8.10.

Run the test suite

It is currently not possible to run the full test suite from the source distribution that you get from hackage. Instead you need to be in a clone of the darcs source code repository. This is because the tests depend on an old version of shelly that was patched to work with newer ghc versions and bundled with Darcs. It is not part of the source distribution to avoid 'cabal install' also trying to install our patched version of shelly.

> cabal build --enable-tests
> cabal test --test-show-details=direct

Using

To clone a repository via HTTP and send patches by mail:

> darcs clone --lazy http://darcs.net
> # edit files...
> darcs add my_new_file
> darcs record -m "my changes"
> darcs send

To clone via SSH and push patches:

> darcs clone user@hub.darcs.net:user/repo
> # edit files...
> darcs add my_new_file
> darcs record -m "my changes"
> darcs push

To create a project and start working:

> darcs init my_project
> cd my_project
> # create and edit files...
> darcs add my_new_file
> darcs record -m "initial version"

Pull new patches from upstream:

> darcs pull

Concise and up-to-date documentation is available from darcs itself:

> darcs help # list all commands
> darcs help command # help for specific command
> darcs command --help # dito
