Darcs is a distributed version control system written in Haskell.
To build and install the latest release, use
cabal update && cabal install darcs
with a recent cabal (version 3.2 or later is recommended). Any version of ghc from 8.2 up to 9.4 should work.
From inside a clone or a source dist, use
> cabal build
Cabal will tell you where the resulting darcs binary is. If you'd rather use
cabal install and you are in a clone (not a source dist), you first have to generate the version info, like this:
> runghc release/gen-version-info.hs > cabal install
Building/installing with stack used to work with a few tweaks, but is no longer officially supported due to lack of manpower. If this inconveniences you, consider contributing patches to maintain our stack.yaml.
Running the test-suite is optional, of course, but useful if you want to help find bugs or before you contribute patches. The easiest and most flexible way to do this is
> cabal configure --enable-tests > cabal run darcs-test -- [options for darcs-test, try --help]
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 email@example.com: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
The complete documentation is available as a man page which can be generated using
darcs help manpage > darcs.1
