The Darcs team is pleased to announce the release of Darcs 2.12.0.
One way of installing Darcs 2.12.0 is with stack:
$ stack install darcs-2.12.0
Or first install the Haskell Platform (http://www.haskell.org/platform)
and install Darcs with cabal-install:
$ cabal update
$ cabal install darcs-2.12.0
You can also download the tarball from
http://darcs.net/releases/darcs-2.12.0.tar.gz and build it by hand.
The 2.12 branch is also available as a darcs repository from
Patch dependency graph export
The new command `darcs show dependencies`, enables to export the dependency graph of a repository (up to the latest tag, by default) as a Graphviz file:
whatsnew output and third-party VC frontend support
The flag `whatsnew --machine-readable` is a simplified version of `whatsnew -s` for easier parsability by third-party tools. Darcs 2.12 adds conflict markers to the output of whatnew when summarized (ie, when used with the `-s` or `--machine-readable` flags or via the `darcs status` alias). Thanks to this, Darcs support was reintroduced in meld 3.15.2
improvements for Git repository imports
File moves are converted to file moves primitives, instead of being file deletes and add as before. This enables to have smaller Darcs respositories with a more understandable history. This change adds to other improvements and fixes that make Git import more practical.
repository Weak Hashes
The command `darcs show repo` now shows a hash that is the XOR
of all hashes of the patches metadata of the repository. Being a XOR,
it does not depend on the patches' ordering. Also it is quite fast to
calculate. This Weak Hash can be useful to quickly check whether two
repositories of a single proyect have the same patches.
