Questions tagged [darcs]

A distributed source code management system, with a simple command-line UI and precise merging.

Blurb from the Darcs website, http://darcs.net/:

Darcs is a free, open source source code management system.

Distributed

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 name, even the full "diff" for interesting patches.

Smart

Originally developed by physicist David Roundy, darcs is based on a unique algebra of patches. This smartness lets you respond to changing demands in ways that would otherwise not be possible. For example, learn about spontaneous branches with darcs.

Convert Git Repo to Darcs

I would like to move a git repo I have to darcs. I have not been able to find docs or projects that explain how to do this; it looks like most users want to go the other way. In addition, being able to control a git repo from darcs would be cool to.

How to use the darcs library to query information about patches?

I want to write a Haskell program that queries information about a darcs repository. Instead of invoking the darcs executable and parse the results, I would rather use the darcs library directly. It is said to be "very much work in progress" and to…

Lightweight Continuous Integration for a centrally Haskell/Darcs toolchain?

I want some simple CI for a small dev setup. Two motivations -- a full build takes some time, and an anticipated testsuite will also take some time. I really would rather not dive headfirst into one of the big players that require a java application…
