I would like to start using version control when developing client sites in wordpress. Anyone recommend a good choice? It seems the main contenders for me are Subversion and Mercurial.
Most of my work is done on my own, however I might involve someone else on some projects in the future.
Subversion, Mercurial and Git are popular right now. Just choose whichever one you like best.
Git is nice since Github is free for open source projects.
Subversion is free as well.
You might have more luck finding subversion support in IDEs since it’s been around longer. From what I understand about Git, GUIs are still in development for it.
I recommend you try Dynamsoft SourceAnywhere, a SQL-server based source control solution. It’s easy to use and set up, especially if you are familiar with SourceSafe. Both standalone and hosted editions are available.
Subversion is the most popular CVS system as far as I know. But you can also try git… it allows you to publish your code, documentation, wiki etc on Github.com where anyone who’s interested can search/browse/download your code or request to contribute.
