Have you heard about Subversion changelists<\/a>? \u00a0If you haven’t, chances are you aren’t utilizing your time properly. \u00a0Here is a brief introduction.<\/p>\n

Subversion 1.5 brings a new\u00a0changelists<\/em> feature that adds yet another method to the mix. Changelists are basically arbitrary labels (currently at most one per file) applied to working copy files for the express purpose of associating multiple files together. Users of many of Google’s software offerings are familiar with this concept already. For example,\u00a0Gmail<\/a> doesn’t provide the traditional folders-based email organization mechanism. In Gmail, you apply arbitrary labels to emails, and multiple emails can be said to be part of the same group if they happen to share a particular label. Viewing only a group of similarly labeled emails then becomes a simple user interface trick. Many other Web 2.0 sites have similar mechanisms\u2014consider the \u201ctags\u201d used by sites such as\u00a0YouTube<\/a> and\u00a0Flickr<\/a>, \u201ccategories\u201d applied to blog posts, and so on. Folks understand today that organization of data is critical, but that how that data is organized needs to be a flexible concept. The old files-and-folders paradigm is too rigid for some applications.<\/p><\/blockquote>\n

As wonderful as they are, changelists do have some limitations.<\/p>\n

Subversion’s changelist feature is a handy tool for grouping working copy files, but it does have a few limitations. Changelists are artifacts of a particular working copy, which means that changelist assignments cannot be propagated to the repository or otherwise shared with other users. Changelists can be assigned only to files\u2014Subversion doesn’t currently support the use of changelists with directories. Finally, you can have at most one changelist assignment on a given working copy file. Here is where the blog post category and photo service tag analogies break down\u2014if you find yourself needing to assign a file to multiple changelists, you’re out of luck.<\/p><\/blockquote>\n

But even with this limitations, changelists are extremely handy. \u00a0So I urge you once again to read the book<\/a>. \u00a0 Or just the changelists section<\/a>.<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n
