We recently launched a new source code browsing tool as part of Google Code’s project hosting feature. This new tool makes it easy to navigate through a project’s Subversion repository. Key features include: fast directory browsing tree, syntax highlighting, history of changes, and easy-to-read diffs. See it yourself under the “Source” tab of any project that we host.
The new system certainly feels fast, and uses jQuery to flip around in short order, jumping through the revisions of your system, expanding into new directories, etc.
This change required a change to my Google Code greasemonkey script that adds a direct link to the trunk. It now takes you right to the trunk of the code in the new browser!
