Flicking Between File Revisions

With the upcoming release of PureCM 2012/1, I expect you will hear a lot about the new web client and performance improvements. But as a developer it is the file history differences window which I am most excited about.

The file history dialog has been redesigned with a tab view at the bottom. The tab view displays contextual information about the selected revision. Initially the Description tab will be selected – showing the changeset description for the selected revision.

Things get interesting when you select the Differences tab. This displays the familiar differences tool showing the changes made in that revision.

So you can quickly switch between revisions of a file to view the changes. This becomes very useful if a file has been changed many times and you are trying to isolate when or why some code was changed.

Note that the File History Dialog will need to be large to show the differences. If the File History Dialog is docked then you can right-click the tab and select ‘Float’ to make more room.

The Annotated History can be used for a similar purpose – but the Annotated History only shows when a line was last changed. Maybe the line was changed in a later revision but this change is not interesting to you? Or maybe you do know exactly which line has been changed? Maybe you know that the file has changed at some point and want to know what the exact changes were.

If you are very perceptive you might have also noticed that there is a new ‘Move to First Difference’ option at the top. If this is selected then when you move to a new revision the Differences tab will automatically select the first difference. This is what you want if you are browsing the changes made to a file. If this is not selected then the Differences tab will stay at the same line when switching revisions. This is what you want if you are looking for changes to a particular line.

You will be glad to hear that the Differences tab works for image files in the same way. It also works for Word and Excel files if they have been setup for xml post-processing.
