When submitting a code review, you can look at a diff of the file(s) to see what changes have been made since your last commit. To see the diff, you must first configure the Klocwork plug-in to use your preferred diff tool.

Prerequisites:

The Klocwork Server must be running
Your SCM must be integrated and you must have a cloned SCM repository on local storage
An external diff tool must be installed on your local machine

To configure your diff tool with Visual Studio:

Go to Klocwork > Options > Klocwork > General.
Click the Diff Viewer tab.
In the Command field, browse to the path of your diff tool. For example, C:\Program Files (x86)\WinMerge\WinMergeU.exe.
OPTIONAL: If your diff tool requires additional macros for the original file and modified file, add them to the Arguments field. If no arguments are provided, it uses "$(BasePath)" "$(ItemPath)" as the defaults.

Note: The file path may contain spaces, so it's good practice to include quotes around the macros when defining the arguments.

Viewing the diff from Visual Studio

To view the diff for your code review, right-click the file and open the Create Code Review dialog. In the Changes field, click on a node and select Diff.

Tip: You can also right-click and select Diff file or double-click on a node to view the diff.

The diff tool you configured with Visual Studio will open showing you the original file and the modified file.

Note: If the node you are trying to view has any associated children nodes, all of them will be diffed.
