VSCode offers two primary views for comparing files: side-by-side and inline. The side-by-side view displays the two files next to each other, while the inline view shows the changes within a single file.

The side-by-side view is useful for quickly identifying the overall structure of the changes. It allows you to see the two files at a glance and understand how they differ. The inline view, on the other hand, is useful for focusing on the specific changes made within the code. It shows the added and removed lines within the same file, making it easier to understand the context of the changes.

To switch between these views, you can use the “View: Toggle Inline Diff” command in VSCode. This command toggles between the side-by-side and inline views, allowing you to choose the view that best suits your needs.

5.2. Ignoring Whitespace

Whitespace differences can often clutter the diff view and make it difficult to focus on meaningful changes. VSCode allows you to ignore whitespace differences, making the comparison more accurate and efficient.

To ignore whitespace differences, you can use the “Diff: Ignore Trim Whitespace” command in VSCode. This command ignores whitespace at the beginning and end of lines, reducing the clutter in the diff view. You can also use the “Diff: Ignore All Whitespace” command to ignore all whitespace differences, including spaces, tabs, and line breaks.

Ignoring whitespace differences can significantly improve the accuracy and efficiency of the comparison process, especially when working with code that has inconsistent formatting.

5.3. Highlighting Differences

VSCode allows you to customize the way differences are highlighted in the diff view. You can adjust the colors and styles used to indicate added, removed, and modified lines, making the comparison more visually appealing and easier to understand.

To customize the highlighting, you can use the “workbench.colorCustomizations” setting in VSCode. This setting allows you to specify the colors and styles used for various elements of the VSCode interface, including the diff view.

For example, you can change the color used to indicate added lines to green, and the color used to indicate removed lines to red. You can also change the style used to highlight modified lines, such as using a different background color or font style.
