Differences pane

Diff viewer

Item	Tooltip and Shortcut	Description
/	Previous Difference / Next Difference `ShiftF7` `F7`	Jump to the next or previous difference. When the last or the first difference is reached, GoLand suggests clicking the arrow buttons or pressing `F7`/`ShiftF7` once more and comparing other files modified locally. This behavior depends on the Go to the next file after reaching last change option in the Diff Viewer settings.
	Compare Previous/Next File `Alt0←Alt0→`	Compare the local copy of the previous or next file with its update from the server. note These controls are only available if more than one file has been modified locally.
	Go To Changed File `Ctrl0N`	Display all changed files in the current change set and navigate to them. This action is only available when you review changes to multiple files.
	Jump to Source `F4`	Open the selected file in the editor. The caret is placed in the same position as in the Diff Viewer.
Viewers		Select a viewer mode: side-by-side or unified. The side-by-side mode has two panels, and the unified mode has one panel. You can edit code and perform the Accept, Append, Revert actions in both viewers. You can change text only in the right-hand part of the side-by-side viewer or in the lower line in the unified viewer. You can edit only local versions of your files. You cannot edit files that have read-only status.
Whitespace		Define how the Diff Viewer should treat whitespaces. Do not ignore: white spaces are important, and all the differences are highlighted. This option is selected by default. Trim whitespaces: trim whitespaces if they appear in the end and at the beginning of a line (`("\t", " ")`). If two lines differ in trailing whitespaces only, these lines are considered equal. If two lines are different, trailing whitespaces are not highlighted in the By word mode. Ignore whitespaces: white spaces are not important, regardless of their location in the source code. Ignore whitespaces and empty lines: ignores whitespaces and empty lines. The following entities are ignored: all whitespaces (as in the 'Ignore whitespaces' option) all added or removed lines consisting of whitespaces only all changes consisting of splitting or joining lines without changes to non-whitespace parts. For example, differences between `a b c` and `a \n b c` are not highlighted in this mode.
Highlighting mode		Select the way differences granularity is highlighted. The available options are: Highlight words: modified words are highlighted Highlight lines: modified lines are highlighted Highlight split changes: if this option is selected, big changes are split into smaller changes. For example, `A \n B` and `A X \n B X` are treated as two changes instead of one. Highlight characters: modified symbols are highlighted Do not highlight: if this option is selected, the differences are not highlighted at all. Use the Do not highlight option when you work with the files that were significantly modified. In such cases, highlighting might introduce additional difficulties during a review.
	Collapse Unchanged Fragments	Collapse all the unchanged fragments in both files. The amount of non-collapsible unchanged lines is configurable on the Diff & Merge settings page. To open the Diff & Merge page, open settings by pressing `CtrlAlt0S` and navigate to Tools \| Diff & Merge. .
	Synchronize Scrolling	Click this button to scroll both differences panes simultaneously. If this button is released, each of the panes can be scrolled independently.
	Settings	Open a list of available settings. These commands are also available from the context menu of the Diff Viewer gutter.
	Show diff in external tool	Invoke an external diff viewer specified on the External Diff Tools settings page. This button is available only on the toolbar when the Use external diff tool option is enabled on the External Diff Tools settings page.
	Help `F1`	Open a browser and show the corresponding help page.
