Differences viewer for files
This dialog is displayed when you compare two files or two versions of a file (local changes or changes between local files and their revisions in a remote repository). You can compare files of any types, including binaries and .jar files. To open the dialog, select two files to compare or a file to compare its versions and press Ctrl+D.
The differences viewer provides a powerful editor that enables code completion, live templates, and other features.
Diff & Merge viewer
|Item||Tooltip and Shortcut||Description|
|/||Previous Difference / Next Difference Shift+F7 F7|
Jump to the next or previous difference.
When the last or first difference is reached, PhpStorm suggests to click the arrow buttons F7/ Shift+F7 once more and compare other files, depending on the Go to the next file after reaching last change option in the Differences Viewer settings.
This behavior is supported only when the Differences Viewer is invoked from the Commit tool window Alt+0.
|Compare Previous/Next File |
Compare the local copy of the previous or next file with its update from the server.
|Go To Changed File Ctrl+N||Display all the changed files in the current change set and navigate to them. This button is available only when you review changes in multiple files. For example, in the Local Changes view.|
|Jump to Source |
|Open the selected file in the active pane in the editor. The caret is placed in the same position as in the Differences Viewer.|
Select a viewer mode: side-by-side or unified. The side-by-side mode has two panels, the unified mode has one panel.
You can edit code and perform Apply, 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.
Define how the differences viewer should treat whitespaces.
Select the way differences granularity is highlighted.
The available options are:
|Collapse unchanged fragments||Collapse all the unchanged fragments in both files. The amount of non-collapsible unchanged lines is configurable in the Diff & Merge settings page. To open the Diff & Merge page, open settings by pressing Ctrl+Alt+S and navigate to .|
|Synchronize scrolling||Click this button to scroll both differences panes simultaneously. If this button is released, each of the panes can be scrolled independently.|
Open a list of available settings.
These commands are also available from the context menu of the differences viewer gutter.
|Include into commit Alt+I|
This checkbox only appears if you invoke the Differences Viewer from the Commit Changes dialog with multiple changed files (all of which are deselected), and you explore the differences between them and hit the last difference in a file.
Select this checkbox if you want to include the file you've reviewed into the commit.
|Help F1||Open a browser and show the corresponding help page.|
|Ctrl+Tab||Switch between the panes of the differences viewer. The active pane has the cursor.|
Apply differences between panes (in case of the side-by-side viewer) or between lines (in case of the unified viewer).
The chevron buttons can change their behavior:
Click this icon to invoke the list of options allowing you to compare different versions of a file to resolve a conflict.Note that Base refers to the file version that the local and the repository versions originated from (initially displayed in the middle pane), while Middle refers to the resulting version.
|Apply All Non-Conflicting Changes||Click this button to apply all non-conflicting changes. You can also make this behavior automatic, by selecting the checkbox Automatically apply non-conflicting changes in the Diff & Merge page of the Settings/Preferences dialog.|
|Apply Non-Conflicting Changes from the Left/Right Side||Click these buttons to merge non-conflicting changes from the left/right parts of the dialog.|
|Annotate with GitBlame|
This option is only available from the context menu of the gutter.
Use this option to explore who introduced which changes to the repository version of the file, and when. The annotations view lets you see detailed information for each line of code, such as the version from which this line originated, the ID of the user who committed this line, and the commit date.
For more details on annotations, refer to VCS annotations.
