Investigate changes in Git repository
In DataGrip, you can trace back all changes in your attached directory. This helps you locate the author of any change, review the differences between file versions or commits, and safely roll back and undo changes if necessary.
Review the attached directory history
You can review all changes made to the attached directory that match the specified filters. To view attached directory history, open the Log tab of the Git tool window Alt+9. It shows all changes committed to all branches and remote repositories:
Navigate and search through attached directory history
Search through the list of commits by entering full commit names or messages or their fragments, revision numbers, or regular expressions.
Filter the commits by branch or favorite branches, user, date, and folder (or root and folder for multi-root projects).
Click the Go to Hash/Branch/Tag icon on the toolbar or press Ctrl+F and specify a commit hash, tag or the name of a branch you want to jump to (you will be taken to the latest commit in that branch).
Press the Left and Right keys to jump to the parent/child commit. This is especially useful if you have commits to different repositories and multiple branches all mixed in the Log tab of the Git tool window Alt+9.
For more details on the Log tab of the Git tool window Alt+9, see Log tab.
Review an attached directory's snapshot at a specific revision
DataGrip lets you review the state of your attached directory at a selected revision.
Open the Git tool window Alt+9 and switch to the Log tab.
Select a commit and choose Show Repository at Revision from the context menu.
The Repositories tool window will open containing the snapshot of your attached directory at the selected revision.
Review the differences between two commits
DataGrip allows you to check which files were modified between two commits instead of having to browse the changes in each commit in between.
Select any two commits in the Log tab of the Git tool window Alt+9 and choose Compare Versions from the context menu.
The Changes tool window with a list of files modified between the selected commits opens. You can view the diff for any file by clicking or pressing Ctrl+D.
Review file history
You can review all changes made to a specific file, and find what exactly was modified in each revision.
Select the required file in any view (in the Files tool window, in the editor, in the Local Changes view, and so on).
Select Git | Show History from the main VCS menu or from the context menu of the selection. The History tab is added to the Git tool window showing the history for the selected file and allowing you to review and compare its revisions.
To identify which changes were introduced in a specific revision, select it in the list. On the right side of the panel the diff is instantly shown.
To view the diff of the whole file in the dedicated diff viewer, select it in the list and press Ctrl+D or click the button on the toolbar. The Differences Viewer will open showing what has changed in this revision.
Review history for directories
In addition to reviewing the history for the whole attached directory or for a specific file, you can check which changes were made in specific folders.
Select a directory or multiple directories in the Files tool window and choosefrom the context menu.
A new tab is added to the Git tool window Alt+9 that shows commits filtered by the selected folders.
Review the differences between the local and a committed file version
You can check how a committed file revision is different from its local version:
Open the Git tool window Alt+9 and switch to the Log tab.
Select the commit you are interested in, and in the right pane select the file.
Click the button on the toolbar.
Review how changes were merged
In the Log tab of the Git tool window Alt+9, select the merge commit you are interested in.
If no conflicts were detected and resolved during the merge, DataGrip will display the corresponding message in the Changed Files pane and suggest reviewing changes that originate from both parents:
Select the required file from one of the nodes and click the Show Diff icon on the toolbar or press Ctrl+D. The Differences Viewer will show a two-panel diff allowing you to compare the current version with the selected parent.
If conflicts occurred during the merge, the Changed Files pane will show you a list of files merged with conflicts.
Select the required file and click the Show Diff icon on the toolbar or press Ctrl+D. The Differences Viewer will show a three-panel diff allowing you to compare the current version with each of its parents, and see how exactly conflicts were resolved.
Locate code author (Annotate with Git Blame)
You can figure out who introduced which changes to a file by using VCS annotations (corresponds to git-blame). The annotated view shows detailed information for each line of code:
Annotations for lines modified in the current revision are marked with a bold type and an asterisk.
By default, different commits are highlighted with different colors (see Configure the amount of information shown in annotations).
From the annotations view, you can jump to:
The corresponding commit in the Log tab of the Git tool window Alt+9: click the annotation or hover the cursor over it and click the commit hash in the popup with detailed info.
The difference in lines: hover the cursor over an annotation. The IDE will highlight the line and the changes from the corresponding commit.
The corresponding commit on https://github.com: use the Open on GitHub context-menu option.
The related issue in your bug-tracking system if issue navigation is enabled: hover the cursor over an annotation and click the issue link if it's included in the commit message
Right-click the gutter in the editor or in the Differences Viewer and select Annotate with Git Blame from the context menu.
You can assign a custom shortcut to the Annotate command: go to the Keymap page of the IDE settings Ctrl+Alt+S and look for Version Control Systems | Git | Annotate.
Configure the amount of information shown in annotations
You can choose how much information you want to see in the annotations view.
Right-click the annotations gutter, choose View and select which type of information you want to see, including the revision from which this change originated, the date, the name of the author in different formats, and the commit number.
You can also set highlighting under Colors.
Configure annotation options
Right-click the annotations gutter and select Options from the context menu:
Ignore Whitespaces: whitespaces will be ignored (git
blame -w). This means that annotations will point to the previous meaningful commit.
Detect Movements Within File: when a commit moves or copies lines within the same file, such change will be ignored (git
blame -M). This means that annotations will point to the previous meaningful commit.
Detect Movements Across Files: when a commit moves or copies lines from other files that were modified in the same commit, such change will be ignored (git
blame -C). This means that annotations will point to the previous meaningful commit.
Show Commit Timestamp: select this option if you want DataGrip to show the commit timestamp in the Annotations view instead of the time when a change was authored.
Customize date format
Press Ctrl+Alt+S to open the IDE settings and select.
Click the Date Time Pattern field next to VCS Annotate and specify the date format that you want to use for VCS annotations. See patterns reference.
Annotate a previous revision
DataGrip lets you annotate not only the current file revision, but also its previous revisions. The following options are available from the context menu of the annotations gutter:
Annotate Revision: this option is useful if you want to check what a file looked like after a particular change was committed.
Annotate Previous Revision: this option is useful if you find yourself in a situation when the last change in a particular line is meaningless, for example, if all that was changed is code formatting. In this case, you can check what the previous revision of the file looked like.
Hide Revision: this option is useful to avoid seeing irrelevant or administrative changes. These are typically introduced by low-level migrations or formatting actions. When these changes affect the whole root they create a lot of clutter in the "Annotate" dialog and so it may be desirable to exclude the changes from the view as well as from the ‘annotate’ column. The "Hide Revision" action allows you to exclude a revision from the annotation result in-place and show the result in both the editor and gutter. The excluded revisions can be restored with the opposite action "Restore Hidden Revisions". Information about hidden revisions is displayed in the notification panel at the top of the editor. It is also possible to restore hidden revisions by clicking on the corresponding link in the notification panel.
You can also annotate a particular file from the History view. In the History tab, select the file version you want to review, right-click the corresponding line and select Annotate from the context menu.
