TortoiseGit Manual
Sometimes you need to know not only what lines have changed, but also who exactly changed specific lines in a file. That's when the → command, sometimes also referred to as annotate command comes in handy.
This command lists, for every line in a file, the author and the revision the line was changed.
By default the blame file is viewed using TortoiseGitBlame, which highlights the different revisions to make it easier to read.
TortoiseGitBlame, which is included with TortoiseGit. When you hover the mouse over a line in the blame info column, all lines with the same revision are shown with a darker background. Lines from other revisions which were changed by the same author are shown with a light background. The coloring may not work as clearly if you have your display set to 256 color mode.
If you left click on a line (on the blame info column on the left), all lines with the same revision are highlighted, and lines from other revisions by the same author are highlighted in a lighter color. This highlighting is sticky, allowing you to move the mouse without losing the highlights. Click on that revision again to turn off highlighting.
The revision comments (log message) are shown in a hint box whenever the mouse hovers over the blame info column. If you want to copy the log message for that revision, use the context menu which appears when you right click on the blame info column.
If you need a better visual indicator of where the oldest and newest changes are, select → . Then the background color intensity of the lines is related to its age. This will use a color gradient to show newer lines in yellow and older lines in white. The default coloring is quite light, but you can change it using the TortoiseGitBlame settings.
Please also check out the menu. There you can toggle the and also toggle the detection of moved/copied lines from other files and .
You can search within the Blame report using → . This allows you to search for revision numbers, authors and the content of the file itself. Log messages are not included in the search - you should use the Log Dialog to search those.
You can also jump to a specific line number using → .
When the mouse is over the blame info columns, a context menu is available which helps with comparing revisions and examining history, using the commit of the line under the mouse as a reference. → generates a blame report for the same file, but using the previous revision as the upper limit. This gives you the blame report for the state of the file just before the line you are looking at was last changed. → starts your diff viewer, showing you what changed in the referenced revision of the file. Please note, however, that these two options are only available if this line is not there since the initial commit of the file. → displays the revision log dialog starting with the referenced revision.
The settings for TortoiseGitBlame can be accessed using → on the TortoiseGitBlame tab. Refer to the section called “TortoiseGitBlame Settings”.
