GitLens

GitLens supercharges the built-in Visual Studio Code Git capabilities. It helps you to visualize code authorship at a glance via inline Git blame annotations and code lens, seamlessly navigate and explore the history of a file or branch, gain valuable insights via powerful comparision commands, and so much more.

GitLens provides an unobtrusive blame annotation at the end of the selected line, a status bar item showing the commit author and date of the selected line, code lens showing the most recent commit and # of authors of the file and/or code block, and many commands for exploring commits and histories, comparing and navigating revisions, stash access, repository status, and more. GitLens is also highly customizable to meet your specific needs — find code lens intrusive or the selected line blame annotation distracting — no problem, it is easy to turn them off or change how they behave.

Previews

Featuring code lens, whole file inline blame annotations, and navigation and exploration via quick pick menus

Featuring selected line blame annotation and hovers, status bar commit details, quick pick menus, compare with previous, and more

Features

Git Blame Annotations

• Adds a blame annotation to the end of the selected line showing the commit id and message, with more details in a hover popup (optional, on by default)

  • Also adds a Show Blame Annotations command (gitlens.showBlame)

• Adds author and date blame information about the selected line to the status bar (optional, on by default)

  • By default clicking on the status bar shows a commit details quick pick menu with commands for comparing, navigating and exploring commits, and more

  • Provides customizable click behavior of the status bar — choose between one of the following

    • Toggle whole file blame annotations on and off
    • Toggle code lens on and off — only available if "gitlens.codeLens.visibility": "ondemand" is set

Known Issues

• If the Copy to * clipboard commands don't work on Linux -- xclip needs to be installed. You can install it via sudo apt-get install xclip
• Visible whitespace causes issues (vscode issue #11485) with the expanded and compact blame annotation styles when using a non-monospace font -- set "gitlens.advanced.toggleWhitespace.enabled": true if you are using a non-monospace font
