Contributors list



Gource is a visualization tool for source control repositories.

The repository is displayed as a tree where the root of the repository is the centre, directories are branches and files are leaves. Contributors to the source code appear and disappear as they contribute to specific files and directories.


Gource's display is rendered using OpenGL and requires a 3D accelerated video card to run.

path    Either a supported version control directory, a pre-generated log
        file (see log commands or the custom log format), a Gource conf
        file or '-' to read STDIN.

        If path is omitted, gource will attempt to read a log from the
        current directory.

Git, Bazaar, Mercurial and SVN Examples:

View the log of the repository in the current path:


View the log of a project in the specified directory:

    gource my-project-dir

For large projects, generating a log of the project history may take a long time. For centralized VCS like SVN, generating the log may also put load on the central VCS server.

In these cases, you may like to save a copy of the log for later use.

You can generate a log in the VCS specific log format using the --log-command VCS option:

    cd my-svn-project
    `gource --log-command svn` > my-svn-project.log
    gource my-svn-project.log

You can also have Gource write a copy of the log file in its own format:

    gource --output-custom-log my-project-custom.log

CVS Support:

Use 'cvs2cl' to generate the log and then pass it to Gource:

    cvs2cl --chrono --stdout --xml -g-q > my-cvs-project.log
    gource my-cvs-project.log

Custom Log Format:

If you want to use Gource with something other than the supported systems, there is a pipe ('|') delimited custom log format:

timestamp - A unix timestamp of when the update occured.
username  - The name of the user who made the update.
type      - initial for the update type - (A)dded, (M)odified or (D)eleted.
file      - Path of the file updated.
colour    - A colour for the file in hex (FFFFFF) format. Optional.

Caption Log Format:

Gource can display captions along the timeline by specifying a caption file (using --caption-file) in the pipe ('|') delimited format below:

timestamp - A unix timestamp of when to display the caption.
caption   - The caption

Recording Videos:

See the guide on the homepage for examples of recording videos with Gource:

More Information:

Visit the Gource homepage for guides and examples of using Gource with various version control systems:


The time shown in the top left of the screen is set initially from the first log entry read and is incremented according to the simulation speed (--seconds-per-day).

Pressing SPACE at any time will pause/resume the simulation. While paused you may use the mouse to inspect the detail of individual files and users.

TAB cycles through selecting the current visible users.

The camera mode, either tracking activity or showing the entire code tree, can be toggled using the Middle mouse button.

You can drag the left mouse button to manually control the camera. The right mouse button rotates the view.

Interactive keyboard commands:

(V)   Toggle camera mode
(C)   Displays Gource logo
(K)   Toggle file extension key
(M)   Toggle mouse visibility
(N)   Jump forward in time to next log entry
(S)   Randomize colours
(D)   Toggle directory name display mode
(F)   Toggle file name display mode
(U)   Toggle user name display mode
(G)   Toggle display of users
(T)   Toggle display of directory tree edges
(R)   Toggle display of root directory edges
(+-)  Adjust simulation speed
(<>)  Adjust time scale
(TAB) Cycle through visible users
(F12) Screenshot
(Alt+Enter) Fullscreen toggle
(ESC) Quit
