Repository files navigation



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.

Using Gource

gource [options] [path]


    -h, --help
            Help ('-H' for extended help).

            Set the viewport size. If -f is also supplied, will attempt to set
            the video mode to this also. Add ! to make the window non-resizable.

    --screen SCREEN
            Set the number of the screen to display on.

            Request a high DPI display when creating the window.

            On some platforms such as MacOS, the window resolution is specified in points instead of pixels.
            The --high-dpi flag may be required to access some higher resolutions.

            E.g. requesting a high DPI 800x600 window may produce a window that is 1600x1200 pixels.

    --window-position XxY
            Initial window position on your desktop which may be made up of
            multiple monitors.

            This will override the screen setting so don't specify both.

            Frameless window.

    -f, --fullscreen

    -w, --windowed

            Make the background transparent. Only really useful for screenshots.

    --start-date "YYYY-MM-DD hh:mm:ss +tz"
            Start with the first entry after the supplied date and optional time.

            If a time zone offset isn't specified the local time zone is used.

            Example accepted formats:

                "2012-06-30 12:00"
                "2012-06-30 12:00:00 +12"

    --stop-date "YYYY-MM-DD hh:mm:ss +tz"
            Stop after the last entry prior to the supplied date and optional time.

            Uses the same format as --start-date.

    -p, --start-position POSITION
            Begin at some position in the log (between 0.0 and 1.0 or 'random').

    -t, --stop-at-time SECONDS
            Stop (exit) after a specified number of seconds.

            Stop (exit) at the end of the log / stream.

            Loop back to the start of the log when the end is reached.

            Seconds to delay before looping.

    -a, --auto-skip-seconds SECONDS
            Skip to next entry if nothing happens for a number of seconds.

    -s, --seconds-per-day SECONDS
            Speed of simulation in seconds per day.

            Use the time of the last commit if the time of a commit is in the past.

    -c, --time-scale SCALE
            Change simulation time scale. This affects the movement speed of user avatars.

            E.g. 0.5 for half speed, 2 for double speed.

    -i, --file-idle-time SECONDS
            Time in seconds files remain idle before they are removed or 0
            for no limit.

        --file-idle-time-at-end SECONDS

            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 - An ISO 8601 or unix timestamp of when the update occurred.
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 - An ISO 8601 or 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:

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 time scale / user avatar movement speed
(+-)  Adjust simulation speed
(Keypad +-) Adjust camera zoom
(TAB) Cycle through visible users
(F12) Screenshot
(Alt+Enter) Fullscreen toggle
(ESC) Quit
