Gource - a software version control visualization


gource [options] [path]


gource is an OpenGL-based 3D visualisation 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 requires a OpenGL capable video card to run.


−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.


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 12:00:00 +12"

−−stop−date "YYYY−MM−DD hh:mm:ss +tz"

Stop at 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’).

−−stop−position POSITION

Stop (exit) at some position in the log (does not work with STDIN).

−−path 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 will 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

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 - Single character 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 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
