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.


Set the window size. If -f is also supplied, will attempt to set the video mode to this also.
-p, --start-position POSITION
Begin at some position in the log (between 0.0 and 1.0).
--stop-position POSITION
Stop (exit) at some position in the log (does not work with STDIN).
Stop on break in activity. May be combined with --stop-position.
Stop (exit) at the end of the log / stream.
Loop back to the start of the log when the end is reached.
-a, --auto-skip-seconds SECONDS
Automatically skip to next entry if nothing happens for a specified number of seconds.
-s, --seconds-per-day SECONDS
Speed of simulation in seconds per day.
Realtime playback speed.
-i, --file-idle-time SECONDS
Time in seconds files remain idle before they are removed.
-e, --elasticity FLOAT
Elasticity of nodes.
-b, --background FFFFFF
Background colour in hex.
--date-format FORMAT
Specify display date string (strftime format).
--log-format FORMAT
Specify format of the log being read (git,cvs,custom). Required when reading STDIN.
Get the git log of a branch other than the current one.
Print the git log command used by gource.
Print the hg log command (Mercurial) used by gource.
Print the cvs-exp.pl log command used by gource.
--follow-user USER
Have the camera automatically follow a particular user.
--highlight-user USER
Highlight the names of a particular user.
Highlight the names of all users.
--file-filter REGEX
Filter out any files matching a specified regular expression.
--user-image-dir DIRECTORY
Directory containing .jpg or .png images of users (eg 'Full Name.png') to use as avatars.
--default-user-image IMAGE
Path of .jpg to use as the default user image.
Colourize user images.
--crop AXIS
Crop view on an axis (vertical,horizontal).
Enable multi-sampling.
--bloom-multiplier FLOAT
Adjust the amount of bloom.
--bloom-intensity FLOAT
Adjust the intensity of the bloom.
Disable progress bar.
Disable bloom effect.
Set the maximum number of files. Excess files will be discarded.
--max-file-lag SECONDS
Max time files of a commit can take to appear.
--max-user-speed UNITS
Max speed users can travel per second.
--user-friction SECONDS
Time users come to a complete hault.
--user-scale SCALE
Change scale of users.
Hide users.
Hide tree.
Hide files.
Hide usernames.
Hide filenames.
Hide directory names.
Hide the date.
--output-ppm-stream FILE
Write frames as PPM to a file ('-' for STDOUT).
--output-framerate FPS
Framerate of output (used with --output-ppm-stream).
Either a Git or Mercurial directory, a pre-generated log file (see --git-log-command, --hg-log-command or the custom log format) or '-' to read STDIN. If path is ommited gource will attempt to read a log from the current directory.


View the log of the respository in the current path:


View the log of a project in the specified directory:

           gource my-project-dir

Save a copy of the log using in a special log format and play it back (example is for Git, Mercurial users see --hg-log-command):

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

NOTE: --git-log-command assumes you have a recent version of git that supports all the options. You may need to modify the command line to work with an older version (changing %aN to %an for instance).


The Gource homepage has guides and examples for using Gource with other version control systems:

           CVS - http://code.google.com/p/gource/wiki/CVS
           SVN - http://code.google.com/p/gource/wiki/SVN


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 - 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.


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/unpause 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 V key.

Interactive keyboard commands:

           (V) Toggle camera mode
           (C) Displays Gource logo
           (N) Jump forward in time to next log entry.
           (+-) Adjust simulation speed.
           (<>) Adjust time scale.
           (TAB) Cycle through visible users
           (ESC) Quit
