gource - Online in the Cloud

PROGRAM:

NAME

Gource - a software version control visualization

SYNOPSIS

gource <options> <path>

DESCRIPTION

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.

REQUIREMENTS

gource requires a OpenGL capable video card to run.

OPTIONS

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

-WIDTHxHEIGHT, --viewport WIDTHxHEIGHT
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.

Disable automatic camera rotation.

--hide DISPLAY_ELEMENT
Hide one or more display elements from the list below:

files - file icons
filenames - names of files
mouse - mouse cursor
progress - progress bar widget
root - root directory of the tree
tree - animated tree structure

--load-config CONFIG_FILE
Load a config file.

--save-config CONFIG_FILE
Save a config file with the current options.

--path 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:

gource

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

INTERFACE

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
(+-) Adjust simulation speed
(<>) Adjust time scale
(TAB) Cycle through visible users
(F12) Screenshot
(Alt+Enter) Fullscreen toggle
(ESC) Quit
