Repository visualization with Gource
As some of you already know, for the past 10 years I've been researching how to analyse, visualise and design collaborative processes and organizations. I started this research at Politecnico di Milano (MSc), then continued independently (openp2pdesign.org), and then started a doctorate at Aalto University (Doctor of Arts). The research is still going on, and the Fab Academy might be an interesting context for this as well.
At the moment, there are very few softwares for visualizing the process in a Git/Hg repository, and I will probably work on new visualization softwares soon, but it will take some time. Meanwhile, I used again Gource for visualizing the process in the repositories I worked with during this Fab Academy: Europe, and the Opendot + WeMake Fab Labs in Milan where I am the instructor. These videos were generated quite quickly, so they are not very refined at the moment, but they can give you an idea of what happened:
On Linux, you can download and compile Gource. On Mac, I installed Gource with:
brew install gource
...and Avconv, for rendering the video, with:
brew install libav
You can then export a log file from the repo, in order to use that for rendering the video:
gource --output-custom-log file.log
The basic usage of Gource is without avatars. There are few scripts around that download avatars from gravatar.com, I modified them in two scripts: one that get avatars also from GitHub, and another that get avatars from a Mercurial repo:
There are many many options for controlling Gource, here's my setup for creating the video and converting at the same time:
gource 1280x720 --user-image-dir ../FabAcademy2015-WeMake/.git/avatar/ gource --seconds-per-day 1 --stop-at-end --highlight-users --multi-sampling --output-ppm-stream --output-framerate 30 --title "Fab Academy 2015 - WeMake (Milan)" --hide mouse,filenames,progress wemake.log -o - | avconv -y -r 30 -f image2pipe -vcodec ppm -i - -b 65536K wemake.mp4
The EU repo is too big: too many files and users, so I changed a bit the settings:
gource 1280x720 --user-image-dir ../europe/.hg/avatar/ gource --seconds-per-day 1 --stop-at-end --highlight-users --multi-sampling --output-ppm-stream --output-framerate 30 --title "Fab Academy 2015 - Europe" --hide dirnames,bloom,mouse,filenames,progress eu.log -o - | avconv -y -r 30 -f image2pipe -vcodec ppm -i - -b 65536K europe.mp4</div>
