Visualization of perl development history

About 10 years ago I tried gource and made a visualization of the commit history of perl5.git. It was when grouce was new, shiny and cool:

10 years passed like a blink and it has been a remarkable decade for perl5.git. As we see the growth of commit volume, there is also stable pace of releasees thanks to the standardization of release procedure. With relocation of communication platform, participation and small fixes seems to be much easier. While it has not be a perfectly stable decade, it is a good one.

So as a 10-yearly review, here's the updated version of that gource visualization on perl5.git, all the way to mid 2021:

These are the commands used to produce that video:

cd ~/src/perl5
gource -s 0.01 --auto-skip-seconds 0.1 -r 30 -f --user-scale 3 --file-idle-time 0 --hide bloom,filenames,dirnames --date-format '%Y' -o ~/var/gource-perl.ppm
ffmpeg  -an -y -f image2pipe -vcodec ppm -i ~/var/gource-perl.ppm -r 30.000 ~/var/gource-out.webm
Enter fullscreen mode Exit fullscreen mode
