Generates gource video out of multiple repositories.
#!/usr/bin/env bash
# Generates gource video (h.264) out of multiple repositories.
# Pass the repositories in command line arguments.
# Example:
# <this.sh> /path/to/repo1 /path/to/repo2
RESOLUTION="1600x1080"
outfile="gource.mp4"
i=0
for repo in $*; do
# 1. Generate a Gource custom log files for each repo. This can be facilitated by the --output-custom-log FILE option of Gource as of 0.29:
logfile="$(mktemp /tmp/gource.XXXXXX)"
gource --output-custom-log "${logfile}" ${repo}
# 2. If you want each repo to appear on a separate branch instead of merged onto each other (which might also look interesting), you can use a 'sed' regular expression to add an extra parent directory to the path of the files in each project:
sed -i -E "s#(.+)\|#\1|/${repo}#" ${logfile}
logs[$i]=$logfile
let i=$i+1
done
combined_log="$(mktemp /tmp/gource.XXXXXX)"
cat ${logs[@]} | sort -n > $combined_log
rm ${logs[@]}
echo "Committers:"
cat $combined_log | awk -F\| {'print $2'} | sort | uniq
