# script to extract commit author's name from standard input. The
|
||
|
|
# input should be <AUTHOR>:<EMAIL>, one per line.
|
||
|
|
# This script expects the input is created by git-log command:
|
||
|
|
#
|
||
|
|
# git log --format=%aN:%aE
|
||
|
|
#
|
||
|
|
# This script removes duplicates based on email address, breaking a
|
||
|
|
# tie with longer author name. Among the all author names extract the
|
||
|
|
# previous step, we remove duplicate by case-insensitive match.
|
||
|
|
#
|
||
|
|
# So we can do this in one line:
|
||
|
|
#
|
||
|
|
# git log --format=%aN:%aE | sort | uniq | ./author.py > authors
