|
|
Script to filter the git log for commits whose author's e-mail is
|
|
_not_ on @lyx.org. It's intended to be used by a CI job.
|
|
|
|
This script can be used to check that the LyX developers have
|
|
correctly configured their git to provide an e-mail address that's in
|
|
the @lyx.org domain. This is needed for proper functioning of the
|
|
e-mails being automatically sent to lyx-cvs@lyx.org.
|
|
|
|
Syntax:
|
|
<SCRIPT> { --help | -h | --list | -l | --compute-hash }
|
|
<SCRIPT> { --check-hash | -c } <EXPECTED-HASH>
|
|
|
|
Examples:
|
|
# Show this help text
|
|
<SCRIPT> -h
|
|
|
|
# List contributions from non-@lyx.org-addresses since 2015-01-01
|
|
<SCRIPT> --list
|
|
|
|
# Compute hash (SHA-512) of list of contributors
|
|
<SCRIPT> --compute-hash
|
|
|
|
# Check hash of list of contributors against expected hash.
|
|
# This scripts exist with a non-zero error code if hash does not match.
