# Check for "DELME" in commit messages of about-to-be-pushed commits

####################################################################
|
|
# This hook script is triggered by `git push` right after a connection to the remote
|
|
# was established and its initial response was received, and right before generating
|
|
# and pushing a pack-file.
|
|
# The operation will be aborted when exiting with a non-zero status.
|
|
#
|
|
# The following arguments are provided:
|
|
#
|
|
# $1 - The symbolic name of the remote to push to, like "origin" or the URL like "https://github.com/GitoxideLabs/gitoxide" if there is no such name.
|
|
# $2 - The URL of the remote to push to, like "https://github.com/GitoxideLabs/gitoxide".
|
|
#
|
|
# The hook should then read from standard input in a line-by-line fashion and split the following space-separated fields:
|
|
#
|
|
# * local ref - the left side of a ref-spec, i.e. "local" of the "local:refs/heads/remote" ref-spec
|
|
# * local hash - the hash of the commit pointed to by `local ref`
|
|
# * remote ref - the right side of a ref-spec, i.e. "refs/heads/remote" of the "local:refs/heads/remote" ref-spec
|
|
# * remote hash - the hash of the commit pointed to by `remote ref`
|
|
#
|
|
# In this example, we abort the push if any of the about-to-be-pushed commits have "DELME" in their commit message.
|
|
#
|
|
# To enable this hook remove the `.sample` suffix from this file entirely.
