# SETUP:
|
|
#
|
|
# cp git-ignore-line.sh ~/bin/git-ignore-line
|
|
#
|
|
#
|
|
# USAGE:
|
|
#
|
|
# Mark single lines you want to ignore with 'GITIGNORE'. It ignores
|
|
# the whole line. It is recommended to be inside a comment in your code.
|
|
#
|
|
# Mark multiple lines surrounding them with 'GITIGNORE START' and
|
|
# 'GITIGNORE END'. It can not be nested.
|
|
#
|
|
# NOTE: Ignored lines might be lost on checkout.
|
|
#
|
|
#
|
|
# Add files to ignore:
|
|
#
|
|
# git ignore-line <pattern>
|
|
#
|
|
# Remove patterns with:
|
|
#
|
|
# git ignore-line -r <pattern>
|
|
#
|
|
# List configured patterns:
|
|
#
|
|
# git ignore-line -l
|
|
#
|
|
# PATTERN can be a file or a glob pattern: '*.html'. Remember to
|
|
# escape the `*`.
|
|
#

|
#
|
|
# TODO:
|
|
#
|
|
# - Stash the lines ignored by this filter before a git checkout.
