# Git filter to ignore lines in your files.

#
# 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.
set -eu
# Check if stdin is not tty and remove ignored lines from it.
