# Git Change Indication (overriding default omz function)
#
# !!ONLY USE WITH MULTILINE PROMPTS!! as there can be a lot of symbols
# (perhaps should limit to 20 or something)
#
# Prints symbol for each change instead of just indicating if a type exists.
# This gives a better visual sense of how much has changed.
#
# TODO If you find prompt speed slow, it's because of this section.
# The limitation is the speed of `git status` in any given repo (it's slower
# than you'd imagine). The rest of the symbol computation is pretty much
# instantaneous, even on older CPUs.
# TODO should we make a way to toggle this on/off on the fly, to deal with
# performance issues for ridiculous git repos?
# TODO number of changes in git repo doesn't necessarily mean slow `git status`,
# neither does it seem to definitely be caused by large number of files. When is
# `git status` slow?
