# Sublime's HTML reindenting is currently pretty bad. And Tidy and xmllint
# change my code in ways I don't really like or need. I just need the thing
# reindented sanely. Emacs did that pretty well.
#
# One thing led to another. A few drinks later and now I'm using Emacs to
# reindent HTML from within Sublime.

# Save the contents of this file as ohmygodemacs.py in your User directory.
# Then save the contents of the following docstring as ohmygodemacs.elsip in your
# User directory

# Then bind this command to a keystroke, e.g. "ctrl-alt-x" by adding
# this to your user keymap:
#
# { "keys": ["ctrl+alt+x"], "command": "emacs_reindent" },
#
# Or execute it from the console:
#
# view.run_command('emacs_reindent')
