# 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') | |
