tmux shortcuts & cheatsheet

start new:

tmux

start new with session name:

tmux new -s myname

(C-x means ctrl+x, M-x means alt+x)

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

	def truncate_db(engine):
	# delete all table data (but keep tables)
	# we do cleanup before test 'cause if previous test errored,
	# DB can contain dust
	meta = MetaData(bind=engine, reflect=True)
	con = engine.connect()
	trans = con.begin()
	con.execute('SET FOREIGN_KEY_CHECKS = 0;')
	for table in meta.sorted_tables:
	con.execute(table.delete())

	from sqlalchemy import create_engine, event, orm
	from sqlalchemy.orm import sessionmaker
	from sqlalchemy.orm.session import Session as SessionBase, object_session
	from sqlalchemy.event.api import listen

	# The following adds delete, insert, and update events after successful commits.
	# SQLAlchemy provides only events after flushes, but not after commits.
	# The classes are adapted from Flask-SQLAlchemy.
