Today I present a new release of Momoko, version 0.3.0. It’s been a while ago since I released 0.2.0 (three months ago). I’ll blame on school and my vacation. ;)

The following changes have been made:

• Renamed momoko.Momoko to momoko.Client.
• Programming in blocking-style is now possible with AdispClient.
• Support for Python 3 has been added.
• The batch and chain fucntion now accepts different arguments. See the documentation for details.

The nicest addition is that you can now query the database without using callbacks. This is possible by using adisp. Here are some examples:

cursor = yield self.db.execute('SELECT 42, 12, 40, 11;')

cursors = yield self.db.batch({
    'query1': ['SELECT 42, 12, %s, %s;', (23, 56)],
    'query2': 'SELECT 1, 2, 3, 4, 5;',
    'query3': 'SELECT 465767, 4567, 3454;'
})

cursors = yield self.db.chain((
    ['SELECT 42, 12, %s, 11;', (23,)],
    'SELECT 1, 2, 3, 4, 5;'
))

As you can see there is a yield keyword. You also need to put an extra decorator on your get/post/somethingelse function, momoko.process. That’s all.

View the updated documentation on momoko.61924.nl and download the new release from PyPi.

Have fun.
