Hi!


Short question up front: what exactly should be in the proposed
factory class? What does it take? What does it return?

Second question: what should NMEASentence attributes look like?
Properties? There are some proposed things in t.p.nmea in trunk.


Also, progress report:
    - NMEAAdapters now correctly fire callbacks on receivers. There
are tests that show this working for multiple sentences.
    - NMEA date support. You now get callbacks with date and time.

New things can be found in trunk at the usual places (launchpad).

Work in progress:
    - satellite information support (this is hairy because unlike
other sentences, the *same* fields are across multiple sentences :/)
    - error support (this is hairy because the subset of NMEA that
everyone supports essentially has no useful information about this)

Basically error support is a lot of work but boring, satellite support
is not so much work but hairy and disgusting NMEA internals handling.

I'm working on error support first because it's still early in the morning.


thanks for listening
Laurens
