Re: EPICS Python??

[Matthieu Bec <mbec@gemini.edu>]

Hi,
similarly I keep a less publicized python/CA module since 1999, mainly 
stemming from personal interest in developing python extensions. The 
module has built in help and features I found usefull and created as I 
needed to interface with Epics systems
- ca_preemptive_callbacks is configurable at startup: GTK/Glade UI 
seemed to better integrate a non threaded model, while shell/curses 
tools work nicely using the python interpreter lock and threads.
- 'one shot' CA put/get
- 'long lived' pv channels as python objects
Support is limited to put/get/monitor.

there are no sites for download but I can share this `yet another python/ca`
