Re: IOC implementation by JAVA/Python

[Tong Zhang <warriorlance@gmail.com>]

Hi Jamie and Michael,

Thanks for your message, however what I want is how can I generate some 
PVs in some productive JAVA/Python program/scripts for communicating, 
not the python CA interface nor separately run an IOC; just like 
openXAL, to my understanding, one of the apps of this JAVA based 
framework --- 'virtuallinac' once be launched, an IOC would be running 
background, not by conventional way based on EPICS base routines.
I think Michael's pythonIoc is something what I'm looking for, thanks.

Tong

(https://github.com/Araneidae/epicsdbbuilder) allows you to create EPICS 
database files in Python.  However, the result is a .db file which still 
needs to be executed by an IOC as a separate step.

is a Python interpreter linked with an EPICS IOC and integrated with 
epicsdbbuilder and some Python device support.  This allows you to write 
fairly concise scripts which generate PVs in a simple way.
