EPICS to Python / EPICS to Tcl

[Timothy Madden <tmadden@aps.anl.gov>]

Folks

I want to make an IOC that does the following:

Serve PV's that call Asyn, They could BI, BO or any standard record.
Make an Asyn driver that is linked with  a Python or Tcl interpreter. 
The IOC written in C, would then call scripts which could be stored as 
text files on the disk.

A record named "X" would call a script function named "X" and pass its 
PV value to it. Likewise, the output of the script could be passed back 
to the PV value. Python and Tcl interpreters provide ways for C to call 
scripts, pass and retrieve data from scripts. Also, it is not too hard 
to link  an interpreter into a C program. All that is needed is to write 
the ASYN-based C functions that call the interpreter. It could be done 
in Linux or Cygwin.

In this way, one could make an IOC to do whatever one wanted without 
ever messing a C compiler. The user would write a few scripts, make a 
st.cmd file, and a db file. In this way, new IOCs could be very quickly 
developed.

Has anyone already done this?
