How to: IOC reading information from file?

["Marco A. Barra Montevechi Filho via Tech-talk" <tech-talk at aps.anl.gov>]

Hello all.

I want to create a set of configuration files (probably json, yaml or even txt) that i can make my IOC read and put the values into PVs. I could swear i read something about reading configuration files in EPICS documentation before but i cant for the life of me find it again.

Desired functionality would be something like:

file config0.yaml has: {"my_var" : 0}
file config1.yaml has: {"my_var" : 1}

And then i would have a record, say MYRECORD:Output that when i do:

caput MYRECORD:Output "config0.yaml"

the record would output 0 to its output link. And

caput MYRECORD:Output "config1.yaml"

the record would output 1 to its output link.

Is there any module or record that offers similar functionality?

Thanks in advance,

Marco
