Does anyone know if it's possible to pass PV values as arguments to a
program called from an EDM ShellCommand widget?
I can pass EDM macro substitutions easily, simply by passing them as args in
the Shell Command property, e.g.
myShellCommand $(device)
but I cannot seem to pass PV values this way, e.g.
myShellCommand ioc1:myPv
or
myShellCommand $(ioc1:myPv)
doesn't work. Am I missing any obvious syntax, or alternatively does anyone
know if it might be possible to modify EDM relatively easily to support
this?
I could of course just call the shell command with the PV name, and then do
a ca_get from there to get the value, but this seems untidy.
Many thanks
