Hi Bruce and Andrew,

 My intention isn't in EPICS IOC DB, I would like to use msi to handle

many configuration files instead of m4 in specifically ESS EPICS

building environment and my own EPICS building environment as well. I

would like to stay within existent epics applications as much as possible.

 I didn't look at its source codes, but it's better to have a flag to

turn ".undefined" or ",recursive" warning texts.

 However, you can simply ignore my question if you don't have any

resources. Maybe I can spend some time later to implement this feature

by myself.

  Thanks for everything!

I'd be in favor of removing them unless the -V flag was set.

Most of our msi use is intended to be loaded w/ macro definitions in our

st.cmd

file, so it's just annoying to see ",undefined" in files we've built up

from templates

when we know we'll define those macros later.

We set the -V flag only for those few msi uses where the files need to have
all macros expanded.   For those cases it would still be helpful to see

the ",undefined" or ",recursive" warning text in the msi output file as

we do now.

Cheers,

If there is a consensus that they are not useful I have a modification
that removes the ",undefined" error indicator from the output generated
by macLib (and hence the output from msi as long as the -V flag is used)
when it encounters a $(macro) that it doesn't have a value for. There is
also a ",recursive" marker for macros that are defined in a substitution
file using themselves.

As Bruce said, these markers don't change how a file is interpreted by
an IOC when they are present, but if you feed the output into some other
tool that doesn't understand them they might be annoying.

Please discuss here if you particularly like or dislike these markers.

Hi,

   Is there any other way to suppress or omit (,undefined) in the output
file by using MSI?
