Need stderr or equivalent alternative to Info
In some situations informative output gets in the way of desired output (eg, foamDictionary output - EP702).
We can avoid some of this output with argList::noBanner()
. In the .org version they have replace this with a dedicated InfoHeader message stream, which handles the same problem. However, we may also to have a more general solution (cf. #881 (closed)).
In similar cases it could also be helpful to have a Serr that only outputs on the master.
With dynamic code generation (eg #calc
) the process generated copious quantities of output, all of which land on stdout.
Perhaps we need a version of system()
with a dup2()
to redirect.
