I definitely agree with the notion of having a way to escape all
control
characters except for tabs; I already have some logic in place in my
applications to handle literal tabs, but other control characters make
sense to escape. Right now I have to turn off the feature to escape
control characters just to preserve the tab behavior so as not to break
parsing. +1 for this suggestion from me!
Folks, message heard, I'll see if I can add a global option for
escape-all-but-tab. HOWEVER, my question was a different one ;)
I was talking about escapes for script expressions, inside constant
strings. So
If $something contains 'aaa<escape here>bbbb' then ...
This was triggered by Radu's question on how to escape backslash. With
that said: do we need more than \\, \', \xhh inside script constants?
In light of the fact rsyslog supports octet framing which means log
messages may actually contain new lines, it might be less surprising for
end users to be able to specify \r and / or \n directly without having to
specify it by hex code, but the hex code provides enough flexibility to
cover almost any circumstance. I could see you going either way.
good point, I forgot about that.
