Actually --trim can act like -F (temperature scale) -- only on the component
you want. It would passed as an argument to owserver and determine the output
format.

Subject: Re: [Owfs-developers] ow* Output - leading spaces trimmed?
Maybe I am an old chap. If I do not like a function in an API, I just create a
wrapper and use my own wrapper in my code. In an object oriented environment it
is even simpler, I can create my own class that extends the original and
changes any behavior I need to behave differently. I am not literate in python,
so unfortunately cannot provide an example, but it should be straight forward.
Even a switch to owfs can cause trouble, as then there will be components that
need owfs be running with --trim, and other components that need owfs without
--trim. To use both kinds of components in a solution, you will need ownet and
two owfs instances just to avoid trimming in the code.

Hi,
I also think, that something like that would be a nice solution. Possibly, you
could even change the default and offer --pretty or --no-trim to restore the
old behaviour.
I think the default should be without spaces, but we should not forget about
legacy applications, of course.

Why is command line argument (--trim) a bad idea?

Hmm, if you get "null", is this different from a bunch of spaces with no
value?
Either fully or not, a switch is another bad workaround..
My other 2 cents..
