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.
br,
Why don't you use the DS2482-800 as busmasters?, then you can make a
hub for a star configuration.
like i did on http://fstab.nl/en/beaglebone, it will work also for the
raspberry

Actually --trim can act like -F (temperature scale) -- only on the component

What do you mean by my clients still have to expect both, wether the user
added --trim
or not ? I'm unclear on your setup.
Do you mean programs or people? If it's a program, you can add --trim in
the initialization string.

Hi,
did anybody already do something asking owhttp (JSON) from within
another Site (same host, another port - which Same-Origin-Policy disallows)?
The Basics are clear, CORS or JSONP, just don't want to re-invent the
wheel ;)

Vajk is right, it's surely easy to change/adopt in any client as we do
it now by ltrimming the values..
I personally just never liked the default space-padding but it will
probably break some things;
A commandline option helps out personally but won't change anything here

Thats exactly the overhead I want to avoid like
owserver-owget/ownet-sql-CGI-Client
Doing this with - let's say 50 sensors - every 10sec produces a bunch of
useless load where the client only needs it once a week for 2h..

i don't see a big overhead in this scenario, maybe with 100 users, but
with more than 1000+ users, i prefer a sql server, not a sqlite database,
with cache, etc etc...

If you really need a tree, you have to put a DS2409 bus coupler on each

More is surely possible, using
After some hours of investigation, I think implementing JSONP (again,
note the P!) in owhttpd looks like the best solution(?)
This would IMHO also be useful for some other solutions maybe to avoid
useless workarounds like writing DB's and then query the same..
I'm willing to try do it (though

Databases are NOT useless! Besides all the data enforcement, I want to plot
things and store logs and variables. This is a silly thing to say.
If you are firmly against storing any data, for any reason, take the
following boilerplate ajax call (in your web page):
function showMeData(data) {
In order for jsonp to work, you'd have to get httpd on a port that would
make it through whatever gateway devices you plan on routing it through.
You could probably do this on 88, although jsonp must have provision for
this, which I don't know for sure.
