Re: [B.A.T.M.A.N.] [patch] adding subgraph-feature to vis-output in dot-file-format

Hi Linus, Simon

One of the things on the TODO list for mainline is to strip out all
the graphvis/JSON formatting done by the kernel and put it into user
space, probably batctl, or another standalone tool, or maybe even a
little library...

Why:

1) No other file in /proc does any special formatting.
2) What happens when one tool wants graphvis and another JSON, at the same time?
3) What happens when you want a third, forth, fifth format etc...

Are either of you interested on working on this?

I guess the first step is to design a file format for vis in proc. I
would suggest space separated values. Maybe one line per
vis_into_entry? I would also suggest the quality value is 0-255, not a
real number. User space, which has float support, can then turn it
into a float if need be.
