Hi All,
Some work has already been done to implement a repeat capture mode for
PulseView which automatically rearms the trigger for repeated captures, with an
adjustable time delay between when each capture segment completes and the next
one starts.

This feature has not been merged yet, so I'm continuing work on it following
the suggestions in the prior email exchange to better fit the UI and
architecture. Changes are on github:
https://github.com/sigrokproject/pulseview/pull/38
This is a work in progress and I would appreciate some guidance in getting it
merged, since I agree that it is a useful feature. Code on this branch can
compile and run, but has a problem switching the segment display mode while a
repeat capture is running.
Open questions
- Session states: The new repeat mode means that a capture session may return
to `Running` state repeatedly. However `pv::views::trace::View` expects the
transition to `Running` state to happen only once per capture and uses it as a
signal to reset the state of the UI which interferes with segment display. More
states can be added to the session but I don't know whether it is best to do
so. See comments in view.cpp.
- Configuration UI: Layout, labels, defaults
- Icons
- Terminology of this feature (both in UI and in code): "Repetitive trigger rearming" is
descriptive but verbose. "Retriggering" is concise but doesn't convey the fact that the
repetitive capture might not be retriggered immediately after the delay time, rather the trigger
condition is *rearmed* and capture may start some time later.
Thanks,
Ivan

I am happy to see someone continue this work.
I always thought it the most glaring non-capability.
I think of this capability as analogous with "Auto" on oscilloscopes. This is
my most common setting when initially exploring a problem.
I did not completely agree with the suggested rationale, but perhaps I did not
fully understand the session concept.
I thought it added excessive complexity, but getting it done is more important.
