Dear Bob,
My main use for sync is to keep 2-4 molecules, in separate Jmols,
aligned when one is rotated or zoomed with the mouse. I want any
moused Jmol to send, so I command one Jmol "sync * on".
In developing/debugging my Jmol Tutorial-Authoring Template (JTAT)'s
support for 2-4 Jmols, I am running into erratic behavior when sync
is on, and I then send a script to all Jmols. Moveto commands are
particularly problematic, as you can imagine -- I think that during
the execution of a jmolScript("...", "all"), the Jmol is sending
moveto's to other Jmol's -- but concurrently, all are sending since
all received the same jmolScript().
If there is no simple existing solution to this problem, I would like
to suggest a new setting, if feasible, such as
set syncNoScripts
or (meaning the same)
set syncMouseOnly
When on, this would disable sync sending during script execution (as
distinct from moused movements), and automatically restore it at
script termination. It would also make Jmol's sync more like Chime's
synch (which has proven extremely satisfactory).
I have considered trying to turn sync off myself at the beginning of
a script, and then turn it on at the end. The main problem I envision
is the asynchrony of the Jmols. If one finishes early, and I then try
to restore sync-ing with "sync * on", the others may not yet have finished.
Here is another idea. I could rework my code to send "sync . on" to
each Jmol, rather than "sync * on" to one of them. Then I could "sync
. off" at the beginning of a script, and "sync . on" at the end.
As you can see, the Chime-type of synch function would greatly
simplify the code I need in my tutorials. (Chime never synch'd
commands sent via the script mechanism, only mouse movements). What
do you think about a "syncMouseOnly" option for Jmol?
