Jmol users:

The numbers are flying fast because of minor bugs we are finding and the 
desire to get them fixed and onto the Sourceforge site as quickly as we 
can. This announcement covers 10.9.74-10.9.76.


display/hide/displayed/hidden
-----------------------------

Jmol 10.9.76 introduces something I've wished Jmol had for a LONG time 
-- a friendly, reversible "restrict" option. So, here it is. I believe 
this makes "restrict" obsolete. (But don't worry, we won't removed 
"restrict"!)

These commands behave much like "select". Four new keywords are introduced:

display
hide
displayed
hidden

so we have:

display */1 or */3  # display just models 1 and 3

display all  # return to full display

display hidden # show the complement of what is displayed

hide displayed # same thing

hide hidden # nothing new, but it displays how many atoms are hidden

hide hidden or _Fe  # add iron to the hidden set

hide hidden and not _O  # remove oxygen from the hidden set

display molecule=1 # do exactly that

display within(molecule,symop=3)

# This one is a bit tricky -- it first selects for a certain symmetry 
operation (such as -x, y+1/2, z), and then it adds to that any atom in 
the connected set. So you get a full molecule, not just a piece of one.



configuration for cif
---------------------

I've changed the name of "conformation" to "configuration" because I 
think it is a more general term (maybe) -- I'm leaving "conformation" in 
there still -- and with display, it's terrific:

configuration 1  # selects altloc undefined or altloc first listed
display selected
color altloc     # red for constant, green or blue for alternate locations

Note that for PDB or mmCIF models, "configuration" also recalculates the 
secondary structure based on the revised set of group atom positions. 
Then it returns the selected set.


popup menu
----------

Major revisions should make this actually useful -- it is now highly 
dynamic, changing with each model viewed using "frame" or "model", and 
updating to reflect such things as whether it's a PDB file, what it's 
HETATM groups are, lists of configurations, molecular orbitals, options 
for displaying symmetry, correct listing of atoms and bonds.

More to come on this (lists of symmetry operations, for example). Your 
input appreciated.

One possibility is that this popup menu can (also) be a part of the 
console as a fixed menu bar. Good idea? Not?


history and #--
---------------

There are still issues to be resolved here. My goal is to get Jmol to 
the point where you can always see a record of what commands were given, 
no matter how they are given -- from the pop-up menu, from the 
application toolbar, or from atom picking. We have a ways to go on that, 
but I've now identified all the issues and am slowly making my way 
through them. As of 10.9.76 anything you do from the popup menu is added 
to the history. Typing the word "history" at the command prompt now 
delivers the history of all commands given. For those who have scripts 
that you want run but you do NOT want added to the command history, just 
add "#--" to the end of each line of the script you want ignored. That 
line of commands will be run, just not added to the script history.
