Re: [Jmol-users] script variables treated differently in headless version than in application?

[Robert H. <ha...@st...>]

Jmol is not set up to load arguments into -s headless.spt

While that is an interesting option, it's just not there. I think the thing
to do is use -J instead of -s. This will run an in-line script, which can
then call your headless.spt script with a parameter:

java -jar "%JMOL_HOME%\JmolData.jar" -ion -J "headless.spt('$CC')"

also, I note that when running headless you still need the
*-Djava.awt.headless=true* option, although perhaps on your machine you
have set all Java to be headless.

java -Djava.awt.headless=true -jar "JmolData.jar" -J "prompt 'ok' "
JmolData using command options ["-J", "prompt 'ok'"]
{headlistMaxTimeMs=60000, noConsole=true, exit=true, JmolData=true,
isDataOnly=t
rue}
*Operating headless* display=null nographicsallowed=false

it is better to take what answer we get.
