Re: [Jmol-developers] Catch error in jmol

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

You can catch it with the message callback system. Something like this:

function myfunc(app,message){
 var s = message + ""  // BE SURE TO DO THIS!
 if (s.indexOf("ERROR")>=0 && s.indexOf("load >>") >= 0) {
   jmolScript("zap")
 }
}

jmolSetCallback("messageCallback", "myfunc")



the message is in the second parameter and looks something like this:

script ERROR: Unexpected end of file after line 3:
x
for file 
file:/C:/jmol-dev/workspace/Jmol-documentation/script_documentation/examples-11/t.xyz 

type xyz
----line 1 command 1 of file null: load >> "t.xyz" <

You can't prevent it from showing, though, only act on it.
