Yes, you are right, Bob. There is no problem today ;-(
But I swear it was not working yesterday. Just empty outputs when I
queried for an array element. Goblins, probably.
The issue behind is more complex, as you guessed. I was just trying
to poke and see where the real problem was.
After playing and trial, I found a cure. I'm not sure what is the
rationale behind. Will try to describe it in a simplified example.
This affects a script Eric did in Proteopedia for Molecular
Playground (MPSupportVersion01.spt) so it's important to sort it out
properly. Right now Ppedia uses Jmol 11.8 and the problem doesn't
show up, but when I use it with 12.2 it just chokes.
There is a first script file that is called, loads the model and also
calls a 2nd script file (mentioned above).
// script#1 //
1. calls script#2 using the "script" command
2. loads the pdb file
3. defines the array and passes it to a function which is defined in
script#1
var elist = array("C", "O", "N", "S")
elementColorKey(elist)
// script#2 //
1. defines a (global) variable
colorCarbon = "[xA8A8A8]"
2. defines a function
function elementColorKey(elist)
which contains
if (elist[i] == "C") { colorKey("Carbon", @colorCarbon) }
That's where the error generates and the script stops. The error
complains of an empty color specification ( color "" ) in the "color
echo" line.
When I removed the @ inside the function (just colorCarbon as 2nd
parameter), the problem is gone in 12.2
3.
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
function colorKey(keyText, keyColor)
{
var vertDrop = colorKeyLineHeightPct * (colorKeyIndex - 1)
var vertPct = colorKeyTopVertPct - vertDrop
var echoName = "keyEcho" + colorKeyIndex
set echo @echoName [0 @vertPct %] # upper left
if (backgroundColor == "[x000000]") { background echo black }
else { background echo white }
background echo translucent 6
color echo @keyColor
font echo @echoColorKeyFontSize sansserif bold
echo @keyText
colorKeyIndex = 0 + 1 + colorKeyIndex
#print (0 + colorKeyIndex)
}
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
