Defined Macros

Example #1: Calling a basic macro function The currently listing of defined macro functions can be found at Proteopedia:Macros.

Using Macros

Integrating macro use into JSmol code is straightforward. This example doesn't require any parameter to act. It causes the structure shown to 'bobble()'.

<jmol>
  <jmolButton>
    <script>script /mc/ktheis.spt;bobble()</script>
    <text>Start Bobbling</text>
  </jmolButton>
</jmol> <jmol>
  <jmolButton>
    <script>exit</script>
    <text>Stop Bobble</text>
  </jmolButton>
</jmol>

The bobble() button triggers the action. The other button uses exit to stop the looping bobble.</br> You can try the result here:

Example #2: Supply the macro a parameter

This example shows how to specify an item or items to act on by passing in a parameter. It is based on the 'Link' example at Jmol/Interactivity where the ligand 'blinks'.

Example code:

(<jmol>
  <jmolLink>
    <script>script /mc/ktheis.spt;blink({HEM})</script>
    <text>☼</text>
  </jmolLink>
</jmol>)

You can try the result here:
To highlight the heme group, click on the green sun symbol in the parentheses --> ()

Example #3: Another showing supplying the macro a parameter

Example code:

<jmol>
<jmolLink>
    <script>script /mc/ktheis.spt;peekaboo({HEM})</script>
    <text>Hide Heme for a moment</text>
  </jmolLink>
</jmol>

Coding New Macros

Advanced users who want to code additional macros can get a flavor for the JSmol operating behind the scenes and ideas on how they'd code their own by examining the code for macros already available. To view an example go the Proteopedia:Macros page and note that examples such as the 'bobble()' example include notes on how you import it using script /mc/ktheis.spt. In particular note the /mc/ktheis.spt part after 'script'. That is the address of the script code stored at Proteopeida. Place that part after after http://proteopedia.org/wiki/ so you end up at http://proteopedia.org/wiki//mc/ktheis.spt where you can see the code for several defined macro functions.
