JMP Addin Enable/Disable - JSL code to do this?

[#1]

Is there any JSL code/command that can toggle a JMP Addin to Enable/Disable? 
(note: I do not mean Register/Unregister in this case)

This enabling/disabling can be done manually in View > Add-ins with the Enable checkbox, but I need JSL code to control this in my application.  I also looked into loading the "addinRegistry.xml" as a text file and replacing the last string of "autoLoad="false"" with nothing and saving it, but the issue is that JMP overwrites the xml when it closes and will just overwrite any change I make to it.  And I would rather not have to mess with the .xml of course.  I also realize there is a JSL command as "Register Addin()" with its attribute <<LoadsAtStartup(0) ...but this doesn't seem to disable the Addin and it launches the addin again.  (unless I was doing something wrong)  Any other ideas?  thanks, DJ

You can do this -- it is not immediately clear how as it is named different from the GUI, but this is what you'd do if you have an addin of ID "com.mycompany.jmpaddin"

Names Default To Here( 1 );
addin = Get Addin( "com.mycompany.myaddin" );
addin << Unload // to "unregister"
addin << Load // to "register"

I don't see any documentation for this though, got it through trial and error...

And just to state -- unloading an addin does not get rid of any namespaces / classes / global variables set by the addin.  It just get's rid of any menu customizations and prevents it from loading when JMP starts next.

Excellent!  That works great.  Thanks for sharing this!  DJ
