In my launching plugin, I am using an extension
"org.eclipse.dltk.launching.interpreterInstalls" to add our own
interpreter automatically as default interpreter.so when we clear
workspace abd start our IDE it automaticlly picks and add our interpreter
in the interpreter preference page.But it does not select it as default
interpreter.Before running the script ,the user has to go to interpreter
preference page and manually check the interpreter and set it as default
interpreter.
But we dont want user to take care of setting the default interpreter.Is
there any mechanism by which it will automatically picks the interpreter
given through "org.eclipse.dltk.launching.interpreterInstalls" extension
and adds it as default (i.e check the box). So when the user starts our
IDE it will be automatically set and the user should not bother about
setting interpreter.
