Which stack hosts the externals in runtime?

[Tiemo Hollmann TB]

Hello,

with: put the externalPackages of stack "home" you can check in the IDE,
which externals are loaded.

 

I thought in runtime the externals would be loaded into the mainstack, so
that you could ask for: put the externalPackages of stack "<myMainStack>"

But in my case this shows me just 1 out of 4 externals. How can I check, if
and which externals are loaded in runtime?

 

Thanks

Tiemo
