What? No Menu?
-
Yes,
UI.menu('Plugins').add_item('Hello') { puts "World" }works.But does
x = UI.menu('Plugins') x.add_item('Hello') { puts "World" }
work for you? -
No, but this does:
x=UI.menu('Plugins');x.add_item("hi") { puts "hi" }
(single line.)

...
This makes no sense...

I think it has something to do with the fact that
UI.menu()returns a new object each time:UI.menu("Plugins") #<Sketchup;;Menu;0x5dbf1c0> UI.menu("Plugins") #<Sketchup;;Menu;0x5dbeff8> UI.menu("Plugins") #<Sketchup;;Menu;0x5dbee30> UI.menu("Plugins") #<Sketchup;;Menu;0x5dbec68> UI.menu("Plugins") #<Sketchup;;Menu;0x5dbeaa0> -
But still.... the exact same code saved as a .rb works.

That's because the code is executed all during one frame, which also explains why the one-liner works.
My guess is that Sketchup creates a new menu , adds the items, and does the validation each frame, instead of just using one menu.
-
frame?
-
I suppose refresh is a better term. I was referring to a frame in animation.

Thread may be a better word.
Examine the eval.c file in the Ruby source and you'll see that files are treated a bit differently.

This is exactly right. It depends on the context available when commands are executed.
Another way to specify multi-line commands in Ruby is to use ''
You could do:x = UI.menu('Plugins') \ x.add_item('Hello') { puts "World" } \ x.add_item('Hello2') { puts "World2" }and it would work and be all executed as a single command.
