All On/All Off Tags

Just noticed that my script is not working correctly with tag folders

22

Yes there are other issues as well.

Why do you think you cannot have nested tag folders ? There is nothing in the help that says you cannot. And the Ruby API supports nested tag folders.

Just be aware that tag folders are not themselves tag/layer collections. They are a display feature.
(Meaning that all tag/layers remain children of the toplevel model layers collection.)

Changing this…

if ( layers_toggle.any? {|l| l.visible? == false } )
   	layers_toggle.each {|l| l.visible = true }
	else
	layers_toggle.each {|l| l.visible = false } 
	end

to this works…

if ( layers_toggle.any? {|l| l.visible? == false } )
    layers_toggle.each {|l| l.visible = true }
    layers.folders.each {|l| l.visible = true }
    else
    layers_toggle.each {|l| l.visible = false }
    layers.folders.each {|l| l.visible = false }
    end

But the notes for the folders method says:

Note: This does not return all the folders in the model, only those that are direct children of the layer manager.

So it won’t work on folders that are children of folders… oh well

You may have missed what I said above. Tags(layers) remain children of the top level model layers collection. They are only displayed beneath the folder that their folder property points at.

Notes on your code:

(1) You must not define methods in the top level ObjectSpace. Doing so makes them global and part of class Object. Since everything in Ruby is an object and is a subclass of class Object, your object definitions will percolate into every other coder’s modules and classes as well as the API’s modules and classes … and Ruby’s modules and classes.
So your code must be within a unique namespace module, and then separated into categorical submodules (usually one for each extension.)

(2) The word “toggle” means to change state of a boolean or dual state object. Adding “OnOff” is like a double descriptor. (Also the Ruby convention is for method names to be all lowercase with words separated with underscores. Mixed case method names often come from JavaScript, VisualBasic and C programmers.)

(3) Only use parenthesis around conditional expressions when it is necessary to control the order of evaluation. (if and unless statements in Ruby do not need parenthesis around the conditions like is required in JavaScript or other coding languages.)

(4) A toggle command is not a tool and does not belong on the “Tools” menu.
Either in your own submenu of “Extensions” or perhaps the “View” menu.

Each LayerFolder object has itself a #folders method that returns an array of it’s child folders, and a #folder property that points at it’s parent folder (or nil if it has no parent folder and is a toplevel folder.)

So it’s a tree structure and needs to be walked (which is usually done with a recursive method.)

26

Dan, how right you are. You can have multi-level nesting. So I take back what I wrote in post 9. Having a single top level folder for all tags apart from Untagged would do the trick very simply. I guess this would be better than struggling with code that doesn’t quite cover it all.

Oh, but then you’ll need a code command to set all your layers to be a child of a folder you pick ?
