Invert boolean variable for layer display

Being able to set the Value of Var z depending equal to !Y in Local Variables would already solve this:
so lets say I have a boolean “Show Edit Dialog” and now I want to link the variable “Forbid change” (applied in another comp) to it, so that whenever Show Edit Dialog is true, Changing some other component is forbidden.

Or do I oversee something and this is already possible?

Thank You!

Thank you!

I also use always 2 variables and when I change the value of variable1 I also update “variable2 = not variable1” and vice versa. The 2 variables are not the problem, but always keeping both in sync is very annoying. In the variables panel you can set “variable1 = variable2”, it would be nice if figma would just allow boolean operators in there, so you can set any combination of other boolean variables (e.g. NOT variable1 AND variable3 OR variable 2) as value of another variable.

Why this feature is desired?

I also encountered this “problem” in Figma. Mainly this feature is required because there are plenty of common situations that would benefit from it. For instance if you create a basic todo-app-ui then a todo is “done” or “not done” for which you likely have two visual appearances that depend on one variable. Sure, there are workarounds, but the workarounds have a lot of downsides, so implementation of the requested feature (show when x is false and hide when x is true) is very much desired.

Why two variables for each boolean don't scale

There is the workaround with having a “active” and “inactive” boolean variable. This however does not scale well because:

• You have to add to variables for one boolean while.. booleans have two states you could benefit from
• You have to change both variables everytime the situation changes
• Your list of variables is twice as long and thus finding the right variable is more difficult
• Your list of variables is twice as long and thus keeping overview over it is mentally harder

Why component-variants don't scale

There is the workaround of creating component-variants for the true and false state. That however isn't maintainable either. If there are more variables at play you get a multitude of component variants. For instance if you have 5 booleans, you'd have 2^5 = 32 variants to possibly maintain.

+1, every time I need to build error messages in a prototype, I need an inverse boolean. e.g. if something is false, show the error layer.

+1, I’m confused that this isn’t a thing already, as it seems so elementary to me.

Well, only 25 votes. 

Will this ever be implemented? It seems like such a tiny addition with a lot of potential.

Well, only 7230 views.

A request like “Invert boolean variable for layer display” getting 7,230 views in 2 years means thousands of people have run into the same issue. You don’t search for and click something that specific unless you’re facing it yourself.

Votes show explicit support, but views show recurring need - and in cases like this, the audience is already self-filtered. Ignoring views risks missing the real scale of the problem just because many readers didn’t (or couldn’t) vote.

I couldn’t agree more, also there are several feature requests asking for this..so votes and views for all of them should be considered
