Pass Boolean through FS dialog

CAD_SSP · January 2018

At present you cannot pass a boolean through a feature script dialog, this is ideal if you want to hide a feature in certain configurations (rather than forcing them to fail which seems an odd workaround to me).

Something like:

<span style="background-color: transparent; color: inherit; font-size: inherit; white-space: pre-wrap;">annotation { "Name" : "My Boolean Variable" }
</span><span style="background-color: transparent; color: inherit; font-size: inherit; white-space: pre-wrap;">definition.myBooleanVariable is booleanVariable;</span>

A current workaround is to pass the variable name in as a string (without "#") and then check if it is a boolean and so on but is not very intuitive as you want to include the "#" but that stops it working.

I'm not sure I understand this request. FeatureScripts can defintely use boolean inputs. They look like checkboxes.

annotation { "Name" : "My Boolean" }
        definition.myBoolean is boolean;

@mahir what I am trying to achieve is this:
If your partstudio contains a variable that is a boolean such as "#Showitem = false" you cannot pass this boolean value into featurescript (as far as I can see).
A boolean input as you state is a checkbox, you cannot assign a variable value or a formula to it.

The only workaround I have found is to us a string query and pass the boolean name in as text, then you can use the use "getVariable" within FS to check the value i.e.

<div>annotation { "Name" : "Hide If:" }
definition.hideIf is string;</div>

pass in "Showitem" without the "#" and then do a check to see what if anything was passed in:

<div>var hideIfcheck is boolean = false;
<span>if (definition.hideIf != "")
</span>{
    try&nbsp;
    {
        if (getVariable(context, definition.hideIf))
            {
                 hideIfcheck = true;
            }
    }
    catch (error)
    {
        reportFeatureWarning(context, id, "you have used a non Boolean or non-existant variable");
    }
}</div>

This is a messy workaround as you instinctively want to put the variable name when you type it with the "#" but I cannot find a way of removing that within featurescript.

Have you tried isAnything? That will take a variable as input.

isAnything(definition.myBoolean)

A code snippet for Neil's suggestion:

annotation { "Feature Type Name" : "Take Boolean" }
export const takeBoolean = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {
        annotation { "Name" : "Boolean" }
        isAnything(definition.bool);
        
    }
    {
            if (!(definition.bool is boolean))
                throw regenError("Boolean should be a boolean", ["bool"]);
    });

But you may want to consider just using a normal checkbox for your feature and then using configurations to toggle it rather than variables:

That's what I was thinking. Here's an example of configuring the Unsupressed property of a feature, which seems to be exactly what you'd like to do. In this case I used a list input to control suppression state of the circle and square, but I used checkbox inputs to independently control the suppression state of the triangle and pentagon.

Thanks, isAnything is exactly what I want.

Configurations are perfect for most applications but don't suit this particular case.
