- Global JS variable: squared
- ES2018
Library files are in the "/dist" folder. A minimum of two files are required to run squared.
- squared
- squared-base - required: except vdom-lite
- squared-svg - optional
- framework (e.g. android | chrome | vdom | vdom-lite)
- extensions - optional
Usable combinations: 1-2-4 + 1-2-4-5 + 1-2-3-4-5 + 1-vdom-lite
File bundles for common combinations are available in the "/dist/bundles" folder and do not require a call to "setFramework".
The primary function "parseDocument" can be called on multiple elements and multiple times per session. The application will continuously and progressively build the layout files into a single entity with combined shared resources. Using "parseDocumentSync" is not recommended when your page has either images or fonts.

</script>NOTE: Calling "save" or "copy" methods before the images have completely loaded can sometimes cause them to be excluded from the generated layout. In these cases you should use the "parseDocument" promise method "then" to set a callback for your commands.
You have the same features as VDOM framework but you can also bundle assets using HTML syntax and the provided Express server. It is adequate for most applications and gives you the ability to see your application first and to build it last.

});Layout rendering can be customized using extensions as the program was built to be nearly completely modular. Some of the common layouts already have built-in extensions which you can load or unload based on your preference.
// Create an extension

attributeName: [];
};

}
}
}
// Install an extension
const sample = new Sample("widget.example.com", 0, {/* Same as configure */});
squared.add(sample);
// OR
squared.add([sample, {/* config */}]);
// Configure an extension
squared.attr("widget.example.com", "attributeName", ["width", "height"]); // typeof is enforced and will only set existing attributes
// Add project data
const ext = squared.get("widget.example.com");
ext.project.set(element, await fetch(url), "sqd1" /* projectId */); // Same as Map interface with optional "projectId" argumentSome extensions have a few settings which can be configured. The default settings usually achieve the best overall rendering accuracy without noticeably affecting performance.

These two additional output parameters are required when using the "data-viewmodel" prefix.

<!-- res/layout/filename2.xml -->The attributes "data-android-include-start" and "data-android-include-end" can only be applied to elements which share the same parent container. See /demos/gradient.html for usage instructions.
NOTE: "data-pathname-android" AND "data-filename-android" can also be used with any "parseDocument" base element.
Sometimes it is necessary to append elements into other containers when trying to design a UI which will look identical on the Android device. Redirection will fail if the target "location" is not a block/container element.
<div>
<span>Item 1</span>
<span data-android-target="location">Item 2</span>
<span data-android-target="location" data-android-target-index="1">Item 3</span>
<div>
<ul id="location">
<li>Item 4</li>
<li>Item 5</li>
<!-- span -->
</ul><LinearLayout>
<TextView>Item 1</TextView>
</LinearLayout>
<LinearLayout>
<TextView>Item 4</TextView>
<TextView>Item 3</TextView>
<TextView>Item 5</TextView>
<TextView>Item 2</TextView>
</LinearLayout>Using "target" into a ConstraintLayout or RelativeLayout container will not include automatic positioning.
System or extension generated attributes can be overridden preceding finalization. They will only be visible on the declared framework.

node.android("layout_width", "match_parent");
node.android("layout_height", "match_parent");
node.app("layout_scrollFlags", "scroll|exitUntilCollapsed");Only the XML based layout and resource files can be viewed on the Android device/emulator without any Java/Kotlin backend code. To play animations in the emulator you also have to "start" the animation in MainActivity.java.
import android.graphics.drawable.Animatable;
android.widget.ImageView imageView1 = findViewById(R.id.imageview_1);
if (imageView1 != null) {
Animatable animatable = (Animatable) imageView1.getDrawable();
animatable.start(); // Required
}Most mobile applications do not have a deeply nested hierarchy and are generally better to implement using declarative programming.

</div>You can also use "android.substitute" to create fragments within a layout similar to Compose.
Usually you do not render child elements when using Compose View. There are some cases where it can be used effectively to reproduce the desired layout.
