Scripting API Reference

API reference for developing scripts in Skylight Application Builder.
Parameters in this page denoted with an asterisk (*) are required.
Common Terms
Promise
Many functions run asynchronously, such as the creation of a session. These asynchronous functions return a promise, which means that the function can be awaited (see here for more details) in order to pause execution of the code until that function has completed its operation.
Configuration Object 
Instead of passing in multiple arguments into a function, a dictionary with the parameters as keys and the arguments as values is used instead for functions with two or more parameters. This dictionary is called the configuration object. This paradigm allows us to create code that is both resilient in changes to method signatures as well as provide and/or remove optional arguments more easily.
Global
The other objects (e.g. Session, Application) on this page are accessed through the skylight object (i.e. skylight.session.create()). The global object exists at the root level as its own object.
The global object can be written to and read from all scripts. This enables the ability for scripts to share functions and objects.
One typical use case for this is to define shared constants and functions in the Application Open script, which will then be accessible by all other scripts.
Session
session.create()
(method) skylight.session.create({ name: string, description: string, properties: object, participants: [Participant] }: NewSession): Promise<any>

visible: Whether or not this icon should be shown
label
string
Optional label for the text field
suffix
string
Optional short text field that should be used to denote the units of measure for the data entered, or something similar, eg "lbs"
helpText
string
Optional field for helper message that is displayed below the field
input
string
Existing input, if applicable
header
string
Optional field that provides additional context to the input. Placed above the input box where a view's title is normally displayed.
placeholder
string
Optional text that will be displayed in the field before text is entered
maxChar
number
Optional limit for the maximum allowed characters to be input
characterConfig
object
Optional configuration object for the text input field:
string characters: A string that defines which characters can be input into the text input field. These characters will be displayed on the Skylight character picker on smart glasses.
boolean backspace: Shows the backspace button on the Skylight character picker on smart glasses
boolean cancel: Shows the cancel button on the Skylight character picker on smart glasses
boolean confirm: Shows the confirm button on the Skylight character picker on smart glasses
preferSpeech
boolean
Optional flag to indicate that speech-to-text is the preferred method of input if supported on a wearable device. On Glass EE2 and RealWear HMT-1 the speech-to-text activity will be presented in place of the Skylight character picker.
onSubmit
function
An optional function that accepts an object (herein referred to as lastInput), used to react to a user submitting input
NOTE: await-able onSubmit instances are not supported. You will be able to perform any other skylight API call, but you cannot await a result.
NOTE: preferSpeech will completely bypass this callback.
onSubmit will only be triggered when the user submits their inputted data, not each time they change the input value
onSubmit should accept/expect lastInput to be of the following schema:
lastInput = { get value (){}, // this returns a String setError: (errorText) => {}, // will set error text and state once set. Text is REQUIRED. 
}
​
If lastInput.setError is called with an error string, an error message will be shown within the text input activity. Note that if this is specified, onSubmit should not return a value (or it should return a null/undefined value) so that the text input activity remains.
If onSubmit returns a String value, it will resolve the await call with the returned value which will close the text input activity 
(see example)
It is possible to change the value returned; however, unless used for sanitization or normalization purposes, we do not recommend manipulating the user’s input for the best user experience.
If onSubmit returns a null/undefined value, no data will be committed and the text input activity will remain.

​
A function that accepts a String, used to react to a user submitting input. It should return a String? value.
NOTE: await-able onScan instances are not supported. You will be able to perform any other skylight API call, but you cannot await a result.
If onScan is defined and returns a defined string value, it will resolve the await call with the returned value (see example) and close the scanner as in a successful scan
​
It is possible to change the value returned; however, unless used for sanitization or normalization purposes, we do not recommend manipulating the user’s input for the best user experience.
If onScan is defined and returns a null/undefined value, the scanner experience will not be dismissed and the await will not be resolved
If onScan is not defined, the timeout will be the governing factor in when/how the scanning experience is dismissed and all scans will be considered successful
