Functions and values

Function or value	Description
`alert msg` Full Usage: `alert msg` Parameters: msg : `'a`	msg : `'a`
`assertNotNull obj msg` Full Usage: `assertNotNull obj msg` Parameters: obj : `'a` msg : `'b` Returns: `'a`	Assert js object is not null, and return it. obj : `'a` msg : `'b` Returns: `'a`
`debugLevel` Full Usage: `debugLevel` Returns: `int`	Returns: `int`
`delayedDispatch dispatch delayInMs msg` Full Usage: `delayedDispatch dispatch delayInMs msg` Parameters: dispatch : `'a -> unit` delayInMs : `int` msg : `'a` Returns: `int`	dispatch : `'a -> unit` delayInMs : `int` msg : `'a` Returns: `int`
`emptyJsList ()` Full Usage: `emptyJsList ()` Parameters: () : `unit` Returns: `'a`	() : `unit` Returns: `'a`
`fshaprListToJsList list` Full Usage: `fshaprListToJsList list` Parameters: list : `'a list` Returns: `'a0`	list : `'a list` Returns: `'a0`
`getBigintEventValue event` Full Usage: `getBigintEventValue event` Parameters: event : `Event` Returns: `BigInteger`	event : `Event` Returns: `BigInteger`
`getFailIfNull jsObj fields` Full Usage: `getFailIfNull jsObj fields` Parameters: jsObj : `'a` fields : `string list` Returns: `'b`	Access nested fields of a js object, failing if at any point of the chain the requested field is null. Should be used when the fields are guaranteed to exist. For example ["a"; "b"; "c"] is equivalent to the jsCode `obj.a.b.c`, but with checks against null at every layer. jsObj : `'a` fields : `string list` Returns: `'b`
`getFloatEventValue event` Full Usage: `getFloatEventValue event` Parameters: event : `Event` Returns: `float`	event : `Event` Returns: `float`
`getInt64EventValue event` Full Usage: `getInt64EventValue event` Parameters: event : `Event` Returns: `int64`	event : `Event` Returns: `int64`
`getIntEventValue event` Full Usage: `getIntEventValue event` Parameters: event : `Event` Returns: `int`	Get the value for a change event in an input number box, making sure it is an F# integer (JS integer values may not be precise) event : `Event` Returns: `int`
`getProcessPrivateMemory ()` Full Usage: `getProcessPrivateMemory ()` Parameters: () : `unit` Returns: `int`	() : `unit` Returns: `int`
`getTextEventValue event` Full Usage: `getTextEventValue event` Parameters: event : `Event` Returns: `string`	Get the value for a change event in an input textbox. event : `Event` Returns: `string`
`getTextFocusEventValue event` Full Usage: `getTextFocusEventValue event` Parameters: event : `FocusEvent` Returns: `string`	Get the value for a blur event in an input textbox. event : `FocusEvent` Returns: `string`
`globalGC` Full Usage: `globalGC` Returns: `unit -> unit`	Returns: `unit -> unit`
`heapLimit ()` Full Usage: `heapLimit ()` Parameters: () : `unit` Returns: `int`	V8 heap size limit in bytes (set by --max-old-space-size in Main.fs). NB totalJSHeapSize (maxHeap) is the currently allocated heap, not the limit. () : `unit` Returns: `int`
`isNull obj` Full Usage: `isNull obj` Parameters: obj : `obj` Returns: `bool`	obj : `obj` Returns: `bool`
`jsListToFSharpList jsList` Full Usage: `jsListToFSharpList jsList` Parameters: jsList : `'a` Returns: `'b list`	Transforms a js list of jsType into an f# list of jsType. If jsList is not a js list, fail. jsList : `'a` Returns: `'b list`
`jsType var` Full Usage: `jsType var` Parameters: var : `obj`	var : `obj`
`loggingMemory` Full Usage: `loggingMemory` Returns: `bool`	Returns: `bool`
`maxHeap ()` Full Usage: `maxHeap ()` Parameters: () : `unit` Returns: `int`	() : `unit` Returns: `int`
`memSize` Full Usage: `memSize` Returns: `int`	Returns: `int`
`periodicDispatch dispatch delayInMs msg` Full Usage: `periodicDispatch dispatch delayInMs msg` Parameters: dispatch : `'a -> unit` delayInMs : `int` msg : `'a` Returns: `int`	dispatch : `'a -> unit` delayInMs : `int` msg : `'a` Returns: `int`
`productionBuild` Full Usage: `productionBuild` Returns: `bool`	Returns: `bool`
`setDebugLevel ()` Full Usage: `setDebugLevel ()` Parameters: () : `unit`	Hack to provide a constant global variable set from command line arguments of main process. 0 => production. 1 => dev. 2 => debug. Also reads --log=wire,sim, which is the only way to have a log category on before the first line of startup runs - the Development menu and window.issieLog can only be reached later, by which time loading a project is already over. () : `unit`
`startTimer label` Full Usage: `startTimer label` Parameters: label : `string`	label : `string`
`stopAndLogTimer label` Full Usage: `stopAndLogTimer label` Parameters: label : `string`	label : `string`
`usedHeap ()` Full Usage: `usedHeap ()` Parameters: () : `unit` Returns: `int`	() : `unit` Returns: `int`
`uuid ()` Full Usage: `uuid ()` Parameters: () : `unit` Returns: `string`	return a v4 (random) universally unique identifier (UUID) Under plain .NET the npm uuid package is not there, and a Fable import compiles to code that throws when called. Minting an id is not draw-block-specific - every path that adds a component or a port needs one - so the tests could not reach any of them. .NET has its own v4 generator, and nothing depends on which one produced an id, only that it is unique. () : `unit` Returns: `string`
