class REPLServer

package js.node.repl

extends EventEmitter

@:jsRequire("repl","REPLServer")

Instances of repl.REPLServer are created using the repl.start() method and should not be created directly using the JavaScript new keyword.

Variables

read onlycontext:DynamicAccess<Dynamic>

It is possible to expose a variable to the REPL explicitly by assigning it to the context object associated with each REPLServer.

Methods

clearBufferedCommand():Void

The replServer.clearBufferedCommand() method clears any command that has been buffered but not yet executed.

See also:

defineCommand(keyword:String, cmd:REPLServerOptions):Void

defineCommand(keyword:String, cmd:(rest:String) ‑> Void):Void

The replServer.defineCommand() method is used to add new .-prefixed commands to the REPL instance.

See also:

displayPrompt(?preserveCursor:Bool):Void

The replServer.displayPrompt() method readies the REPL instance for input from the user, printing the configured prompt to a new line in the output and resuming the input to accept new input.

See also:

setupHistory(historyPath:String, callback:(err:Null<Error>, repl:Null<REPLServer>) ‑> Void):Void

Initializes a history log file for the REPL instance.

Inherited Variables

Inherited Methods

Defined by EventEmitter

addListener<T>(eventName:Event<T>, listener:T):TSelf

Alias for emitter.on(eventName, listener).

See also:

emit<T>(eventName:Event<T>, args:Rest<Dynamic>):Bool

Synchronously calls each of the listeners registered for the event named eventName, in the order they were registered, passing the supplied arguments to each.

See also:

eventNames():Array<EitherType<String, Symbol>>

Returns an array listing the events for which the emitter has registered listeners. The values in the array will be strings or Symbols.

See also:

getMaxListeners():Int

Returns the current max listener value for the EventEmitter which is either set by emitter.setMaxListeners(n) or defaults to EventEmitter.defaultMaxListeners.

See also:

listenerCount<T>(eventName:Event<T>):Int

Returns the number of listeners listening to the event named eventName.

See also:

listeners<T>(eventName:Event<T>):Array<T>

Returns a copy of the array of listeners for the event named eventName.

See also:

off<T>(eventName:Event<T>, listener:T):TSelf

Alias for emitter.removeListener().

See also:

on<T>(eventName:Event<T>, listener:T):TSelf

Adds the listener function to the end of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.

See also:

once<T>(eventName:Event<T>, listener:T):TSelf

Adds a one-time listener function for the event named eventName. The next time eventName is triggered, this listener is removed and then invoked.

See also:

prependListener<T>(eventName:Event<T>, listener:T):TSelf

Adds the listener function to the beginning of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.

See also:

prependOnceListener<T>(eventName:Event<T>, listener:T):TSelf

Adds a one-time listener function for the event named eventName to the beginning of the listeners array. The next time eventName is triggered, this listener is removed, and then invoked.

See also:

rawListeners<T>(eventName:Event<T>):Array<T>

Returns a copy of the array of listeners for the event named eventName, including any wrappers (such as those created by .once()).

See also:

removeAllListeners<T>(?eventName:Event<T>):TSelf

Removes all listeners, or those of the specified eventName.

See also:

removeListener<T>(eventName:Event<T>, listener:T):TSelf

Removes the specified listener from the listener array for the event named eventName.

See also:

setMaxListeners(n:Int):Void

By default EventEmitters will print a warning if more than 10 listeners are added for a particular event. This is a useful default that helps finding memory leaks. Obviously, not all events should be limited to just 10 listeners. The emitter.setMaxListeners() method allows the limit to be modified for this specific EventEmitter instance. The value can be set to Infinity (or 0) to indicate an unlimited number of listeners.
