Macro API Objects

You can create macros using the Macro API. By default for use in macros, there are four primary objects available:

  • Session - the main entry point for access to the host. You use the Session object to connect, disconnect and provide access to the PresentationSpace object.

  • PresentationSpace - represents the screen and provides many common capabilities such as getting and setting the cursor location, sending data to the host and reading from the screen. It is obtained by calling session.getPresentationSpace().

  • Wait - provides a simple way to wait for various host states to occur before continuing to send more data or read from the screen. For example, you can wait for the cursor to be located at a certain position, text to be present in a position on the screen or simply wait for a fixed amount of time. All ‘Wait' function calls require the yield keyword, which is explained below.

  • User Interface - automatically available in your macro as the “ui” variable. It provides basic user interface capabilities. You can use this object to display data to the user or prompt them for information. All ‘UI' function calls require the yield keyword.

All available objects

See the list of available objects in the right navigation, "On this page." (You may need to expand your browser.)

AttributeSet

The AttributeSet object allows the user to decode the attributes that are present on the data cell. The AttributeSet object returns values defined in the Attribute object and when used together, you can get formatting information from the data cell.

Method Description
contains(attribute) Determines if the set contains the specified Attribute.
Parameters
{Number} attribute to check
Returns
{Boolean} True if the attribute is in the set
isEmpty() Determines if the attribute set is empty.
Returns
{Boolean}True if the set is empty.
size() Indicates the number of attributes in a set.
Returns
{Number} The attribute count.
toArray() Converts the internal attribute set to an array.
Returns
{Number[]}Array of values of attributes in the set.
toString() Converts the internal attribute set to a string.
Returns
{String} Space-delimited names of attributes in the set.
forEach(callback, thisArg) Function to iterate over each element in the attribute set.
Parameters
{forEachCallback} Callback to perform the specific operation. Called with the name of each attribute in the set.
{Object} thisArg optional pointer to a context object.
forEachCallback(string, object) A user provided callback function where you provide the behavior, to be used as the callback parameter to forEach.
Parameters
{String} String name of an attribute in the attribute set.
{Object} thisArg optional pointer to a context object.

sendUserName() Applies the user name contained in the pass ticket to the field at the current cursor location on the current host screen. The user name must be sent before the password. Sending the password first will invalidate the pass ticket, and you will need to get another one.
Parameters
{String} passTicketKey opbtained from getPassTicket
Returns
{Promise} fulfilled if the user name is successfully sent. Rejected if the operation fails.
sendPassword() Applies the password contained in the pass ticket to the field at the current cursor location on the current host screen. The user name must be sent before the password. Sending the password first will invalidate the pass ticket, and you will need to get another one.

FileTransfer

Use the FileTransfer object to list and transfer files between the host system and the client.

The Host Access for the Cloud file transfer API abstracts the file path conventions used by different host file implementations. Follow URL or Linux file system path formats when formatting file paths used by the API. For example, /root/directory/file.

It is important to observe any rules specific to host systems, such as allowable characters or name lengths.

User Interface

The user interface object provides functions for interacting with the user, prompting for and displaying basic information. The UI object is made automatically available in your macro as the “ui” variable”.

note

Important: All UI functions require the ‘yield’ keyword in front of them. This allows the macro to block execution until the conditions of the UI function have been met.
[parameter] denotes an optional parameter.

Method Description
prompt(message,[defaultAnswer], [mask]) Prompts the user for information in the user interface.
Parameters
{String} message title to display to the user. Default: blank String.
{String} defaultAnswer to use if user leaves it blank. Default: blank String
{Boolean} mask indicates whether to hide the prompt (as with a password)
Returns
{Promise} Fulfilled when the user closes the dialog window. Returns the users input on “OK” or null on “Cancel”.
message([message]) Display a message in the user interface.
Parameters
{String} message to display to the user. Default: blank String.
Returns
{Promise} Fulfilled when the user closes the message window.

Wait

Use the wait object to wait for a particular session or screen state. For example, you can wait until the cursor is found at a particular location or text is present at a certain location before continuing with the macro execution.

Wait functions are often used in conjunction with asynchronous functions such as connect() and sendKeys().

note

All functions take timeouts as an optional parameter and have a default time out value of 10 seconds (10000ms).
Important: All wait functions require the ‘yield’ keyword in front of them. This allows the macro to block execution until the conditions of the wait function are met.
[parameter] denotes an optional parameter.

Method Description
setDefaultTimeout(timeout) Sets the default timeout value for all functions.
Parameters
{Number} default timeout to use for all wait functions in milliseconds.

Returns
{Promise} Fulfilled if the session is already disconnected or when it finally disconnects. Rejected if the wait times out.
forFixedTime([timeout]) Waits unconditionally for fixed time. Time is in milliseconds (ms).
Parameters
{Number} timeout in milliseconds.
Returns
{Promise} Fulfilled after time elapses.
forScreenChange([timeout]) Waits for the host screen to change. This function returns when a screen update is detected. It makes no guarantees about the number of subsequent updates that may arrive before the screen is complete. Waiting repeatedly until the screen contents match some known stopping criteria is advisable.)
