This example will create a new document in the Ink application and it will write some text there.

Run StepTalk Shell using AppKit environment

> stshell -environment AppKit



Check the application, if it is there...

StepTalk > Ink


Create a new document...

StepTalk > Ink newDocument:nil


... write a text ...

StepTalk > ((Ink currentDocument) -> 'tv') insertText:'Hi there!'


... and now switch to the Ink application and look into the main window what have you done!

Notes

Using -environment AppKit will load AppKit classes and objects and enables the Application finder. Application Finder is an object that will try to find, launch if needed and connect installed application referenced by its name.

If you use object name 'Ink' for the first time, StepTalk will try to find the object using object finders. Application Finder will find it, because there is an application named Ink.app. Application will be launched automatically if it is not running already.
