Your points are valid and I cannot really say anything against them. The
problem with moving all global functions into the Window object is that this
adds a lot of syntactic baggage that isn't needed in 90% of the cases. We
really prefer the simplicity of
start("Notepad")
write("Hello World!")
press(CTRL + 's')
write("test.txt", into="File name")
click("Save")
press(ALT + F4)
over
notepad = start("Notepad")
notepad.write("Hello World!")
notepad.press(CTRL + 's')
notepad.write("test.txt", into="File name")
notepad.click("Save")
notepad.press(ALT + F4).
Also, there's a problem here: The "Save" dialogue that opens in the above
script is technically a different window so in theory you would have to
introduce a new object to distinguish between the original window that lets you
edit your text document from the "Save" window. This is very tedious and
error-prone. You are right, though, that we have to do some logic in the
background to remember the last window.
In light of this, could you live with something along the lines of design #4?
notepad_1 = start("Notepad")
notepad_2 = start("Notepad")
notepad_1.focus()
write("Hello World!")
press(CTRL + 'a', CTRL + 'c')
notepad_2.focus()
press(CTRL + 'v')
Thanks,
Michael
