Hi David,

Hi there, can you give me any tips for where to get started adding a new function "sendkeys" to the monitor that is essentially like "sendkey" except for multiple keystrokes?

I don't really think that is needed. The sendkey command was implemented to send real keystrokes. A 'sendkeys' can always be simulated using multiple strokes.

I'm using Qemu for some automated testing (in conjunction with AutoIt on the guest XP image) and it's working great. Essentially, I've set up:

1) A stock XP guest image with all windows closed except for a big command prompt that has keyboard focus.

2) A script on the Linux host that launches the guest with "-loadvm" and "-monitor stdio" that uses "sendkey" to start an AutoIt script inside the guest.

The AutoIt script does all the heavy lifting of actually running the automated test. However, I need "sendkey" in order to download the latest test script into the guest OS, and then to run it.

This works fine today, but I'm finding my Linux host scripts full of long strings of:

        sendkey ret
        sendkey a
        sendkey kp_decimal
        sendkey a
        sendkey u
        sendkey 3
        sendkey ret

I'd much rather do something like:

        sendkeys wget\ret
        sendkeys script.au3\ret

You could just create a script/program that converts your command line to several 'sendkey' commands. An idea of how to implement that in C is attached.

I'm guessing this is a very straightforward addition to the monitor code. However, the Qemu source is rather imposing and I'm not sure where to start.

This would be monitor.c. Afaik every handling of the monitor command line is done there. I still don't really think it's necessary.
