VICE: attach disk image and run .prg file from OS filesystem

With VICE (2.4.27 on Linux), I'm trying to figure out how to attach a D64 image to drive 8 (with TDE) while running a .prg file from my OS file system.

I've tried a wide variety of command line options, but I either get a message about extra arguments on the command line, or VICE tries to load the .prg file from the attached disk image, which obviously fails as well.

Does anyone know how to do this? I'm trying to keep my assemble-run-debug cycle as fast as possible.

Not that I'm aware of.

I'm working on one, already got most of the backend working (C library that handles D64, D71, D81, T64, ARK, ZipCode and a few other images/containers). Just need to decide on a GUI toolkit for the frontend, I'm probably stuck with Gtk3 since Qt needs C++, and I really don't like C++.

You could always use c1541 which comes with VICE, but that's of limited use if you want to do BAM manipulation or dir art.

If you mean a tool to create .d64, CC1541 works as well:

Take a look at the goofs!

DirMaster works in Wine.

People actually use that?

Obviously. And why shouldn't they? It creates disk images optimised for demos, while C1541 emulates the KERNAL save behaviour, which is not suited so well for demos. And yes, similar tools exist, and everyone who can rolled their own. But still... (My loader comes with its own incarnation of CC1541, Jackasser and i are still bickering over the details of the merge settlement. Well, not really :D)

That, I understand, fastloaders need a different sector interleave and such. I guess I was a bit surprised by the code itself, such as calling strlen() in a loop and an uncomfortable mix of C and C++.

I'm pedantic, I know ;)

I can recommend the use of snapshot files combined with the remote monitor. As the final steps in your build pipeline, inject the updated code and/or data into the snapshot (very straightforward to do), then send commands to the remote monitor of the running emulator to reload the snapshot and jump to the start of your code:
 echo 'undump "snapshot.vsf"' | nc localhost 6510
 echo 'load_labels "labels.txt"' | nc localhost 6510
 echo 'goto .Start' | nc localhost 6510

I don't think it's possible to detach/reattach a disk image using the monitor though, so if you need to do that you must do it manually in the emulator or make your build system kill and restart the emulator when necessary.

i dont recommend using snapshots for development - as the whole snapshot thing is highly complex and almost impossible to test properly, you'll get unexpected results sooner or later....

and yes, attaching a disk in monitor is possible:

$ attach disk.d64 8

Build by copying then modifying a known working base snapshot image, and you should be fine. Works well for me, at least.

Duh, I must have been looking at the documentation for an old version, didn't notice that. Thanks!
