movitz

Movitz: a Common Lisp x86 development platform

Implementations

The implementation I recommend building movitz with is SBCL. CCL's repl is broken on s-exprs and CLISP cannot even build movitz correctly as of now.

Getting started with an image

First, fire up your Lisp implementation and load the movitz.asd file. Afterwards, load the system, change into the movitz directory, and evaluate the form (movitz:create-image). When the symbolic image finishes loading you can then dump the image with (movitz:dump-image :path "foo.img"), which will dump the image associated with the variable *movitz:image* to foo.img.

Now there are two options:

• Use the image directly
• Concatenate the grub bootloader with foo.img; for example, cat grub-bootloader/grub-bootloader.img foo.img > hda.img

You can use qemu-system-i386 foo.img to run the image in a virtualized environment.

Movitz and Slime

To enable the Movitz extension to Slime, evaluate

(add-to-list 'load-path "/path/to/movitz/ide/") (load-library "movitz-slime")

You can then use movitz-mode in conjunction with slime. For example, say you have created a symbolic image with (movitz:create-image); then you can work with the Movitz source as with any Lisp source. The commands provided by movitz-mode, such as movitz-compile-defun (M-C-x), movitz-disassemble-defun (C-c C-v), etc. manipulate the symbolic image in movitz:image (typically the image you last created with create-image). In order to actually run any code you compile, you have to re-dump and re-boot (which movitz-dump-image-and-qemu (C-c C-d) is supposed to do automatically. If you just want to dump the image you can use `(C-C d)).

You may need to set the variable movitz-mode-qemu-binary-path in order to have qemu automatically execute the image.

Using the Image Browser

The image browser, written in the CLIM framework, can be used to graphically examine the contents of the symbolic image. In order to use the graphical browser you must first create and dump a symbolic image. Then you can use (movitz-browser:browser) to invoke the image browser.
