Please note: the below may be convenient for sketching -- but during development, the simple -auto option of lqml run.lisp may be more appropriate, because it allows for re-initialization (calling Lisp code) after reloading QML.

The above method also works on mobile, please see example swank-server. It doesn't depend on Swank, and should therefore also be stable (it uses a local trivial web server).

You may even run both the desktop and mobile device auto reload simultaneously (swank-server example only), because they both watch/load the same QML sources.

QML Preview and Slime

(LQML >= 22.2.2, see lqml -v)

This shows how to use QML Preview (live QML updates while you are typing).

• edit lisp/main.lisp of an example, and append this line:

(load "~/slime/lqml-start-swank.lisp")

• open app.pro in Qt Creator; under 'Projects' (menu on the left) / 'Configure Project' choose 'Debug' and change the 'Build directory' to build/ from the example

• in the 'Edit' view of Qt Creator make sure that 'Debug' is selected (menu on the left, near the bottom); from the menu at the top choose 'Build / QML Preview' (after a 'Build / Clean')

Now the example should compile and start. You may now select any QML file from the tree view on the left, and any change to QML will be shown immediately in the running app.

Additionally you may also run M-x slime-connect from Emacs (the Swank server should already be running, see 'Application Output' at the bottom of Qt Creator).
