*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
|
|
`advanced-qml-auto-realod`. It doesn't depend on Swank, and should therefore
|
|
also be stable (it uses a local trivial web server).*
|
|
|
|
*You may even run both desktop and (one or more) mobile device auto reloads
|
|
simultaneously (`swank-server` example only), because they all watch/load the
|
|
same QML sources, if they point to the same desktop IP*

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).

|
|
*So, this is certainly a nice feature of Qt Creator, but personally I prefer
|
|
the simple `lqml run.lisp -auto` variant, which doesn't need compilation, and
|
|
-- more importantly -- can run Lisp code after a QML reload.*
