Is there any plans to migrate to GTK4?

I would like to add meson build file as it is the preferred method of building vala at the moment. note that I have renamed the file DirectoryClient.vala to directroyClient.vala

project('netradio', 'vala', 'c')

dependencies = [
    dependency('glib-2.0'),
    dependency('gobject-2.0'),
    dependency('gtk+-3.0'),
    dependency('json-glib-1.0'),
    dependency('libsoup-2.4'),
    dependency('gstreamer-player-1.0'),
    dependency('gio-2.0'),
]

sources = files('netRadio.vala',
                'mainWindow.vala',
                'fontAwesomeButton.vala',
                'stationModel.vala',
                'genreModel.vala',
                'streamModel.vala',
                'imageModel.vala',
                'directoryClient.vala',
                'playerController.vala',
                'dbusInterface.vala',
                'dbusServer.vala')

executable('netradio', sources, dependencies: dependencies)

I think:

?? Null coalescing operator, resulting in the left-hand side, if unequal
null, else resolving to the right-hand side.

would be easier to comprehend if written as:

Null coalescing operator: ?? returns the left hand side unless it is Null in which case the right hand side is returned.

Figure 1-1. Build-Time vs. Run-Time Efficiency gives the impression that Perl is slower than Python in both dimensions. This is not the case in my experience. Might it be possible to replace this bubble with a generic term such as "scripting languages" and thereby avoid the contentious issue of which scripting language is the most expressive/fastest etc.?

You could consider xlib being the native UI toolkit for systems running an
X-Window display server; however xlib is such a low-level library that the
categorization “toolkit” would be very euphemistic.

Possible optimistic rather than euphemistic?

To break these, Vala knows the modifier weak.

perhaps cl;earer as:

To prevent these, use the weak modifier.

So, will there be a more recent edition than the one launched in 2019 by Apress?

I read a sample of the book, and I really found it promising. I was even thinking of buying a printed copy.

Would you recommend that I wait until the next edition is released?
