NOTE: This work is partly based on earlier works of J. Mansour and has been supported by A. Rumpf, E. Bassi and other _Nim_ and _GTK/Gnome_ developers.
The `combinatorics` module was kindly provided by R. Behrends.
NOTE: We are currently preparing v0.8.3. You may install it with command [black yellow-background]#nimble install gintro@#head#.
This version will have some internal cleanup, which removes the temporary
Array types. In the past we used that names to indicate array parameters, it was working well, but still
it was ugly using names to indicates data types. So we fixed that. And we have added some better support for
GList parameter. GLists are now converted to Nim seqs and vice versa. Not everywhere still, and this conversion
is still untested, as GList parameters are used most of the time in exotic functions only. Another change is that
we have support for libnice by a request of a user from Japan. We added the sdp_example.nim converted from
a C example, it seems to compile and run. And finally with v0.8.3 the examples from the GTK4 book should work.
For the GTK3 examples we had to do some minimal fixes, so you may have to do similar fixes for your own code as well.
For gintro/examples/gtk3 this was

NOTE: This is version 0.8.2 of gintro. It is only a fix for recent gstreamer 1.18 which added some uncommon
gobject-introspection stuff which brook the install of 0.8.1 for a few users. We where not yet able to
verify that the gst example which is bases on the gst C tutorial1 works with gstreamer 1.18.
