If you mean logic digarams as in "i have nodes that emit logical ONEs
and ZEROs, i have nodes that represent logic gates like AND OR XOR NOT
e.t.c and i have nodes that output the results", then yes. of course
you can write logic diagrams with it. Of course you have to implement
your own Nodes for this, but this is no problem at all since you can
inherit from GtkFlow.Node as baseclass and implement your logic on top
of it. See the example calculator.py in the examples folder.

Using cmake has a simple reason: I spend two days trying to use
autotools in one of my vala projects and gave up frustratedly with no
mentionable result. Then i tried cmake and got a vala project up and
running in one night. I am very happy with it and continued to use it
for other projects.
Currently I see no necessity to switch, but if you want to do it and
maintain it, please do and send a pull request.
To be honest, i am a bit curious what i did wrong and to see a correct
solution how to build such a project with autotools.

If you try the port, please be aware that I created some cmake logic
to detect if a system has the libgee-1.0 or libgee-0.8-package
installed and sets the compilerflags accordingly. This is necessary
because of the unlucky decision of the gee-developers to do a
backwards version-number-change from 1.0 to 0.8. On debian jessie
there are still libgee-1.0-packages around. Without that logic it
would be impossible to build on debian older than stretch (testing).

Yours, Grindhold
