Ada vs Eiffel

["Saša Janiška" <sjaniska@gmail.com>]

Hello,

I'm studying some subject and would like to start working on
accompanying desktop GUI application. My dev environment is Linux
(Debian Sid), but would like to be able to provide application for both
Windows & MAC OS.

Ada is already for quite some time on my radar, but recently I stumbled
upon some interesting application written using Eiffel
(https://www.eiffel.com/) language which looks quite interesting,
supports Design by Contracts etc.

However, it pushes just OOP paradigm, but it looks as simpler language
to learn/master with somewhat similar compiler licenses - expensive for
commercial apps and free when using GPL.[1] Both languages seems not to
attract too many open-source enthusiasts and not used in many FLOSS
projects, but providing bindings for GTK (although GtkAda does support
GTK3, while EiffelStudio is GTK2 only)...

Now, I'd like to hear from more experienced people here if You can share
some pro/cons between Ada & Eiffel?


Sincerely,
Saša

[1]  Frankly speaking, I'd like to write free application, but with the
possibility to eventually have some parts as close-sourced, although
without commercial interest.
