Oh, sorry for misleading people.

AdaCore's ASIS still works, their own implementation to deal with modern
language versions.

I find libadalang a bit distressing, mostly because of the extensive
reliance on external Python utilities: from REQUIREMENTS.dev,

Mako==1.0.1
PyYAML==3.11
Sphinx==1.3.1
coverage==3.7.1
enum==0.4.6
enum34==1.1.2
psutil==3.4.2
sphinx-rtd-theme==0.1.9
funcy==1.7.1
-e git+https://github.com/AdaCore/langkit.git#egg=langkit
docutils==0.12
autopep8==1.2.4
yapf==0.16.0

and Quex.

Of course, the libraries required for GPS make a long list too.

Also, there are also difficulties using the latest Github libadalang,
which relies on a recent libgpr (more recent than the one I included
with the macOS GCC 8.1.0, but OK with GNAT CE 2018).

I suppose I just have to man up, bite the bullet, ...
