17.1 How to activate the extended GNAT Ada superset ¶
There are two ways to activate the extended GNAT Ada superset:
pragma Extensions_Allowed (On)
As a configuration pragma, you can either put it at the beginning of a source
file, or in a .adc file corresponding to your project.
- The
-gnatX command-line option will
activate the curated subset of extensions.
Attention: You can activate the experimental set of extensions
in addition by using either
the -gnatX0 command-line option, or the pragma Extensions_Allowed with
All_Extensions as an argument. However, it is not recommended you use
this subset for serious projects; it is only meant as a technology preview
for use in playground experiments.
