Congratulations!
It looks like an immense amount of work.
This line is very interesting:
It looks like an immense amount of work.
This line is very interesting:
- Use Zig toolchain as default backend C compiler (bundled into the delivery package).
Can you expand a little bit on it?

Hi Alejandro,
Zig is a new programming language whose goal is to replace C.
But the Zig project also contains a toolchain to compile
C code (based on clang compiler's code), and can even do
cross platform compilation (although I did not try it for
the Gobo Eiffel compiler yet). So instead of using say
'gcc ...' to compile the C code generated by the Eiffel
compiler, the command will be 'zig cc ...'. Of course this
should be transparent for the Eiffel programmer. The reason
why I work on this integration in Gobo Eiffel is first the
fact that it can be used on all mainstream platforms without
requiring the Eiffel users to have to install a C compiler
(Zig is included in the Gobo Eiffel package). Second, as
mentioned above, it allows cross platform compilation, which
is something I might work on in a next version of Gobo. Third,
the Zig toolchain has a caching mechanism which means that
if a C file has not changed, its object file will be available
in the cache and will be reused, hence avoiding a recompilation
of this file. I saw C compilation time improvements thanks
to this caching mechanism.
