Ditched distutils in favour of dub. This is easier for me to
maintain and fits much better with the rest of the D ecosystem
I am not convinced by this, though cleary my feeling carry no
weight in decision making :-)
For building C, and C++ extension (and indeed Chapel ones) it
is assumed distutils will be used, allowing for:
python3 setup.py build
python3 setup.py install
SCons can do this but every one demands distutils. Can dub
really replace distutils for installing extensions as well as
building them? Will people installing extensions be prepared to
switch to a non -standard system? Whilst perhaps they should,
they won't. I fear that without a distutils installation, the
extension will never be installed outside the development team.
It's not the D community that must be convinced, it is the
As an addendum: not many people prefer to do non system type
things in C than a higher level language when time is money. So
the mindset is you build a C extension to address the worst bits
where Python's true colours shine through (ie when you are in a
tight loop within Python interpreter and not spending most of the
time in its C libraries. Or writing C glue to connect Python to
In my view, D is different. I would rather write in D than
Python, and to me it's much better Tor doing serious work. Even
for parsing a CSV I prefer it (although one could debate the
point). In any case D is not especially slower to write in than
Python (particularly when you include time spent getting the bugs
out), and in a decent number of cases it may be more productive.
So why bother with Python at all ? Better ecosystem for charting
and exploring data, and an interpreter is better suited generally
for certain kinds of tasks. Also in some areas more libraries,
which can be helpful to get a quick result, so that one can go
back and do it properly later.
It would be v helpful to have a Datetime conversion from D.
Looks like there is a macro for converting from ymd in
datetime.h, so I guess one could just write some code against
this API in C, D, or Cython and link it in with D so one can
transfer data structures over more easily.
