digitalmars.D.learn - std.date / std.datetime

reply Richard Chamberlain <richard sunsetandlabrea.com> writes:
Hello,

I'm in the process of learning D, and to do so I'm converting some older code.

I need to print out the current local date and time, which is causing 
some difficulties because std.date doesn't seem adequate in this 
respect. I understand there is soon to be a replacement, std.datetime, 
which I suspect will be much easier.

When are we likely to see a new release which includes std.datetime?

If not relatively soon I presume the easiest thing to do is to download 
it myself and recompile the phobos library to include it. In which case 
there seems to be already a std.datetime with different functionality, 
is this used elsewhere in phobos? i.e. if I replace it with the new 
std.datetime is that OK?

Many thanks,

Richard

std.datetime is currently in Phobos' svn repository and will be in the next 
release.

Hi Jonathan,

I'm also stuck with the existing std.date and would want to try out your new
module std.datetime. Do you have any sense when the next release of Phobos is
going to be?

If not, what is the procedure to get a "development snapshot" of the latest
version of Phobos installed?

thanks,

I don't know. The last release was about a month ago, and the one before that 
was about a month and a half before that. I'm not aware of there being any hard 
and fast rules or plan about when releases are done. However, they tend to be a 
month or two apart.

The latest code can be found here: http://www.dsource.org/projects/phobos

However, you're going to have to have the latest druntime as well:

Thanks Jonathan.

I think I'll hang around for the official update.

Might it be worth putting in some infrastructure whereby people can use
a distributed DMD or GDC but have a current snapshot or perhaps latest
build of Phobos (where there is consistency between DMD/GDC on the one
hand and Phobos on the other).  This is actually one thing Go does
supremely well, you can pull the Mercurial snapshot and build the entire
system within about 5 minutes.  It makes it very easy to test new
stuff.=20

There has been discussion of D needing some sort of package management system. 
Perhaps that would deal with that issue. And maybe with dmd, druntime, and 
Phobos being moved over to git and github (which is currently being worked on) 
will make that easier. I don't know. However, I think that the focus of the dev 
team overall has been more on getting done than making it easier for people to 
get current development snapshots or know exactly what's going on with 
development at the moment. That's not to say that such things shouldn't be 
improved or that the dev team doesn't want to improve them, but there have been 
other priorities which have taken precedence. There's also a strong tendency
for 
things to get done because someone wants them done and takes the time to do 
them, and if there's no one who's motivated enough to do something, then it 
often doesn't get done in a timely manner.

You could always use the C functions, if you import core.stdc.time.  The 
ctime and strftime functions should do the trick.
