I can ask, but given that the Xenial final freeze is on 24. April 
(release on 26.) and changing compiler versions that late in the 
cycle is potentially dangerous, I guess there is only a slim 
chance of success... On the pro-side is that having a beta 
compiler in the LTS release is undesirable, but even then I need 
to find an Ubuntu developer who does have time to do the sync and 
get the feature-freeze-exception. LDC FTBFSing on armel in Debian 
(and not entering testing due to that at time) is also an issue 
:-/

That sounds very cool.  I'm very grateful that you are doing 
this work; it's going to save me my usual from-source install, 
and looks like it opens the gates for a bunch more D code 
getting into the Debian + Ubuntu universe.


Yes, that's the plan - for this to happen, we need some additions 
to dub though, to search in common global paths for packages. I 
opened bug 
https://github.com/D-Programming-Language/dub/issues/811 for 
that. Until that's fixed, I can't package more D code using dub 
(and adding debhelper bits also depends on this being resolved).


Curious question: what's the Debian policy these days on what D 
compiler should be used to build D packages?


There is no real policy, at least I have found none. But from my 
tests, ldc simply crashed right away when trying to compile, 
later it wasn't able to process some code gdc had no problems 
with (I haven't tried the upcoming release). Since the GNU 
Compiler Collection is Debian's default compiler, I have set the 
compiler dependency of dub to gdc | ldc | d-compiler, so gdc is 
preferred, but replacing it with any other compiler will work too.


And has dub's config been tweaked accordingly in terms of which 
compiler it prefers to use ... ?


I didn't touch that, since dub seems to automatically find the 
right compiler. The preference seems to be dmd >> gdc >> ldc2, 
which looks sane to me.


It's really bad that GDC isn't part of the official GCC yet, and 
the standard libraries differ so much between the compilers 
(mainly due to phobos progressing very quickly).


For Debian Stretch I assume the situation will be much better 
though :-) (given the state of the LDC and GDC Git repos).

Well, this makes useful have dub in both repositories,

dub on their system. If the last release is needed for any

1-2 day to update dub deb packages after dub release. The deb 
package is not a problem because we use the same package name, 
and the version shouldn't be a problem too, the newer version

Yes.

$ dpkg --compare-versions "0.9.25-0" gt "0.9.24-1ubuntu1" && 
echo "greater" || echo "NOT greater"


As long as you keep the Debian revision at 0, everything is fine 
and there should be no conflicts, if the binary package names in 
Debian and your repo match. Please just don't increase the Debian 
revision to something bigger than zero, that can result in 
breakage.
You could use a revision like "-0~1" or "-0.1" when making 
changes to the package without a new upstream releases.
But that seems to be the case already, so there's no problem here 
:-)

Command line utilities for tab-separated value files

[Jon D via Digitalmars-d-announce]

Hi all,

I've open sourced a set of command line utilities for 
manipulating tab-separated value files. They are complementary to 
traditional unix tools like cut, grep, etc. They're useful for 
manipulating large data files. I use them when prepping files for 
R and similar tools. These tools were part of my 'explore D' 
programming exercises.


The tools are here: https://github.com/eBay/tsv-utils-dlang

They are likely of interest primarily to people regularly working 
with large files, though others might find the performance 
benchmarks of interest as well (included in the README).


I'd welcome any feedback, either on the apps or the code. 
Intention is that the code be reasonable example programs. And, I 
may write a blog post about my D explorations at some point, 
they'd be referenced in such an article.

Jup - the biggest issue is that GDC and LDC are lagging behind 
the proprietary DMD compiler, especially in terms of supporting a 
more recent Phobos version. The latter makes many things 
buildable only with DMD, which won't be found in any mainstream 
Linux distribution (no free software).

Depends on the release cycle of Debian and Ubuntu. Generally, 
once software is in stable, it will only receive security fixes, 
and no further upstream versions will be added. That is part of 
the stability promise we give to users. Every new upstream 
release might include changes in behavior, breaking things or 
introducing new bugs.


That being said, new upstream releases can be made available via 
backports, if there is demand for it (it's relatively easy, if 
the code compiles with the older GDC release in stable at that 
time).


The Ubuntu Xenial (16.04) release (due in April) will have dub 
0.9.24, and Debian Stretch (9), which will likely be released in 
spring next year, will have whatever dub version is current then 
(or if the dub developers prefer a certain version for stable, 
that version).


Cheers,
  Matthias

Hello!
I am very new to the D community and just recently finished a 
project in D, which I want to make available in Debian (reason 
for choosing D was mostly its speed and similarity to C++ and C, 
making a very shallow learning curve for someone knowing these 
languages. And porting Python code to D was incredibly easy. I'll 
likely blog about my experience with D).
