digitalmars.D.learn - rdmd problems (OS X Leopard, DMD 2.052)

reply Magnus Lie Hetland <magnus hetland.org> writes:
Hi!

When I installed DMD 2.051 on my OS X boxen, the rdmd executable didn't 
work. I saw others have similar problems online, and concluded that it 
must have been compiled for a more recent version of OS X (Snow 
Leopard, I guess) without the necessary compatibility flags.

I found the rdmd sources online [1] and compiled them myself. (Luckily, 
the other binaries work just fine.) No problems.

Now I'm trying to get DMD 2.052 to work. Same issue with the rdmd 
executable. I tried to compile the same rdmd.d file with the new 
compiler/stdlib, but that failed.

$ dmd rdmd.d
std.contracts has been scheduled for deprecation. Please use 
std.exception instead.
std.date and std.dateparse have been scheduled for deprecation. Please 
use std.datetime instead.
rdmd.d(34): Error: std.regexp.split at 
./../../src/phobos/std/regexp.d(498) conflicts with std.string.split at 
./../../src/phobos/std/string.d(69)
rdmd.d(34): Error: function std.regexp.split (string s, RegExp pattern) 
is not callable using argument types (string)
rdmd.d(34): Error: expected 3 function arguments, not 1

I'm sure I can fix this myself -- but I'm guessing there must be a more 
recent version of the rdmd sources somewhere, assuming that the binary 
in the distribution was compiled with dmd 2.052...? The version in the 
trunk at dsource.org seems to be three months old...

For now I just compiled the rdmd.d from dsource.org with dmd 2.051, and 
use that with dmd 2.052. As rdmd is basically an independent entity, I 
guess that should work well, but this isn't exactly user-friendly 
(i.e., having to replace one of the binaries in the distro with one 
compiled with an older compiler, using sources obtained elsewhere... 
:->).

Not sure if I'm missing The Way to Do It[tm], or if perhaps I should 
submit an issue about this?

The source repo recently moved over to github: 
https://github.com/D-Programming-Language

That said, the 3-month-old version is still the latest version. 
Unfortunately, rdmd doesn't seem to have gotten much attention lately. I've 
had a few patches for it sitting in bugzilla for a number of months. (Not 
that I'm complaning, I realize there's been other priorities.)

Actually, if you want, you can grab a version of rdmd.d with my patches 
applied here:
http://www.dsource.org/projects/semitwist/browser/trunk/rdmdAlt.d

(Yes, it is 4 months old, and I can do the match: 3 < 4, but this *is* the 
same as the latest official version just with my patches applied: The latest 
official commit to rdmd.d was one of my patches (albiet slightly modified, 
IIRC))

However, the latest version of DMD I used this with was 2.050, so it might 
still need some updating for 2.052.

I see. Kind of surprising, given that rdmd is distributed in the 
official DMD zip file. But, yeah, no complaints. :)

Hm. Are most minor releases of DMD backward-incompatible? (Sort of a 
scary prospect to me, at least...)

It used to be fairly common for little things to change, but it's becoming 
much less and less common (And, as you've seen, when they do change, they're 
generally very trivial to fix). These days there's typically only these 
three cases where something might break:

A. Someone's code is accidentialy relying on a bug in DMD or Phobos, and 
that bug gets fixed. Not really a frequent occurrance.

B. Certain parts of Phobos are still somewhat in flux (only for D2 though). 
For instance, std.xml is definitely going to get completely replaced.

C. The occasional regression. (Which is less and less common these days, 
because of both an extensive test suite running on multiple OSes and because 
we now have a beta mailing list with people who test each release candidate 
before it's actually relesed.)

We used to have occasional breking changes in the language itself (in 
D2-only), since D2 was the deliberately the "development" branch rather than 
the "stable" branch that D1 has been, but D2's language spec is pretty much 
finalized now.

I just realized I didn't give a direct answer to your question: I'd say that 
most minor releases of DMD are *not* backward-incompatible.

Humm. I'm still using the rdmd I had (it seems to work, so as long as I 
have already compiled it... ;)

However: I'm a bit baffled by the --shebang option. What's its purpose, 
really? If I use rdmd without it in a shebang line, it seems to work 
fine. If I *do* use --shebang, the code doesn't seem to be 
compiled/executed at all...

It seems like it interprets args[1] as a single string containing all 
the arguments, splitting it into separate items. That seems well an 
good -- except (in OS X, at least) it doesn't seem to be needed (I get 
my arguments just fine without it, and the shebang-line switches work 
well) ... and it doesn't seem to work (that is, with --shebang, nothing 
happens).

Any thoughts on this?

Say you have a file "myscript", that starts with the line



If you run this as

    ./myscript --hello --world

then the args[] received by the interpreter program looks like this:

    args[0] = "/path/to/interpreter"
    args[1] = "--foo --bar"
    args[2] = "./myscript"
    args[3] = "--hello"
    args[4] = "--world"

This is the case on every shell I've tried on Linux, at least.  So if you 
have multiple rdmd options, it should in principle need --shebang to know 
that it is being run in a shebang line, so it can expand args[1].

I don't know why it works without --shebang for you, though. :)

Perhaps he's not passing any arguments to rdmd.

Let me first clarify: By "nothing happens", I really mean that. When I 
supply --shebang, the code isn't compiled, and nothing is run. Running 
the script becomes a no-op.

As for your example: The switches to rdmd *don't* appear in args for 
me. So for example, if I have



... as the shebang line, rdmd finds and passes the -unittest switch to 
dmd (my unit tests work). I get no problems when I add more switches 
either (i.e., rdmd doesn't complain). But, as far as I can see, none of 
these end up in args. (Or are we talking about different things here?)

Instead, args[0] contains the full path to the temporary executable 
built and run by rdmd, and args[1..$] contain any arguments I supplied 
when running the script.

The fact that --shebang borks the whole execution seems like it must be 
a bug. As for the rest of the behavior, it seems pretty useful to me, 
but perhaps OS X-specific? (That would be odd, but who knows...)

Haha, cool :D Yeah, too bad the project died. Oh, well -- at least we tried :)

Yeah, I've been looking for a more "close to the metal" language to 
complement Python for a looong time (using C and C++ when I had to -- 
and sometimes Java or Cython and what-have-you). At the moment I'm 
hopeful that D might be what I've been looking for. Loving it so far :)

(Still using Python, though. Just came out with a new Python book, 
"Python Algorithms", last fall ;)
