horray!

i'm not sure if i got the new version, because the command line still 
says 'DMD .116' though i did get it from 
ftp://ftp.digitalmars.com/dmd.117.zip

one question, though. why doesn't the compiler stop compiling when it 
gives me warnings? shouldn't warnings just warn and still compile? 
*confused*

thanks.

Forgot to copy the linux one in, fixed now.

The warnings cause the compiler to stop with a non-zero exit code for those
who do automated builds. If it didn't, they'd miss the warnings as the
scroll off the screen.

Maybe there should be some kind of "release candidate"
procedure to the new zipfiles ? Or do we have to give
the MD5SUM of the zip of the DMD version we're using ? ;-)

"Fixed now" seems to imply it was changed *after* release ?

That effectively makes all warnings into errors which is very different than 
just showing warnings and letting the user do what they want to. Capturing 
output so that it doesn't scroll off the screen is covered in programming 
101 so I would assume people can deal with multiple comments.

How about aping the -Werror option of gcc ("make all warnings into 
errors") for use in automated builds?

I agree. Also, if someone is "responsible" enough to want warnings, they 
should be responsible enough to start fixing the warnings at the bottom 
of the list until the top of at list are visible.

DMD should produce as many warnings as possible (when the switch is 
turned on). Let the user worry about capturing the information and 
applying the appropriate fixes. ;)

This is great.  One less thing for Derek's build to worry about.  I'm a

Well, DMD only supports library linkages this way, but build still supports
library *and* object files.

  version(build) pragma(link, "somefile.obj");

  version(build) pragma(link, "libone.lib", "libtwo.lib");

Please let me know if you need help here.

I guess that  {struct aaA} can be used
"as is" for placing elements in static section.
So lookup procedure can be built on the same principles
as lookup in the heap...

Cleaning out the attic of lots of minor bug fixes.



Mango produced three or four of the following warning types, which appear to be
bogus: "warning - function mango.io.FileConduit.FileConduit.copy no return at
end of function"

# FileConduit copy (FilePath source)
# {
#     auto FileConduit fc = new FileConduit (source);
#     super.copy (fc);
#     return this;
# }               


Moving along, Mango conjures up a thicket of "implicit conversion of type int to
bit can cause loss of data". These are caused by a variation upon this kind of
statement:

# bool x (int y, int z)
# {
#     return y > z;
# }


Then, there's a few similar warnings where the sign bit is lost through a
legitimate conversion. There's also a few narrowing conversions when interfacing
with Win32 functions, and so on. The latter are occasionally related to enum
specifications, which could be changed.

All in all the warnings found one bug, caused me to cleanup the 'sign' of a few
declarations (potentially better codegen), and pointed out that various methods
in std.date return a 64-bit long instead of something much smaller (how many
hours /are/ there in a day? :-)

Definately worthwhile, IMO. I could understand if some complained about "not
seeing the forest for the trees", but that's life with a type-system of this
nature.

I do wonder if there's any value in filtering the warnings somehow. For example,
the "int to bit" conversion for returns is one of those "idioms" that Walter
talks about; and Mango produces lots of 'em! But then we'd perhaps have to get
into warning levels? Oh well.

Thanks, Walter. I think this was absolutely worthwhile.

Hmmmm. I figured it was just the implicit try/catch (via the 'auto') that was
causing the problem. Indeed, temporarily removing the 'auto' causes the warning
to be inhibited. Don't know what to tell you about this one.


I was going to post other samples from Mango that produce the same error, but
closer inspection revealed the warning was actually correct. Those examples are
thread workers, with try/catch around the body which contains an embedded return
~ said workers don't have a return at the end, which they perhaps should ~ some
more subtle bug-fixes to chalk-up for warnings?

Excellent.

Making library distribution simple just got a whole lot simpler:

1) Store source code in "src/mylibrary/mylibrary.d"
2) Put libraries in "lib/mylibrary.lib"
3) compress all this to .zip
4) Users of the library decompress this archive to d:/path/to/dmd

Under such a scheme, projects that wish to use the library do not 
require so much as a single compile switch.

The trick is getting a convention into place. :)

Indeed!  I always thought that there should be a command to link a library 
without having to use the command line.  Now we can put the pragma(lib) 
command in our import modules.  Then, just import and everything works.

And the abstract class keyword does EXACTLY what I've been wanting to do for 
a long time!  No more private ctors to make base classes 
un-instantiate-able!

This is quite a juicy release.
