[Issue 8682] Can't install DMD 2.060 on OS X 10.6.8
http://d.puremagic.com/issues/show_bug.cgi?id=8682 --- Comment #5 from Jacob Carlborg d...@me.com 2012-10-23 23:29:21 PDT --- (In reply to comment #4) Jacob, I tried the installer and it seemed to work fine. I was able to compile and run a D program. It seemed to put the dmd compiler in my /usr/bin directory. It did not put rdmd there. Running dmd or /usr/bin/dmd worked fine but rdmd and /usr/bin/rdmd did not work. I guess that rdmd wasn't available when the installer was created. Thank you. I am glad to have something that works. Out of curiosity, what did you do? I just built the installer on Mac OS X 10.6. I would guess that means the installers created on Mac OS X 10.7 or later aren't backwards compatible, or there's a missing flag or similar. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
[Issue 4563] [module system] Error messages for missing package or missing name

This is the only test-case left to fix in this Issue (the others seem to be
fixed).
This is the current situation:
// Case#1
import std.bitmanips: bitfields;
void main() {}
test.d(1): Error: module bitmanips is in file 'std\bitmanips.d' which cannot be
read
import path[0] = C:\dmd2\src\phobos\
import path[1] = C:\dmd2\src\druntime\import\
import path[2] = C:\leonardo\d_bugs\
import path[3] = C:\dmd2\windows\bin\..\..\src\phobos
import path[4] = C:\dmd2\windows\bin\..\..\src\druntime\import
// Case#2
import std.bitmanip: bitfield;
void main() {}
test.d(1): Error: module std.bitmanip import 'bitfield' not found, did you mean
'template bitfields(T...)'?
// Case#3
import std.math: foo;
void main() {}
test.d(1): Error: module std.math import 'foo' not found, did you mean
'function fma'?
The Case#1 probably needs a better error message.
The messages in cases #2 and #3 seem acceptable, it's not bad. But they
sub-optimal, in Case#3 this seems better:
test.d(1): Error: name 'foo' not found in module std.math, did you mean
function 'fma'?

test.d(1): Error: module bitmanips is in file 'std\bitmanips.d' which cannot
be
read
The Case#1 probably needs a better error message.
Yes, it can be:
test.d(1): Error: module bitmanips not found in package 'std'
However what if the module is not in any package? Example:
import bitmanips; void main() { }
= test.d(1): Error: module bitmanips is in file 'bitmanips.d' which cannot be
read
What should we do here?
test.d(1): Error: name 'foo' not found in module std.math, did you mean
function 'fma'?
I would replace 'name' with 'symbol' here.

(In reply to comment #8)
Consider (assuming A has an int-accepting ctor):
A object = A(1);
// or
auto object = A(1);
In here the name of the type being constructed appears in clear, so there's no
chance for a potential confusion. The code currently works, as it should.
Consider:
A object = 1;
Again the type being constructed appears in clear. The code works in a
function
but not at top level. It is a bug that it doesn't work at top level, because
the equivalent construct A object = A(1) does.
Now consider:
void fun(A) { ... }
fun(1);
In here there's no explicit mention of A in the call, which makes this case
qualitatively different from the ones above. Currently the compiler rejects
the
code and I think it does very well so. Implicit conversions on function calls
is unrecommended in the presence of function overloading, and essentially C++
made a mistake about it that it has later partially fixed with the explicit
keyword. We won't repeat that mistake.
Implemented.

[Issue 8143] Safe std.conv.to enum conversion

So the question is, is this going to be a problem? If yes, should we use approxEqual for floating point comparisons? By far the main purpose of enums is with integral values (ints, uint, chars, etc), to be used to enumerate something or as bitfields. Using float/double/real enums is supported in D, but it's not common. Using approxEqual is suboptimal, using std.math.feqrel is better. but all approximate floating point comparisons have their quirks and limits. Backing-in one solution is not a good idea. Or maybe we should simply ban using std.conv on enums that have a floating point base type? What about user-defined floating point types, or a double wrapped in a struct with an alias this? I think refusing conv on built-in floating point types is an acceptable solution to avoid most troubles. Other cases like wrapped doubles are left at the care of the programmer. I'd say there is nothing wrong with using floats as enums. It's rare because it's new (C++ only supported integral up to now). In C++, I've seen integral based enums used to index arrays which contained the actual payload (floats, strigns, others). Now we don't have to do this anymore. The *real* issue (IMO) is only when converting *back* from float to enum, which (IMO again), is plain too dangerous to realisticly assume we can support. I'd rather have float-to-enum always fail, personally. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Or alternatively require an additional alias parameter for the comparison
function in case of floats?
E.g.
enum EF : float { C = 4.9 }
float f = 4.9;
static bool compFunc(float lhs, float rhs) { ... }
EF en2 = to!(EF, compFunc)(f);
Since conv.to will already do the work necessary to 1) find the matching
member, 2) ensure there's only 1 matching member, I think customization like
this might be friendlier than just rejecting conversion.

Ok, I'll implement a pull and see what others think about it.
(Unrelated: do you know why D error messages don't have an ending full stop
.

GCC and DMC don't add a period either. I think it's purely accidental, some
tools do, others don't (and sometimes it's mixed). I don't mind such issues
though. Personally I worry much more about things like this:
void main()
{
void function(int x, int y, float z) funcC;
void function(int x, float y, int z) funcD;
funcC = funcD;
}
Error: cannot implicitly convert expression (funcD) of type void function(int
x, float y, int z) to void function(int x, int y, float z)
It would make it much easier to debug such cases if the error spanned multiple
lines and aligned the types, for example:
Error: cannot implicitly convert expression (funcD) of type
void function(int x, float y, int z) to
void function(int x, int y, float z)

http://d.puremagic.com/issues/show_bug.cgi?id=8886 --- Comment #2 from Don clugd...@yahoo.com.au 2012-10-24 10:57:37 PDT --- To clarify: When I say it won't work in general, the problem is things like: a b c d e f If a and b are pointers to the same memory block, then a b is OK, and this expression means: a b isInside(c..e, d..f) but if a and b are different pointers, then it would be: isInside(a..c, b..d) e f which is OK as long as e and f are in the same memory block. then there is an explosion of possible cases, and many similar things _still_ aren't handled ( eg, a1 b1 c1 d1 a2 b2 c2 d2, why isn't this recognized as two isInside operations?) So the rule is simple: they have to be part of a single or || expression. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

I think we can do even better: import foo.bar.doo; Now it's test.d(3): Error: module doo is in file 'foo\bar\doo.d' which cannot be read If 'foo' doesn't exist the error should probably be: test.d(3): Error: package 'foo' not found If 'bar' doesn't exist it should be: test.d(3): Error: package 'bar' not found in package 'foo' If 'doo' doesn't exist: test.d(3): Error: module 'doo' not found in package 'foo.bar' Also, we might consider doing informative spellchecker errors, e.g.: import std.stddio; test.d(3): Error: module 'stddio' not found in package 'std', did you mean 'stdio'? The above should probably try finding D modules that are similar to 'stddio', read their module declaration (because it might be different from the filename), and if the module declaration is similar to 'stddio' it should print that module name as a recommendation. import stdd.stdio; test.d(3): Error: package 'stdd' not found, did you mean 'std'? Here we might try finding non-empty folders with .d or .di files named similarly to 'stdd' and recommend such a folder.

What's the bug? I don't understand. How can arrays have no opEquals yet this assert(bar.data == foo.data); compiles? Syntactically there is opEquals and it checks whether each element is equal to the corresponding other element. And the opEquals generated by default should for each member call opEquals if it exists. Otherwise it falls back to bit-wise equality. Why should it be different from this? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

(In reply to comment #15)
Ah it took me a while to realize you were looking for CTFE ability.
Sorry for not being more clear.
Another significant test case, this is useful in many simulations and games, to
write safe tables and start conditions:
enum Code : char { A='A', B='B', C='C' }
void test()
{
...
const code = to!(Code[][])([ABCCBA, BBAA]);
with (Code)
assert(code == [[A, B, C, C, B, A], [B, B, A, A]]);
}
The main problem with this is that you receive conversion errors only at
run-time, and in D the problem with array compile-time constants is that the
compiler re-creates them every time where you use them. So they are not so
useful.
--
Unfortunately this is not yet allowed because to!() is not pure:
immutable code = to!(Code[][])([ABCCBA, BBAA]);

This code asserts:
import std.algorithm;
void main()
{
assert(commonPrefix(Пиво, Пони)== П);
}
This is because a portion of the code point following 'П' is returned, because
the code units at the beginning of the next code point match, and commonPrefix
fails to take that possibility into account. It basically operates on code
units right now for matching string types rather than operating on code points
as it should.
