I don't think you can alias an object method directly; three methods I
know of:
---
struct Struct {
void run(int number) {
import std.stdio;
writeln("run ", number);
}
}
// Pass the object itself.
void func1(alias obj)(int number) if (isFunction!(obj.run)) {
obj.run(number);
}
// Pass the object and the name of the method.
void func2(alias obj, string method)(int number)
if (__traits(compiles, "obj." ~ method ~ "(number);"))
{
mixin("obj." ~ method ~ "(number);");
}
// Pass the method at runtime.
void func3(void delegate(int) f, int number) {
f(number);
}
void main() {
Struct obj;
func1!(obj)(1);
func2!(obj, "run")(2);
func3(, 3);
}
---
Also, you don't want to name something "Object"; the base class is called
Object -- the struct shadows it but you may run into some bug or confusion
later.

Generate documentation for mixin'd function?
Hi
I'm making an API for a web service, and have a small collection of
endpoints where I'd basically be creating copy+paste functions (a small
enough number that this isn't really that important for this project). I
thought I'd generate them via a mixin, but haven't seen that I can
generate documentation for the mixin'd functions with either ddoc or ddox:
---
string GenerateSimpleEndpoint(string endpoint, string type) {
return
"MyServiceObj " ~ endpoint ~ "(MyServiceObj service) {\n"
~ "service.addQueryType(" ~ type ~ ");\n"
~ "return service;\n"
~ "}";
}
/** My documentation goes here. No function shows up. */
mixin(GenerateSimpleEndpoint("endp", "EndpointType.MyType"));
/+
// If I write the function instead, everything's good.
MyServiceObj endp(MyServiceObj service) {
service.addQueryType(EndpointType.MyType);
return service;
}
+/
---
The doc generators don't see anything created via the mixin. `dmd -X` does
have the generated function, but its "file" is "file.d-mixin-172" rather
than just "file.d". My guess is that this is the problem for ddoc, but ddox
doesn't appear to use this json file so it would be a different problem.
Is this intended behaviour? Am I able to document generated functions?
Thank you for your time

If you separate initialization to a static this, you'll get a compile
error:
```
immutable uint256[78] pow10_256;
static this() {
// Error: mismatched array lengths, 78 and 2
pow10_256 = [
uint256(1UL),
uint256(10UL)
];
}
```
Or if you know that no element should be the object's init value, you
could do a static foreach to validate that at compile-time.
You could also generate the elements at compile-time (this could use some
improvement, and should be generalized so a single function can generate
fillers for your other arrays as well):
```
immutable uint256[78] pow10_256;
static this() {
// Uncomment this to view the generated code. Helpful for debugging.
//pragma(msg, GenPow10_256Initializer);
mixin(GenPow10_256Initializer);
}
static string GenPow10_256Initializer() {
import std.range : repeat;
import std.conv : text;
string code = "pow10_256 = [\n";
foreach(i; 0..78) {
code ~= `uint256("1` ~ '0'.repeat(i).text ~ `")` ~ ",\n";
}
code = code[0..$-2]; // Remove trailing comma.
code ~= "\n];";
return code;
}
```

VS release builds compile to native now by default; for easy Windows programming, you really can't beat C# and drawing the GUI (Windows Forms, not necessarily the new stuff). If the OP wants to learn what's needed for more complex GUI tasks (like for most non-simple applications), learning to build a GUI from source is kind of necessary though. If/when .NET Core becomes something people can rely on and are willing to try, I think we'll see more people using C# outside the enterprise; you get easy when you want it, power when you need it, native code generation on Windows, and OS portability.

I have the same issue on Windows 10, but Linux works; have you checked the
issue tracker yet?
It looks like just `dmd -J .\versioncheck.d` should work [I haven't tested
this properly with an actual string mixin, but I don't get that error this
way]. On Windows, dmd doesn't seem to like starting with the period.
So if it was in a different directory, instead of `dmd -J.\somedir` on
Windows you'd need to just do `dmd -Jsomedir`

I think I see what you mean; you interpret "use asserts, because enforce will be compiled out" to imply that asserts wouldn't be compiled out, correct? Since, in reality, both would be compiled out, it shouldn't matter what you use, so the docs shouldn't care. That makes sense. The documentation seems to assume the reader has certain expectations of assert and enforce[0], so each function expresses a different intention to the programmer; when I see `assert()` I expect those checks only in non- release mode; when I see `enforce()` I expect those checks regardless of the flags that have been set[1]. Placing `enforce` in a contract messes with that expectation. What language here would make more sense to you? Anything I can come up with is either awkward or pretty verbose. --Ryan [0]: The correct expectation, but that's not necessarily important when it's not explicitly described. [1]: So you can use enforce to validate user input, but never assert.

Contracts and assertions are removed for release builds, which means if you place an enforce in a contract, it's removed - but the same enforce placed in the function body would remain. You don't want the enforce stripped from the exe (if you are OK with that, it should be an assertion), so it shouldn't be in the contract. Use assertions to catch programming bugs, and enforce or try/catch for exceptions. If DIP 1006[0] is accepted, we'll have greater control over the removal of asserts and contracts in release mode.

I've actually thought about doing this to get rid of a bunch of if
qualifiers in my function declarations. `static interface {}` compiles but

FYI: The backquote gives you a WYSIWYG string: `c:\windows\system32`,

I don't have a network share available to test with, but:
Are you running with elevated privileges in the scheduled task? If so, do
you run as admin when trying manually? If you mount the share as a user,

You could try in the batch file, either adding
```
net use N: \\server\share\BACKUP /USER:
```
prior to running the exe (and "net delete" afterword), or try
"pushd \\server\share\BACKUP" to access the path (and make it the current
working directory). Use "popd \\server\share\BACKUP" at the end of the
script.

SO request you help on this. You're not using getopt in the sample; if you comment that line out, do you still have the problem? How are you passing arguments in Task Scheduler? You should be using the textbox for arguments, not the same one the application is passed in. Program/script: test.exe Add arguments: dryrun, run If that's correct, create a batch file that takes no arguments and calls your application and try running the batch file via Task Scheduler. If that fails, the application is probably trying to do something it doesn't have permission to do. If it succeeds, the task command is probably not set up correctly. --Ryan

The exception for dirEntries was reported as a bug here[1]; there is a
workaround listed on that page that silently skips directories it can't
read, but you'll need to modify it a bit to maintain a breadth search.
As to why your code stops after catching the exception, the try/catch
block does not place you back in the block that threw the exception, but
drops you off in the outer scope. You would need to place the code in some
sort of loop to run until all input was consumed in order continue past
the exception.

You could wrap the cast in a function to clean it up a bit:
void main() {
byte foobar = 12;
foo!byte((foobar + 1).b, (foobar + 22).b, (foobar + 333).b);
}
byte b(int n) pure {
pragma(inline, true); // Probably not necessary.
return cast(byte)n;
}
void foo(T)(T bar, T bar2, T bar3) {
import std.stdio : writeln;
import std.string : format;
writeln("%s, %s, %s".format(bar, bar2, bar3));
}

The only solution I can think of is never splitting a module in Phobos; the alternative would be to change the way the module system works (which seems to be what you want), and that's going to break everybody's everything.

You can do either a static import or renamed import. The static import requires using the fully-qualified name; renamed imports let you set a local name for the module. static import ui.widget; ui.widget.SomeWidget w; import mymanager = ui.manager; mymanager.uiManager m; For more information on modules see http://dlang.org/spec/module.html --Ryan
