Use the getchar() function.

Re: How can you call a stored function in an AA with proper number of arguments converted to the proper type?

Thanks that is clever. Never would have thought of that. Thanks a

How can you call a stored function in an AA with proper number of arguments converted to the proper type?
Here's the basic code I'm playing with:
struct MyCmd
{
Variant func;
// Has other members.
}
MyCmd[string] functions_;
void addCommand(T)(const string name, T func)
{
MyCmd cmd;
cmd.func = Variant(func);
functions_[name] = cmd;
}
void process(string[] args) // args is only available at runtime.
{
const string name = args[0]; // Name of the command
if(name in functions_)
{
MyCmd cmd = functions_[name];
cmd.func(/*Call with proper number of arguments converted to
the proper type*/);
}
}
I initially got idea from the D Cookbook Chapter Reflection:
Creating a command-line function caller. But the code has to
reside in the same module as the functions it will use.
So I arrived at this code but can't figure out how to call the
actual stored function.
Thanks!
Re: Get current date and time with std.datetime
On Thursday, 30 June 2016 at 21:18:22 UTC, Luke Picardo wrote: Why is it so hard to simply get the current date and time formatted properly in a string? There are no examples of this in your documentation yet this is probably one of the most used cases. To get the current time, use Clock.currTime. It will return the current time as a SysTime. To print it, toString is sufficient, but if using toISOString, toISOExtString, or toSimpleString, use the corresponding fromISOString, fromISOExtString, or fromSimpleString to create a SysTime from the string. auto currentTime = Clock.currTime(); auto timeString = currentTime.toISOExtString(); auto restoredTime = SysTime.fromISOExtString(timeString);

As a workaround, you can set version to Linux yourself:
version (linux) {
version = Linux;

void main() {
version (Linux) {

writeln("Linux worked!");

That's interesting that will help. Thanks for that!

Since that time, we've standardized on capitalization for everything, but 'linux' lives on. I would like to see 'Linux' introduced for consistency and to avoid errors like yours (a bug lived in Phobos for a long time because of this) while maintaining 'linux' for backwards compatibility. Thanks, that makes sense. It would be nice if Linux could be introduced. I'll just have to remember from now on. Thanks again!
Why is Linux the only OS in version identifier list that has a lowercase name?
So I was just testing some code and couldn't figure out why it
wasn't working. My version block looked like this:
version(Linux)
{
...
}
Looking at the list(unless I'm missing something) Linux is the
only OS that is lowercase. I'm guessing most people use Posix
instead and never encounter this problem.

Duration at runtime
I'm confused by the following:
import std.stdio;
import std.datetime;
void main()
{
string unitType = "seconds";
auto seconds = 1;
// auto myDur = dur!(unitType)(seconds); // Error unitType can't
be read at compile time.
auto myDur = dur!("seconds")(seconds); // Compiles why?
}
How is seconds able to be read at compile time but unitType
cannot?
Thanks!

Re: Will D have a standard cross platform GUI toolkit?
On Thursday, 26 February 2015 at 18:20:12 UTC, Rinzler wrote: Hello, I was wondering if D will have a standard cross platform GUI toolkit. I think that any modern language should provide a cross-platform GUI toolkit. I know that there are some GUI toolkits, but are there cross-platform? Are there serious works? That is, will them always be supported and evolve along with the D programming language? I think that having bindings of a GUI toolkit for a programming languages can be useful, but they have to be well supported. Will QT support D programming language? I really love the Qt framework (except from the fact it's not open source, as far as I know), even though I have not used it a lot. I have to admit that I love D, even if I did not start programming with it. It seems it combines the most useful things of C++ and Java, which are my favourite programming languages. Maybe there are other questions already in the forum, since I am new, I don't know, but a new question, more up to date, can also be useful. Thanks! I can't believe no one has mentioned Dlangui https://github.com/buggins/dlangui.
