Extension methods in D?
Hey folks, I'm trying to get these bits of syntax to make sense to me:
S[] split(S)(S s) if (isSomeString!S)
{
...
}
and
string join(in string[] words, string sep)
{
...
}
(As seen in phobos/src/std/string.d)
As far as I can tell, this is…

std.algorithm.sorting fails with obscure errors when using Array!T and opSlice()
I'm sure I'm missing something obvious here - the rest of D (even the compiler errors) have been very sensible and easy to understand. I have a std.containers.Array of comparable structs and I'd like to sort it. the std.containers documentation…

std.json - A bit confused with TRUE, FALSE and NULL values
I was looking over the std.json library as part of program I am working on, and I'm a bit confused about how to get data out of JSONValues whose types are inferred as TRUE, FALSE or NULL.
For example, if I parse the following JSON:
{
"foo" :…

Phobos library function for converting a uint to binary string
Is there a Phobos function that converts an unsigned integer to a binary string? I've searched, but couldn't find one - just want to make sure I'm not reinventing the wheel by writing my own.

Does phobos (D's standard library) contain "endsWith" for string type?
I need a function to test if a string ends with some suffix. I can use 'lastIndexOf' for this task, but I wonder if there is a standard phobos' function?

D: Why is opIndex not const-qualified in the std.container.Array class?
I recently wanted to make use of std.container.Array and proceeded to create a class with a getter member function which returns a value from the Array class. I quickly realised that I was not able to const-qualify my getter, since opIndex is a…

I'm trying to instantiate a container full of Unique resources, in an attempt to ensure that when the container is destroyed, all items managed (owned) by the container are also destroyed, automatically and right then.
The following (non-Unique)…

Cannot resolve type for template function
I'm trying to code up something very simple in D, but I'm having a few problems with one of the standard library template functions (specifically, nextPermutation from std.algorithm).

D: Escaping spaces in a string
I have a string "foo bar baz", and would like to turn it into "foo\ bar\ baz". Short of the hand-hacking method (call split, then re-join with the appropriate separator), is there another way I can do this? Does something like a replace function…

How to detect if a function is annotated with @property
Is it possible using D's builtin traits and/or std.traits to detect whether a function (either within a class/struct or without) is annotated with @property? I know @property isn't really an attribute, but I thought __traits(getAttributes, ...)…
