How to make workable something like this:
struct S (T...) {
T args;
string arg_str;
foreach(i; args) {
arg_str ~ to!string(i);
}
}
void some_function(S s) { // here ... Error: struct S(T...) is
used as a type
s.args = [a, b, c];
string args = s.arg_str;
}

Oh, the "static if" ... for compile time evaluation; seems
unintuitive (no?) since data is encountered at run time.
But the types are known at compile time.

What is the best way to have a function sort an associative array

What is your way to import modules from other directory trees?
Here is my (incorrect?) ideal:
Given:
/home/user/library_directory/
Containing:
lib_one.d
lib_two.d
lib_interface.d
lib_interface.d source:
module lib_interface;
public import lib_one, lib_two;
Implementation in program /home/use
Any suggestions for using std.parallelism (like MPI for C/C++)
for server clusters? Alternatively, how might I use MPI with D?
How do you increase floating point precision beyond the default of 6?
example:
double var = exp(-1.987654321123456789);
writeln(var);
--> 0.137016
Assuming this result is only an output format issue and that operations are
still using double's 64 places, if var above is passed to a function, are
In the core.thread library, there is a method isRunning() which takes a thread.
To make code more portable, rather than use a system call or getenv(), how might
isRunning() be adapted to check if a program is running?
Ideally: isrunning(program_name);
Has anyone here succeeded with a dmd2.055 one-click install to Linux amd64?
Unlike the prior dmd2.0xx, I have no luck with dmd2.055 for amd64 installs.
I've
tried Debian, Fedora, and Suse.

Thank you, it works as planned, now as:

Recall that std.date used the following to retrieve a month in integer form (0

auto Now = std.date.getUTCtime();
writeln(std.date.monthFromTime(Now));
Using std.datetime, the following yields the abbreviated month name:
auto Now = Clock.currTime();
writefln("%s", Now.month);

writeln(m.hit);

Until recently, you could easily use std.regexp.search(target_string,
find_string), but regexp is apparently no longer in phobos. I seek a simple
substitute. std.algorithm.canFind might work, as
it is bool.
Maybe try something like:
foreach(str; strings)
foreach(fls; system_files)
15 matches
