You're missing that `parse`'s parameter is `ref`. `splitValue.front` is

May I ask why you don't want to do that ?
In D you can call a function without args
Consider the following code
-
import std.range;
import std.conv;
import std.utf;
import std.algorithm;
auto test(R)(R s)
{
auto value = s.byCodeUnit;
auto splitValue = value.splitter('.');
parse!int(splitValue.front);
}
void main()
{
test("1.8");
}
-
This fails

Perhaps you didn't complete "dub build" without --nodeps
beforehand? You have to do that once, and it's still as

you might want to use __gshared data to avoid it being optimized

Is it better to collect all the tests and output the results

Is there a way to get the alias uint32_t instead ?
Nope. For the compiler uint32_t and uint are the same thing, this
is by design. Typedef can be used to create a separate type with
the same semantics as the type it's based upon:
alias uint32_t = uint;
struct Offset() {
uint32_t x;
uint32_t y;
}
// Introspect with:
void printStructInfo( T )( T info ) {
import std.stdio : writefln;
foreach (memb; __traits(allMembers, T)) {
writefln(typeof(__traits(getMember, info, memb)).stringof);
}
}
// Result is uint
Hi, I write a script that take a list of files from STDIN,
compute some stuff, and copy files with a new names.
I got 33k lines at input but got only 3k-5k in the destination

This is not append if I remove the .parallel() function.
What did I do wrong?
