Hi,

Should following coding work?

string lpad(ubyte length, long n)
{
	import std.string: rightJustify;
	import std.conv: to;
	return rightJustify(to!string(n), length, '0');
}
	
enum lpad14(long n) = lpad(14, n);

void main()
{
	lpad14(123);
}

There is following error from dmd:

source\app.d(12): Error: template app.lpad14 cannot deduce function from argumen
t types !()(int), candidates are:
source\app.d(8):        app.lpad14(long n)

Kind regards
André

OK I probably see it now :):

import std.stdio;

string lpad(ubyte length, long n)
{
    import std.string: rightJustify;
    import std.conv: to;
    return rightJustify(to!string(n), length, '0');
}

enum lpad14(long n) = lpad(14, n);

void main()
{
    writeln(lpad14!(123));
}

However this is only for compile time, if you want runtime version you need something like this:

import std.stdio;

string lpad(ubyte length)(long n)
{
    import std.string: rightJustify;
    import std.conv: to;
    return rightJustify(to!string(n), length, '0');
}

alias lpad14 = lpad!14;

void main()
{
    writeln(lpad14(123));
}

Thanks a lot.

Kind regards
André
