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

What are you trying to do?

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));
}
