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

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));
}


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));
}

Parameterized enum does not work

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:

function from argumen

t types !()(int), candidates are:
