digitalmars.D.learn - Return ASCII value as uint

Hey,

I was wondering if D has a simple function to return the ASCII value of a
character as a uint, much like ord() does in php.

Thanks!

You could just assign the charachter to a uint variabel, that should work.

Shouldn't a cast be sufficiant?

char c = 'a';
uint i = cast(uint)c;

Yes, a cast would work, however I was wondering if there was an actual function
that I could use to grab the value while passing it to another function,
specifically this function:

saveItem.addAccelerator("activate",accelGroup,i,GdkModifierType.CONTROL_MASK,accelFlags);

That function contains the i variable from your function. Is there a simple
function, or should I use a cast?

Just cast it.  chars are just integers; you can freely cast between 
characters and integers.

A good general template function (will work for anything that can be explicity
casted to uint, including chars, doubles, and pointers):

uint toUint!(T)(T c) {
        return (cast(uint)c);
}

Well, that doesn't compile. Is the ! needed? Anyways, if I pass an "s" to that,
it should return the ASCII value (115 I think), right?

That ! is a typo.

I thought it was, works great without it!

Is there really any point using this when you can just cast when you need 
to?  OK, so it saves two characters where it's used....

<con>
It makes someone have to go lookup what toUint actually does.  Rather 
than being able to tell immediately by virtue of knowing basic D syntax.

<pro>
toUint(3+foo(x)) is a little easier on the eyes than
cast(uint)(3+foo(x)).
