I want to use the Porter stemming algorithm.

There's a D implementation here: https://tartarus.org/martin/PorterStemmer/d.txt

The main public function's signature is:

char[] stem(char[] p, int i, int j)

But I work entirely in terms of strings (containing individual words), so I want to add another function with this signature:

string stem(string word)

I've tried this without success:

     public string stem(string word) {
         import std.conv: to;

         char[] chars = word.to!char[];
         int end = chars.length.to!int; >          return stem(chars, 0, 
end).to!string;
     }

Here are just a few of the errors:

src/porterstemmer.d(197,13): Error: cannot implicitly convert expression s.length of type ulong to int src/porterstemmer.d(222,9): Error: cannot implicitly convert expression cast(ulong)this.m_j + s.length of type ulong to int src/porterstemmer.d(259,12): Error: function porterstemmer.PorterStemmer.ends(char[] s) is not callable using argument types (string) src/porterstemmer.d(259,12):        cannot pass argument "sses" of type string to parameter char[] s

Your code and errors seem to be not related.
