Function std.string.abbrev

Construct an associative array consisting of all abbreviations that uniquely map to the strings in values.

This is useful in cases where the user is expected to type in one of a known set of strings, and the program will helpfully autocomplete the string once sufficient characters have been entered that uniquely identify it.

Prototype

string[string] abbrev(
  string[] values
) pure @safe;

Example

import std.stdio;
import std.string;

void main()
{
   static string[] list = [ "food", "foxy" ];

   auto abbrevs = std.string.abbrev(list);

   foreach (key, value; abbrevs)
   {
      writefln("%s => %s", key, value);
   }
}

produces the output: 

 fox => foxy
 food => food
 foxy => foxy
 foo => food
