Hello,
A few questions raised by a single func.
===================
alias char[] Text ;
Text letters = ['a','b','c',...] ;
Text[] nameSet (uint count , uint size) {
/* set of count random names of size size */
Text[] names ; names.length = count ;
Text name ; name.length = size ;
for (int i=0 ; i<count ; i++) {
for (int j=0 ; j<size ; j++)
name[j] = letters[uniform(0u,26u)] ;
names[i].length = size ;
names[i][] = name ;
}
return names ;
}
===================
1. In the inner loop generating name, I have found neither a way to
feed directly ints into name, nore a way to cast ints to chars using to!
(also found no chr()). So, I had to list letters. But this wouldn't work
with a wide range of unicode chars... How to build name directly from
random ints?
Can't you just use addition?
i.e. i = 0-25 mapped to letters a-z is cast(char)('a' + i)
If you are going for unicode, I'd suggest using wchar or dchar (which
could be directly cast from integers) to build the string, and then use
to!(char[])(widename);
Finally, I'd suggest accepting a dchar[] letters as a third optional
parameter in case someone wants names in a specific language.
