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?
2. I was surprised to get all names equal... Seems that "names[i] = name"
actually copies a ref to the name. Is there another way to produce a copy than
"names[i][] = name"?
3. As you see, I individually set the length of each names[i] in the outer
loop. (This, only to be able to copy, else the compiler complains about
unequals lengths.) How can I set the length of all elements of names once and
for all?
4. Is there a kind of map(), or a syntax like list comprehension, to generate
array content from a formula? (This would here replace both loops.)
5. Seems there is no auto-conversion between char[] and string. Thus, I use
only char[], else I'm constantly blocked with immutability. But for this reason
I cannot use nice facilities to construct text expressions, like format().
Also, I need to convert every literal, even chars, when they must go into a
char[]. Grrr! Even to initialise:
Text text = to!Text("start text") ;
Hints welcome.
Thank you,
Denis
