Hey,
I'm struggling to find a way to achieve this. I've looked
through std.algorithm but didn't find anything.. Maybe I'm
blind.
What I would like to do is filter out all spaces in a string
and change the front letter to lower case:
string m = "My Capital String";
string lower = m
.filter!(c => c != ' ')
.<executeAt>!(0, c => c.toLower) // executeAt does not
exist
.array.to!string;
assert(lower == "myCapitalString");
or sth like
m.filter!(...)
.map!((element, int index) {
if (index == 0)
return element.toLower;
else
break; // stop since we are done manipulating
range
});
Anyway to do this?
No need for regular expressions. D is powerful enough without
them:
```
alias lowercased = (m, n) =>
m.take(n).asLowerCase.chain(m.drop(n));
```
