Thanks for the ideas, I've now reduced the size of the getWords()
function (even allowing for moving the imports to the top of the
file) to this:
WordSet getWords(string filename, int wordsize) {
string bareWord(string line) {
auto rx = ctRegex!(r"^([a-z]+)", "i");
auto match = matchFirst(line, rx);
return match.empty ? "" : match.hit.to!string;
}
WordSet words;
slurp!string(filename, "%s")
.map!(line => bareWord(line))
.filter!(word => word.length == wordsize)
.each!(word => words[word.toUpper] = 0);
return words;
}
Is this as compact as it _reasonably_ can be?
