Absolutely not, and frankly I resent the implication.
I'm looking at a space where (in my opinion) all existing designs are ugly and
inelegant and trying to find something better. There are *reasons* Swift 2
doesn't allow newlines in quote marks; I'm trying to address them, not ignore
them. There are nasty formatting problems; I'm trying to solve them, not
tolerate them. There are significant context-sensitivity issues; I'm trying to
fix them, not punt the problem to a syntax highlighter that is absent or
incorrect in half of our tools.
Here's a piece of code-generating code I once wrote, ported to this prototype:
https://gist.github.com/brentdax/8a8ee1f6028230f68ed85b7f3ebc95bf
(The actual code generation starts on line 93.)
And here's the same code in (beta-era) Swift 2:
https://github.com/brentdax/WebResponder/blob/master/WebResponderCore/WebResponderCore/codes2swift.swift
I think the new version is an improvement over the old. I think I like it
better than I would with `"""` or heredocs forcing things against the left
margin. I think it's nice that I can look at any line—out of context, random
access—and see which parts are string literals. I think if I want to add a doc
comment to each of the constants it generates, I have to do a little awkward
code shuffling, but the result is worth it:
for statusLine in statusLines {
code += " /// The HTTP \(statusLine.code) \(statusLine.message)
status, used with `HTTPResponseType.status`.
" \(statusLine.constant)
"
""
}
Overall, I find this code a lot more pleasant to read than it was in Swift 2,
and somewhat more pleasant than it would be with `"""` or a heredoc. Maybe you
don't agree; maybe you'd rather import some other language's warts. I
understand—those warts come with convenience advantages, and you might prefer
that convenience to the other things.
But at least have the basic respect for opposing viewpoints not to impugn my
motives because you disagree with me or don't like what I suggest. That is just
not nice.
