The issue here is that, if all lines in a string should be indented, you can't use indentation stripping. Ruby 2.3 does this with its heredocs, and Python's dedent function also implements this behavior.<br class=""><br class=""></div>That doesn't quite capture the entire breadth of the problem with this algorithm, though. What you'd like to do is say, "all of these lines are indented four columns, so we should remove four columns of indentation from each line". But you don't have columns; you have tabs and spaces, and they're incomparable because the compiler can't know what tab stops you set. So we'd end up calculating a common prefix of whitespace for all lines and removing that. But that means, when someone mixes tabs and spaces accidentally, you end up stripping an amount of indentation that is unrelated to anything visible in your code. We could perhaps emit a warning in some suspicious circumstances (like "every line has whitespace just past the end of indentation, but some use tabs and others use spaces"), but if we do, we can't know which one is supposed to be correct. With the proposed design, we know what's correct—the last line—and any deviation from it can be flagged *at the particular line which doesn't match our expectation*.</div><div class=""><br class=""></div><div class="">Even without the tabs and spaces issue, consider the case where you accidentally don't indent a line far enough. With your algorithm, that's indistinguishable from wanting the other lines to be indented more than that one, so we generate a result you don't want and we don't (can't!) emit a warning to point out the mistake. With the proposed algorithm, we can notice there's an error and point to the line at fault.</div><div class=""><br class=""></div><div class="">Having the closing delimiter always be on its own line and using it to decide how much whitespace to strip is better because it gives the compiler a firm baseline to work from. That means it can tell you what's wrong and where, instead of doing the dumb computer thing and computing a result that's technically correct but useless.</div><blockquote type="cite" class="" style="margin: 15px 0px;"><div class="" style="margin-top: 0px; margin-bottom: 0px;"><div class="bloop_markdown" style="font-family: Helvetica, Arial; font-size: 13px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(254, 254, 254);"><p class="" style="margin: 15px 0px; -webkit-margin-before: 0px;">PS: If we’d get this feature in Swift, it would be nice if Xcode and other IDEs which supports Swift could show space characters that are inside a string literal (not other space character <- which is already supported), so it would be easier to tell what’s part of the string and what is not.</p></div></div></blockquote>That would be very nice indeed. The prototype's tokenizer simply concatenates together and computes the string literal's contents after whitespace stripping, but in principle, I think it could probably preserve enough information to tell SourceKit where the indentation ends and the literal content begins. (The prototype is John's department, though, not mine.) Xcode would then have to do something with that information, though, and swift-evolution can't make the Xcode team do so. But I'd love to see a faint reddish background behind tripled string literal content or a vertical line at the indentation boundary.</div><div class=""><br class=""></div><div class="">In the meantime, this design *does* provide an unambiguous indicator of how much whitespace will be trimmed: however much is to the left of the closing delimiter.
