A quick pass to flip `/.../` out of the alternatives and into the main syntax. Still needs a bunch of work. Also add some commentary on a regex with `]` as the starting character.
…n. Split out Proposed solution from Detailed design. Parallelize the structure a bit better.
This isn't actually used, as we convert to a DSL custom character class, and then use that consumer logic.
Convert AST escape sequences that represent a scalar value (e.g `\f`, `n`, `\a`) into scalars in the DSL tree. This allows the matching engine to match against them.
Fix a dead link and example.
Rather than matching and not advancing the input, we should always return `nil` to never match against the trivia.
Previously we would check for an empty array of members when deciding whether an initial `]` is literal, or if the operands of a set operation are invalid. Switch to checking whether we have any semantic members instead.
Fix trivia in custom character classes
Add availability to public, SPI, and test symbols.
This should be unreachable, let's make sure of that. Doing so requires generalizing the handling of LocatedError a bit.
Previously we would always parse a "change matching option" sequence as a group, and for the isolated syntax e.g `(?x)`, we would have it implicitly wrap everything after in the same group by having it do a recursive parse. This matched the Oniguruma behavior for such isolated groups, and was easy to implement, but its behavior is quite unintuitive when it comes to alternations, as e.g `a(?x)b|c` becomes `a(?x:b|c)`, which may not be expected. Instead, let's follow PCRE's behavior by having such isolated cases affect the syntax options for the remainder of the current group, including across alternation branches. This is done by lexing such cases as atoms (as they aren't really group-like anymore), and having them change the syntax options when we encounter them. The existing scoping rules around groups take care of resetting the options when we exit the scope.

Compiler tests triggered here: swiftlang/swift#42386 |
Tests now have flag `-disable-availability-checking` because XCTests always test the just-built modules, rather than the modules in the OS.
Add remaining availability annotations.

Friend PR: swiftlang/swift-experimental-string-processing#282. Also remove the `-enable-experimental-pairwise-build-block` flag when building regex modules as the feature is already on by default.
