58859f5699 [SourceKit/CodeFormat] Update indentation for braceless multiple trailing closures. 2020-05-06 01:56:41 -04:00

e01c1a1579 [SourceKit/CodeFormat] Get 'trailing' indentation to work in more places and fix a bug where multi-line string indentation was modified.
E.g. if/guard condition patterns are column-aligned, but hitting enter after
the ',' below wasn't column-aligning the next empty line:

guard let x = Optional(42),
// No indentation added here after enter

Also the isTargetContext() check takes a start and end token location, but
wasn't accounting for the end location pointing a multiline string, so we
weren't walking into such nodes. This meant we didn't realise the target
location was within a multiline string in some cases, and we ended up
interfering with whitespace in its content.

19d6effc5e [SourceKit/CodeFormat] Column-align multiple patterns in catch clauses.
Catch clauses now support mutliple patterns. Like 'case' patterns, these
should be column-aligned if split across multiple lines.

do {
  ...
} catch MyErr.a(let x),
        MyErr.b(let x) {
  print("hello")
}

2a93296fb6 [SourceKit/CodeFormat] Simplify ContextOverride a little, and only propagate ContextLocs when necessary.
We don't actually need to set a ContextOverride unless the ContextLoc and L
paren/brace/bracket are on different lines. Combined with the fact that we
only set them if the L and R parens/braces/brackets are on different lines
to, it guarantees there will be at most one override that's applicable on
any given line, which lets us simplify the logic somewhat.

aedafe980f [SourceKit/CodeFormat] Improve documentation and fix propagation of ContextLocs.
- Rename several symbols to make it clearer whether the ranges they deal with
  are open or closed.
- Add comments documenting the implementation of OutdentChecker::hasOutdent
- Fix a bug where code after a doc coment block of the '/**' style was being
  indented 1 space.
- Fix IsInStringLiteral not being set if the indent target was in a string
  segment of an interpolated multiline string.
- Update OutdentChecker::hasOutdent to propagate indent contexts from
  parent parens/brackets/braces to child parens/brackets/braces that start
  later in the same line (like FormatWalker already does). This changes the
  braces in the example below to 'inherit' a ContextLoc from their parent
  square brackets, which have a ContextLoc at 'foo'. This makes the whole
  expression be correctly considered 'outdenting':

  foo(a: "hello"
      b: "hello")[x: {
    print("hello")
  }]

a368434432 [SourceKit/CodeFormat] Re-work and improve the indentation implementation.
This restructures the indentation logic around producing a single IndentContext
for the line being indented. An IndentContext has:
- a ContextLoc, which points to a source location to indent relative to,
- a Kind, indicating whether we should align with that location exactly, or
  with the start of the content on its containing line, and
- an IndentLevel with the relative number of levels to indent by.

It also improves the handling of:
- chained and nested parens, braces, square brackets and angle brackets, and
  how those interact with the exact alignment of parameters, call arguments,
  and tuple, array and dictionary elements.
- Indenting to the correct level after an incomplete expression, statement or
  decl.
