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")
}
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.
- 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")
}]
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.

Previously closing square brackets would be caught in the logic for
elements in collections, indenting them to the same level. Now they are
indented with the normal non-sibling logic, which indents them
correctly.
[SourceKit] Indentation: when the indented line starts with open brace and the
line before starts with a leading declaration keywords, we never add
indentation level on the brace. rdar://28049927
* [Parser] Preserve empty getter functions to make sure indentation inside its body still works. rdar://28049927
* Using the consistent identifier even though they are identical.
What I've implemented here deviates from the current proposal text
in the following ways:
- I had to introduce a FunctionArrowPrecedence to capture the parsing
of -> in expression contexts.
- I found it convenient to continue to model the assignment property
explicitly.
- The comparison and casting operators have historically been
non-associative; I have chosen to preserve that, since I don't
think this proposal intended to change it.
- This uses the precedence group names and higherThan/lowerThan
as agreed in discussion.
and provide a fix-it to move it to the new location as referenced
in SE-0081.
Fix up a few stray places in the standard library that is still using
the old syntax.
Update any ./test files that aren't expecting the new warning/fix-it
in -verify mode.
While investigating what I thought was a new crash due to this new
diagnostic, I discovered two sources of quite a few compiler crashers
related to unterminated generic parameter lists, where the right
angle bracket source location was getting unconditionally set to
the current token, even though it wasn't actually a '>'.
This ends up creating too much indentation in some common cases.
This effectively get us back to indentation behavior of Swift 2.2.

This makes it more clear what the response string contains, plus you can copy the
printed request directly for passing to sourcekitd_request_create_from_yaml.
Parameters (to methods, initializers, accessors, subscripts, etc) have always been represented
as Pattern's (of a particular sort), stemming from an early design direction that was abandoned.
Being built on top of patterns leads to patterns being overly complicated (e.g. tuple patterns
have to have varargs and default parameters) and make working on parameter lists complicated
and error prone. This might have been ok in 2015, but there is no way we can live like this in
2016.
Instead of using Patterns, carve out a new ParameterList and Parameter type to represent all the
parameter specific stuff. This simplifies many things and allows a lot of simplifications.
Unfortunately, I wasn't able to do this very incrementally, so this is a huge patch. The good
news is that it erases a ton of code, and the technical debt that went with it. Ignoring test
suite changes, we have:
77 files changed, 2359 insertions(+), 3221 deletions(-)
This patch also makes a bunch of wierd things dead, but I'll sweep those out in follow-on
patches.
Fixes <rdar://problem/22846558> No code completions in Foo( when Foo has error type
Fixes <rdar://problem/24026538> Slight regression in generated header, which I filed to go with 3a23d75.
Fixes an overloading bug involving default arguments and curried functions (see the diff to
Constraints/diagnostics.swift, which we now correctly accept).
Fixes cases where problems with parameters would get emitted multiple times, e.g. in the
test/Parse/subscripting.swift testcase.
The source range for ParamDecl now includes its type, which permutes some of the IDE / SourceModel tests
(for the better, I think).
Eliminates the bogus "type annotation missing in pattern" error message when a type isn't
specified for a parameter (see test/decl/func/functions.swift).
This now consistently parenthesizes argument lists in function types, which leads to many diffs in the
SILGen tests among others.
This does break the "sibling indentation" test in SourceKit/CodeFormat/indent-sibling.swift, and
I haven't been able to figure it out. Given that this is experimental functionality anyway,
I'm just XFAILing the test for now. i'll look at it separately from this mongo diff.
