If there is a type context, hide literal suggesetions that don't match
it, unless they are keywords and we have filtered to their names.
Incidentally fix an output buffering issue when combining filtering with
the -raw flag in complete-test.

In practice things that are float literal convertible are also integer
literal convertible so this isn't pulling its weight.

When we're code completing a postfix or dot expression inside the
subexpression of an #selector expression, prefer compound function
names. This helps us write, e.g.,
#selector(UIView.
and get completions such as "insertSubview(_:aboveSubview:)". Fixes
rdar://problem/24470075.
For a concrete type, members from its conforming protocols' extensions can be hard
to manually surface. In this commit, when printing Swift modules, we start to replicate these
extensions and synthesize them as if they are the concrete type's native extensions.
Credit to Doug for suggesting this practice.
When one spells a compound declaration name in the source (e.g.,
insertSubview(_:aboveSubview:), keep track of the locations of the
base name, parentheses, and argument labels.
Basic implementatation of SE-0021, naming functions with argument
labels. Handle parsing of compound function names in various
unqualified-identifier productions, updating the AST representation of
various expressions from Identifiers to DeclNames. The result doesn't
capture all of the source locations we want; more on that later.
As part of this, remove the parsing code for the "selector-style"
method names, since we now have a replacement. The feature was never
publicized and doesn't make sense in Swift, so zap it outright.
Adds an associatedtype keyword to the parser tokens, and accepts either
typealias or associatedtype to create an AssociatedTypeDecl, warning
that the former is deprecated. The ASTPrinter now emits associatedtype
for AssociatedTypeDecls.
Separated AssociatedType from TypeAlias as two different kinds of
CodeCompletionDeclKinds. This part probably doesn’t turn out to be
absolutely necessary currently, but it is nice cleanup from formerly
specifically glomming the two together.
And then many, many changes to tests. The actual new tests for the fixits
is at the end of Generics/associated_types.swift.
This utility helps us reconstruct type from a mangled name. SourceKit needs this functionality to deliver
richer doc-info/cursor-info.
Thanks for Sean's help!
A decl’s full GenericSignature is set during validateGenericTypeSignature().
Then during ConstraintSystem::openTypes(), in ReplaceDependentTypes, the GenericArgs list is built from the generic signature (via getGenericParamTypes()) and passed into a new BoundGenericType.
In BoundGenericType::getSubstitutions(), the GenericArgs are assumed to match getGenericParamsOfContext()->getParams().
However, in reality, the GenericArgs include all levels of generic args, whereas getGenericParamsOfContext() are the params of the innermost context only, so the params array is accessed past its end.
This commit changes NominalTypeDecl::getGenericParamTypes() to return the innermost params, in order to match the output of BoundGenericType::getGenericArgs(). For clarity and to hopefully prevent future confusion, we also rename getGenericParamTypes() to getInnermostGenericParamTypes().
Under -enable-infer-default-arguments, the Clang importer infers some
default arguments for imported declarations. Rather than jumping
through awful hoops to make sure that we create default argument
generators (which will likely imply eager type checking), simply
handle these cases as callee-side expansions.
This makes -enable-infer-default-arguments usable, fixing
rdar://problem/24049927.
