- Added missing ifdef guard in PointerIntEnum header
- Consistent naming convention for ifdef guards
- Consistent 'end namespace swift'
- Consistent single EOL at end of header files
Introduces import-as-member (IAM) inferene system, to automatically
infer details that would otherwise have to be manually specified with
the swift_name attribute.
Basic functionality present, though there are some issues with
properties at the moment. No hooks, options, or tests yet, stay tuned.
Allow all keywords except for parameter introducers (var/let/inout) to
be argument labels when declaring or calling a
function/initializer/subscript, e.g., this
func touchesMatching(phase: NSTouchPhase, `in` view: NSView?) -> Set<NSTouch>
can now be expressed as
func touchesMatching(phase: NSTouchPhase, in view: NSView?) -> Set<NSTouch>
and the call goes from
event.touchesMatching(phase, `in`: view)
to
event.touchesMatching(phase, in: view)
Fixes [SR-344](https://bugs.swift.org/browse/SR-344) /
rdar://problem/22415674.
The properties of a context indicate those things that are considered
"contained within" the context (among other things). This helps us
avoid producing overly-generic names when we identify a redundancy in
the base name. For example, NSView contains the following:
var gestureRecognizers: [NSGestureRecognizer]
func addGestureRecognizer(gestureRecognizer: NSGestureRecognizer)
func removeGestureRecognizer(gestureRecognizer: NSGestureRecognizer)
Normally, omit-needless-words would prune the two method names down to
"add" and "remove", respectively, because they restate type
information. However, this pruning is not ideal, because a view isn't
primarily a collection of gesture recognizers.
Use the presence of the property "gestureRecognizers" to indicate that
we should not strip "gestureRecognizer" or "gestureRecognizers" from
the base names of methods within that class (or its subclasses).
Note that there is more work to do here to properly deal with API
evolution: a newly-added property shouldn't have any effect on
existing APIs. We should use availability information here, and only
consider properties introduced no later than the entity under
consideration.
Prepend "is" to Boolean property names (e.g., "empty" becomes
"isEmpty") unless the property name strongly indicates its Boolean
nature or we're likely to ruin the name. Therefore, the presence of
one of the following in the property name will suppress this
transformation:
* An auxiliary verb, such as "is", "has", "may", "should", or "will".
* A word ending in "s", indicating either a plural (for which
prepending "is" would be incorrect) or a verb in the continuous
tense (which indicates its Boolean nature, e.g., "translates" in
"translatesCoordinates").

When the first parameter of a function has Boolean type, try to create
an argument label for it. We start with the (normally non-API)
parameter name as the argument label, then try to match that against
the end of the base name of the method to eliminate redundancy. Add a
little magic, and here are some diffs:
- func openUntitledDocumentAndDisplay(_: Bool) throws -> NSDocument
+ func openUntitledDocument(display _: Bool) throws -> NSDocument
- func fontMenu(_: Bool) -> NSMenu?
- func fontPanel(_: Bool) -> NSFontPanel?
+ func fontMenu(create _: Bool) -> NSMenu?
+ func fontPanel(create _: Bool) -> NSFontPanel?
- func lockFocusFlipped(_: Bool)
+ func lockFocus(flipped _: Bool)
- func rectForSearchTextWhenCentered(_: Bool) -> NSRect
+ func rectForSearchText(whenCentered _: Bool) -> NSRect
- func dismissPreviewAnimated(_: Bool)
- func dismissMenuAnimated(_: Bool)
+ func dismissPreview(animated _: Bool)
+ func dismissMenu(animated _: Bool)

When the context type of a declaraton matches the result type,
strip off redundant type information at the beginning of the
declaration name if it is followed by a preposition. This covers the
class of transformations on performs on a class that produce a value
of the same type as that class, e.g., NSURL's "URLWithHTTPS" or
NSString's "stringByAppendingString".
When that preposition is the magical "By" and is followed by a gerund,
strip the "By" as well. Note that this is slightly more conservative
now for methods, which previously stripped based on the result type
(always). For example, in NSCalendar:
- func adding(_: NSDateComponents, to: NSDate, options:
NSCalendarOptions = [])
-> NSDate?
+ func dateByAdding(_: NSDateComponents, to: NSDate, options:
NSCalendarOptions
= []) -> NSDate?
but it's more general for properties, e.g.,
- @NSCopying var bezierPathByFlattening: NSBezierPath { get }
- @NSCopying var bezierPathByReversing: NSBezierPath { get }
+ @NSCopying var byFlattening: NSBezierPath { get }
+ @NSCopying var reversing: NSBezierPath { get }
The important part is that the rules are more uniform and the code is
more regularly structured: we strip this leading type information when
it's redundant with the context and result type, regardless of whether
we have a property or a method, and the "By" rule is no longer special
in that regard.
Swift SVN r32129
Split the base name at the last preposition, but *only* when the first
parameter is defaulted, because defaulted arguments might not show up
at the call site and the longer base name can feel odd in such
cases. With this, stop avoiding the argument label "with": it's fine
when we have actual context at the call site, and the "with: nil" case
no longer happens now that we're defaulting nil.
Swift SVN r32098
When the prefix of a method/property name is restating the result
type, followed by "By" and then a gerund, drop everything up to the
gerund. For example:
func stringByAppendingString(string: String) -> String
becomes
func appending(string: String) -> String
Swift SVN r31683
When the type name we're looking at is a collection of some element
type, also try to match the plural form of the element type name. For
example:
- func deselectItemsAtIndexPaths(_: Set<NSIndexPath>)
+ func deselectItemsAt(_: Set<NSIndexPath>)
Swift SVN r31666
Identify gerunds by stripping off the "ing" and looking for a
verb. This lets us transform, e.g., "stringByAppendingString" to
"stringByAppending", since "append" is a verb.
Swift SVN r31660
The presence of a verb or preposition prior to the redundant part
provides a firm linguistic split that lets the actual argument fill in
for the reader. For other parts of speech (adjectives, especially)
it's awkward to transition from "reading part of the name" to "reading
the argument". This eliminates a significant number of bad omissions,
e.g., "setTextColor()" -> "setText()", and generally makes the
transformation more conservative.
Swift SVN r31656
Sink the actual logic for omitting needless words way down into
Basic, so we can re-use it elsewhere. Tie the Clang importer into that
logic, mapping Clang types down to strings appropriately. NFC

When importing an Objective-C init method or factory method into an
initializer, if the first camelCase word of the first argument name
starts with "with", drop the "with". This means that
-initWithRed:green:blue:alpha:
will get imported into Swift as
init(red:green:blue:alpha:)
as will
+colorWithRed:green:blue:alpha:
This is <rdar://problem/16795899>, hidden behind the
-implicit-objc-with flag.

This makes a number of changes to the selector-splitting
heuristics. Specifically:
- Eliminate last-word splitting, and with it the notion of
multi-words. We only split at prepositions now.
- Introduce the notion of "linking verbs" such as "will" or
"should"; when these show up, we refuse to split a selector, which
helps with delegates.
- Eliminate the special case for "get" and "set". It wasn't
helping.
