The enhanced SourceKitd requests are EditorOpen and EdtiorReplaceText. In these two requests, the clients can specify a flag "key. enablesyntaxtree = 1" to get a serialize libSyntax tree with the response.
To help this integration, we added a function in SyntaxParsingContext to explicitly finalize the creation of a SourceFileSyntax to incorporate the fact that SourceKit needs the tree before its destroying the parser instance.
To test this integration, we diff the syntax tree serialized from the frontend action and the tree serialized from a SourceKitd response. They should be identical.
This has three principal advantages:
- It gives some additional type-safety when working
with known accessors.
- It makes it significantly easier to test whether a declaration
is an accessor and encourages the use of a common idiom.
- It saves a small amount of memory in both FuncDecl and its
serialized form.
After my PR 13591 to adjust for LLVM r321257, the Linux bots are failing with
errors about missing conversions. For some reason that I don't understand,
those errors do not reproduce when I build locally on macOS. I think this
change should fix them. I also cleaned up some const_casts that should now
be unnecessary when using WritableMemoryBuffer.
Explicitly instantiate the `CursorInfoData` instances when using it with
the default constructor rather than using the inline initializer list.
This is needed to build with C++14 mode. Provide a default value for
the `Optional` type in the structure which prevents a non-copy default
constructor from being synthesized. NFC.
When completing
Foo(<here>
We will now provide
bar: <#value#>
instead of
bar: <#value#>)
Inserting the rparen caused some problems in practice:
* the old behaviour optimized for typing Foo(<complete> instead of
Foo(<complete>), which can conflict with user behaviours or ...
* in editors with automatic brace-matching, we often conflicted with the
editor, leading to extraneous closing parens
And in general, it is much more predictable for tooling to either insert
matching ( and ) or to not insert either. While this change may not be
ideal For users of editors that do not do automatic brace-matching, I
believe it is still better overall to have to type a missing paren than
to have to delete an extraneous one.

The original hope was we could make these heuristics really good, but
since that is not currently in sight (and may never be), we want to be
able to turn them off. For now, just plumb through an internal flag to
control the behaviour. A future change will customize the behaviour in
SourceKit.

- Outlaw duplicate input files, fix driver, fix tests, and add test.
- Reflect that no buffer is present without a (possibly pseudo) named file.
- Reflect fact that every input has a (possible pseudo) name.
- Break up CompilerInstance::setup.

Rename isPrimaryInputAFileAt to isThereAPrimaryInputWithAFilenameAt.
Added a FIXME in doesActionProduceOutput to reflect that some actions actually do not produce output.
Adds support for renaming subscripts with external names, e.g.
subscript(x y: Int), and introduces a noncollapsible parameter name range for
subscript parameters, since these shouldn't be collapsed with an argument label
of the same name as function parameter names are.
When expanding placeholders, we analyze the surrounding context of a
placeholder to decide whether to expand the placeholder to a trailing
closure. This analysis assumes CallExpr is the only AST node with argument;
however UnresolvedMemberExpr can have argument as well. This commit
teaches the analysis logic to handle both.
