This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:
https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716
`OS << ND->getDeclName();` is equivalent to `OS << ND->getNameAsString();`
without the extra temporary string.
This is not quite a NFC since two uses of `getNameAsString` in a
diagnostic are replaced, which results in the named entity being
quoted with additional "'"s (ie: 'var' instead of var).
DynTypedNode and ASTNodeKind are implemented as part of the clang AST
library, which uses the main clang namespace. There doesn't seem to be a
need for this extra level of namespacing.
I left behind aliases in the ast_type_traits namespace for out of tree
clients of these APIs. To provide aliases for the enumerators, I used
this pattern:
namespace ast_type_traits {
constexpr TraversalKind TK_AsIs = ::clang::TK_AsIs;
}
I think the typedefs will be useful for migration, but we might be able
to drop these enumerator aliases.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Looks like these were in place to make these types move-only. That's
generally not a feature that the type should prescribe (unless it's an
inherent limitation) - instead leaving it up to the users of a type.

This commit adds an initial, skeleton outline of the "extract function"
refactoring. The extracted function doesn't capture variables / rewrite code
yet, it just basically does a simple copy-paste.
The following initiation rules are specified:
- extraction can only be done for executable code in a function/method/block.
This means that you can't extract a global variable initialize into a function
right now.
- simple literals and references are not extractable.
This commit also adds support for full source ranges to clang-refactor's test
mode.

consecutive statements
This commit adds a CodeRangeASTSelection value to the refactoring library. This
value represents a set of selected statements in one body of code.

form of PseudoObjectExpr
The new commit adjusts unittest test code compilation options so that the
Objective-C code in the unittest can be parsed on non-macOS platforms.
Original message:
The AST selection finder now constructs a selection tree that contains only the
syntactic form of PseudoObjectExpr. This form of selection tree is more
meaningful when doing downstream analysis as we're interested in the syntactic
features of the AST and the correct lexical parent relation.

This commit adds the base AST source selection component to the refactoring
library. AST selection is represented using a tree of SelectedASTNode values.
Each selected node gets its own selection kind, which can actually be None even
in the middle of tree (e.g. statement in a macro whose child is in a macro
argument). The initial version constructs a "raw" selection tree, without
applying filters and canonicalisation operations to the nodes.
