Typedef Documentation

Callback

template<typename T >

using clang::clangd::Callback = typedef llvm::unique_function<void(llvm::Expected<T>)>

A Callback<T> is a void function that accepts Expected<T>.

This is accepted by ClangdServer functions that logically return T.

Definition at line 28 of file Function.h.

Canceler

using clang::clangd::Canceler = typedef std::function<void()>

A canceller requests cancellation of a task, when called.

Calling it again has no effect.

Definition at line 70 of file Cancellation.h.

CharTypeSet

using clang::clangd::CharTypeSet = typedef unsigned char

Definition at line 49 of file FuzzyMatch.h.

CompletionItemKindBitset

using clang::clangd::CompletionItemKindBitset = typedef std::bitset<CompletionItemKindMax + 1>

Definition at line 325 of file Protocol.h.

FileDigest

using clang::clangd::FileDigest = typedef std::array<uint8_t, 8>

Definition at line 41 of file SourceCode.h.

FileEdits

using clang::clangd::FileEdits = typedef llvm::StringMap<Edit>

A mapping from absolute file path (the one used for accessing the underlying VFS) to edits.

Definition at line 204 of file SourceCode.h.

IncludeGraph

using clang::clangd::IncludeGraph = typedef llvm::StringMap<IncludeGraphNode>

Definition at line 92 of file Headers.h.

IndexFactory

using clang::clangd::IndexFactory = typedef std::function<std::unique_ptr<SymbolIndex>( const Config::ExternalIndexSpec &, AsyncTaskRunner *)>

A functor to create an index for an external index specification.

using clang::clangd::InitializedParams = typedef NoParams

Definition at line 274 of file Protocol.h.

Obj

using clang::clangd::Obj = typedef llvm::json::Object

TemplateInstantiation	This is the template instantiation that was referred to. e.g. template<> class vector<int> (the implicit specialization)
TemplatePattern	This is the pattern the template specialization was instantiated from. e.g. class vector<T> (the pattern within the primary template)
Alias	This declaration is an alias that was referred to. e.g. using ns::X (the UsingDecl directly referenced), using Z = ns::Y (the TypeAliasDecl directly referenced)
Underlying	This is the underlying declaration for a renaming-alias, decltype etc. e.g. class ns::Y (the underlying declaration referenced). Note that we don't treat using ns::X as a first-class declaration like using Z = ns::Y. Therefore reference to X that goes through this using-decl is considered a direct reference (without the Underlying bit). Nevertheless, we report using ns::X as an Alias, so that some features like go-to-definition can still target it.

Returns a CommentHandler that parses pragma comment on include files to determine when we should include a different header from the header that directly defines a symbol.

Currently it only supports IWYU private pragma: https://github.com/include-what-you-use/include-what-you-use/blob/master/docs/IWYUPragmas.md#iwyu-pragma-private

We ignore other pragmas:

• keep: this is common but irrelevant: we do not currently remove includes
• export: this is common and potentially interesting, there are three cases:
  • Points to a public header (common): we can suppress include2 if you already have include1. Only marginally useful.
  • Points to a private header annotated with private (somewhat commmon): Not incrementally useful as we support private.
  • Points to a private header without pragmas (rare). This is a reversed private pragma, and is valuable but too rare to be worthwhile.
• no_include: this is about as common as private, but only affects the current file, so the value is smaller. We could add support.
• friend: this is less common than private, has implementation difficulties, and affects behavior in a limited scope.
• associated: extremely rare

findReferencedLocations()

ReferencedLocations clang::clangd::findReferencedLocations

(

ParsedAST &

AST

)

Finds locations of all symbols used in the main file.

• RecursiveASTVisitor finds references to symbols and records their associated locations. These may be macro expansions, and are not resolved to their spelling or expansion location. These locations are later used to determine which headers should be marked as "used" and "directly used".
• We also examine all identifier tokens in the file in case they reference macros.

We use this to compute unused headers, so we:

• cover the whole file in a single traversal for efficiency
• don't attempt to describe where symbols were referenced from in ambiguous cases (e.g. implicitly used symbols, multiple declarations)
• err on the side of reporting all possible locations

formatIncremental()

std::vector< tooling::Replacement > clang::clangd::formatIncremental	(	llvm::StringRef	Code,

Applies limited formatting around new InsertedText.

The Code already contains the updated text before Cursor, and may have had additional / characters (such as indentation) inserted by the editor.

Example breaking a line (^ is the cursor): === before newline is typed === if(1){^} === after newline is typed and editor indents === if(1){ ^} === after formatIncremental(InsertedText="\n") === if (1) { ^ }

We return sorted vector<tooling::Replacement>, not tooling::Replacements! We may insert text both before and after the cursor. tooling::Replacements would merge these, and thus lose information about cursor position.

std::string clang::clangd::getQualification	(	ASTContext &	Context,
		const DeclContext *	DestContext,
		const NamedDecl *	ND,

	)

This function uses the VisibleNamespaces to figure out if a shorter qualification is sufficient for ND, and ignores any using namespace directives.

It can be useful if there's no AST for the DestContext, but some pseudo-parsing is done. i.e. if ND is ns1::ns2::X and DestContext is ns1::, users can provide ns2:: as visible to change the result to be empty. Elements in VisibleNamespaces should be in the form: ns::, with trailing "::". Note that this is just textual and might be incorrect. e.g. when there are two namespaces ns1::a and ns2::a, the function will early exit if "a::" is present in VisibleNamespaces, no matter whether it is from ns1:: or ns2::

Definition at line 529 of file AST.cpp.

getQualification() [2/2]

std::string clang::clangd::getQualification	(	ASTContext &	Context,
		const DeclContext *	DestContext,
		SourceLocation	InsertionPoint,
		const NamedDecl *	ND
	)

Gets the nested name specifier necessary for spelling ND in DestContext, at InsertionPoint.

It selects the shortest suffix of ND such that it is visible in DestContext. Returns an empty string if no qualification is necessary. For example, if you want to qualify clang::clangd::bar::foo in clang::clangd::x, this function will return bar. Note that the result might be sub-optimal for classes, e.g. when the ND is a member of the base class.

This version considers all the using namespace directives before InsertionPoint. i.e, if you have using namespace clang::clangd::bar, this function will return an empty string for the example above since no qualification is necessary in that case. FIXME: Also take using directives and namespace aliases inside function body into account.

Searches for the symbols matching Query.

The syntax of Query can be the non-qualified name or fully qualified of a symbol. For example, "vector" will match the symbol std::vector and "std::vector" would also match it. Direct children of scopes (namespaces, etc) can be listed with a trailing "::". For example, "std::" will list all children of the std namespace and "::" alone will list all children of the global namespace. Limit limits the number of results returned (0 means no limit).

hasUnstableLinkage()

bool clang::clangd::hasUnstableLinkage

(

const Decl *

D

)

Whether we must avoid computing linkage for D during code completion.

Clang aggressively caches linkage computation, which is stable after the AST is built. Unfortunately the AST is incomplete during code completion, so linkage may still change.

Example: auto x = []{^} at file scope. During code completion, the initializer for x hasn't been parsed yet. x has type undeduced auto, and external linkage. If we compute linkage at this point, the external linkage will be cached.

After code completion the initializer is attached, and x has a lambda type. This means x has "unique external" linkage. If we computed linkage above, the cached value is incorrect. (clang catches this with an assertion).
