Detailed Description

Produces fixes to insert specified includes to source files, if not yet present.

IncludeInserter can be used in clang-tidy checks in the following way:

#include "../ClangTidyCheck.h"
#include "../utils/IncludeInserter.h"
 
namespace clang {
namespace tidy {
 
class MyCheck : public ClangTidyCheck {
 public:
  void registerPPCallbacks(const SourceManager &SM, Preprocessor *PP,
                           Preprocessor *ModuleExpanderPP) override {
    Inserter.registerPreprocessor(PP);
  }
 
  void registerMatchers(ast_matchers::MatchFinder* Finder) override { ... }
 
  void check(
      const ast_matchers::MatchFinder::MatchResult& Result) override {
    ...
    Inserter.createMainFileIncludeInsertion("path/to/Header.h");
    ...
  }
 
 private:
  utils::IncludeInserter Inserter{utils::IncludeSorter::IS_Google};
};
} // namespace tidy
} // namespace clang

IncludeInserter()

clang::tidy::utils::IncludeInserter::IncludeInserter ( IncludeSorter::IncludeStyle  Style )

Member Function Documentation

createIncludeInsertion()

llvm::Optional< FixItHint > clang::tidy::utils::IncludeInserter::createIncludeInsertion	(	FileID	FileID,
		llvm::StringRef	Header
	)

Creates a Header inclusion directive fixit in the File FileID.

When Header is enclosed in angle brackets, uses angle brackets in the inclusion directive, otherwise uses quotes. Returns llvm::None on error or if the inclusion directive already exists.

Definition at line 70 of file IncludeInserter.cpp.

Header

)

Creates a Header inclusion directive fixit in the main file.
