Member Function Documentation

◆ insert()

std::optional< tooling::Replacement > clang::tooling::HeaderIncludes::insert	(	llvm::StringRef	Header,
		bool	IsAngled,
		IncludeDirective	Directive
	)		const

Inserts an #include or #import directive of Header into the code.

If IsAngled is true, Header will be quoted with <> in the directive; otherwise, it will be quoted with "".

When searching for points to insert new header, this ignores #include's after the #include block(s) in the beginning of a file to avoid inserting headers into code sections where new #include's should not be added by default. These code sections include:

raw string literals (containing #include).
if blocks.
Special #include's among declarations (e.g. functions).

Returns a replacement that inserts the new header into a suitable #include block of the same category. This respects the order of the existing #includes in the block; if the existing #includes are not already sorted, this will simply insert the #include in front of the first #include of the same category in the code that should be sorted after IncludeName. If IncludeName already exists (with exactly the same spelling), this returns std::nullopt.

◆ remove()

tooling::Replacements clang::tooling::HeaderIncludes::remove	(	llvm::StringRef	Header,
		bool	IsAngled
	)		const

Removes all existing #includes and #imports of Header quoted with <> if IsAngled is true or "" if IsAngled is false.

This doesn't resolve the header file path; it only deletes #includes and #imports with exactly the same spelling.
