Document Links

Clickable links from source directives to their resolved target files.

Known limitation: link targets are currently emitted as raw filesystem paths instead of file:/// URIs. Clients that strictly validate DocumentUri may not navigate these links.

Include Directives

• #include "..." — link to resolved header file

• #include <...> — link to resolved system header

• __has_include(...) — link to checked file

• #embed "..." — link to embedded resource file

• __has_embed(...) — link to checked embed file

• #include_next — link to the resolved next-in-search-path header

• Macro-expanded include paths — resolve and link when the path is produced by a macro (clangd#2375)

  #define HEADER "config.h"
  #include HEADER  // should link to config.h

• __has_include_next(...) — link to checked file

• Show resolved absolute path as tooltip

  #include <vector>
  // tooltip: /usr/include/c++/14/vector

Module Declarations

• import module_name; — link to module interface file
• import :partition; — link to partition file
• module module_name; — link to module interface (from implementation unit)
• export import module_name; — link to re-exported module interface
