Member Typedef Documentation

Ptr

using Rosebud::Ast::CppStack::Ptr = CppStackPtr

Shared-ownership pointer.

Definition at line 135 of file Ast.h.

Level

using Rosebud::Ast::CppStack::Level = std::list<Directive>

The CPP directives that belong to the same level.

E.g., a matching #if, #elif, and #else. The first element of the pair indicates the type of directive in the first element of the list. The list is never empty.

Definition at line 156 of file Ast.h.

Stack

using Rosebud::Ast::CppStack::Stack = std::vector<Level>

A stack of nested conditional compilation directives.

The earlier entries enclose the later entries.

Definition at line 161 of file Ast.h.

Member Enumeration Documentation

Type

enum class Rosebud::Ast::CppStack::Type

strong

Type of CPP directive.

Enumerator
IF	#if, #ifdef, or #ifndef.
ELSE	#else or #elif
END	#endif
OTHER	Not a conditional compilation directive.

Definition at line 138 of file Ast.h.

Member Function Documentation

process()

static bool Rosebud::Ast::CppStack::process ( const FilePtr &  , const Token &  directive, Stack &  runningStack  )

static

Adjust the stack based on the C preprocessor directive.

Returns true if the stack was adjusted, false otherwise.

printError()

bool Rosebud::Ast::CppStack::printError

(

const FilePtr &

file

)

const

Print an error message for the top of the stack if there's something wrong with it.

Returns true if an error was printed.
