buffered_istream preprocessor_data::in_

private

Input stream.

Definition at line 491 of file preprocessor.cpp.

filesystem::scoped_istream preprocessor_data::in_scope_

private

Manages the lifetime of the std::istream pointer we own.

Since in_ uses the stream as well this object must be created before in_ and destroyed after in_ is destroyed.

Definition at line 488 of file preprocessor.cpp.

bool preprocessor_data::is_define_

private

true iff we are currently parsing a macros content, otherwise false.

Definition at line 514 of file preprocessor.cpp.

std::map<std::string, std::string>* preprocessor_data::local_defines_

private

Mapping of macro arguments to their content.

Definition at line 497 of file preprocessor.cpp.

Referenced by get_chunk(), and ~preprocessor_data().

int preprocessor_data::skipping_

private

Non-zero when the preprocessor has to skip some input text.

Increased whenever entering a conditional branch that is not useful, e.g. a ifdef that evaluates to false.

Definition at line 511 of file preprocessor.cpp.

Referenced by conditional_skip(), get_chunk(), push_token(), and put().

int preprocessor_data::slowpath_

private

Set to true whenever input tokens cannot be directly sent to the target buffer.

For instance, this happens with macro arguments. In that case, the output is redirected toward strings_ until it can be processed.

std::vector< token_desc > preprocessor_data::tokens_

private
