Member Enumeration Documentation

enum YCPDebugger::EntryPoint

Enum of entrypoints for the function debug.

Enumerator:

Interpreter
Block

Constructor & Destructor Documentation

YCPDebugger::YCPDebugger

(

bool

)

Constructor for debugger. The parameter determines whether to block (in the first debug call) until the frontend connects or not.

YCPDebugger::~YCPDebugger

(

)

Destructor for debugger.

Member Function Documentation

void YCPDebugger::add_breakpoint ( const string &  , int    )

private

Adds a breakpoint to the list of breakpoints.

bool YCPDebugger::check_breakpoints ( const string &  , int    )

private

Checks if the given position does matches a breakpoint and returns true if so.

void YCPDebugger::check_socket ( bool  )

private

Checks if data arrived on our socket. The parameter determines whether to block until data arrives or not.

void YCPDebugger::create_socket ( )

private

Creates the socket we are listening on.

void YCPDebugger::debug	(	EntryPoint	,
		const YCPElement &
	)

Main debug function. It is called in YCode::evaluate and YBlock::evaluate.

bool YCPDebugger::delete_breakpoint ( const string &  , int    )

private

Deletes a breakpoint from the list of breakpoints. Return false if no matching breakpoint was found.

bool YCPDebugger::handle_command ( const string &  , const YCPElement &  elem  )

private

Handles a command from the frontend. The return value specifies whether the execution should continue or not.

bool YCPDebugger::ignore ( EntryPoint  , const YCPElement &    )

private

Used to ignore the calls to "_fullname", which the user does not want to debug and most important the filename is wrong during these calls.

void YCPDebugger::list_breakpoints ( )

private

Prints a list of all breakpoints.

void YCPDebugger::list_source ( const char *  )

private

Prints the current source file.

void YCPDebugger::print_scope ( )

private

Prints the entire variable scope.

bool YCPDebugger::print_variable ( const string &  )

private

Prints a single variable.

string YCPDebugger::read_line ( bool  ) const

private

Reads a line from the file descriptor. The parameter determines whether to block or not.

void YCPDebugger::write_line ( const char *  ,   ...  ) const

private

Writes a line to the file descriptor.

void void YCPDebugger::write_prompt ( ) const

private

Writes the prompt to the file descriptor.

Member Data Documentation

vector<Breakpoint> YCPDebugger::breakpoints

private

List of breakpoints.

bool YCPDebugger::close_request

private

The frontend wants to detach from the debugger.

int YCPDebugger::fd

private

The file descriptor we are communication on. Note: We only allow one debugger to be connected.

int YCPDebugger::hold_level

private

Stop execution if the level is smaller than or equal to the hold_level.

string YCPDebugger::last_command

private

The command received last.

Position YCPDebugger::leave_position

private

Stop execution if execution leaves this position.

Settings YCPDebugger::settings

private

The user settings.

bool YCPDebugger::single_mode

private

Stop execution at the next possible point.

int YCPDebugger::sock

private

The socket we are listening on.

bool YCPDebugger::wait_for_frontend

private

Block (in the first debug call) until the frontend connects.
