Class lib_settings_class (o2scl)

O2scl : Class List

class lib_settings_class

A class to manage global library settings.

This class reports global settings such as the current version, whether or not sub-libraries were installed and what the current parent directory for data files is.

A global object of this type is defined in lib_settings.h named o2scl_settings .

This class should not typically be instantiated by the end-user.

Unit conversion objects

convert_units<double> def_cu

Default convert_units object.

unsigned int seed

Seed for thread-safe random number generation rng_set_seed()

bool py_initialized

True if Python has been initialized (default false)

inline convert_units<double> &get_convert_units()

Get the global convert_units object.

int py_init_nothrow(int verbose = 0)

Initialize the python interface.

This function uses the environment variable O2SCL_PYTHON_EXT to set the Python name via the function Py_SetProgramName() before the function Py_Initialize() is called.

void py_init(int verbose = 0)

Initialize the python interface.

This function uses the environment variable O2SCL_PYTHON_EXT to set the Python name via the function Py_SetProgramName() before the function Py_Initialize() is called.

int py_final_nothrow(int verbose = 0)

Finalize the python interface.

void py_final(int verbose = 0)

Finalize the python interface.

std::string py_version()

String containing python version.

void *py_import_array()

Import arrays for numpy C api.

std::string py_get_module_path(std::string module)

Get the path for the Python module named module.

void add_python_path(std::string path, int verbose = 0)

Add path path to the python system search path.

void get_python_path(std::vector<std::string> &vs, int verbose = 0)

Get the python path and place the path strings in vs.

PyObject *py_import_module(std::string module, int verbose = 0)

Import module named module.

This function outputs some debugging information if the module import fails. The function py_init() must be called first.

Internal data set in the constructor [protected]

std::string data_dir

The present data directory.

std::string doc_dir

The present documentation directory.

convert_units<double> *cup

Pointer to current convert_units object.

find_constants *fcp

Pointer to current find_constants object.
