sos-xeus-cling

SoS extension for C++. Developed independently from original SoS team. Please refer to SoS Homepage for details.

This language extension to SoS allows to use C++ with xeus-cling Jupyter kernel (https://github.com/QuantStack/xeus-cling) and exchange variables with other languages in Polyglot environment

Dependencies

  • gcc apt-get update; apt-get install gcc
  • xeus-cling conda install xeus-cling xwidgets notebook xtensor xtl xframe -c conda-forge/label/gcc7
  • sos-notebook pip install sos-notebook --upgrade; python -m sos_notebook.install

Install

pip install sos-xeus-cling

Supported variable types for transfer

From SoS to C++ (%get magic):

Scalar types

Source: SoS (Python) type Destination: C++ type
int long int np.intc np.intp np.int8 np.int16 np.int32 np.int64 int long int (depending on value)
float np.float16 np.float32 np.float64 float double (depending on value)
np.longdouble long double
str std::string
bool bool

Non-scalar types

Source: SoS (Python) type Destination: C++ type
dict (only homogeneous keys and values) std::map<key_type, val_type>
Sequence (list, tuple; only homogeneous elements) std::vector<type>
numpy.ndarray Xtensor xt::xarray
pandas.DataFrame Xframe
