pybindmagic

An IPython kernel magic library. After import pybindmagic you can use the cell magic %%cpp

In this cell you can write cpp code.

Requirements

• pybind11
• git
• gcc
• cmake (optional)

Installation

pip install git+https://git.finnendahl.de/Yugon/pybindmagic.git

TODOS

• add options for cmake flags
• add other compilers
• Better exception handling
  • Better debugging output

Options

defs

You need to specify all functions or classes you want to expose to python. Either by %%cpp -f funcname or by pybind11 syntax at the end of the cell. There is a shortcut by inserting a defs in the end of the cell that will add the correct module name. For an example take a look at the example notebook.

Compiler

Currently only gcc is supported. The default compiler command is c++. You can change the compiler command with: pybindmagic.compiler_cmd = "gcc"

CMake

With %%cpp -c path/to/folder/with/CMakeList.txt/in you can specify cmake compilation. After evaluation pybind11 will be downloaded and moved to this folder, a build folder is generated and the cell is compiled in this folder. Makesure that you add pybind11 to your cmake file.

rebuild

With the %cpp -rebuild flag you can enforce a complete rebuild.
