Ipython cell magic to run and time C++ code

CppMagic

Ipython cell magic for jupyter notebooks to run and time C++ code.

Usage

Load extension using %load_ext cppmagic.
Use %%cpp at the beginning of the cell and write your C++ code. Execute to get results or compilation errors.
Use %%cpp -t to get a timeit result.

Installation

pip install git+git://github.com/xapharius/cppmagic.git

Examples

example.ipynb

%load_ext cppmagic

• Example 1: Get stdout

%%cpp

#include <stdio.h>

int main(void) {
   printf("Hello World");
   return 0;
}

'Hello World'

• Example 2: Time execution (compilation time is excluded)

%%cpp -t

#include <stdio.h>

int main(void) {
   printf("Hello World");
   return 0;
}

<TimeitResult : 3.45 ms ± 354 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)>

• Example 3: Get compilation errors

%%cpp

#include <stdio.h>

int main(void) {
   printf("Hello World")
   return 0;
}

TODO:

• test on windows
• test on python 2
• add compiler flags
• add timeit params
