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;
}
