c-kernel

IPython kernels for teaching and learning C/C++ in a Jupyter notebook, providing C/C++ syntax highlighting, automatic compilation and a little more magic.

AutoCompileKernel

Automatically compile cells into object files or executables using the name given on the cell's first line:

Specify options in comments using //%:

Compose simple multi-file projects in a single notebook:

Interactive text input between notebook and the compiled executable:

Available options

The following options can be specified in a //% magic comment within a code cell:

Option	Meaning	Example
CC	set the C compiler	CC clang
CXX	set the C++ compiler	CXX clang++
CFLAGS	add C compilation flags	CFLAGS -Wall
CXXFLAGS	add C++ compilation flags	CXXFLAGS -std=c++17
LDFLAGS	add linker flags	LDFLAGS -lm
DEPENDS	add .o dependencies, separated by spaces	DEPENDS mycode.o
VERBOSE	extra output from the kernel
ARGS	command-line arguments to the executable	ARGS arg1 arg2 etc
NOCOMPILE	save and don't compile the code cell
NOEXEC	save and compile, but don't execute the code cell

Installation

To install with pip:

python3 -m pip install ckernel

To install from git:

git clone [e-mail]:adamtuft/c-kernel.git
python3 -m pip install ./c-kernel

Then, install the kernel(s), giving it a name and a display name of your choice. For example, to install AutoCompileKernel using clang and clang++ as the default compilers, run:

ckernel install AutoCompileKernel autocompile-clang "Auto-compile C/C++ (clang)" --user --cc clang --cxx clang++

This kernel will then be available under the name "Auto-compile C/C++ (clang)" in Jupyter:

Here are some commands for installing the kernel for use with clang and gcc, with both regular and debug versions:

python3 -m ckernel install AutoCompileKernel autocompile-gcc "Auto-compile C/C++ (gcc)" --user --cc gcc --cxx g++
python3 -m ckernel install AutoCompileKernel autocompile-gcc-debug "Auto-compile C/C++ (gcc) (debug)" --user --debug --cc gcc --cxx g++
python3 -m ckernel install AutoCompileKernel autocompile-clang "Auto-compile C/C++ (clang)" --user --cc clang --cxx clang++
python3 -m ckernel install AutoCompileKernel autocompile-clang-debug "Auto-compile C/C++ (clang) (debug)" --user --debug --cc clang --cxx clang++

See ckernel install --help for all options.
