Python bindings for Elektra.

If you have the Python bindings already installed, you get started by reading the tutorial.

Installation

See installation. The package is called python3-elektra.

CMake Variables

To build the Python bindings on Debian Stretch or Buster you need:

-DPython_ADDITIONAL_VERSIONS=`py3versions -d -v`
-DSWIG_EXECUTABLE=/usr/bin/swig3.0 \
-DPYTHON_EXECUTABLE:PATH=/usr/bin/python3 \

For Python3 on Debian Jessie you need:

-DPYTHON_EXECUTABLE:PATH=/usr/bin/python3.4
-DPYTHON_LIBRARY:FILEPATH=/usr/lib/python3.4/config-3.4m-x86_64-linux-gnu/libpython3.4.so
-DPYTHON_INCLUDE_DIR:PATH=/usr/include/python3.4

On most distributions CMAKE_INSTALL_PREFIX needs to be set to /usr so that Python finds the modules without setting PYTHONPATH.

The default CMAKE_INSTALL_PREFIX (/usr/local) usually is not part of Python's default search path, see python3 -c 'import sys; print(sys.path)'. So either make sure to:

1. compile with CMAKE_INSTALL_PREFIX=/usr
2. tell CMake your correct Python site package with e.g. PYTHON_SITE_PACKAGES=/usr/lib64/python3.y/site-packages
3. extend Python's default search path at runtime with e.g. PYTHONPATH=/usr/local/lib/python3/dist-packages

Development

Note that cmake does not automatically rebuild SWIG bindings when header files are changed. Remove the build directory in that case.

Iteration

Use external iterators the following way:

size = ksSize(keySet)
for cursor in range(size):
	key = ksAt(keySet, cursor)
	# ...
