Many scripts are written using Python so it useful to have Python bindings for libfdt. Apparently this has never been attempted before, or if so I cannot find a reference. This series starts the process of adding this support, with just a bare-bones set of methods, to attract initial comments. The v3 series makes the binding more pythonic, allowing things like: fdt = libfdt.Fdt(open(fname).read()) node = fdt.path('/subnode@1') print node.prop('compatible').data() subnode = node.first_subnode_quiet() while subnode: print subnode.name() subnode = subnode.next_subnode_quiet() There are still some open question, particularly around naming. Changes in v3: - Make the library more pythonic - Add classes for Node and Prop along with methods - Add an exception class - Use Python to generate exeptions instead of SWIG Changes in v2: - Add exceptions when functions return an error - Correct Python naming to following PEP8 - Use a class to encapsulate the various methods - Include fdt.h instead of redefining struct fdt_property - Use bytearray to avoid the SWIG warning 454 - Add comments - Update tests for new pylibfdt - Add a few more tests to increase coverage - Add some more tests - Add details on how to obtain full help and code coverage Simon Glass (4): Add an initial Python library for libfdt Add tests for pylibfdt Mention pylibfdt in the documentation Build pylibfdt as part of the normal build process Makefile | 16 +- README | 33 +++ pylibfdt/.gitignore | 3 + pylibfdt/Makefile.pylibfdt | 18 ++ pylibfdt/libfdt.swig | 602 +++++++++++++++++++++++++++++++++++++++++++++ pylibfdt/setup.py | 34 +++ tests/pylibfdt_tests.py | 389 +++++++++++++++++++++++++++++ tests/run_tests.sh | 19 +- 8 files changed, 1112 insertions(+), 2 deletions(-) create mode 100644 pylibfdt/.gitignore create mode 100644 pylibfdt/Makefile.pylibfdt create mode 100644 pylibfdt/libfdt.swig create mode 100644 pylibfdt/setup.py create mode 100644 tests/pylibfdt_tests.py -- 2.8.0.rc3.226.g39d4020
