At present libfdt consists of only a C implementation. 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.
The v4 series provides binding that can be used like this:
fdt = libfdt.Fdt(open(fname).read())
node = fdt.path_offset('/subnode@1')
print fdt.get_prop(node, 'compatible')
subnode = fdt.first_subnode_quiet(node)
while subnode > 0:
print fdt.get_name(subnode)
subnode = fdt.next_subnode_quiet(subnode)
This version does not include a class for properties. That can be added
if it is felt to be useful, but I want to get some basic functionality
agreed first. The get_property_by_offset() function would likely benefit
from this.
Changes in v4:
- Make the library less pythonic to avoid a shaky illusion
- Drop classes for Node and Prop, along with associated methods
- Include libfdt.h instead of repeating it
- Add support for fdt_getprop()
- Bring in all libfdt functions (but Python support is missing for many)
- Add full comments for Python methods
- Drop tests that are no-longer applicable
- Add a get for getprop()
- Add new patch to adjust libfdt.h to work with swig
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
- Add some more tests
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 details on how to obtain full help and code coverage
