data tree CHANGE store with-defaults attribute as flag in data node instead of creating full data attribute on LYD_WD_*_TAG, just set flag in data node. The XML/JSON attribute appears while the node is being printed (the attribute is not created, it is actually just printed).

libyang
libyang is YANG data modelling language parser and toolkit written (and providing API) in C.
Provided Features
- Parsing (and validating) schemas in YANG format.
- Parsing (and validating) schemas in YIN format.
- Parsing, validating and printing instance data in XML format.
- Parsing, validating and printing instance data in JSON format.
- Manipulation with the instance data.
- Support for adding default values into instance data.
Planned Features
- parsing (and validating) data models in YANG format
Requirements
- cmake >= 2.6
- libpcre
- cmocka >= 1.0.0 (for tests only, see Tests)
Building
$ mkdir build; cd build $ cmake .. $ make # make install
Documentation
The library documentation can be generated directly from the source codes using Doxygen tool:
$ make doc
Useful CMake Options
Changing Compiler
Set CC variable:
$ CC=/usr/bin/clang cmake ..
Changing Install Path
To change the prefix where the library, headers and any other files are installed, set CMAKE_INSTALL_PREFIX variable:
$ cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr ..
Default prefix is /usr/local.
Build Modes
There are two build modes:
- Release. This generates library for the production use without any debug information.
- Debug. This generates library with the debug information and disables optimization of the code.
The Debug mode is currently used as the default one. to switch to the Release mode, enter at the command line:
$ cmake -D CMAKE_BUILD_TYPE:String="Release" ..
CMake Notes
Note that, with CMake, if you want to change the compiler or its options after you already ran CMake, you need to clear its cache first - the most simple way to do it is to remove all content from the 'build' directory.
Tests
libyang includes several tests built with cmocka. The tests can be found in tests subdirectory and they are designed for checking library functionality after code changes.
The tests are by default built in the Debug build mode by running
$ make
In case of the Release mode, the tests are not built by default (it requires additional dependency), but it can be enabled via cmake option:
$ cmake -DENABLE_BUILD_TESTS=ON ..
Note that if the necessary cmocka headers are not present in the system include paths, tests are not available despite the build mode or cmake's options.
Tests can be run by the make's test target:
$ make test
Bindings
We provide bindings for high-level languages using SWIG generator. The bindings are optional and to enable building of the specific binding, the appropriate cmake option must be enabled, for example:
$ cmake -DJAVASCRIPT_BINDING=ON ..
More information about the specific binding can be found in their README files.
Currently supported bindings are:
- JavaScript
- cmake option:
JAVASCRIPT_BINDING - README
yanglint
libyang source codes include a simple example tool to demanstrate how an application can work with the libyang library. The tool is called yanglint. It is not being installed together with the library itself, but it is built together with the library binary and you can find it in tools/lint directory.
There is also README describing some examples of using yanglint.
