        "description": "header2whatever (h2w)\n=====================\n\nGenerate arbitrary files from C/C++ header files using CppHeaderParser to read\nthe input files and Jinja2 templates to generate the outputs.\n\nThis grew out of a desire to generate pybind11 wrapping code from C++ header\nfiles. pybind11gen was created, but then I wanted to generate more things...\n\nThere are still rough edges, and the documentation is mostly nonexistent, but\npull requests with fixes/improvements are very welcome!\n\nInstall\n-------\n\n::\n\n    pip install header2whatever\n\nUsage\n=====\n\nFirst, you need to create a jinja2 template that represents whatever you want\nto generate from the header file. For example, maybe you want to describe the\nfunctions in yaml::\n\n    ---\n    {% for header in headers %}\n    {% for fn in header.functions %}\n    {{ fn.name }}:\n      returns: {{ fn.returns }}\n      params:\n      {% for param in fn.parameters %}\n      - { name: {{ param.name }}, type: \"{{ param.type }}\" }\n      {% endfor %}\n\n    {% endfor %}\n    {% endfor %}\n\nAnd let's say you have the following header file ``foo.h``::\n\n    void some_fn(int i);\n    int returns_int(int p1, char* p2);\n\nYou can execute the following::\n\n    h2w foo.h -o foo.yml\n\nAnd you'll get the following output::\n\n    ---\n    returns_int:\n      returns: int\n      params:\n      - { name: p1, type: \"int\" }\n      - { name: p2, type: \"char *\" }\n\n    some_fn:\n      returns: void\n      params:\n      - { name: i, type: \"int\" }\n\nAs you can see, while this is a silly example, this approach is very flexible\nand fairly powerful.\n\nCurrently, the data structure passed to the template isn't documented -- but\nit's a filtered version of whatever CppHeaderParser outputs when it parses a\nheader.\n\nSee the examples folder for more examples.\n\nBatch mode\n----------\n\nIf you need to process multiple files, or just want to record the parameters for\nautogenerating a file without writing a shell script, batch mode is useful. You\npass two parameters: a yaml file with the configuration, and an output directory\nto write the files to.\n\n\nUsing data from external sources\n--------------------------------\n\nSometimes you want to mix in data that CppHeaderParser can't give you. If you\npass the ``--yaml`` option, it will load the yaml into a dictionary and make it\navailable to the template as the 'data' variable.\n\nYou can also pass key=value parameters via the ``--param`` option, and\nthe specified keys will be available to the template.\n\nCustom processing\n-----------------\n\nWhen you need to do more complex logic that a jinja2 template just isn't\nappropriate for, you can specify a python file to load custom hooks from.\n\nSee [the default hooks](header2whatever/default_hooks.py) for documentation.\n\nLicense\n=======\n\nApache 2\n\nAuthor\n======\n\nDustin Spicuzza (dustin@virtualroadside.com)\n",
