c-picker
========
c-picker uses ``libclang``'s Python interface for parsing source files.
Command line options
--------------------
- ``-h, --help`` - Showing help message
- ``--root ROOT`` - Root source directory
- ``--config CONFIG`` - Configuration file (``.json|.yml``)
- ``--output OUTPUT`` - Output file
- ``--print-dependencies`` - Prints the dependencies
- ``--version`` - Shows the program's version number and exit
- ``--args ...`` - clang arguments
Configuration file format
-------------------------
c-picker configuration can be described in ``JSON`` or ``YAML`` format using the same object structure.
- ``elements`` - List of elements to pick from the original code
- ``name`` - Name of the element
- ``type`` - Type of the element: ``include``, ``function``, ``variable``
- ``args`` - Arguments for clang used during picking the element
- ``options`` - Currenly the only options is ``remove_static`` which removes
the ``static`` qualifier from the element's definition.
- ``options`` - Global options for all elements
- ``args`` - Global clang arguments for all elements
YAML example
------------
YAML format is preferred because it can contain metadata like comments and licence information.
.. code-block:: YAML
elements:
- file: bl1/bl1_fwu.c
type: variable
name: bl1_fwu_loaded_ids
options: [remove_static]
- file: bl1/bl1_fwu.c
type: function
name: bl1_fwu_add_loaded_id
options: [remove_static]
- file: bl1/bl1_fwu.c
type: function
name: bl1_fwu_remove_loaded_id
options: [remove_static]
args:
- -DFWU_MAX_SIMULTANEOUS_IMAGES=10
- -DINVALID_IMAGE_ID=0xffffffff
