This module is private; the command line is the only supported interface. Two subcommands: ``exec-python`` Execute a Python script that constructs a :class:`cffi.FFI` (the same kind of script that the CFFI docs' "Main mode of usage" describes) and emit the generated C source. ``read-sources`` Create the :class:`cffi.FFI` from a separate ``cdef`` file and C source prelude, then emit the generated C source.

The script is executed with ``__name__`` set to ``"cffi.gen_src"``, so a trailing ``if __name__ == "__main__": ffibuilder.compile()`` block in the script is skipped. ``ffivar`` is the name bound by the script to the :class:`FFI` object, or to a callable that returns one. Raises :class:`NameError` if the name is not bound by the script, or :class:`TypeError` if the name does not resolve to an :class:`FFI` instance. z cffi.gen_src)__name____file__NrzGExpected to find the FFI object with the name %r, but it was not found.zKFound an object with the name %r but it was not an instance of cffi.api.FFI) ospathabspathsysinsertdirnamer NameError isinstancercallable TypeError)r rffivarr old_pathffir r r find_ffi_in_python_script8s.     rcCs t}||||||S)zACreate an :class:`FFI` from ``cdef`` text and a C source prelude.)rcdef set_source) modulenamercsrc ffibuilderr r r make_ffi_from_sources_s  r$cCst}|||S)z=Return the C source that :meth:`FFI.emit_c_code` would write.)ioStringIO emit_c_codegetvalue)routputr r r generate_c_sourcegs r*cCsV|dkr tj|dSt|ddd}||WddS1s$wYdS)N-wutf-8encoding)rstdoutwriteopen)r) generatedfr r r write_c_sourcens   "r5cCs6||urdSz tj|j|jWStyYdSw)NTF)rrsamefilenameOSError)file1file2r r r same_input_filevs r;cCsL|t||j|}Wdn1swYt|}t||dSN)rreadr7r*r5)r)pyfileffi_varrr3r r r exec_pythons r@c Csz|"||}|}Wdn1swYWdn1s'wYt|||}t|}t||dSr<)r=r$r*r5)r) module_name cdef_input csrc_inputr"rrr3r r r read_sourcess   rDcCs.tjr tjtjdnd}|drdSdS)Nrz cffi-gen-srczpython -m cffi.gen_src)rargvrrbasename startswith)argv0r r r _progs rJz-Generate CFFI C source for extension modules.)prog descriptionr)dest exec-pythonz2Execute a Python script that defines an FFI object)helpz --ffi-varr#zFName of the FFI object in the Python script; defaults to 'ffibuilder'.)defaultrOr>rr-r.zPath to the Python script)typerOr)zOutput path for the C source read-sourcesz>Read cdef and C source prelude files that define an FFI objectrAz5Full name of the generated module, including packagesrzFile containing C definitionsr"z File containing C source preludecCstj|d}|jdkrt|j|j|jdn#|jdkr4t|j|j r't dt |j|j |j|j dnt dt ddS) NargsrN)r)r>r?rSz1cdef and csrc are the same file and should not be)r)rArBrCz5a subcommand is required: exec-python or read-sourcesr)parser parse_argsrr@r)r>r?r;rr"errorrDrAexitrTr r r runs     rZr<)__doc__argparser%rrapirrrr$r*r5r;r@rDrJArgumentParserrVadd_subparsers subparsers add_parserexec_python_parser add_argumentFileTyperead_sources_parserrZr r r r sz '
