See LICENSE.TXT for details. # #===------------------------------------------------------------------------===# r""" Clang Indexing Library Bindings =============================== This module provides an interface to the Clang indexing library. It is a low-level interface to the indexing library which attempts to match the Clang API directly while also being "pythonic". Notable differences from the C API are: * string results are returned as Python strings, not CXString objects. * null cursors are translated to None. * access to child cursors is done via iteration, not visitation. The major indexing objects are: Index The top-level object which manages some global library state. TranslationUnit High-level object encapsulating the AST for a single translation unit. These can be loaded from .ast files or parsed on the fly. Cursor Generic object for representing a node in the AST. SourceRange, SourceLocation, and File Objects representing information about the input source. Most object information is exposed using properties, when the underlying API call is efficient. """ # TODO # ==== # # o API support for invalid translation units. Currently we can't even get the # diagnostics on failure because they refer to locations in an object that # will have been invalidated. # # o fix memory management issues (currently client must hold on to index and # translation unit, or risk crashes). # # o expose code completion APIs. # # o cleanup ctypes wrapping, would be nice to separate the ctypes details more # clearly, and hide from the external interface (i.e., help(cindex)). # # o implement additional SourceLocation, SourceRange, and File methods. from ctypes import * import collections def get_cindex_library(): # FIXME: It's probably not the case that the library is actually found in # this location.
