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.

"""Create a TranslationUnit by parsing source.
This is capable of processing source code both from files on the
filesystem as well as in-memory contents.
Command-line arguments that would be passed to clang are specified as
a list via args. These can be used to specify include paths, warnings,
etc. e.g. ["-Wall", "-I/path/to/include"].
In-memory file content can be provided via unsaved_files. This is an
iterable of 2-tuples. The first element is the str filename. The
second element defines the content. Content can be provided as str
source code or as file objects (anything with a read() method). If
a file object is being used, content will be read until EOF and the
read cursor will not be reset to its original position.
options is a bitwise or of TranslationUnit.PARSE_XXX flags which will
control parsing behavior.
index is an Index instance to utilize. If not provided, a new Index
will be created for this TranslationUnit.
To parse source from the filesystem, the filename of the file to parse
is specified by the filename argument. Or, filename could be None and
the args list would contain the filename(s) to parse.
To parse source from an in-memory buffer, set filename to the virtual
filename you wish to associate with this source (e.g. "test.c"). The
contents of that file are then provided in unsaved_files.
If an error occurs, a TranslationUnitLoadError is raised.
Please note that a TranslationUnit with parser errors may be returned.
It is the caller's responsibility to check tu.diagnostics for errors.
Also note that Clang infers the source language from the extension of
the input filename. If you pass in source code containing a C++ class
declaration with the filename "test.c" parsing will fail.
