9. License |clang_complete-license|
Author: Xavier Deguillard *clang_complete-author*
==============================================================================
1. Description *clang_complete-description*
This plugin use clang for accurately completing C and C++ code.
Note: This plugin is incompatible with omnicppcomplete due to the
unconditionnaly set mapping done by omnicppcomplete. So don't forget to
suppress it before using this plugin.
==============================================================================
2. Completion kinds *clang_complete-compl_kinds*
Because libclang provides a lot of information about completion, there are
some additional kinds of completion along with standard ones (see >
:help complete-items
for details):
'+' - constructor
'~' - destructor
'e' - enumerator constant
'a' - parameter ('a' from "argument") of a function, method or template
'u' - unknown or buildin type (int, float, ...)
'n' - namespace or its alias
'p' - template ('p' from "pattern")
==============================================================================
3. Configuration *clang_complete-configuration*
Each project can have a .clang_complete at his root, containing the compiler
options. This is useful if you're using some non-standard include paths. For
simplicity, please don't put relative and absolute include path on the same
line. It is not currently correctly handled.
==============================================================================
4. Options *clang_complete-options*
*clang_complete-auto_select*
*g:clang_auto_select*
If equal to 0, nothing is selected.
If equal to 1, automatically select the first entry in the popup menu, but
without inserting it into the code.
If equal to 2, automatically select the first entry in the popup menu, and
insert it into the code.
Default: 0
*clang_complete-complete_auto*
*g:clang_complete_auto*
If equal to 1, automatically complete after ->, ., ::
Default: 1
*clang_complete-copen*
*g:clang_complete_copen*
If equal to 1, open quickfix window on error.
Default: 0
*clang_complete-hl_errors*
*g:clang_hl_errors*
If equal to 1, it will highlight the warnings and errors the same way clang
does it.
Default: 1
*clang_complete-periodic_quickfix*
*g:clang_periodic_quickfix*
If equal to 1, it will periodically update the quickfix window.
Default: 0
Note: You could use the g:ClangUpdateQuickFix() to do the same with a mapping.
*clang_complete-snippets*
*g:clang_snippets*
If equal to 1, it will do some snippets magic after a ( or a , inside function
call. Not currently fully working.
Default: 0
*clang_complete-snippets_engine*
*g:clang_snippets_engine*
The snippets engine (clang_complete, snipmate, ultisnips... see the snippets
subdirectory).
Default: "clang_complete"
*clang_complete-conceal_snippets*
*g:clang_conceal_snippets*
If equal to 1, vim will use vim 7.3 conceal feature to hide <# and #> which
delimit a snippets.
Default: 1 (0 if conceal not available)
Note: See concealcursor and conceallevel for conceal configuration.
*clang_complete-exec*
*g:clang_exec*
Name or path of clang executable.
Note: Use this if clang has a non-standard name, or isn't in the path.
Default: "clang"
*clang_complete-user_options*
*g:clang_user_options*
Option added at the end of clang command. Useful if you want to filter the
result, or do other stuffs. To ignore the error code returned by clang, set
|g:clang_exec| to `"clang` and |g:clang_user_options| to `2>/dev/null || exit
0"` if you're on *nix, or `2>NUL || exit 0"` if you are on windows.
Default: ""
*clang_complete-auto_user_options*
*g:clang_auto_user_options*
Set sources for user options passed to clang. Available sources are:
- path - use &path content as list of include directories (relative paths are
ignored)
- .clang_complete - use information from .clang_complete file Multiple options
are separated by comma.
Default: "path, .clang_complete"
*clang_complete-use_library*
*g:clang_use_library*
Instead of calling the clang/clang++ tool use libclang directly. This gives
access to many more clang features. Furthermore it automatically caches all
includes in memory. Updates after changes in the same file will therefore be a
lot faster.
Default: 0
*clang_complete-library_path*
*g:clang_library_path*
If libclang.[dll/so/dylib] is not in your library search path, set this to the
absolute path where libclang is available.
Default: ""
*clang_complete-sort_algo*
*g:clang_sort_algo*
How results are sorted (alpha, priority). Currently only works with libclang.
Default: "priority"
*clang_complete-complete_macros*
*g:clang_complete_macros*
If clang should complete preprocessor macros and constants.
Default: 0
*clang_complete-complete_patterns*
*g:clang_complete_patterns*
If clang should complete code patterns, i.e loop constructs etc.
Defaut: 0
==============================================================================
5. Known issues *clang_complete-issues*
If you find that completion is slow, please read the |clang_complete-pch|
section below.
If you get following error message while trying to complete anything: >
E121: Undefined variable: b:should_overload
it means that your version of Vim is too old (this is an old bug and it has
been fixed with one of patches for Vim 7.2) and you need to update it.
If clang is not able to compile your file, it cannot complete anything. Since
clang is not supporting every C++0x features, this is normal if it can do any
completion on C++0x file.
There is no difference in clang's output between private methods/members and
public ones. Which means that I cannot filter private methods on the
completion list.
==============================================================================
6. PCH *clang_complete-pch*
In case you can not or you do not want to install libclang, a precompiled
header file is another way to accelerate compilation, and so, to accelerate
the completion. It is however more complicated to install and is still slower
than the use of libclang.
Here is how to create the pch, on linux (OSX users may use
-fnext-runtime instead of -fgnu-runtime): >
clang -x c++-header /path/to/c++/vector -fno-exceptions -fgnu-runtime \
-o vector.pch
You just have to insert it into your .clang_complete: >
echo '-include-pch /path/to/vector.pch -fgnu-runtime' >> .clang_complete
<
One of the major problem is that you cannot include more that one pch, the
solution is to put the system headers or non changing headers into another
header and then compile it to pch: >
echo '#include \n#include ' > pchheader.h
clang -x c++-header ./pchheader.h -fno-exceptions -fnu-runtime \
-o ./pchheader.pch
And then add it to the .clang_complete file.
==============================================================================
7. cc_args.py script *clang_complete-cc_args*
This script, installed at ~/.vim/bin/cc_args.py, could be used to generate or
update the .clang_complete file. It works similar to gccsence's gccrec and
simply stores -I and -D arguments passed to the compiler in the
.clang_complete file. Just add the cc_args.py script as the first argument of
the compile command. You should do that every time compile options have
changed.
Example (we need -B flag to force compiling even if project is up to date): >
make CC='~/.vim/bin/cc_args.py gcc' CXX='~/.vim/bin/cc_args.py g++' -B
After running this command, .clang_complete will be created or updated with
new options. If you don't want to update an existing configuration file,
delete it before running make.
==============================================================================
8. To do *clang_complete-todo*
- Write some unit tests
- clang vs libclang accuracy for complex completions
- clang vs libclang timing
- Explore "jump to declaration/definition" with libclang FGJ
- Think about supertab ( with supertab and clang_auto_select)
- Parse fix-its and do something useful with it

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.
