C-family Semantic Completion ~ C-family Semantic Completion ~
In order to perform semantic analysis such as code completion, |GoTo| and
diagnostics, YouCompleteMe uses 'libclang'. This is the library version of the
clang compiler, sometimes also referred to as llvm. Like any compiler,
'libclang' requires a set of compile flags in order to parse your code. Simply
put: If 'libclang' can't parse your code, YouCompleteMe can't provide semantic
analysis.
There are 2 methods which can be used to provide compile flags to 'libclang':
-------------------------------------------------------------------------------
*youcompleteme-option-1-use-compilation-database-44*
Option 1: Use a compilation database [44] ~
The easiest way to get YCM to compile your code is to use a compilation
database. A compilation database is usually generated by your build system
(e.g. 'CMake') and contains the compiler invocation for each compilation unit
in your project.
For information on how to generate a compilation database, see the clang
documentation [44]. In short:
- If using CMake, add '-DCMAKE_EXPORT_COMPILE_COMMANDS=ON' when configuring
(or add 'set( CMAKE_EXPORT_COMPILE_COMMANDS ON )' to 'CMakeLists.txt') and
copy or symlink the generated database to the root of your project.
- If using Ninja, check out the 'compdb' tool ('-t compdb') in its docs [45].
- If using GNU make, check out Bear [46].
- For other build systems, check out '.ycm_extra_conf.py' below.
If no '.ycm_extra_conf.py' is found, and no 'ycm_global_ycm_extra_conf' is
configured, YouCompleteMe automatically tries to load a compilation database if
one is found.
YCM looks for a file named 'compile_commands.json' in the directory of the
opened file or in any directory above it in the hierarchy (recursively); when
the file is found, it is loaded. YouCompleteMe performs the following lookups
when extracting flags for a particular file:
- If the database contains an entry for the file, the flags for that file are
used.
- If the file is a header file and a source file with the same root exists in
the database, the flags for the source file are used. For example, if the
file is '/home/Test/project/src/lib/something.h' and the database contains
an entry for '/home/Test/project/src/lib/something.cc', then the flags for
'/home/Test/project/src/lib/something.cc' are used.
- Otherwise, if any flags have been returned from the directory containing
the requested file, those flags are used. This heuristic is intended to
provide potentially working flags for newly created files.
Finally, YCM converts any relative paths in the extracted flags to absolute
paths. This ensures that compilation can be performed from any Vim working
directory.
-------------------------------------------------------------------------------
*youcompleteme-option-2-provide-flags-manually*
Option 2: Provide the flags manually ~
If you don't have a compilation database, or aren't able to generate one, you
have to tell YouCompleteMe how to compile your code some other way.
Every c-family project is different. It is not possible for YCM to guess what
compiler flags to supply for your project. Fortunately, YCM provides a
mechanism for you to generate the flags for a particular file with _arbitrary
complexity_. This is achieved by requiring you to provide a Python module which
implements a trival function which, given the file name as argument, returns a
list of compiler flags to use to compile that file.
YCM looks for a '.ycm_extra_conf.py' file in the directory of the opened file YCM looks for a '.ycm_extra_conf.py' file in the directory of the opened file
or in any directory above it in the hierarchy (recursively); when the file is or in any directory above it in the hierarchy (recursively); when the file is
found, it is loaded (only once!) as a Python module. YCM calls a 'FlagsForFile' found, it is loaded (only once!) as a Python module. YCM calls a 'FlagsForFile'

See YCM's own '.ycm_extra_conf.py' [44] for details on how this works. You **NOTE**: It is highly recommended to include '-x <language>' flag to libclang.
This is so that the correct language is detected, particularly for header
files. Common values are '-x c' for C, '-x c++' for C++ and '-x objc' for
Objective-C.
To give you an impression, if your c++ project is trivial, and your usual
compilation command is: 'g++ -Wall -Wextra -Werror -o FILE.o FILE.cc', then the
following '.ycm_extra_conf.py' is enough to get semantic analysis from
YouCompleteMe:
>
def FlagsForFile( filename, **kwargs ):
return {
'flags': [ '-x', 'c++', '-Wall', '-Wextra', '-Werror' ],
}
<
As you can see from the trivial example, YCM calls the 'FlagsForFile' method,
passing it the file name. The '**kwargs' is for advanced users and can usually
be ignored. The 'FlagsForFile' function returns a dictionary with a single
element "'flags'". This element is a 'list' of compiler flags to pass to
libclang for the file 'filename'. That's it! This is actually enough for most
projects, but for complex projects it is not uncommon to integrate directly
with an existing build system using the full power of the Python language.
For a more elaborate example, see YCM's own '.ycm_extra_conf.py' [47]. You
should be able to use it _as a starting point_. **Don't** just copy/paste that should be able to use it _as a starting point_. **Don't** just copy/paste that
