USAGE: clang-query [options] <source0> [...
<sourceN>]
OPTIONS:
Generic Options:
--help - Display available options (--help-hidden
for more)
--help-list - Display list of available options
(--help-list-hidden for more)
--version - Display the version of this program
clang-query options:
-c <command> - Specify command to run
--extra-arg=<string> - Additional argument to
append to the compiler command line
--extra-arg-before=<string> - Additional argument
to prepend to the compiler command line
-f <file> - Read commands from file
-p <string> - Build path
--preload=<file> - Preload commands from file and
start interactive mode
- --use-color - Use colors
in detailed AST output. If not set, colors
- will be used if the terminal connected to standard output supports
colors.
-p <build-path> is used to read a compile command
database.
- For example, it can be a CMake build directory in which a file named
compile_commands.json exists (use
-DCMAKE_EXPORT_COMPILE_COMMANDS=ON CMake option to get this
output). When no build path is specified, a search for
compile_commands.json will be attempted through all parent paths of the
first input file . See:
https://clang.llvm.org/docs/HowToSetupToolingForLLVM.html for an example
of setting up Clang Tooling on a source tree.
<source0> ... specify the paths of source files. These paths
are
- looked up in the compile command database. If the path of a file is
absolute, it needs to point into CMake's source tree. If the path is
relative, the current working directory needs to be in the CMake source
tree and the file must be in a subdirectory of the current working
directory. "./" prefixes in the relative files will be
automatically removed, but the rest of a relative path must be a suffix of
a path in the compile command database.
