NAME
clang-query - manual page for clang-query 14
DESCRIPTION
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 com-
piler 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 in-
teractive mode
--use-color - Use colors in detailed AST output. If not
set, colors
will be used if the terminal connected to standard output sup-
ports 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_COM-
PILE_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.
