DESCRIPTION

       USAGE: clang-check [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-check options:

       --analyze                       - Run static analysis engine

       --analyzer-output-path=<string> - Write output to <file>

       --ast-dump                      - Build ASTs and then debug dump them

       --ast-dump-filter=<string>      - Use with -ast-dump or -ast-print to dump/print only  AST
              declaration  nodes having a certain substring in a qualified name. Use -ast-list to
              list all filterable declaration node names.

       --ast-list                      - Build ASTs  and  print  the  list  of  declaration  node
              qualified names

       --ast-print                     - Build ASTs and then pretty-print them

       --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

       --fix-what-you-can               -  Apply  fix-it advice even in the presence of unfixable
              errors

       --fixit                         - Apply fix-it advice to the input source

       -p <string>                     - Build path

       --syntax-tree-dump              - dump the syntax tree

       --tokens-dump                   - dump the preprocessed tokens

       -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.

              For example, to run clang-check on all files in a subtree of the source tree, use:

              find path/in/subtree -name '*.cpp'|xargs clang-check

              or using a specific build path:

              find path/in/subtree -name '*.cpp'|xargs clang-check -p build/path

              Note, that path/in/subtree and current directory should follow the rules  described
              above.
