DESCRIPTION

       ERROR: ld.so: object 'libfakeroot-sysv.so' from LD_PRELOAD cannot be preloaded (cannot open shared object
       file): ignored.  USAGE: clang-modernize [options] [<sources>...]

       OPTIONS:

       Formatting Options:

       -format                    - Enable formatting of code changed by applying replacements.
              Use -style to choose formatting style.

       -style=<string>            - Coding style, currently supports:
              LLVM, Google, Chromium, Mozilla, WebKit.

       Use -style=file to load style configuration from
              .clang-format  file  located  in  one  of  the  parent  directories of the source file (or current
              directory for stdin).  Use -style="{key: value, ...}" to set specific parameters, e.g.:

              -style="{BasedOnStyle: llvm, IndentWidth: 8}"

       -style-config=<string>     - Path to a directory containing a .clang-format file
              describing a formatting style to use for formatting code when -style=file.

       Inclusion/Exclusion Options:

       -exclude=<string>          - Comma-separated list of paths that can not be transformed

       -exclude-from=<filename>   - File containing a list of paths that can not be transformed

       -include=<string>          - Comma-separated list of paths to consider to be transformed

       -include-from=<filename>   - File containing a list of paths to consider to be transformed

       Modernizer Options:

       -final-syntax-check        - Check for correct syntax after applying transformations

       -for-compilers=<string>    - Select transforms targeting the intersection of
              language  features  supported  by  the  given  compilers.   Takes  a   comma-separated   list   of
              <compiler>-<version>.

       <compiler> can be any of: clang, gcc, icc, msvc
              <version> is <major>[.<minor>]

       -help                      - Display available options (-help-hidden for more)

       -help-list                 - Display list of available options (-help-list-hidden for more)

       -perf=<directory  name>      -  Capture  performance  data  and  output  to specified directory. Default:
              ./migrate_perf

       -risk                      - Select a maximum risk level:

       =safe  -   Only safe transformations

       =reasonable
              -   Enable transformations that might change semantics (default)

       =risky -   Enable transformations that are likely to change semantics

       -summary                   - Print transform summary

       -version                   - Display the version of this program

       Serialization Options:

       -serialize-dir=<string>    - Path to an existing directory in which to write
              serialized replacements. Default behaviour is to write to a temporary directory.

       -serialize-replacements    - Serialize translation unit replacements to disk instead of changing files.

       Transforms:

       -add-override              - Make use of override specifier where possible

       -loop-convert              - Make use of range-based for loops where possible

       -pass-by-value             - Pass parameters by value where possible

       -replace-auto_ptr          - Replace std::auto_ptr (deprecated) by std::unique_ptr (EXPERIMENTAL)

       -use-auto                  - Use of 'auto' type specifier

       -use-nullptr               - Make use of nullptr keyword where possible

       Transforms' options:

       -override-macros           - Detect and use macros that expand to the 'override' keyword.

       -user-null-macros=<string> - Comma-separated list of user-defined macro names that behave like NULL

       -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: http://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.

       EXAMPLES:

       Apply all transforms on a file that doesn't require compilation arguments:

              clang-modernize file.cpp

       Convert for loops to ranged-based for loops for all files in the compilation database that  belong  in  a
       project subtree and then reformat the code automatically using the LLVM style:

              clang-modernize -p build/path -include project/path -format -loop-convert

       Make use of both nullptr and the override specifier, using git ls-files:

              git ls-files '*.cpp' | xargs -I{} clang-modernize -p build/path \

       -use-nullptr -add-override -override-macros {}

       Apply all transforms supported by both clang >= 3.0 and gcc >= 4.7 to foo.cpp and any included headers in
       bar:

              clang-modernize -for-compilers=clang-3.0,gcc-4.7 foo.cpp \

       -include bar -- -std=c++11 -Ibar
