Help content

dotnet-csharpier

Usage:
  dotnet-csharpier [options] [<directoryOrFile>...]

Arguments:
  <directoryOrFile>  One or more paths to a directory containing C# files to format or a C# file to format. It may be ommited when piping data via stdin.

Options:
  --check                           Check that files are formatted. Will not write any changes.
  --loglevel <loglevel>             Specify the log level - Debug, Information (default), Warning, Error, None [default: Information]
  --no-cache                        Bypass the cache to determine if a file needs to be formatted.
  --no-msbuild-check                Bypass the check to determine if a csproj files references a different version of CSharpier.MsBuild.
  --include-generated               Include files generated by the SDK and files that begin with <autogenerated /> comments
  --fast                            Skip comparing syntax tree of formatted file to original file to validate changes.
  --skip-write                      Skip writing changes. Generally used for testing to ensure csharpier doesn't throw any errors or cause syntax tree validation failures.
  --write-stdout                    Write the results of formatting any files to stdout.
  --pipe-multiple-files             Keep csharpier running so that multiples files can be piped to it via stdin.
  --server                          Run CSharpier as a server so that multiple files may be formatted.
  --server-port <server-port>       Specify the port that CSharpier should start on. Defaults to a random unused port.
  --config-path <config-path>       Path to the CSharpier configuration file
  --compilation-errors-as-warnings  Treat compilation errors from files as warnings instead of errors.
  --version                         Show version information
  -?, -h, --help                    Show help and usage information
