       closure-compiler - optimising compiler for ECMAScript (JavaScript) programs


       closure-compiler [ OPTION ... ]
       closure-compiler --help


       The  Closure  Compiler  Application is the command-line interface to the Closure Compiler,
       part of the Closure Tools project.

       The Closure Compiler is a tool for making ECMAScript (JavaScript) download and run faster.
       It  parses your program, analyzes it, removes dead code, and rewrites and minimizes what's
       left. It also checks syntax, variable  references,  and  types,  and  warns  about  common


          Describe how to use the Closure Compiler Application.

          Print the Closure Compiler version to stderr.

          Allow usage of const keyword.

          Generate $inject properties for AngularJS for functions annotated with @ngInject.

       --charset CHARSET
          Specify CHARSET to be the input and output charset for all files. By default, we accept
          UTF-8 as input and output US_ASCII.

       --closure_entry_point ENTRYPOINT
          Specify entry point ENTRYPOINT to the program.  Must  be  goog.provide'd  symbols.  Any
          goog.provide'd symbols that are not a transitive dependency of the entry points will be
          removed. Files without goog.provides, and their dependencies, will always be  left  in.
          If  any entry points are specified, then the manage_closure_dependencies option will be
          set to true and all files will be sorted in dependency order.

       --common_js_entry_module MODULEFILE
          Specify the root of your common JS dependency hierarchy to  be  MODULEFILE.  Your  main

       --common_js_module_path_prefix PREFIX
          Specify a path prefix PREFIX to be removed from CommonJS module names.

       --compilation_level LEVEL
          Set the compilation level to LEVEL.


          Specify  that  variable  renaming  and  property renaming map files will be produced as
          {binary name}_vars_map.out and {binary name}_props_map.out.

          Note that this flag cannot be used in conjunction with either  variable_map_output_file
          or property_map_output_file.

       --create_source_map MAPFILE
          Specify  a  source  map  file  MAPFILE,  mapping the generated source files back to the
          original source file will be output to the specified path.  The  %outname%  placeholder
          will expand to the name of the output file that the source map corresponds to.

          Enable debugging options.

          Override  the  value  of  a  variable  annotated  @define.  The format of DEFINITION is
          <name>[=<val>], where <name> is the name of a @define variable and <val> is a  boolean,
          number,  or  a  single-quot  ed  string  that contains no single quotes. If [=<val>] is
          omitted, the variable is marked true.

       --externs EXTERNFILE
          Specify that the file EXTERNFILE contains JavaScript externs.

          You may specify this option multiple times to specify additional EXTERNFILE files.

       --extra_annotation_name TAGNAME
          Specify TAGNAME to append to the whitelist of tag names in JSDoc.

          You may specify this option multiple times to append additional TAGNAME values.

       --flagfile FILE
          Specify that FILE contains additional command-line options.

       --formatting FORMATOPTION
          Specifies the formatting option FORMATOPTION to apply to the output JS.


          Generates export code for those marked with @export.

       --js INFILE
          Specify INFILE as an input filename.

          You may specify this option multiple times to append additional INFILE names.

       --js_output_file OUTFILE
          Specify OUTFILE as the primary output filename.

          If not specified, output is written to stdout.

       --jscomp_error WARNCLASS
          Make the named class of warnings WARNCLASS an error.

          See Warning Classes, below, for the list of valid WARNCLASS names.

       --jscomp_off WARNCLASS
          Turn off the named class of warnings WARNCLASS.

          See Warning Classes, below, for the list of valid WARNCLASS names.

       --jscomp_warning WARNCLASS
          Make the named class of warnings WARNCLASS a normal warning.

          See Warning Classes, below, for the list of valid WARNCLASS names.

       --language_in LANGSPEC
          Specify the input sources conform to the language LANGSPEC.


       --logging_level LEVEL
          Specify LEVEL as the logging  level  (standard  java.util.  logging.Level  values)  for
          Compiler  progress.  Does  not control errors or warnings for the JavaScript code under

          Automatically sort dependencies so that a file that goog.provides symbol X will  always
          come before a file that goog.requires symbol X. If an input provides symbols, and those
          symbols are never required, then that input will not be included in the compilation.

       --module MODULESPEC
          Specify the JavaScript module specification MODULESPEC.

          The format for MODULESPEC  is  <name>:<num-js-files>[:[<dep>,...][:]]].   Module  names
          must  be  unique. Each dep is the name of a module that this module depends on. Modules
          must be listed in dependency  order,  and  JS  source  files  must  be  listed  in  the
          corresponding  order.  Where  --module  flags  occur  in  relation  to  --js  flags  is
          unimportant.  Provide the value auto to trigger module creation from CommonJSmodules.

       --module_output_path_prefix PREFIX
          Specify  the  filename  prefix  PREFIX  for   filenames   of   compiled   JS   modules.
          <module-name>.js  will  be  appended  to  this  prefix.  Directories will be created as
          needed. Use with --module.

       --module_wrapper WRAPPER
          Specify WRAPPER as output wrapper for a JavaScript module (optional).

          The format of WRAPPER is <name>:<wrapper>. The  module  name  must  correspond  with  a
          module  specified  using --module. The wrapper must contain %s as the code placeholder.
          The %basename% placeholder can also be used to substitute the base name of  the  module
          output file.

          Only  include  files  in  the  transitive  dependency of the entry points (specified by
          closure_entry_point). Files that do not provide  dependencies  will  be  removed.  This
          supersedes manage_closure_dependencies.

       --output_manifest MANIFESTFILE
          Prints out a list of all the files in the compilation to MANIFESTFILE.

          If  --manage_closure_dependencies  is  on, this will not include files that got dropped
          because they were not required.

          The  %outname%  placeholder  expands  to  the  JS  output   file.   If   you're   using
          modularization, using %outname% will create a manifest for each module.

       --output_module_dependencies DEPFILE
          Prints out a JSON file DEPFILE of dependencies between modules.

       --output_wrapper WRAPPER
          Interpolate  output into WRAPPER at the place denoted by the marker token %output%. Use
          marker token %output|jsstring% to do js string escaping on the output.

          Print a dot file describing the internal abstract syntax tree and exit.

          Print a dot file describing the passes that will get run and exit.

          Print out the parse tree and exit.

          Processes built-ins from the Closure library, such as  goog.require(),  goog.provide(),
          and goog.exportSymbol().

          Process CommonJS modules to a concatenable form.

          Processes built-ins from the JQuery library, such as jQuery.fn and jQuery.extend().

       --property_map_input_file MAPFILE
          Specify  MAPFILE  as  containing  the  serialized  version of the property renaming map
          produced by a previous compilation.

       --property_map_output_file MAPFILE
          Save the serialized version of the property renaming map produced to MAPFILE.

       --source_map_format FORMAT
          Product the source map in format FORMAT.

          Values: V1, V2, V3, DEFAULT. DEFAULT produces V2.

       --summary_detail_level LEVEL
          Specify the compilation summary detail level LEVEL.

          Values: 0 (never print  summary),  1  (print  summary  only  if  there  are  errors  or
          warnings),  2  (print  summary  if  the  'checkTypes'  diagnostic group is enabled, see
          --jscomp_warning), 3 (always print summary). The default level is 1.

          Check source validity but do not enforce Closure style rules and conventions.

          Transform AMD to CommonJS modules.

       --translations_file TRANSFILE
          Specify TRANSFILE as the source of translated messages. Currently only supports XTB.

       --translations_project PROJECT
          Scope all translations to the specified project.

          When specified, use different message ids so that messages in  different  projects  can
          have different translations.

          Specifies that the default externs should be excluded.

          Experimental:   perform   additional  optimizations  based  on  available  information.
          Inaccurate type annotations may result in incorrect results.

       --variable_map_input_file MAPFILE
          Specify MAPFILE as containing the serialized  version  of  the  variable  renaming  map
          produced by a previous compilation.

       --variable_map_output_file MAPFILE
          Save the serialized version of the variable renaming map produced to MAPFILE.

       --warning_level LEVEL
          Specify the warning level to use.

          Values: QUIET, DEFAULT, VERBOSE.

       --warnings_whitelist_file LISTFILE
          Suppress   warnings   listed   in   LISTFILE.   Each   line   should  be  of  the  form
          <file-name>:<line-number>? <warning-d escription>

   Warning Classes
       The jscomp_error, jscomp_warning, and jscomp_off flags require as a parameter a  WARNCLASS
       warning class name. The following names are valid warning class names:
