closure-compiler closure-compiler 1 closure-compiler Performs checking, instrumentation, and optimization on JavaScript code. closure-compiler OPTIONS FILES closure-compiler may be used to check and optimize JavaScript code. If positional arguments are not given, code to check will be read from standard input. The following options are understood: --accept_const_keyword Allows usage of const keyword. --angular_pass Generate $inject properties for AngularJS for functions annotated with @ngInject. --charset VAL Input and output charset for all files. By default, we accept UTF-8 as input and output US_ASCII. --closure_entry_point VAL Entry points 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.provide's, 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 VAL Root of your common JS dependency hierarchy. Your main script. --common_js_module_path_prefix VAL Path prefix to be removed from CommonJS module names. --compilation_level WHITESPACE_ONLY|SIMPLE_OPTIMIZATIONS|ADVANCED_OPTIMIZATIONS Specifies the compilation level to use. --create_name_map_files If true, 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 variableMapOut putFile or property_map_output_file. --create_source_map VAL If specified, a source map file 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. --debug Enable debugging options. --D --d --define name=val Override the value of a variable annotated @define. The format is name=val, where name is the name of a @define variable and val is a boolean, number, or a single-quoted string that contains no single quotes. If val is omitted, the variable is marked true. --externs VAL The file containing JavaScript externs. May be specified multiple times. --extra_annotation VAL A whitelist of tag names in JSDoc. May be specified multiple times. --flagfile VAL A file containing additional command-line options. --formatting PRETTY_PRINT | PRINT_INPUT_DELIMITER | SINGLE_QUOTES Specifies which formatting options, if any, should be applied to the output JS. --generate_exports Generates export code for those marked with @export. --help Displays this message --js VAL The JavaScript filename. May be specified multiple times. --js_output_file VAL Primary output filename. If not specified, output is written to stdout. --jscomp_error VAL Make the named class of warnings an error. Options: accessControls, ambiguousFunctionDecl, checkEventfulObjectDisposal, checkRegExp, checkStruct DictInheritance, checkTypes, checkVars, const, constantProperty, deprecated, duplicateMessage, es3, es5Strict, externsValidation, fileoverviewTags, globalThis, internetExplorerChecks, invalidCasts, misplacedTypeAnnotation, missingProperties, missingProvide, missingRequire, missingReturn, nonStandardJsDocs, reportUnknownTypes, suspiciousCode, strictModuleDepCheck, typeInvalidation, undefinedNames, undefinedVars, unknownDefines, uselessCode, visibility. --jscomp_off VAL Turn off the named class of warnings. Options: accessControls, ambiguousFunctionDecl, checkEventfulObjectDisposal, checkRegExp, checkStructDictInheritance, checkTypes, checkVars, const, constantProperty, deprecated, duplicateMessage, es3, es5Strict, externsValidation, fileoverviewTags, globalThis, internetExplorerChecks, invalidCasts, misplacedTypeAnnotation, missingProperties, missingProvide, missingRequire, missingReturn, nonStandardJsDocs, reportUnknownTypes, suspiciousCode, strictModuleDepCheck, typeInvalidation, undefinedNames, undefinedVars, unknownDefines, uselessCode, visibility. --jscomp_warning VAL Make the named class of warnings a normal warning. Options: accessControls, ambiguousFunctionDecl, checkEventfulObjectDisposal, checkRegExp, checkStructDictInheritance, checkTypes, checkVars, const, constantProperty, deprecated, duplicateMessage, es3, es5Strict, externsValidation, fileoverviewTags, globalThis, internetExplorerChecks, invalidCasts, misplacedTypeAnnotation, missingProperties, missingProvide, missingRequire, missingReturn, nonStandardJsDocs, reportUnknownTypes, suspiciousCode, strictModuleDepCheck, typeInvalidation, undefinedNames, undefinedVars, unknownDefines, uselessCode, visibility. --language_in VAL Sets what language spec that input sources conform. Options: ECMASCRIPT3 (default), ECMASCRIPT5, ECMASCRIPT5_STRICT. --logging_level VAL The logging level (standard java.util.logging.Level values) for Compiler progress. Does not control errors or warnings for the JavaScript code under compilation --manage_closure_dependencies 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 name:num-js-files:dep...: A JavaScript module specification. 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 VAL 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 VAL An output wrapper for a JavaScript module (optional). The format is name:wrapper. The module name must correspond with a module specified using --module. The wrapper must contain %s as the code placeholde r. The %basename% placeholder can also be used to substitute the base name of the module output file. --new_type_inf In development new type inference pass. DO NOT USE! --only_closure_dependencies 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 VAL Prints out a list of all the files in the compilation. 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 VAL Prints out a JSON file of dependencies between modules. --output_wrapper VAL Interpolate output into this string at the place denoted by the marker token %output%. Use marker token %output|jsstring% to do js string escaping on the output. --print_ast Prints a dot file describing the internal abstract syntax tree and exits. --print_pass_graph Prints a dot file describing the passes that will get run and exits. --print_tree Prints out the parse tree and exits. --process_closure_primitives Processes built-ins from the Closure library, such as goog.require(), goog.provide(), and goog.exportSymbol(). --process_common_js_modules Process CommonJS modules to a concatenable form. --process_jquery_primitives Processes built-ins from the jQuery library, such as jQuery.fn and jQuery.extend(). --property_map_input_file VAL File containing the serialized version of the property renaming map produced by a previous compilation. --property_map_output_file VAL File where the serialized version of the property renaming map produced should be saved. --source_map_format V1 | DEFAULT | V2 | V3 The source map format to produce. Options: V1, V2, V3, DEFAULT. DEFAULT produces V2. --summary_detail_level N Controls how detailed the compilation summary is. 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. --third_party Check source validity but do not enforce Closure style rules and conventions. --tracer_mode ALL | RAW_SIZE | TIMING_ONLY | OFF Shows the duration of each compiler pass and the impact to the compiled output size. Options: ALL, RAW_SIZE, TIMING_ONLY, OFF. --transform_amd_modules Transform AMD to CommonJS modules. --translations_file VAL Source of translated messages. Currently only supports XTB. --translations_project VAL Scopes all translations to the specified project.When specified, we will use different message ids so that messages in different projects can have different translations. --use_only_custom_externs Specifies whether the default externs should be excluded. --use_types_for_optimization Experimental: perform additional optimizations based on available information. Inaccurate type annotations may result in incorrect results. --variable_map_input_file VAL File containing the serialized version of the variable renaming map produced by a previous compilation. --variable_map_output_file VAL File where the serialized version of the variable renaming map produced should be saved. --version Prints the compiler version to stderr. --warning_level QUIET | DEFAULT |VERBOSE Specifies the warning level to use. Options: QUIET, DEFAULT, VERBOSE. --warnings_whitelist_file FILE A file containing warnings to suppress. Each line should be of the form file-name:line-number warning-description. https://code.google.com/p/closure-compiler/
