       uglify-js - manual page for uglify-js 2.4.15

DESCRIPTION

       /usr/bin/nodejs  ./bin/uglifyjs  input1.js  [input2.js ...] [options] Use a single dash to
       read input from the standard input.

       NOTE: by default there is no mangling/compression.  Without [options] it will simply parse
       input  files  and  dump  the  AST  with  whitespace  and  comments  discarded.  To achieve
       compression and mangling you need to use `-c` and `-m`.

OPTIONS

       --source-map
              Specify an output file where to generate source map.

       --source-map-root
              The path to the original source to be included in the source map.

       --source-map-url
              The path to the source map to be added in //# sourceMappingURL.   Defaults  to  the
              value passed with --source-map.

       --source-map-include-sources
              Pass this flag if you want to include the content of source files in the source map
              as sourcesContent property.

       --in-source-map
              Input source map, useful if you're compressing JS  that  was  generated  from  some
              other original code.

       --screw-ie8
              Pass  this  flag if you don't care about full compliance with Internet Explorer 6-8
              quirks (by default UglifyJS will try to be IE-proof).

       --expr Parse a single expression, rather than a program (for parsing JSON)

       -p, --prefix
              Skip prefix for original filenames that appear in source maps.  For  example  -p  3
              will drop 3 directories from file names and ensure they are relative paths. You can
              also specify -p relative, which will make UglifyJS figure out itself  the  relative
              paths between original sources, the source map and the output file.

       -o, --output
              Output file (default STDOUT).

       -b, --beautify
              Beautify output/specify output options.

       -m, --mangle
              Mangle names/pass mangler options.

       -r, --reserved
              Reserved names to exclude from mangling.

       -c, --compress
              Enable    compressor/pass    compressor    options.    Pass    options    like   -c
              hoist_vars=false,if_return=false. Use -c  with  no  argument  to  use  the  default
              compression options.

       -d, --define
              Global definitions

       -e, --enclose
              Embed everything in a big function, with a configurable parameter/argument list.

       --comments
              Preserve  copyright  comments  in  the  output.  By  default this works like Google
              Closure, keeping JSDoc-style comments that contain "@license" or  "@preserve".  You
              can  optionally  pass  one of the following arguments to this flag: - "all" to keep
              all comments - a valid JS regexp (needs  to  start  with  a  slash)  to  keep  only
              comments  that  match.   Note  that  currently  not *all* comments can be kept when
              compression is on, because of  dead  code  removal  or  cascading  statements  into
              sequences.

       --preamble
              Preamble  to  prepend  to  the  output.   You can use this to insert a comment, for
              example for licensing information.  This will not be parsed,  but  the  source  map
              will adjust for its presence.

       --stats
              Display operations run time on STDERR.

       --acorn
              Use Acorn for parsing.

       --spidermonkey
              Assume input files are SpiderMonkey AST format (as JSON).

       --self Build itself (UglifyJS2) as a library (implies --wrap=UglifyJS --export-all)

       --wrap Embed  everything  in  a  big  function,  making the ???exports??? and ???global???
              variables available. You need to pass an argument to this  option  to  specify  the
              name that your module will take when included in, say, a browser.

       --export-all
              Only  used when --wrap, this tells UglifyJS to add code to automatically export all
              globals.

       --lint Display some scope warnings

       -v, --verbose
              Verbose

       -V, --version
              Print version number and exit.

       --noerr
              Don't throw an error for unknown options in -c, -b or -m.
