NAME

       htmlmin - htmlmin is a configurable HTML Minifier with safety features.

DESCRIPTION

       usage: htmlmin [-h] [-c] [-s] [--remove-all-empty-space]

              [--keep-optional-attribute-quotes]  [-H]  [-k]  [-a  PRE_ATTR]  [-p [TAG [TAG ...]]] [-e ENCODING]
              [INPUT] [OUTPUT]

       Minify HTML

   positional arguments:
       INPUT  File path to html file to minify. Defaults to stdin.

       OUTPUT File path to output to. Defaults to stdout.

   optional arguments:
       -h, --help
              show this help message and exit

       -c, --remove-comments
              When set, comments will be removed. They can be kept on an individual basis by starting them  with
              a  '!': <!--! comment -->. The '!' will be removed from the final output. If you want a '!' as the
              leading character of your comment, put two of them: <!--!! comment -->.

       -s, --remove-empty-space
              When set, this removes empty space betwen tags in certain cases.   Specifically,  it  will  remove
              empty  space  if  and  only  if there a newline character occurs within the space. Thus, code like
              '<span>x</span> <span>y</span>' will be left alone, but code such as '   ...

       </head>
              <body>

       ...'   will become '...</head><body>...'. Note that this CAN break your html if  you  spread  two  inline
              tags over two lines. Use with caution.

       --remove-all-empty-space
              When  set,  this  removes  ALL  empty  space  betwen tags. WARNING: this can and likely will cause
              unintended consequences. For instance, '<i>X</i> <i>Y</i>' will become '<i>X</i><i>Y</i>'. Putting
              whitespace  along  with  other  text will avoid this problem. Only use if you are confident in the
              result. Whitespace is not removed from inside of tags, thus '<span> </span>' will be left alone.

       --keep-optional-attribute-quotes
              When set, this keeps all attribute quotes, even if they are optional.

       -H, --in-head
              If you are parsing only a fragment of HTML, and the fragment occurs in the head of  the  document,
              setting this will remove some extra whitespace.

       -k, --keep-pre-attr
              HTMLMin  supports  the  propietary  attribute  'pre'  that  can  be  added  to elements to prevent
              minification. This attribute is removed by default. Set this flag to keep the 'pre' attributes  in
              place.

       -a PRE_ATTR, --pre-attr PRE_ATTR
              The  attribute  htmlmin looks for to find blocks of HTML that it should not minify. This attribute
              will be removed from the HTML unless '-k' is specified. Defaults to 'pre'.

       -p [TAG [TAG ...]], --pre-tags [TAG [TAG ...]]
              By default, the contents of 'pre', and 'textarea' tags  are  left  unminified.   You  can  specify
              different tags using the --pre-tags option. 'script' and 'style' tags are always left unmininfied.

       -e ENCODING, --encoding ENCODING
              Encoding  to  read  and  write with. Default 'utf-8'. When reading from stdin, attempts to use the
              system's encoding before defaulting to utf-8.
