NAME

       tidy - validate, correct, and pretty-print HTML files
       (version: 25 March 2009)

SYNOPSIS

       tidy [option ...] [file ...] [option ...] [file ...]

DESCRIPTION

       Tidy  reads  HTML,  XHTML  and XML files and writes cleaned up markup.  For HTML variants, it detects and
       corrects many common coding errors and strives to produce visually equivalent markup  that  is  both  W3C
       compliant  and  works  on  most  browsers.  A  common use of Tidy is to convert plain HTML to XHTML.  For
       generic XML files, Tidy is limited to correcting basic well-formedness errors and pretty printing.

       If no input file is specified, Tidy reads the standard input.  If  no  output  file  is  specified,  Tidy
       writes  the tidied markup to the standard output.  If no error file is specified, Tidy writes messages to
       the standard error.  For command line options that expect a numerical argument, a default is  assumed  if
       no meaningful value can be found.

USAGE

       Use  --optionX  valueX  for the detailed configuration option "optionX" with argument "valueX".  See also
       below under Detailed Configuration Options as to how to conveniently group all such options in  a  single
       config file.

       Input/Output  default  to  stdin/stdout  respectively.  Single letter options apart from -f and -o may be
       combined as in:

          tidy -f errs.txt -imu foo.html

       For further info on HTML see http://www.w3.org/MarkUp.

       For more information about HTML Tidy, visit the project home page at http://tidy.sourceforge.net.   Here,
       you will find links to documentation, mailing lists (with searchable archives) and links to report bugs.

ENVIRONMENT

       HTML_TIDY
              Name  of the default configuration file.  This should be an absolute path, since you will probably
              invoke tidy from different directories.  The value of HTML_TIDY will be parsed after the compiled-
              in default (defined with -DTIDY_CONFIG_FILE), but before any of the files specified using -config.

EXIT STATUS

       0      All input files were processed successfully.

       1      There were warnings.

       2      There were errors.

DETAILED CONFIGURATION OPTIONS

       This  section describes the Detailed (i.e., "expanded") Options, which may be specified by preceding each
       option with -- at the command line, followed by its desired value, OR by placing the options  and  values
       in a configuration file, and telling tidy to read that file with the -config standard option.

SYNOPSIS

       tidy --option1 value1 --option2 value2 [standard options ...]
       tidy -config config-file [standard options ...]

WARNING

       The  options  detailed here do not include the "standard" command-line options (i.e., those preceded by a
       single '-') described above in the first section of this man page.

DESCRIPTION

       A list of options for configuring the behavior of Tidy, which can be passed either on the  command  line,
       or specified in a configuration file.

       A  Tidy  configuration  file is simply a text file, where each option is listed on a separate line in the
       form

          option1: value1
          option2: value2
          etc.

       The permissible values for a given option depend on the option's Type.  There are  five  types:  Boolean,
       AutoBool,  DocType,  Enum,  and  String.  Boolean  types  allow any of yes/no, y/n, true/false, t/f, 1/0.
       AutoBools allow auto in addition to the values allowed by  Booleans.   Integer  types  take  non-negative
       integers.   String  types  generally  have  no  defaults,  and you should provide them in non-quoted form
       (unless you wish the output to contain the literal quotes).

       Enum, Encoding, and DocType "types" have a fixed repertoire of items;  consult  the  Example[s]  provided
       below for the option[s] in question.

       You  only  need to provide options and values for those whose defaults you wish to override, although you
       may wish to include some  already-defaulted  options  and  values  for  the  sake  of  documentation  and
       explicitness.

       Here is a sample config file, with at least one example of each of the five Types:

           // sample Tidy configuration options
           output-xhtml: yes
           add-xml-decl: no
           doctype: strict
           char-encoding: ascii
           indent: auto
           wrap: 76
           repeated-attributes: keep-last
           error-file: errs.txt

       Below  is  a  summary and brief description of each of the options. They are listed alphabetically within
       each category.  There are five categories: HTML, XHTML, XML options, Diagnostics  options,  Pretty  Print
       options, Character Encoding options, and Miscellaneous options.

OPTIONS

   HTML, XHTML, XML options:
       add-xml-decl

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if Tidy should add the XML declaration when outputting XML or XHTML. Note
              that if the input already includes an <?xml ... ?> declaration then this option will  be  ignored.
              If  the  encoding for the output is different from "ascii", one of the utf encodings or "raw", the
              declaration is always added as required by the XML standard.

                                                                        See also: char-encoding, output-encoding

       add-xml-space

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should add xml:space="preserve" to elements such as  <PRE>,  <STYLE>
              and  <SCRIPT>  when  generating  XML.  This  is needed if the whitespace in such elements is to be
              parsed appropriately without having access to the DTD.

       alt-text

              Type:    String
              Default: -
              Default: -

              This option specifies the default "alt=" text Tidy uses for  <IMG>  attributes.  This  feature  is
              dangerous  as  it  suppresses  further accessibility warnings. You are responsible for making your
              documents accessible to people who can not see the images!

       anchor-as-name

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option controls the deletion or addition of the name attribute in elements where it can serve
              as  anchor. If set to "yes", a name attribute, if not already existing, is added along an existing
              id attribute if the DTD allows it. If set to "no", any existing name attribute is removed if an id
              attribute exists or has been added.

       assume-xml-procins

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies if Tidy should change the parsing of processing instructions to require ?>
              as the terminator rather than >. This option is automatically set if the input is in XML.

       bare

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should strip Microsoft specific HTML from Word 2000  documents,  and
              output spaces rather than non-breaking spaces where they exist in the input.

       clean

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if  Tidy  should  strip  out  surplus  presentational tags and attributes
              replacing them by style rules and structural markup as appropriate. It  works  well  on  the  HTML
              saved by Microsoft Office products.

                                                                                        See also: drop-font-tags

       css-prefix

              Type:    String
              Default: -
              Default: -

              This option specifies the prefix that Tidy uses for styles rules. By default, "c" will be used.

       decorate-inferred-ul

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies if Tidy should decorate inferred UL elements with some CSS markup to avoid
              indentation to the right.

       doctype

              Type:    DocType
              Default: auto
              Example: omit, auto, strict, transitional, user

              This option specifies the DOCTYPE declaration generated by Tidy. If set to "omit" the output won't
              contain  a  DOCTYPE  declaration.  If  set to "auto" (the default) Tidy will use an educated guess
              based upon the contents of the document. If set to "strict", Tidy will  set  the  DOCTYPE  to  the
              strict  DTD. If set to "loose", the DOCTYPE is set to the loose (transitional) DTD. Alternatively,
              you can supply a string for the formal public identifier (FPI).

              For example:
              doctype: "-//ACME//DTD HTML 3.14159//EN"

              If you specify the FPI for an XHTML document, Tidy will set the  system  identifier  to  an  empty
              string.  For  an  HTML  document, Tidy adds a system identifier only if one was already present in
              order to preserve the processing mode of some browsers. Tidy leaves the DOCTYPE  for  generic  XML
              documents  unchanged.  --doctype omit implies --numeric-entities yes. This option does not offer a
              validation of the document conformance.

       drop-empty-paras

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should discard empty paragraphs.

       drop-font-tags

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should  discard  <FONT>  and  <CENTER>  tags  without  creating  the
              corresponding style rules. This option can be set independently of the clean option.

                                                                                                 See also: clean

       drop-proprietary-attributes

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if  Tidy should strip out proprietary attributes, such as MS data binding
              attributes.

       enclose-block-text

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should insert a <P> element to enclose any  text  it  finds  in  any
              element that allows mixed content for HTML transitional but not HTML strict.

       enclose-text

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if Tidy should enclose any text it finds in the body element within a <P>
              element. This is useful when you want to take existing HTML and use it with a style sheet.

       escape-cdata

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should convert <![CDATA[]]> sections to normal text.

       fix-backslash

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should replace backslash characters "\" in URLs by  forward  slashes
              "/".

       fix-bad-comments

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option specifies if Tidy should replace unexpected hyphens with "=" characters when it comes
              across adjacent hyphens. The default is yes. This option is provided  for  users  of  Cold  Fusion
              which uses the comment syntax: <!--- --->

       fix-uri

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should check attribute values that carry URIs for illegal characters
              and if such are found, escape them as HTML 4 recommends.

       hide-comments

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should print out comments.

       hide-endtags

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should omit optional end-tags when  generating  the  pretty  printed
              markup. This option is ignored if you are outputting to XML.

       indent-cdata

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should indent <![CDATA[]]> sections.

       input-xml

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if  Tidy  should use the XML parser rather than the error correcting HTML
              parser.

       join-classes

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should combine class names to generate a single new class  name,  if
              multiple class assignments are detected on an element.

                                                                      See also: join-styles, repeated-attributes

       join-styles

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if Tidy should combine styles to generate a single new style, if multiple
              style values are detected on an element.

                                                                     See also: join-classes, repeated-attributes

       literal-attributes

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should ensure that whitespace characters within attribute values are
              passed through unchanged.

       logical-emphasis

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies if Tidy should replace any occurrence of <I> by <EM> and any occurrence of
              <B> by <STRONG>. In both cases, the attributes are preserved unchanged. This  option  can  be  set
              independently of the clean and drop-font-tags options.

       lower-literals

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if  Tidy  should  convert  the value of an attribute that takes a list of
              predefined values to lower case. This is required for XHTML documents.

       merge-divs

              Type:    AutoBool
              Default: auto
              Example: auto, y/n, yes/no, t/f, true/false, 1/0

              Can be used to modify behavior of -c (--clean yes) option. This option specifies  if  Tidy  should
              merge  nested  <div>  such as "<div><div>...</div></div>". If set to "auto", the attributes of the
              inner <div> are moved to the outer one. As well, nested <div> with ID attributes are  not  merged.
              If set to "yes", the attributes of the inner <div> are discarded with the exception of "class" and
              "style".

                                                                                    See also: clean, merge-spans

       merge-spans

              Type:    AutoBool
              Default: auto
              Example: auto, y/n, yes/no, t/f, true/false, 1/0

              Can be used to modify behavior of -c (--clean yes) option. This option specifies  if  Tidy  should
              merge nested <span> such as "<span><span>...</span></span>". The algorithm is identical to the one
              used by --merge-divs.

                                                                                     See also: clean, merge-divs

       ncr

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should allow numeric character references.

       new-blocklevel-tags

              Type:    Tag names
              Default: -
              Example: tagX, tagY, ...

              This option specifies new block-level tags. This option takes a space or comma separated  list  of
              tag  names.  Unless  you declare new tags, Tidy will refuse to generate a tidied file if the input
              includes previously unknown tags. Note you can't change the content model  for  elements  such  as
              <TABLE>, <UL>, <OL> and <DL>. This option is ignored in XML mode.

                                                         See also: new-empty-tags, new-inline-tags, new-pre-tags

       new-empty-tags

              Type:    Tag names
              Default: -
              Example: tagX, tagY, ...

              This  option specifies new empty inline tags. This option takes a space or comma separated list of
              tag names. Unless you declare new tags, Tidy will refuse to generate a tidied file  if  the  input
              includes  previously  unknown  tags.  Remember  to  also  declare  empty  tags as either inline or
              blocklevel. This option is ignored in XML mode.

                                                    See also: new-blocklevel-tags, new-inline-tags, new-pre-tags

       new-inline-tags

              Type:    Tag names
              Default: -
              Example: tagX, tagY, ...

              This option specifies new non-empty inline tags. This option takes a space or comma separated list
              of tag names. Unless you declare new tags, Tidy will refuse to generate a tidied file if the input
              includes previously unknown tags. This option is ignored in XML mode.

                                                     See also: new-blocklevel-tags, new-empty-tags, new-pre-tags

       new-pre-tags

              Type:    Tag names
              Default: -
              Example: tagX, tagY, ...

              This option specifies new tags that are to be processed in exactly the same way  as  HTML's  <PRE>
              element.  This  option  takes a space or comma separated list of tag names. Unless you declare new
              tags, Tidy will refuse to generate a tidied file if the input includes  previously  unknown  tags.
              Note  you  can  not as yet add new CDATA elements (similar to <SCRIPT>). This option is ignored in
              XML mode.

                                                  See also: new-blocklevel-tags, new-empty-tags, new-inline-tags

       numeric-entities

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should output entities other than the built-in HTML entities (&amp;,
              &lt;,  &gt; and &quot;) in the numeric rather than the named entity form. Only entities compatible
              with the DOCTYPE declaration generated are used. Entities that can be represented  in  the  output
              encoding are translated correspondingly.

                                                                            See also: doctype, preserve-entities

       output-html

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should generate pretty printed output, writing it as HTML.

       output-xhtml

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if  Tidy  should generate pretty printed output, writing it as extensible
              HTML. This option causes Tidy to set the DOCTYPE and default namespace as appropriate to XHTML. If
              a  DOCTYPE  or  namespace  is  given  they  will  checked  for consistency with the content of the
              document. In the case of an inconsistency, the corrected values will appear  in  the  output.  For
              XHTML,  entities  can  be  written  as  named  or numeric entities according to the setting of the
              "numeric-entities" option. The original case of tags and attributes will be preserved,  regardless
              of other options.

       output-xml

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if  Tidy  should  pretty print output, writing it as well-formed XML. Any
              entities not defined in XML 1.0 will be written as numeric entities to allow them to be parsed  by
              a  XML  parser.  The  original  case of tags and attributes will be preserved, regardless of other
              options.

       preserve-entities

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should preserve the well-formed entitites as found in the input.

       quote-ampersand

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should output unadorned & characters as &amp;.

       quote-marks

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should output " characters as &quot; as is preferred by some editing
              environments. The apostrophe character ' is written out as &#39; since many web browsers don't yet
              support &apos;.

       quote-nbsp

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should output non-breaking space characters as entities, rather than
              as the Unicode character value 160 (decimal).

       repeated-attributes

              Type:    enum
              Default: keep-last
              Example: keep-first, keep-last

              This  option  specifies  if  Tidy  should  keep  the  first  or last attribute, if an attribute is
              repeated, e.g. has two align attributes.

                                                                             See also: join-classes, join-styles

       replace-color

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should replace numeric values  in  color  attributes  by  HTML/XHTML
              color names where defined, e.g. replace "#ffffff" with "white".

       show-body-only

              Type:    AutoBool
              Default: no
              Example: auto, y/n, yes/no, t/f, true/false, 1/0

              This  option specifies if Tidy should print only the contents of the body tag as an HTML fragment.
              If set to "auto", this  is  performed  only  if  the  body  tag  has  been  inferred.  Useful  for
              incorporating  existing whole pages as a portion of another page. This option has no effect if XML
              output is requested.

       uppercase-attributes

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should output attribute names in upper  case.  The  default  is  no,
              which  results  in  lower  case  attribute names, except for XML input, where the original case is
              preserved.

       uppercase-tags

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should output tag names in upper case.  The  default  is  no,  which
              results in lower case tag names, except for XML input, where the original case is preserved.

       word-2000

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if  Tidy  should  go  to  great  pains to strip out all the surplus stuff
              Microsoft Word 2000 inserts when you save Word documents as "Web pages". Doesn't  handle  embedded
              images or VML. You should consider using Word's "Save As: Web Page, Filtered".

   Diagnostics options:
       accessibility-check

              Type:    enum
              Default: 0 (Tidy Classic)
              Example: 0 (Tidy Classic), 1 (Priority 1 Checks), 2 (Priority 2 Checks), 3 (Priority 3 Checks)

              This  option  specifies what level of accessibility checking, if any, that Tidy should do. Level 0
              is  equivalent  to  Tidy  Classic's  accessibility  checking.  For  more  information  on   Tidy's
              accessibility checking, visit the Adaptive Technology Resource Centre at the University of Toronto
              at http://www.aprompt.ca/Tidy/accessibilitychecks.html.

       show-errors

              Type:    Integer
              Default: 6
              Example: 0, 1, 2, ...

              This option specifies the number Tidy uses to determine if further errors should be shown. If  set
              to 0, then no errors are shown.

       show-warnings

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies if Tidy should suppress warnings. This can be useful when a few errors are
              hidden in a flurry of warnings.

   Pretty Print options:
       break-before-br

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should output a line break before each <BR> element.

       indent

              Type:    AutoBool
              Default: no
              Example: auto, y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should indent block-level tags. If set to "auto", this option causes
              Tidy to decide whether or not to indent the content of tags such as TITLE, H1-H6, LI, TD, TD, or P
              depending on whether or not the content includes a block-level element. You are advised  to  avoid
              setting indent to yes as this can expose layout bugs in some browsers.

                                                                                         See also: indent-spaces

       indent-attributes

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should begin each attribute on a new line.

       indent-spaces

              Type:    Integer
              Default: 2
              Example: 0, 1, 2, ...

              This  option  specifies  the  number  of  spaces  Tidy uses to indent content, when indentation is
              enabled.

                                                                                                See also: indent

       markup

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should generate a pretty printed version of the  markup.  Note  that
              Tidy won't generate a pretty printed version if it finds significant errors (see force-output).

       punctuation-wrap

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if  Tidy  should  line  wrap  after  some  Unicode or Chinese punctuation
              characters.

       sort-attributes

              Type:    enum
              Default: none
              Example: none, alpha

              This option specifies that tidy should sort attributes within an element using the specified  sort
              algorithm. If set to "alpha", the algorithm is an ascending alphabetic sort.

       split

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              Currently not used. Tidy Classic only.

       tab-size

              Type:    Integer
              Default: 8
              Example: 0, 1, 2, ...

              This  option  specifies  the  number of columns that Tidy uses between successive tab stops. It is
              used to map tabs to spaces when reading the input. Tidy never outputs tabs.

       vertical-space

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should add some empty lines for readability.

       wrap

              Type:    Integer
              Default: 68
              Example: 0 (no wrapping), 1, 2, ...

              This option specifies the right margin Tidy uses for line wrapping. Tidy tries to  wrap  lines  so
              that they do not exceed this length. Set wrap to zero if you want to disable line wrapping.

       wrap-asp

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if Tidy should line wrap text contained within ASP pseudo elements, which
              look like: <% ... %>.

       wrap-attributes

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should line wrap attribute values, for easier editing.  This  option
              can be set independently of wrap-script-literals.

                                                                                  See also: wrap-script-literals

       wrap-jste

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies if Tidy should line wrap text contained within JSTE pseudo elements, which
              look like: <# ... #>.

       wrap-php

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should line wrap text contained within PHP  pseudo  elements,  which
              look like: <?php ... ?>.

       wrap-script-literals

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies if Tidy should line wrap string literals that appear in script attributes.
              Tidy wraps long script string literals by inserting a backslash character before the line break.

                                                                                       See also: wrap-attributes

       wrap-sections

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should line wrap text contained within <![ ... ]> section tags.

   Character Encoding options:
       ascii-chars

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              Can be used to modify behavior of -c (--clean  yes)  option.  If  set  to  "yes"  when  using  -c,
              &emdash;,  &rdquo;,  and  other  named  character  entities  are downgraded to their closest ascii
              equivalents.

                                                                                                 See also: clean

       char-encoding

              Type:    Encoding
              Default: ascii
              Example: raw, ascii, latin0, latin1, utf8, iso2022, mac, win1252, ibm858, utf16le, utf16be, utf16,
              big5, shiftjis

              This  option  specifies the character encoding Tidy uses for both the input and output. For ascii,
              Tidy will accept Latin-1 (ISO-8859-1) character values, but will use entities for  all  characters
              whose  value  >  127.  For  raw,  Tidy  will output values above 127 without translating them into
              entities. For latin1, characters above 255 will be written as entities.  For  utf8,  Tidy  assumes
              that  both  input  and output is encoded as UTF-8. You can use iso2022 for files encoded using the
              ISO-2022 family of encodings e.g. ISO-2022-JP. For  mac  and  win1252,  Tidy  will  accept  vendor
              specific  character  values,  but  will  use  entities  for  all characters whose value > 127. For
              unsupported encodings, use an external utility to convert to and from UTF-8.

                                                                       See also: input-encoding, output-encoding

       input-encoding

              Type:    Encoding
              Default: latin1
              Example: raw, ascii, latin0, latin1, utf8, iso2022, mac, win1252, ibm858, utf16le, utf16be, utf16,
              big5, shiftjis

              This  option  specifies the character encoding Tidy uses for the input. See char-encoding for more
              info.

                                                                                         See also: char-encoding

       language

              Type:    String
              Default: -
              Default: -

              Currently not used, but this option specifies the language Tidy uses (for instance "en").

       newline

              Type:    enum
              Default: Platform dependent
              Example: LF, CRLF, CR

              The default is appropriate to the current platform: CRLF on PC-DOS, MS-Windows  and  OS/2,  CR  on
              Classic Mac OS, and LF everywhere else (Unix and Linux).

       output-bom

              Type:    AutoBool
              Default: auto
              Example: auto, y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should write a Unicode Byte Order Mark character (BOM; also known as
              Zero Width No-Break Space; has value of U+FEFF) to the beginning of the output; only for UTF-8 and
              UTF-16  output  encodings.  If set to "auto", this option causes Tidy to write a BOM to the output
              only if a BOM was present at the beginning of the input. A BOM is  always  written  for  XML/XHTML
              output using UTF-16 output encodings.

       output-encoding

              Type:    Encoding
              Default: ascii
              Example: raw, ascii, latin0, latin1, utf8, iso2022, mac, win1252, ibm858, utf16le, utf16be, utf16,
              big5, shiftjis

              This option specifies the character encoding Tidy uses for the output. See char-encoding for  more
              info.  May  only be different from input-encoding for Latin encodings (ascii, latin0, latin1, mac,
              win1252, ibm858).

                                                                                         See also: char-encoding

   Miscellaneous options:
       error-file

              Type:    String
              Default: -
              Default: -

              This option specifies the error file Tidy uses  for  errors  and  warnings.  Normally  errors  and
              warnings are output to "stderr".

                                                                                           See also: output-file

       force-output

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if  Tidy  should  produce output even if errors are encountered. Use this
              option with care - if Tidy reports an error, this means Tidy was not able to, or is not  sure  how
              to, fix the error, so the resulting output may not reflect your intention.

       gnu-emacs

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option  specifies  if  Tidy  should change the format for reporting errors and warnings to a
              format that is more easily parsed by GNU Emacs.

       gnu-emacs-file

              Type:    String
              Default: -
              Default: -

              Used internally.

       keep-time

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should keep the  original  modification  time  of  files  that  Tidy
              modifies  in  place. The default is no. Setting the option to yes allows you to tidy files without
              causing these files to be uploaded to a web server when using a tool such as SiteCopy.  Note  this
              feature is not supported on some platforms.

       output-file

              Type:    String
              Default: -
              Default: -

              This  option  specifies  the  output  file  Tidy  uses  for  markup. Normally markup is written to
              "stdout".

                                                                                            See also: error-file

       quiet

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should output the summary of the numbers of errors and warnings,  or
              the welcome or informational messages.

       slide-style

              Type:    String
              Default: -
              Default: -

              Currently not used. Tidy Classic only.

       tidy-mark

              Type:    Boolean
              Default: yes
              Example: y/n, yes/no, t/f, true/false, 1/0

              This  option specifies if Tidy should add a meta element to the document head to indicate that the
              document has been tidied. Tidy won't add a meta element if one is already present.

       write-back

              Type:    Boolean
              Default: no
              Example: y/n, yes/no, t/f, true/false, 1/0

              This option specifies if Tidy should write back the tidied markup to the same file it  read  from.
              You  are  advised  to keep copies of important files before tidying them, as on rare occasions the
              result may not be what you expect.
