Description

TIDY(1)                              5.4.0                             TIDY(1)



NAME
       tidy - check, correct, and pretty-print HTML(5) files

SYNOPSIS
       tidy [options] [file ...] [options] [file ...] ...

DESCRIPTION
       Tidy reads HTML, XHTML, and XML files and writes cleaned-up markup.
       For HTML variants, it detects, reports, and corrects many common coding
       errors and strives to produce visually equivalent markup that is both
       conformant to the HTML specifications and that works in 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.

OPTIONS
       Tidy supports two different kinds of options.  Purely command-line
       options, starting with a single dash '-', can only be used on the
       command-line, not in configuration files.  They are listed in the first
       part of this section.  Configuration options, on the other hand, can
       either be passed on the command line, starting with two dashes --, or
       specified in a configuration file, using the option name without the
       starting dashes.  They are listed in the second part of this section.

       For command-line options that expect a numerical argument, a default is
       assumed if no meaningful value can be found.  On the other hand,
       configuration options cannot be used without a value; a configuration
       option without a value is simply discarded and reported as an error.

       Using a command-line option is sometimes equivalent to setting the
       value of a configuration option.  The equivalent option and value are
       shown in parentheses in the list below, as they would appear in a
       configuration file.  For example, -quiet, -q (quiet: yes) means that
       using the command-line option -quiet or -q is equivalent to setting the
       configuration option quiet to yes.

       Single-letter command-line options without an associated value can be
       combined; for example '-i', '-m' and '-u' may be combined as '-imu'.

   File manipulation
       -output <%s>, -o <%s> (output-file: <%s>)
              write output to the specified <file>

       -config <%s>
              set configuration options from the specified <file>

       -file <%s>, -f <%s> (error-file: <%s>)
              write errors and warnings to the specified <file>

              wrap text at the specified <column>. 0 is assumed if <column> is
              missing. When this option is omitted, the default of the
              configuration option 'wrap' applies.

       -access <%s> (accessibility-check: <%s>)
              do additional accessibility checks (<level> = 0, 1, 2, 3). 0 is
              assumed if <level> is missing.

       -help-config
              list all configuration options

       -show-config
              list the current configuration settings

       -help-option <%s>
              show a description of the <option>

       -language <%s> (language: <%s>)
              set Tidy's output language to <lang>. Specify '-language help'
              for more help. Use before output-causing arguments to ensure the
              language takes effect, e.g.,`tidy -lang es -lang help`.

   XML
       -xml-help
              list the command line options in XML format

       -xml-config
              list all configuration options in XML format

       -xml-strings
              output all of Tidy's strings in XML format

       -xml-error-strings
              output error constants and strings in XML format

       -xml-options-strings
              output option descriptions in XML format

       Configuration options can 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 option:

          tidy --option1 value1 --option2 value2 ...
          tidy -config config-file  ...

       Configuration options can be conveniently grouped in a single config
       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,
       which are listed in the Supported values sections below.

       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.

   HTML, XHTML, XML options

       --add-xml-decl Boolean (no if unset)
              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, then the declaration is always added
              as required by the XML standard.

              See also: --char-encoding, --output-encoding

       --add-xml-space Boolean (no if unset)
              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 String
              This option specifies the default alt= text Tidy uses for <img>
              attributes when the alt= attribute is missing.

              Use with care, as it is your responsibility to make your
              documents accessible to people who cannot see the images.

       --anchor-as-name Boolean (yes if unset)
              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 Boolean (no if unset)
              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 Boolean (no if unset)
              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 Boolean (no if unset)
              This option specifies if Tidy should perform cleaning of some
              legacy presentational tags (currently <i>, <b>, <center> when
              enclosed within appropriate inline tags, and <font>). If set to
              yes then legacy tags will be replaced with CSS <style> tags and
              structural markup as appropriate.

       --coerce-endtags Boolean (yes if unset)
              This option specifies if Tidy should coerce a start tag into an
              end tag in cases where it looks like an end tag was probably
              intended; for example, given

              <span>foo <b>bar<b> baz</span>

              Tidy will output

              <span>foo <b>bar</b> baz</span>

       --css-prefix String
              This option specifies the prefix that Tidy uses for styles
              rules.

              By default, c will be used.

       --decorate-inferred-ul Boolean (no if unset)
              This option specifies if Tidy should decorate inferred <ul>
              elements with some CSS markup to avoid indentation to the right.

       --doctype DocType (auto if unset)
              Supported values: html5, 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.
              Note this this also implies numeric-entities is set to yes.

              If set to html5 the DOCTYPE is set to <!DOCTYPE html>.

              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 HTML4 or
              XHTML1 strict DTD.

              If set to loose, the DOCTYPE is set to the HTML4 or XHTML1 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.

              This option does not offer a validation of document conformance.

       --drop-empty-elements Boolean (yes if unset)
              This option specifies if Tidy should discard empty elements.

       --drop-empty-paras Boolean (yes if unset)
              This option specifies if Tidy should discard empty paragraphs.

       --drop-font-tags Boolean (no if unset)
              Deprecated; do not use. This option is destructive to <font>
              tags, and it will be removed from future versions of Tidy. Use
              the clean option instead.

              If you do set this option despite the warning it will perform as
              clean except styles will be inline instead of put into a CSS
              class. <font> tags will be dropped completely and their styles
              will not be preserved.

              If both clean and this option are enabled, <font> tags will
              still be dropped completely, and other styles will be preserved
              in a CSS class instead of inline.

              See clean for more information.

       --drop-proprietary-attributes Boolean (no if unset)
              This option specifies if Tidy should strip out proprietary
              attributes, such as Microsoft data binding attributes.
              Additionally attributes that aren't permitted in the output
              version of HTML will be dropped if used with strict-tags-
              attributes.

       --enclose-block-text Boolean (no if unset)
              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 Boolean (no if unset)
              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 Boolean (no if unset)
              This option specifies if Tidy should convert <![CDATA[]]>
              sections to normal text.

       --fix-backslash Boolean (yes if unset)
              This option specifies if Tidy should replace backslash
              characters \ in URLs with forward slashes /.

       --fix-bad-comments Boolean (yes if unset)
              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 Boolean (yes if unset)
              This option specifies if Tidy should check attribute values that
              carry URIs for illegal characters and if such are found, escape
              them as HTML4 recommends.

       --gdoc Boolean (no if unset)
              This option specifies if Tidy should enable specific behavior
              for cleaning up HTML exported from Google Docs.

       --hide-comments Boolean (no if unset)
              This option specifies if Tidy should print out comments.

       --hide-endtags Boolean (no if unset)
              This option is an alias for omit-optional-tags.

       --indent-cdata Boolean (no if unset)
              This option specifies if Tidy should indent <![CDATA[]]>
              sections.

       --input-xml Boolean (no if unset)
              This option specifies if Tidy should use the XML parser rather
              than the error correcting HTML parser.

       --join-classes Boolean (no if unset)
              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.

       --join-styles Boolean (yes if unset)
              This option specifies if Tidy should combine styles to generate
              a single, new style if multiple style values are detected on an
              element.

       --literal-attributes Boolean (no if unset)
              This option specifies how Tidy deals with whitespace characters
              within attribute values.

              If the value is no Tidy normalizes attribute values by replacing
              any newline or tab with a single space, and further by replacing
              any contiguous whitespace with a single space.

              To force Tidy to preserve the original, literal values of all
              attributes and ensure that whitespace within attribute values is
              passed through unchanged, set this option to yes.

       --logical-emphasis Boolean (no if unset)
              This option specifies if Tidy should replace any occurrence of
              <i> with <em> and any occurrence of <b> with <strong>. Any
              attributes are preserved unchanged.

              This option can be set independently of the clean option.

       --lower-literals Boolean (yes if unset)
              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 AutoBool (auto if unset)
              This option can be used to modify the behavior of clean when set
              to yes.

              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. 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-emphasis Boolean (yes if unset)
              This option specifies if Tidy should merge nested <b> and <i>
              elements; for example, for the case

              <b class="rtop-2">foo <b class="r2-2">bar</b> baz</b>,

              Tidy will output <b class="rtop-2">foo bar baz</b>.

       --merge-spans AutoBool (auto if unset)
              This option can be used to modify the behavior of clean when set
              to yes.

              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 Boolean (yes if unset)
              This option specifies if Tidy should allow numeric character
              references.

       --new-blocklevel-tags Tag names
              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 Tag names
              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 Tag names
              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 Tag names
              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 cannot as yet add new CDATA elements.

              This option is ignored in XML mode.

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

       --numeric-entities Boolean (no if unset)
              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

       --omit-optional-tags Boolean (no if unset)
              This option specifies if Tidy should omit optional start tags
              and end tags when generating output.

              Setting this option causes all tags for the <html>, <head>, and
              <body> elements to be omitted from output, as well as such end
              tags as </p>, </li>, </dt>, </dd>, </option>, </tr>, </td>, and
              </th>.

              This option is ignored for XML output.

       --output-html Boolean (no if unset)
              This option specifies if Tidy should generate pretty printed
              output, writing it as HTML.

       --output-xhtml Boolean (no if unset)
              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, and will use the corrected value in
              output regardless of other sources.

              For XHTML, entities can be written as named or numeric entities
              according to the setting of numeric-entities.

              The original case of tags and attributes will be preserved,
              regardless of other options.

       --output-xml Boolean (no if unset)
              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 an XML parser.

              The original case of tags and attributes will be preserved,
              regardless of other options.

       --preserve-entities Boolean (no if unset)
              This option specifies if Tidy should preserve well-formed
              entities as found in the input.

       --quote-ampersand Boolean (yes if unset)
              This option specifies if Tidy should output unadorned &
              characters as &amp;.

       --quote-marks Boolean (no if unset)
              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 Boolean (yes if unset)
              This option specifies if Tidy should output non-breaking space
              characters as entities, rather than as the Unicode character
              value 160 (decimal).

       --repeated-attributes enum (keep-last if unset)
              Supported values: 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 Boolean (no if unset)
              This option specifies if Tidy should replace numeric values in
              color attributes with HTML/XHTML color names where defined, e.g.
              replace #ffffff with white.

       --show-body-only AutoBool (no if unset)
              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.

       --skip-nested Boolean (yes if unset)
              This option specifies that Tidy should skip nested tags when
              parsing script and style data.

       --strict-tags-attributes Boolean (no if unset)
              This options ensures that tags and attributes are applicable for
              the version of HTML that Tidy outputs. When set to yes (the
              default) and the output document type is a strict doctype, then
              Tidy will report errors. If the output document type is a loose
              or transitional doctype, then Tidy will report warnings.

              Additionally if drop-proprietary-attributes is enabled, then not
              applicable attributes will be dropped, too.

              When set to no, these checks are not performed.

       --uppercase-attributes Boolean (no if unset)
              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 Boolean (no if unset)
              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 Boolean (no if unset)
              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". It doesn't handle embedded
              images or VML.

              You should consider using Word's "Save As: Web Page, Filtered".

   Diagnostics options

       --accessibility-check enum (0 (Tidy Classic) if unset)
              Supported values: 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 perform.

              Level 0 (Tidy Classic) is equivalent to Tidy Classic's
              accessibility checking.

              For more information on Tidy's accessibility checking, visit
              Tidy's Accessibility Page at http://www.html-
              tidy.org/accessibility/.

       --show-errors Integer (6 if unset)
              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-info Boolean (yes if unset)
              This option specifies if Tidy should display info-level
              messages.

       --show-warnings Boolean (yes if unset)
              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 Boolean (no if unset)
              This option specifies if Tidy should output a line break before
              each <br> element.

       --escape-scripts Boolean (yes if unset)
              This option causes items that look like closing tags, like </g
              to be escaped to <\/g. Set this option to 'no' if you do not
              want this.

       --indent AutoBool (no if unset)
              This option specifies if Tidy should indent block-level tags.

              If set to auto Tidy will decide whether or not to indent the
              content of tags such as <title>, <h1>-<h6>, <li>, <td>, or <p>
              based on the content including a block-level element.

              Setting indent to yes can expose layout bugs in some browsers.

              Use the option indent-spaces to control the number of spaces or
              tabs output per level of indent, and indent-with-tabs to specify
              whether spaces or tabs are used.

              See also: --indent-spaces

       --indent-attributes Boolean (no if unset)
              This option specifies if Tidy should begin each attribute on a
              new line.

       --indent-spaces Integer (2 if unset)
              This option specifies the number of spaces or tabs that Tidy
              uses to indent content when indent is enabled.

              Note that the default value for this option is dependent upon
              the value of indent-with-tabs (see also).

              See also: --indent

       --indent-with-tabs Boolean (no if unset)
              This option specifies if Tidy should indent with tabs instead of
              spaces, assuming indent is yes.

              Set it to yes to indent using tabs instead of the default
              spaces.

              Use the option indent-spaces to control the number of tabs
              output per level of indent. Note that when indent-with-tabs is
              enabled the default value of indent-spaces is reset to 1.

              Note tab-size controls converting input tabs to spaces. Set it
              to zero to retain input tabs.

       --markup Boolean (yes if unset)
              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 Boolean (no if unset)
              This option specifies if Tidy should line wrap after some
              Unicode or Chinese punctuation characters.

       --sort-attributes enum (none if unset)
              Supported values: 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 Boolean (no if unset)
              This option has no function and is deprecated.

       --tab-size Integer (8 if unset)
              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.

       --vertical-space AutoBool (no if unset)
              This option specifies if Tidy should add some extra empty lines
              for readability.

              The default is no.

              If set to auto Tidy will eliminate nearly all newline
              characters.

       --wrap Integer (68 if unset)
              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 0(zero) if you want to disable line wrapping.

       --wrap-asp Boolean (yes if unset)
              This option specifies if Tidy should line wrap text contained
              within ASP pseudo elements, which look like: <% ... %>.

       --wrap-attributes Boolean (no if unset)
              This option specifies if Tidy should line-wrap attribute values,
              meaning that if the value of an attribute causes a line to
              exceed the width specified by wrap, Tidy will add one or more
              line breaks to the value, causing it to be wrapped into multiple
              lines.

              Note that this option can be set independently of wrap-script-
              literals. By default Tidy replaces any newline or tab with a
              single space and replaces any sequences of whitespace with a
              single space.

              To force Tidy to preserve the original, literal values of all
              attributes, and ensure that whitespace characters within
              attribute values are passed through unchanged, set literal-
              attributes to yes.

              See also: --wrap-script-literals, --literal-attributes

       --wrap-jste Boolean (yes if unset)
              This option specifies if Tidy should line wrap text contained
              within JSTE pseudo elements, which look like: <# ... #>.

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

       --wrap-script-literals Boolean (no if unset)
              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 Boolean (yes if unset)
              This option specifies if Tidy should line wrap text contained
              within <![ ... ]> section tags.

   Character Encoding options

       --ascii-chars Boolean (no if unset)
              Can be used to modify behavior of the clean option when set to
              yes.

              If set to yes when using clean, &emdash;, &rdquo;, and other
              named character entities are downgraded to their closest ASCII
              equivalents.

              See also: --clean

       --char-encoding Encoding (utf8 if unset)
              Supported values: 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 are 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 Encoding (utf8 if unset)
              Supported values: 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 String
              Currently not used, but this option specifies the language Tidy
              would use if it were properly localized. For example: en.

       --newline enum (Platform dependent if unset)
              Supported values: LF, CRLF, CR

              The default is appropriate to the current platform.

              Genrally CRLF on PC-DOS, Windows and OS/2; CR on Classic Mac OS;
              and LF everywhere else (Linux, Mac OS X, and Unix).

       --output-bom AutoBool (auto if unset)
              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, and only
              applies to 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 Encoding (utf8 if unset)
              Supported values: 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.

              Note that this may only be different from input-encoding for
              Latin encodings (ascii, latin0, latin1, mac, win1252, ibm858).

              See char-encoding for more information

              See also: --char-encoding

   Miscellaneous options

       --error-file String
              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 Boolean (no if unset)
              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 Boolean (no if unset)
              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 String
              Used internally.

       --keep-time Boolean (no if unset)
              This option specifies if Tidy should keep the original
              modification time of files that Tidy modifies in place.

              Setting the option to yes allows you to tidy files without
              changing the file modification date, which may be useful with
              certain tools that use the modification date for things such as
              automatic server deployment.

              Note this feature is not supported on some platforms.

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

              See also: --error-file

       --quiet Boolean (no if unset)
              This option specifies if Tidy should output the summary of the
              numbers of errors and warnings, or the welcome or informational
              messages.

       --slide-style String
              This option has no function and is deprecated.

       --tidy-mark Boolean (yes if unset)
              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 Boolean (no if unset)
              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.

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.
