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 stan-
dard 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.

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 documenta-
tion, 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 direc-
tories. 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 cate-
gories: 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 struc-
tural 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 ele-
ment.
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 (&, <, > and ") 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 &.
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 " as is preferred by some editing environments. The apostrophe
character ' is written out as ' since many web browsers don't yet support '.
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 per-
formed 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, Fil-
tered".
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 read-
ing 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 lit-
erals 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;, ”, and other named charac-
ter 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.

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.

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).

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 inten-
tion.
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 mes-
sages.
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.
