gnu-emacs |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
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. | ||
markup |
Top | |
Type: | Boolean | |
Default: | yes | |
Example: | no, yes | |
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 ). |
||
mute |
Top | |
Type: | String | |
Default: | - | |
Example: | - | |
See Also: | mute-id | |
Use this option to prevent Tidy from displaying certain types of report output, for example, for conditions that you wish to ignore. This option takes a list of one or more keys indicating the message type to mute. You can discover these message keys by using the mute-id configuration option and examining Tidy's output. |
||
mute-id |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
See Also: | mute | |
This option indicates whether or not Tidy should display message ID's with each of its error reports. This could be useful if you wanted to use the mute configuration option in order to filter out certain report messages. |
||
quiet |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
When enabled, this option limits Tidy's non-document output to report only document warnings and errors. | ||
show-body-only |
Top | |
Type: | Enum | |
Default: | no | |
Example: | no, yes, auto | |
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. |
||
show-errors |
Top | |
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-info |
Top | |
Type: | Boolean | |
Default: | yes | |
Example: | no, yes | |
This option specifies if Tidy should display info-level messages. | ||
show-warnings |
Top | |
Type: | Boolean | |
Default: | yes | |
Example: | no, yes | |
This option specifies if Tidy should suppress warnings. This can be useful when a few errors are hidden in a flurry of warnings. | ||
Document In and Out |
||
add-meta-charset |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
This option, when enabled, adds a <meta> element and sets the charset attribute to the encoding of the document. Set this option to yes to enable it. |
||
add-xml-decl |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
See Also: | char-encoding, output-encoding | |
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. |
||
add-xml-space |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
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. |
||
doctype |
Top | |
Type: | String | |
Default: | auto | |
Example: | - | |
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. Note that selecting this option will not change the current document's DOCTYPE on output. 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. |
||
input-xml |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
This option specifies if Tidy should use the XML parser rather than the error correcting HTML parser. | ||
output-html |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
This option specifies if Tidy should generate pretty printed output, writing it as HTML. | ||
output-xhtml |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
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 |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
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. |
||
File Input-Output |
||
error-file |
Top | |
Type: | String | |
Default: | - | |
Example: | - | |
See Also: | output-file | |
This option specifies the error file Tidy uses for errors and warnings. Normally errors and warnings are output to stderr . |
||
keep-time |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
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 |
Top | |
Type: | String | |
Default: | - | |
Example: | - | |
See Also: | error-file | |
This option specifies the output file Tidy uses for markup. Normally markup is written to stdout . |
||
write-back |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
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. |
||
Diagnostics |
||
accessibility-check |
Top | |
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 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. |
||
force-output |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
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. |
||
show-meta-change |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
This option enables a message whenever Tidy changes the content attribute of a meta charset declaration to match the encoding of the document. Set this option to yes to enable it. |
||
warn-proprietary-attributes |
Top | |
Type: | Boolean | |
Default: | yes | |
Example: | no, yes | |
This option specifies if Tidy should warn on proprietary attributes. | ||
Encoding |
||
char-encoding |
Top | |
Type: | Encoding | |
Default: | utf8 | |
Example: | raw, ascii, latin0, latin1, utf8, iso2022, mac, win1252, ibm858, utf16le, utf16be, utf16, big5, shiftjis | |
See Also: | input-encoding, output-encoding | |
This option specifies the character encoding Tidy uses for input, and when set, automatically chooses an appropriate character encoding to be used for output. The output encoding Tidy chooses may be different from the input encoding. For ascii, latin0, ibm858, mac, and win1252 input encodings, the output-encoding option will automatically be set to ascii. You can set output-encoding manually to override this. For other input encodings, the output-encoding option will automatically be set to the the same value. Regardless of the preset value, you can set output-encoding manually to override this. Tidy is not an encoding converter. Although the Latin and UTF encodings can be mixed freely, it is not possible to convert Asian encodings to Latin encodings with Tidy. |
||
input-encoding |
Top | |
Type: | Encoding | |
Default: | utf8 | |
Example: | raw, ascii, latin0, latin1, utf8, iso2022, mac, win1252, ibm858, utf16le, utf16be, utf16, big5, shiftjis | |
See Also: | char-encoding | |
This option specifies the character encoding Tidy uses for input. Tidy makes certain assumptions about some of the input encodings. For ascii, Tidy will accept Latin-1 (ISO-8859-1) character values and convert them to entities as necessary. For raw, Tidy will make no assumptions about the character values and will pass them unchanged to output. For mac and win1252, vendor specific characters values will be accepted and converted to entities as necessary. Asian encodings such as iso2022 will be handled appropriately assuming the corresponding output-encoding is also specified. Tidy is not an encoding converter. Although the Latin and UTF encodings can be mixed freely, it is not possible to convert Asian encodings to Latin encodings with Tidy. |
||
newline |
Top | |
Type: | Enum | |
Default: | LF | |
Example: | 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, macOS, and Unix). |
||
output-bom |
Top | |
Type: | Enum | |
Default: | auto | |
Example: | no, yes, auto | |
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 |
Top | |
Type: | Encoding | |
Default: | utf8 | |
Example: | raw, ascii, latin0, latin1, utf8, iso2022, mac, win1252, ibm858, utf16le, utf16be, utf16, big5, shiftjis | |
See Also: | char-encoding | |
This option specifies the character encoding Tidy uses for output. Some of the output encodings affect whether or not some characters are translated to entities, although in all cases, some entities will be written according to other Tidy configuration options. For ascii, mac, and win1252 output encodings, entities will be used for all characters with values over 127. For raw output, Tidy will write values above 127 without translating them to entities. Output using latin1 will cause Tidy to write character values higher than 255 as entities. The UTF family such as utf8 will write output in the respective UTF encoding. Asian output encodings such as iso2022 will write output in the specified encoding, assuming a corresponding input-encoding was specified. Tidy is not an encoding converter. Although the Latin and UTF encodings can be mixed freely, it is not possible to convert Asian encodings to Latin encodings with Tidy. |
||
Cleanup |
||
bare |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
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. | ||

||
merge-divs |
Top | |
Type: | Enum | |
Default: | auto | |
Example: | no, yes, auto | |
See Also: | clean, merge-spans | |
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 . |
||
merge-spans |
Top | |
Type: | Enum | |
Default: | auto | |
Example: | no, yes, auto | |

||
anchor-as-name |
Top | |
Type: | Boolean | |
Default: | yes | |
Example: | no, yes | |
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 |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
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. |
||
coerce-endtags |
Top | |
Type: | Boolean | |
Default: | yes | |
Example: | no, yes | |
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 |
Top | |
Type: | String | |
Default: | c | |
Example: | - | |
This option specifies the prefix that Tidy uses for styles rules. By default, c will be used. |
||
custom-tags |
Top | |
Type: | Enum | |
Default: | no | |
Example: | no, blocklevel, empty, inline, pre | |
See Also: | new-blocklevel-tags, new-empty-tags, new-inline-tags, new-pre-tags | |
This option enables the use of tags for autonomous custom elements, e.g. <flag-icon> with Tidy. Custom tags are disabled if this value is no. Other settings - blocklevel, empty, inline, and pre will treat all detected custom tags accordingly. The use of new-blocklevel-tags , new-empty-tags , new-inline-tags , or new-pre-tags will override the treatment of custom tags by this configuration option. This may be useful if you have different types of custom tags.When enabled these tags are determined during the processing of your document using opening tags; matching closing tags will be recognized accordingly, and unknown closing tags will be discarded. |
||
enclose-block-text |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |

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. |
||
lower-literals |
Top | |
Type: | Boolean | |
Default: | yes | |
Example: | no, yes | |
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. |

Example: | no, yes | |
This option specifies that Tidy should skip nested tags when parsing script and style data. | ||
strict-tags-attributes |
Top | |
Type: | Boolean | |
Default: | no | |
Example: | no, yes | |
This options ensures that tags and attributes are applicable for the version of HTML that Tidy outputs. When set to yes 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.
