TIDY(1) 4.9.36 TIDY(1)NAME
tidy - check, correct, and pretty-print HTML(5) files
SYNOPSIS
tidy [option ...] [file ...] [option ...] [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. For command line options that expect a numerical
argument, a default is assumed if no meaningful value can be found.

Processing directives
-indent, -i

Miscellaneous
-version, -v
show the version of Tidy
-help, -h, -?
list the command line options
-xml-help
list the command line options in XML format
-help-config
list all configuration options
-xml-config
list all configuration options in XML format
-show-config
list the current configuration settings
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
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.
