Use HTML Tidy to just indent HTML code?
You need the following option:
tidy --show-body-only yes -i 4 -w 80 -m file.html
http://tidy.sourceforge.net/docs/quickref.html#show-body-only
-i 4
- indents 4 spaces (EDIT: tidy never uses tabs)
or--indent-with-tabs yes
- instead (--tab-size
may affect wrapping)
-w 80
- wrap at column 80 (default on my system: 68, very narrow)
-m
- modify file inplace
(you may want to leave out the last option, and examine the output first)
Showing only body, will naturally leave out the tidy-mark
(generator meta
).
Another cool options are:
--quiet yes
- doesn't print W3C advertisements and other unnecessary output
(errors still reported)
I didn't found a possibility "only reindent - without any changes". The next config file will "repair" as low as possible and (mostly) only re-indent the html. Tidy
still correcting some errorish conditions, like duplicated (repeated) attributes.

For example the next html-fragment
<div>
<div>
<p>
not closed para
<h1>
h1 head
</h1>
<ul>
<li>not closed li
<li>closed li</li>
</ul>
some text
</div>
</div>
will changed to
<div>
<div>
<p>
not closed para
<h1>
h1 head
</h1>
<ul>
<li>not closed li
<li>closed li
</ul>some text
</div>
</div>
As you can notice, the hide-endtags: yes
hides the closing </li>
from the second bullet in the input. Setting the hide-endtags: no
- will get the next:
<div>
<div>
<p>
not closed para
</p>
<h1>
h1 head
</h1>
<ul>
<li>not closed li
</li>
<li>closed li
</li>
</ul>some text
</div>
</div>
so, tidy
adds closing </p>
and closing </li>
to first bullet.
I didn't found a possibility preserve everything on input and only reindent the file.
Use the indent
, tidy-mark
, and quiet
options:
tidy \
-indent \
--indent-spaces 2 \
-quiet \
--tidy-mark no \
index.html
Or, using a config file rather than command-line options:
indent: auto
indent-spaces: 2
quiet: yes
tidy-mark: no
Name it tidy_config.txt
and save it the same directory as the .html file. Run it like this:
tidy -config tidy_config.txt index.html
For more customization, use the tidy man page to find other relevant options such as markup: no
or force-output: yes
.
