<a name="Introduction"></a>
<h2>Introduction</h2>
w3m is a pager/text-based WWW browser. You can browse local documents and/or
documents on the WWW using a terminal emulator.
<hr>
<a name="Options"></a>
<h2>Options</h2>
Command line usage is
<p>
<pre>
w3m [options] [file|URL]
</pre>
<P>
If you specify filenames/URLs on command line, these documents are displayed.
If you specify nothing, w3m reads a document from standard input and display it.
If no filename and/or URLs are specified and standard input is tty, w3m terminates
without displaying anything.
<p>
Options are as follows:
<dl>
<dt>+<line number>
<dd>Move to the specified line.
<dt>-t width
<dd>Specify tab width. Default is 8.
<dt>-r
<dd>When displaying text/plain document, prohibit emphasis using backspace.
If you don't specify this option,
``A^H_'' is interpreted as underlined character and ``A^HA'' as a bold character.
<dt>-S
<dd>When displaying text/plain document, squeeze blank lines.
<dt>-l number
<dd>Specify line number preserved internally when reading text/plain document
fron standard input. Default is 10000.
<dt>-s
<dd>Display documents with Shift_JIS code.
<dt>-e
<dd>Display documents with EUC_JP code.
<dt>-j
<dd>Display documents with ISO-2022-JP code.
<dt>-T type
<dd>Specify document type. Without this option, document type
is determined from extension of a file. If the determination
fails, the document is regarded as text/plain.
<p>
Example:<br>
Read HTML document from standard input and display it
<pre>
cat hoge.html | w3m -T text/html
</pre>
<p>
Display HTML source
<pre>
w3m -T text/plain hoge.html
</pre>
<dt>-m
<dd>Display document with Internet message mode.
With this option, w3m determines document type from header infomation.
It is useful when reading E-mail or NetNews messages.
<dt>-B
<dd>Show the bookmark.
<dt>-bookmark file
<dd>Specify bookmark file.
<dt>-M
<dd>Monochrome display mode.
<dt>-F
<dd>Automatically render frame.
<dt>-S
<dd>Sqeeze blank lines.
<dt>-X
<dd>Upon exit, do not display preserved screen.
<dt>-W
<dd>Toggle wrap search mode.
<dt>-o option=value
<dd>Specify option. The option names and values are
same as that appears in ~/.w3m/config.
<dt>-cookie
<dd>Process cookies.
<dt>-no-cookie
<dd>Don't process cookies.
<dt>-pauth username:password
<dd>Set username and password for (basic) proxy authentication.
<dt>-num
<dd>Show linenumber.
<dt>-dump
<dd>Read document specified by URL and dump formatted text into standard
output. The width of the document become 80. This width can be overridden
with -cols option.
<dt>-cols width
<dd>Specify document width. Used with -dump option.
<dt>-ppc count
<dd> Specify the number of pixels per character (default 8.0). Larger
values will make tables narrower.
<dt>-dump_source
<dd>Read document specified by URL and dump the source.
<dt>-dump_head
<dd>Read document specified by URL and dump headers.
<dt>-no-proxy
<dd>Don't use proxy server.

<a name="Color"></a>
<h2>Document color</h2>
Links and images are displayed as follows.
<div align="center">
<table border="1">
<tr><th> </th><th>Color mode</th><th>Monochrome mode</th></tr>
<tr><td>links</td><td>blue</td><td>underline</td></tr>
<tr><td>inline images</td><td>green</td><td>reverse</td></tr>
<tr><td>form input</td><td>red</td><td>reverse</td></tr>

<h2>Key binding</h2>
After invocation, you can operate w3m by one-character commands from
the keyboard.
<P>
Here's the original key-binding table. If you are using Lynx-like key
bindings, see <a href="#Key:lynx">the Lynx-like key binding</a>.

<h2>Mouse operation</h2>
If w3m is compiled with mouse option and you are using
xterm/kterm/rxvt (in this case, you have to set the TERM
environment variable to `xterm' or `kterm'.) or GPM
environment, you can use mouse
for the navigation.
<p>
<table border=0>
<tr><td>left click
<td>Move the cursor to the place pointed by the mouse cursor.
If you click the cursor and it is on an anchor, follow the anchor.
<tr><td>middle click
<td>Back to the previous buffer.
<tr><td>right click
<td>Open pop-up menu. You can choose an item by clicking it.
<tr><td>left drag
<td>Scroll document. The default behavior is to grab the document
and drag it. You can reverse the behavior (grab the window and drag it)
with the option setting panel.
</table>
<p>
<hr>
<a name="Key:custom"></a>
<h2>Key customization</h2>
You can customize the key binding (except line-editing keymap)
by describing ~/.w3m/keymap. For example,
<pre>
keymap C-o NEXT_PAGE
</pre>
binds `NEXT_PAGE' function (normally bound to SPC and C-v)
to control-o. See <a href="README.func">README.func</a> for
list of available functions. Original and Lynx-like keymap
definitions are provided (<a href="keymap.default">keymap.default</a>
and <a href="keymap.lynx">keymap.lynx</a>) as examples.
<hr>
<a name="LocalCGI"></a>
<h2>Local CGI</h2>
You can run CGI scripts using w3m, without any HTTP server.
It means that w3m behaves like an HTTP server and activates CGI script,
then w3m reads the output of the script and display it. The
<a href="file:///$LIB/w3mbookmark?mode=panel&bmark=~/.w3m/bookmark.html&url=MANUAL.html&title=w3m+manual">bookmark registration</a>
and <a href="file:///$LIB/w3mhelperpanel?mode=panel">helper-app editor</a>
are realized as local CGI scripts.
Using local CGI, w3m can be used as a general purpose form interface.
<P>
For security reason, CGI scripts invoked by w3m must be in one of
these directories.
<ul>
<li>The directory where w3m-related files are stored
(typically /usr/local/lib/w3m). This directory can be referred
as $LIB.
<li>/cgi-bin/ directory. You can map /cgi-bin/ to any directory you like
with option setting panel (``Directory corresponds to /cgi-bin'' field).
You can specify multiple paths separated by `:', like
/usr/local/cgi-bin:/home/aito/cgi-bin. It is not recommended to include
current directory to this path.
</ul>
<p>
The CGI script can use special header `w3m-control:' to control w3m.
This field can take any function (see <a href="README.func">README.func</a>),
and the specified function is invoked after the document is displayed.
For example, The CGI output
<pre>
Content-Type: text/plain
W3m-control: BACK
</pre>
will display blank page and delete that buffer immediately.
This is useful when you don't want to display any page after
the script is invoked. The next example
<pre>
Content-Type: text/plain
W3m-control: DELETE_PREVBUF
contents.....
</pre>
will override the current buffer.
<p>
One w3m-control: header have to contain only one function, but you can
include more than one w3m-control: lines in the HTTP header.
In addition, you can specify an argument to GOTO function:
<pre>
Content-Type: text/plain
W3m-control: GOTO http://www.yahoo.com/
</pre>
This example works exactly the same way to the Location header:
<pre>
Content-Type: text/plain
Location: http://www.yahoo.com/
</pre>
Note that this header has no effect when the CGI script is invoked
through HTTP server.
