<para>
|
|
<parameter>--with-screen=ncursesw</parameter>: This switch enables
|
|
the use of advanced wide-character support present in the system
|
|
<application>NCurses</application> library. This is needed for
|
|
proper display of characters and line wrapping in multibyte locales.

<para>

it if your ISP provides an IPv6 configuration.

</para>
|
|

<para>
|
|
<parameter>--enable-locale-charset</parameter>: This switch allows
|
|
<application>Lynx</application> to deduce the proper character encoding
|
|
for terminal output from the current locale. A configuration step is
|
|
still needed (see below), but unlike the situation without this switch,
|
|
the configuration step becomes the same for all users (without the
|
|
switch one must specify the display character set explicitly). This is
|
|
important for environments such as a LiveCD, where the amount of
|
|
system-specific configuration steps has to be reduced to the minimum.

<para>

questions about cookies and SSL certificates).

<para>

<option>--with-gnutls</option>: This enables experimental support

<parameter>--with-ssl</parameter> switch if you want to use gnutls.

installation, this target installs the documentation and help files.

The proper way to get the display character set is to examine the
|
|
current locale. However, <application>Lynx</application> does not do
|
|
this by default. As the <systemitem class="username">root</systemitem>
|
|
user, change this setting:
|
|
</para>
|
|
|
|
<screen role="root"><userinput>sed -e '/#LOCALE/ a LOCALE_CHARSET:TRUE' \
|
|
-i /etc/lynx/lynx.cfg</userinput></screen>
|
|
|
|
<para>
|
|
The built-in editor in <application>Lynx</application> <xref
|
|
linkend="locale-wrong-multibyte-characters"/>. This issue manifests
|
|
itself in multibyte locales, e.g., as the Backspace key not erasing
|
|
non-ASCII characters properly, and as incorrect data being sent to the
|
|
network when one edits the contents of text areas. The only solution
|
|
to this problem is to configure <application>Lynx</application> to
|
|
use an external editor (bound to the <quote>Ctrl+X e</quote> key
|
|
combination by default). Still as the
|
|
<systemitem class="username">root</systemitem> user:
|
|
</para>
|
|
|
|
<screen role="root"><userinput>sed -e '/#DEFAULT_ED/ a DEFAULT_EDITOR:vi' \
|
|
-i /etc/lynx/lynx.cfg</userinput></screen>
|
|
|
|
<para>
|
|
<application>Lynx</application> handles the following values of
|
|
the DEFAULT_EDITOR option specially by adding cursor-positioning
|
|
arguments: <quote>emacs</quote>, <quote>jed</quote>,
|
|
<quote>jmacs</quote>, <quote>joe</quote>, <quote>jove</quote>,
|
|
<quote>jpico</quote>, <quote>jstar</quote>, <quote>nano</quote>,
|
|
<quote>pico</quote>, <quote>rjoe</quote>, <quote>vi</quote> (but not
|
|
<quote>vim</quote>: in order to position the cursor in
|
|
<xref linkend="vim"/>, set this option to <quote>vi</quote>).
|
|
</para>
|
|
|
|
<para>
|
|
By default, <application>Lynx</application> doesn't save cookies
|
|
between sessions. Again as the
|
|
<systemitem class="username">root</systemitem> user, change this
|
|
setting:
|
|
</para>
|
|
<screen role="root"><userinput>sed -e '/#PERSIST/ a PERSISTENT_COOKIES:TRUE' \
|
|
-i /etc/lynx/lynx.cfg</userinput></screen>
|
|
|
|
<para>
|
|
Many other system-wide settings such as proxies can also be set
|
|
in the <filename>/etc/lynx/lynx.cfg</filename> file.
