<para><parameter>--sysconfdir=/etc/lynx</parameter>: This parameter is

This parameter is used so that the documentation files are installed into

|
|
instead of
|
|
<filename class="directory">/usr/share/lynx_{doc,help}</filename>.</para>

<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>

<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>

<application>Lynx</application> to print translated messages (such as

questions about cookies and SSL certificates).</para>

linking SSL into <application>Lynx</application>.</para>

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

documentation files.</para>

<title>Configuration Information</title>
|
|
|
|
<para>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. Change this setting:</para>
|
|
|
|
<screen><userinput>sed -i 's/#\(LOCALE_CHARSET\):FALSE/\1:TRUE/' /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):</para>
|
|
<screen><userinput>sed -i 's/#\(DEFAULT_EDITOR\):/\1:vi/' /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>
|
|
|
|
<!-- For editors:
|
|
The list should be updated from src/LYEdit.c when a new version of Lynx
|
|
comes out. Anyway, upstream promises (in
|
|
ftp://lynx.isc.org/current/CHANGES ) to fix the multibyte issue for 2.8.7
|
|
|
|
2.8.7rel.1: This needs to be checked.
|
|
-->
|
|
|
|
<para>By default, <application>Lynx</application> doesn't save cookies
|
|
between sessions. Change this setting:</para>
|
|
<screen><userinput>sed -i 's/#\(PERSISTENT_COOKIES\):FALSE/\1:TRUE/' /etc/lynx/lynx.cfg</userinput></screen>
|
|
|

in the <filename>/etc/lynx/lynx.cfg</filename> file.</para>
