=head1 NAME
hooks.pl -- Perl hooks for the ELinks text WWW browser
=head1 DESCRIPTION
This file contains the Perl hooks for the ELinks text WWW browser.
These hooks change the browser's behavior in various ways. They allow
shortcuts to be used in the Goto URL dialog, modifying the source of a page,
proxy handling, and other things such as displaying a fortune at exit.

use warnings;
use diagnostics;
=head1 CONFIGURATION FILE
This hooks file reads its configuration from I<~/.elinks/config.pl>.
The following is an example of the configuration file:
bork: yep # BORKify Google?
collapse: okay # Collapse all XBEL bookmark folders on exit?
email: # Set to show one's own bugs with the "bug" prefix.
external: wget # Send the current URL to this application.
fortune: elinks # *fortune*, *elinks* tip, or *none* on quit?
googlebeta: hell no # I miss DejaNews...
gotosearch: why not # Anything not a URL in the Goto URL dialog...
ipv6: sure # IPV4 or 6 address blocks with "ip" prefix?
language: english # "bf nl en" still works, but now "bf nl" does too
news: msnbc # Agency to use for "news" and "n" prefixes
search: elgoog # Engine for (search|find|www|web|s|f|go) prefixes
usenet: google # *google* or *standard* view for news:// URLs
weather: cnn # Server for "weather" and "w" prefixes
# news: bbc, msnbc, cnn, fox, google, yahoo, reuters, eff, wired,
# slashdot, newsforge, usnews, newsci, discover, sciam
# search: elgoog, google, yahoo, ask jeeves, a9, altavista, msn, dmoz,
# dogpile, mamma, webcrawler, netscape, lycos, hotbot, excite
# weather: weather underground, google, yahoo, cnn, accuweather,
# ask jeeves
I<Developer's usage>: The function I<loadrc()> takes a preference name as its
single argument and returns either an empty string if it is not specified,
I<yes> for a true value (even if specified like I<sure> or I<why not>), I<no>
for a false value (even if like I<nah>, I<off> or I<0>), or the lowercased
preference value (like I<cnn> for C<weather: CNN>).
=cut
sub loadrc($)
{
my ($preference) = @_;
my $configperl = $ENV{'HOME'} . '/.elinks/config.pl';
my $answer = '';

=head1 GOTO URL HOOK
This is a summary of the shortcuts defined in this file for use in the Goto URL
dialog. They are similar to the builtin URL prefixes, but more flexible and
powerful.
=over
I<Developer's usage>: The function I<goto_url_hook> is called when the hook is
triggered, taking the target URL and current URL as its two arguments. It
returns the final target URL.
These routines do a name->URL mapping - for example, the I<goto_url_hook()>
described above maps a certain prefix to C<google> and then asks the
I<search()> mapping routine described below to map the C<google> string to an
appropriate URL.
There are generally two URLs for each name. One to go to the particular URL's
main page, and another for a search on the given site (if any string is
specified after the prefix). A few of these prefixes will change their
behavior depending on the URL currently beung displayed in the browser.

# Don't call them "dumb". They hate that. Rather, "interactivity challenged".

also various ELinks-unfriendly HTML code and HTML snippets which are irrelevant

before the gradual re-renderings which happen when only part of the document is
available.

you want to use some anonymizer for access to certain sites.
