<p>hooks.pl -- Perl hooks for the ELinks text WWW browser</p>
<h1 id="DESCRIPTION">DESCRIPTION</h1>
<p>This file contains the Perl hooks for the ELinks text WWW browser.</p>
<p>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.</p>
<h1 id="CONFIGURATION-FILE">CONFIGURATION FILE</h1>
<p>This hooks file reads its configuration from <i>~/.elinks/config.pl</i>. The following is an example of the configuration file:</p>
<pre><code> 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</code></pre>
<p><i>Developer's usage</i>: The function <i>loadrc()</i> takes a preference name as its single argument and returns either an empty string if it is not specified, <i>yes</i> for a true value (even if specified like <i>sure</i> or <i>why not</i>), <i>no</i> for a false value (even if like <i>nah</i>, <i>off</i> or <i>0</i>), or the lowercased preference value (like <i>cnn</i> for <code>weather: CNN</code>).</p>
<h1 id="GOTO-URL-HOOK">GOTO URL HOOK</h1>
<p>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.</p>
<ul>
<p><i>Developer's usage</i>: The function <i>goto_url_hook</i> is called when the hook is triggered, taking the target URL and current URL as its two arguments. It returns the final target URL.</p>
<p>These routines do a name->URL mapping - for example, the <i>goto_url_hook()</i> described above maps a certain prefix to <code>google</code> and then asks the <i>search()</i> mapping routine described below to map the <code>google</code> string to an appropriate URL.</p>
<p>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.</p>

<h1 id="FOLLOW-URL-HOOK">FOLLOW URL HOOK</h1>
<p>These hooks effect a URL before ELinks has a chance to load it.</p>
<ul>
<p><i>Developer's usage</i>: The function <i>follow_url_hook</i> is called when the hook is triggered, taking the target URL as its only argument. It returns the final target URL.</p>
<p>Bork! Bork! Bork!</p>
<p>Rewrites many <i>google.com</i> URLs.</p>
<p>NNTP over Google</p>
<p>Translates any <i>nntp:</i> or <i>news:</i> URLs to Google Groups HTTP URLs.</p>
</ul>
<h1 id="PRE-FORMAT-HTML-HOOK">PRE FORMAT HTML HOOK</h1>
<p>When an HTML document is downloaded and is about to undergo the final rendering, this hook is called. This is frequently used to get rid of ads, but also various ELinks-unfriendly HTML code and HTML snippets which are irrelevant to ELinks but can obfuscate the rendered document.</p>
<p>Note that these hooks are applied <b>only</b> before the final rendering, not before the gradual re-renderings which happen when only part of the document is available.</p>
<ul>
<p><i>Developer's usage</i>: The function <i>pre_format_html_hook</i> is called when the hook is triggered, taking the document's URL and the HTML source as its two arguments. It returns the rewritten HTML code.</p>
<p>Slashdot Sanitation</p>
<p>Kills Slashdot's Advertisements. (This one is disabled due to weird behavior with fragments.)</p>
<p>Obvious Google Tips Annihilator</p>
<p>Kills some irritating Google tips.</p>
<p>SourceForge AdSmasher</p>
<p>Wipes out SourceForge's Ads.</p>
<p>Gmail's Experience</p>
<p>Gmail has obviously never met ELinks...</p>
<p>Source readability improvements</p>
<p>Rewrites some evil characters to entities and vice versa. These will be disabled until such time as pre_format_html_hook only gets called for content-type:text/html.</p>
</ul>
<h1 id="PROXY-FOR-HOOK">PROXY FOR HOOK</h1>
<p>The Perl hooks are asked whether to use a proxy for a given URL (or what proxy to actually use). You can use it if you don't want to use a proxy for certain Intranet servers but you need to use it in order to get to the Internet, or if you want to use some anonymizer for access to certain sites.</p>
<ul>
<p><i>Developer's usage</i>: The function <i>proxy_for_hook</i> is called when the hook is triggered, taking the target URL as its only argument. It returns the proxy URL, empty string to use no proxy or <i>undef</i> to use the default proxy URL.</p>
<p>No proxy for local files</p>
<p>Prevents proxy usage for local files and <code>http://localhost</code>.</p>
</ul>
<h1 id="QUIT-HOOK">QUIT HOOK</h1>
<p>The Perl hooks can also perform various actions when ELinks quits. These can be things like retouching the just saved "information files", or doing some fun stuff.</p>
