Req #77018 [NEW]: Generate 'link' elements in HTML head, for rel="next", "prev", "up", "start"

From: phil at catalyst dot net dot nz Operating system: PHP version: master-Git-2018-10-16 (Git) Package: Doc Build problem Bug Type: Feature/Change Request Bug description:Generate 'link' elements in HTML head, for rel="next", "prev", "up", "start" Description: ------------ Certain web browsers can utilise navigation metadata to make life easier for the user. By providing 'link' elements in the HTML 'head' with 'rel' attributes for the "next", "prev", "up", and "start" pages, users of these browsers can easily skip around the documentation. Even better, some browsers can use this metadata to let the user interactively search throughout the documentation, taking the user to the next page in the sequence containing a match (by following the "next" links until a page containing a match is arrived at). The web browser built into Emacs is one such example. When using the offline documentation, this search ability can be incredibly useful, due to its sheer convenience for the user, in combination with the speed of offline access. It would be fantastic if the documentation contained these navigation link elements. Especially in the downloadable archives (e.g. php_manual_en.tar.gz), as the aforementioned searching is fast for local files. Note that this same data is already being established and generated as the .manualnavbar div at the top of the page, so I believe this feature request is just to add an additional rendering of that data, which is hopefully quite straightforward to implement. The following is an example for the "Variables" section landing page language.variables.html: <head> <link rel="prev" title="Type Juggling" href="language.types.type-juggling.html"> <link rel="next" title="Basics" href="language.variables.basics.html"> <link rel="up" title="Language Reference" href="langref.html"> <link rel="start" title="PHP Manual" href="index.html"> </head> Which is analogous to the following markup included in the <body>: <div class="manualnavbar" style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="language.types.type-juggling.html">Type Juggling</a></div> <div class="next" style="text-align: right; float: right;"><a href="language.variables.basics.html">Basics</a></div> <div class="up"><a href="langref.html">Language Reference</a></div> <div class="home"><a href="index.html">PHP Manual</a></div> </div> -- Edit bug report at https://bugs.php.net/bug.php?id=77018&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77018&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77018&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77018&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77018&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77018&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77018&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77018&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77018&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77018&r=support Expected behavior: https://bugs.php.net/fix.php?id=77018&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77018&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77018&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77018&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77018&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77018&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77018&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77018&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77018&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77018&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77018&r=mysqlcfg
