-Hacked By You+====== InterWiki Links ====== 
 + 
 +The original idea of InterWiki was to have one large distributed [[wp>Wiki]] over the whole Internet. Today its more of an easy way to link from one wiki to another by having some simple link syntax to accomplish so. 
 + 
 +In [[DokuWiki]] this is done by prefixing Wiki [[pagenames]] with a shortcut separated by a ''>'' character. 
 + 
 +Examples: 
 +| %%[[wp>InterWiki]]%%    | [[wp>InterWiki]]    | links to the English language Wikipedia                                                                                                                                                                     | 
 +| %%[[phpfn>random]]%%    | [[phpfn>random]]    | links to a function in the PHP manual                                                                                                                                                                       | 
 +| %%[[google>Wiki]]%%     | [[google>Wiki]]     | links to a Google search                                                                                                                                                                                    | 
 +| %%[[doku>interwiki]]%%  | [[doku>interwiki]]  | links to the DokuWiki wiki                                                                                                                                                                                  | 
 +| %%[[skype>echo123]]%%   | [[skype>echo123]]   | Links that opens Skype, ready to call Skype Test Call (echo123)                                                                                                                                             | 
 +| %%[[this>feed.php]]%%   | [[this>feed.php]]   | links to your wiki's URL. The example links to the local [[syndication|XML feed]]. ''%%[[this>]]%%'' is a special case and the only interwiki link which **cannot be configured** through any config file.  | 
 + 
 +Here's an example of how to access an arbitrary file in dokuwiki's data/media directory by clicking on an image. It's useful for videos and pdf files. 
 + 
 +  [[this>lib/exe/fetch.php?media=video.ogg|{{image.png?300}}]] 
 + 
 +Since DokuWiki [[changes#release_2017-02-19e_frusterick_manners|Release 2017-02-19b “Frusterick Manners”]], interwiki substitution for external images is available. 
 + 
 + {{ phpfn>images/php.gif?96}} 
 + 
 +  {{ phpfn>images/php.gif?96}}

 +===== Configuring InterWiki Shortcuts ===== 
 + 
 +InterWiki shortcuts are defined in two files: 
 +  * the ''[[https://github.com/splitbrain/dokuwiki/blob/master/conf/interwiki.conf|<dokuwiki_conf>/interwiki.conf]]'' file.\\ This is the default file, it contains a few predefined useful shortcuts (more can be found in [[http://usemod.com/intermap.txt]]). It is possible to modify this file, however this could result in your changes being overwritten when upgrading DokuWiki. 
 +  * the ''<dokuwiki_conf>/interwiki.local.conf'' file.\\ This is the file to add your own interwiki links. This will prevent the links from being overwritten on an update. 
 + 
 +The interwiki shortcut has to be in lowercase and follow the [[pagename]] rules. 
 + 
 +The format of the interwiki config file is: 
 + 
 +  <shortcut>      <url to wiki> 
 + 
 +The shortcut is the one you will be able to use in the link later. In the URL you can use some placeholders to be more flexible in linking. If no placeholder is given the [[phpfn>rawurlencode|URL-encoded]] wikiname will be appended to the URL. These placeholders are available: 
 + 
 +^ Placeholder  ^  Replaced by                                                                          ^ 
 +| {URL}        | URL-encoded wikiname (the part which is appended to the URL in interwiki.local.conf) 
 +| {NAME}       | wikiname without any encoding                                                         | 
 +| {SCHEME}     | scheme part if a URL was given as wikiname                                           | 
 +| {HOST}       | host part if a URL was given as wikiname                                             | 
 +| {PORT}       | port part if a URL was given as wikiname                                             | 
 +| {PATH}       | path part if a URL was given as wikiname                                             | 
 +| {QUERY}      | query part if a URL was given as wikiname                                            | 
 + 
 +The last 5 parameters are useful when creating interwikilinks to cachesystems.  
 + 
 +For example cached links with the old, not longer working, [[wp>Coral Content Distribution Network]] could be used by a ''coral'' shortcut, defined using a couple of placeholders: 
 + 
 +<code>coral http://{HOST}.{PORT}.nyud.net:8090{PATH}?{QUERY}</code> 
 + 
 +For example, [[https://wiki.ubuntu.com/|Ubuntu's wiki]] uses namespaces and pagenames like this ''LaptopTestingTeam/ToshibaPortegeM700'' and without using ''{NAME}'' as a placeholder in your interwiki.local.conf file, you'll get a "Not Found" error on their wiki, because it'll interpret the forward slash as a ''%2F'' ; so what you can do is add this line to your interwiki.local.conf: 
 + 
 +<code>ubuntu https://wiki.ubuntu.com/{NAME}</code> 
 + 
 +and now create your link to it like this: 
 + 
 +<code>[[ubuntu>LaptopTestingTeam/ToshibaPortegeM700|Ubuntu on Toshiba Portege M700 Tablet]]</code> 
 + 
 +If the wikiname will already include encoded characters (ex: ''%26'' for ''&'') use {PATH} in your interwiki.local.conf definition. 
 + 
 +==== Inter(n)wiki links ==== 
 + 
 +To refer to certain namespaces within you own wiki:((Note: the link would always appeare like if page already exist. No preprove.)) 
 + 
 +<code><shortcut>      <dokuwiki_root>:ns:..:</code> 
 + 
 +For example: ''enlib      doku.php?id=:en:lib:'' would address pages in the namespace '':en:lib:pagename'' if using the link syntax ''enlib>pagename''
 +===== Configuring InterWiki Shortcut Icons ===== 
 + 
 +Interwiki icons should have a size of 16x16 pixels, be in PNG or GIF format, and be named after the shortcut. 
 +  * ''<dokuwiki_root>/lib/images/interwiki''\\ The directory to place the image files in. 
 + 
 +You should also purge [[caching|cached]] PNG and GIF images as well as the CSS Files if you have the default image instead of the one you uploaded. 
 + 
 +<code> 
 +rm -rf <dokuwiki_data>/data/cache/*/*.{gif,png,css} 
 +</code> 
 + 
 +It may actually be enough to invalidate the CSS caching by re-saving in the config manager ('re-saving' means pressing the save button of config manager without any changes of config options). 
 + 
 +If you want to disable all or some kind of link icons, refer to [[tips:disabling link icons]].
