I set up a DokuWiki for personal use in Hebrew. This serves for both Hebrew and English articles. The problem was that there was no way to have content in a left-to-right direction as all pages were governed by a general RTL directive… I ended up writing a small plugin adding <LTR> and </LTR> tags to allow for a section to be displayed left to right (ie. English). I based it on the demo example (color) from the plugins tutorial.

Something I was not able to figure out is why I can't get the headings to work in it (for some reason they are left unparsed). If anyone can give me insight on this, I'd appreciate it.

Another issue I think I'll try to look at is adding a button in the formatting toolbar that will switch the direction of the input textbox (so that the user can decide what direction the editing input will be if the browser doesn't allow for this - like Firefox).

Here is the plugin (just create a directory called LTR under the plugins directory, create a file syntax.php in it and copy the following code into it):

<?php

      break;

      break;
    }
    return array();
  }
 
  /**

       list($state, $match) = $data;

Keep up the good work guys.

Discussion

  • Ariel : I was just planning to write a similar plugin which would allow <HE> in English texts and <EN> in Hebrew texts
    your plugin will save me a lot of sweat ;-)
    FYI : I work with IE6/IE7/Firefox under Windows with Hebrew support :
    In Edit Mode Ctrl-RightShift changes editing direction to RTL whereas Ctrl-LeftShift changes to LTR
    (and BTW Alt-AnyShift changes language mode independent of editing direction)
    I don't know what happens in other Operating systems

Just to note that the option $conf['htmlok'] has to be 1 in order for the plugin to work.
