One could generalize that to - add arbitrary attributes. - - One could also add class attributes to <a> and/or <img> elements. - I do not see the need for such modifications. If however this is - to be done in the future one would need to add 'html_class' key to the kw dictionary - with a corresponding value to add class to <img> element. To add class to <a> element - one needs to add 'css_class' key with a corresponding value to the dictionary passed to - pagelink call. - - Reimar Bauer: - 2004-12-23 Adapted to MoinMoin Version 1.3.1-1 - 2004-12-23 Syntax change Version 1.3.1-2 - width and height and probably other keywords must be given as keywords (e.g. height=20) - 2004-12-31 Version 1.3.1-3 code clean up - 2005-01-16 Bug fixed in the errorhandler - found and patched by Malte Helmert - 2005-03-05 Version 1.3.3-5 Bug fixed found by cypress ("If I put <<ImageLink(moinmoin.png)>> it bombs") - 2005-03-28 Version 1.3.3-6 feature request added by CDPark: - "Can we use an external image? And an external target?" - 2005-04-16 Version 1.3.3-7 no default alt tag definition as requested by CDPark and AlexanderSchremmer - - Chong-Dae Park: - 2005-04-17 Version 1.3.3-8 code refactored - IMG with no alt tag is not recommended in the HTML standard. - It keeps a user specified alt tag. If there is none, it tries to make on using the WikiName - or image name instead. - - Reimar Bauer: - 2005-04-21 Version 1.3.3-9 bug fixed - When the image does not exist yet, it gives you a "Upload Image" link, this link does not - work. I suspect that this only is a problem on sub-pages, caused by incorrect escaping of - "/". -- CraigJohnson - - 2005-12-19 Versiom 1.5.0-10 feature added to link to images on different wiki pages - 2006-02-14 Version 1.5.2-11 bug fixed for filename of attached image is Chinese (encode added) - 2006-02-22 Version 1.5.2-12 code refactored - - Thomas Waldmann - 2006-03-10 code refactored - - Reimar Bauer - 2006-09-22 bug fix of image linked to attachment and inline - 2006-10-08 patch of DavidLinke added and keys now only lowercase used - 2006-12-16 interwikilink for pages added - - @copyright: 2001 by Jeff Kunce, - 2004 by Marcin Zalewski, - 2006 by MoinMoin:ThomasWaldmann, - 2004-2007 by MoinMoin:ReimarBauer - - @license: GNU GPL, see COPYING for details. -""" - -from MoinMoin import wikiutil -from MoinMoin.action import AttachFile - -def _is_URL(text): - """ Answer true if text is an URL. - The method used here is pretty dumb.
