 Set SHORTDESCRIPTION = Integration of the OSCOM Kupu WYSIWYG editor with TWiki.
 
-->

OSCOM Kupu WYSIWYG editor

The integration uses the TWiki:Plugins.WysiwygPlugin to translate text to and from a format that Kupu can edit.

Caveat: KupuContrib is designed for editing TWiki topics, not as a general purpose HTML editor. It will work fine on topics that contain text, TML formatting, and most HTML. However, because of the complexity of transforming TML into HTML and back, complex TML, and mixing HTML and TML may not give the results you expect. You are recommended to use the standard browser textarea editor for editing existing topics that contain mixed HTML and TML, or complex %TML%-type variables.

How to use the editor

• "Insert No-Op" inserts a <nop> region. Any TWiki syntax such as wikiwords or variables inside the region will be disabled in the rgeion. $lt;nop> regions may not extend over line breaks.
• The rightmost drop-down will give you a menu of TWiki variables that can be inserted. Any of these variables can be edited after they have been placed in the text, for example to add parameters.
• "Insert a WikiWord" will give you a menu of topics in the current web that can be inserted. Topics are inserted as links, though typing wikiwords in plain text will work just as well.
• Watch out for the <> button on the right of the toolbar. It lets you switch into an HTML view, which can be very useful when you can't get your formatting right.
• In TWiki, a totally empty table cell causes the cell to be merged with the cell immediately to the left. To make this effect more transparent in the editor, these empty cells are shown with the text "%SPAN%" in them. In Kupu, if you add %SPAN% to a table cell, then all the rest of the content will be thrown away and the cell will be converted to an empty table cell. Note that this only applies to tables that are converted to TWiki syntax.

Kupu Notes

Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server where TWiki is running.

Like many other TWiki extensions, this module is shipped with a fully automatic installer script written using the BuildContrib.

• If you have TWiki 4.1 or later, and Perl 5.8, you can install from the configure interface (Go to Plugins->Find More Extensions)
  • The webserver user has to have permission to write to all areas of your installation for this to work.
• If you have a permanent connection to the internet (and Perl 5.8), you are recommended to use the automatic installer script
  • Just download the KupuContrib_installer perl script and run it.
• Notes:
  • The installer script will:
    • Automatically resolve dependencies,
    • Copy files into the right places in your local install (even if you have renamed data directories),
    • check in new versions of any installed files that have existing RCS histories files in your existing install (such as topics).
    • If the $TWIKI_PACKAGES environment variable is set to point to a directory, the installer will try to get archives from there. Otherwise it will try to download from twiki.org or cpan.org, as appropriate.
    • (Developers only: the script will look for twikiplugins/KupuContrib/KupuContrib.tgz before downloading from TWiki.org)
  • If you don't have a permanent connection, you can still use the automatic installer, by downloading all required TWiki archives to a local directory.
    • Point the environment variable $TWIKI_PACKAGES to this directory, and the installer script will look there first for required TWiki packages.
      • $TWIKI_PACKAGES is actually a path; you can list several directories separated by :
    • If you are behind a firewall that blocks access to CPAN, you can build a local CPAN mini-mirror, as described at http://twiki.org/cgi-bin/view/Codev/BuildingDakar#CPAN_local_minimirror
• If you don't want to use the installer script, or have problems on your platform (e.g. you don't have Perl 5.8), then you can still install manually:
  1. Download and unpack one of the .zip or .tgz archives to a temporary directory.
  2. Manually copy the contents across to the relevant places in your TWiki installation.
  3. Check in any installed files that have existing ,v files in your existing install (take care not to lock the files when you check in)
  4. Manually edit LocalSite.cfg to set any configuration variables.
  5. Run configure and enable the module, if it is a plugin.
  6. Repeat from step 1 for any missing dependencies.

Do not forget to enable the WysiwygPlugin in configure or it won't work.

• To enable the editor in one of your skins, add the following link to the skin alongside or in place of the existing 'edit' link:
  <a href="%SCRIPTURLPATH%/edit%SCRIPTSUFFIX%/%WEB%/%TOPIC%?skin=kupu">Kupu</a>
  As you can see this is just a standard edit link with the 'kupu' skin in place of the usual edit skin. Here it is for this topic: Kupu. Try clicking on it, but do not save!

If you are using TWiki-4.0.0 or later with pattern skin, the %COMPOSER% global TWiki variable is used to control the skin used for the WYSIWYG editor link. You can define this variable to the empty string to disable WYSIWYG editing on a site, per-web, per-user or per-topic basis. Set COMPOSER to kupu to enable this module.

Other Settings

The editor template includes a number of files that can be used for other settings. These files are not included in the distribution, so that you can easily create your own local content.

Known problems

Can't undo all functions (Kupu + browser)

Because of limitations in the browsers, the editor does not support PRE blocks. All PRE blocks will be converted to TWiki verbatim blocks on save. This can cause some confusion, especially when editor formatting controls (such as "bold") have been used to format text in a PRE block. Users are advised to use only plain text in PRE (verbatim) blocks.

No Safari support

Contrib Version:	12392
Change History:	<-- versions below in reverse order -->
12119	Split out of WysiwygPlugin
11538	Minor doc updates, minor fixes to spacing in lists, integrated Koen Marten's template topic patch
9671	Item2025 corrected handling of SPAN and FONT tags used for colour changes
9566	Item1890 doc update
9565	Item1890 Item1041 Item944 Much more aggressive cleanup of HTML pasted in from external sources. Excessively verbose HTML (e.g. from Outlook) was causing apparent infinite looing behaviour.
8867	Item1176 commented out Cairo version of header handler
8780	Item1625 disable expansion of twiki variables in urls where there are other twiki variables that can't be expanded
8779	Item1530 support for templatetopic when editing new topics
8592	Item1532 WysiwygPlugin: Added two more do-not-edit-if-topic-contains parameters, pre+comments
8590	Item1532 WysiwygPlugin: Kenneths suggestion on proper handling of HTML comments (incl. change to kupu)
8572	Item1529 evil, evil. The XMLSerializer in IE isn't happy serializing the DOM. I have no idea why. Kupu manages to get away with this because it passes the DOM through the XML validator, which I had to disable because it strips comments. So, for now, the IE implementation will strip comments - but at least you can save again
8538	Item1501 table handling was a bit spazzy. Several problems fixed.
8535	Item1518 moved icon and string lists into topics, updated screenshot
8531	Item1392 reversed the sense of the navigate-away condition, again
8466	Item1486 added WYSIWYG_EXCLUDE to allow exclusion of 'uneditable' content
8463	Item1486 was stripping comments, wrongly. Had to disable the kupu filters completely, they just do too much damage.
8401	Item1457 corrected problem with bullet list at top of topic
8388	Item1445 fix for a javascript error, introduced by previous fix
8387	Item1445 small usability improvements
8334	Item663 TWiki.org doc merge: Fix incorrect link to kupu website
8327	Item1411 handle case of the result of a TWiki variable being nopped
8312	Item1317 wrong result returned from generation function when expanding HTML embedded in verbatim block
8301	Item1397 removed excess space after sqaub links
8300	Item1231 added %SPAN% to indicate a spanned-over cell in the editor. Improved handling of HTML in verbatim tags by inserting line breaks is the tag type calls for it, before removing the HTML.
8276	Item1215 added WYSIWYG_ICONS and WYSIWYG_TAGS to support user customisation of icon images and twiki variables that can be inserted
8274	Item1314 debugging in case the hang happens again; and made sure to default the editor just in case
8273	Item1315 short forms must be terminated by one of the same characters that terminate wikiwords
8272	Item1391 added special interpretation of IMG tags to expand selected TWiki variables within SRC attributes
8271	Item1340 refined handling of NOP to cover abbrevs
8270	Item1311 removed excess space inserted in headings
8269	Item1339 changed from using arbitrary attribute for notoc to a new CSS class. Arbitrary attributes are stripped by Kupu before save.
8268	Item1344 strip ^Ms inserted by Sarissa during serialisation on IE
8267	Item1394 still can't get text styles to work properly in IE; but I am now firmly of the opinion that the fault lies with the browser, and not with Kupu.
8232	Item1341 added appropriate CSS class
8152	Item1313 added caveat about editing complex HTML and mixed HTML-TML
8151	Item1334 headers not handled properly in Cairo version
8108	Item1318 corrected table/list parser for tables embedded in bulleted lists
8106	Item1310 support for <nop/>
8105	Item1317 support for limited case of nopped variable
8104	Item1320 corrected interpretation of relative URL path in [[]]
8091	Item1259 changed comment handling; rather than trying to create HTML, which gets munged, create an HTML comment. This will only be editable by switching to source view, but hey, it's supposed to be WYSIWYG. Note that this also means that comments in pasted HTML should be retained now
8063	Item1042 spec of SCRIPTURL changed
7904	Item1189 reverting accidental checkin of experimental code
7903	Item1189 filter whitelist is not good enough; need to generate B and I nodes. templates/ pub/TWiki/WysiwygPlugin
7902	Item1189 it took bloody ages to track down, but finally discovered that bold and italic were being filtered out of spans by Kupu 1.3.2.... too smart for it's own good. So added them to the filter whitelist, and it works again.
7873	Item1189 added pre save filter to try and find where the attributes are disappearing to in FF
7872	Item1187 for lack of an s on an RE, the nation was lost (well, the multi-line comment actually). Thanks Kenneth!
7871	Item859 solved issue with non-display of inserted images. Was due to the use of an onSubmit handler to close the dialog, rather than an onLoad handler triggered when the IFRAME that contains the result is loaded.
7869	Item1172 had to rewrite big chunk of the table popup to get it working with 1.3.2
7858	Item1151 rewrote link handlings stuff to leverage browser better
7854	Item1175 escape wikiwords within squabs
7815	Item1158 works for Cairo now as well
7814	Item1158 first implementation of AJAX interface to allow selectoin of topics from other webs
7812	Item1154 removed non-existent scull.gif
7811	Item1155 added extra recursion block, as Item1155 suggests it is needed
7801	Item1042 All sorts of clever tricks to handle expansion/compression of a subset of TWiki variables when they are used in URLs. Not a complete solution, but better than it was.
7799	Item1024 caught out by recursive call to beforeCommonTagsHandler in Cairo (nasty)
7798	Item1042 whoops, broke \t conversion in Cairo
7789	Item1140 testcase for 1140
7788	Item1140 fix rewriting of img src urls (and updated MANIFEST for Kupu1.3.2)
7786	Item1042 extensive improvements to variable and URL recognition and conversion
7766	Item856 added doc on EDIT_SKIN to the plugin
7712	Item1074 upgrade to Kupu 1.3.2 complete (at last)
7710	Item1074 Fixed source edit mode
7709	Item1074 tidied up broken toolbar. There are still known issues
7700	Item1074 first pass at moving to Kupu 1.3.2.
7673	Item1037 insert wikiword only if selection is zero length
7672	Item977 changed to remove dangerous Cairo-based assumption, and use context ids instead
7630	Item1025 added 'escape clause' for old handlers implemented to support old TWiki releases without warnings
7506	Item941 Eliminated the last of the dynamic globals to try and solve saving problem. Can;t test with mod_perl, but is fine with speedycgi AFAICT
7456	Item873 minor issue; replace br with \n in pre
7455	Item873 obvious problem parsing closing pre tag on same line as open tag
7453	Item710 Handling HTML comments
7452	Item876 Item945: Item876: spacing around table cells, correct handling of variables. Had to compromise on handling [[]] but I think it's for the best.
7430	Item871 made sure that brackets are generated for non-wikiwords
7425	Item928 removed special interpretation of mailto links
7424	Item866 extended URL parsing to handle MAINWEB and TWIKIWEB twiki variables, in the same hacky way as the core.
7416	Item870 a couple of corner-cases for correct handling of twiki variables
7401	Item899 changed list generation to use spaces instead of tabs
7265	Item180 removed pointless, outdated dependency check from DateFieldPlugin
6935	Item622 reverted 3 specs to tabs in Set lines in plugins topics for kompatterbility with Kigh-roe
6905	Item622 tabs -> 3 spacesto avoid confusing the users
6850	Item638 added instruction to run configure to all install docs (I hope)
6827	Item569 added default RELEASE to everything that had a version, and removed a load of dead code that was getting in the way
6758	Item569 computed version numbers for plugins from the repository rev they were built from.
6504	Item436 incremented vernos of all changed plugins
6485	Item429 trying to make access controls clearer
6401	Item340 re-initialisation bug found by ColasNahaboo when using mod_perl; fixed by correctly re-initialising the parse stack for each run of the convertor
6284	Item340 Release 0.16 of WysiwygPlugin
6279	Item340 bugfixes for release 0.16 of WysiwygPlugin
6261	Item335 Switched PNGs to indexed mode, as transparency doesn't work on IE for RGB images
6238	Item332 Added context identifier to WysiwygPlugin, and a button to the pattern view template. If WysiwygPlugin is enabled, then the button will appear. Neat, huh?
6195	Item196 getting plugin test suites to pass. Doesn't mean the plugins actually work, just that the test suites run (which is a good indicator)
6174	Item168 checkpoint checking for 0.16
6151	Item186 more minor updates
6150	Item168 new icons, and a couple of bugfixes, to WysiwygPlugin
6092	Item196 more plugin and contrib fixes for develop; mainly just moving tests around and making sure they all pass.
6067	Item138 had to change to using beforeCommonTagsHandler and also escape % signs to prevent TWiki from rendering internal tags (as reported by Colas)
5979	Item168 corrected stupid error on IE; added screenshot
5977	Item168 release 0.13
5948	Item168 nearly ready for 0.13
5937	Item168 corrected images, twikified all images
