 Set SHORTDESCRIPTION = Integration of the TinyMCE WYSIWYG Editor
 
-->

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

Unlike the other editor integrations in TWiki, which install "Word in a Browser" style editors, this plugin is able to swap out the standard text areas in an edit and replace them with WYSIWYG editors. This means you get WYSIWYG editors for textareas in forms, as well as for the main text of the topic. It can also co-exist alongside other WYSIWYG editors, such as Kupu.

The editor automatically "switches itself off" (i.e. reverts to the old text-only window) when editing topics that contain TWiki content it can't handle, such as complex TWiki variables.

Editor Notes

The editor uses a translator module to convert from TWiki markup language (TML) to HTML and back. The translator converts special TWiki tags - such as %VARIABLES% - to plain text, and encloses them within HTML spans using a special style called WYSIWYG_PROTECTED. In this way the editor can detect text that is not meant to be HTML formatted. This style is also used to protect special text you enter into the editor from being interpreted when the topic is translated back into TML. If you want to add any special TWiki features that are sensitive to formatting, such as Set statements, then you have to format those regions using 'Protect on save' or 'Protect forever'.

Installation Instructions

NOTES:

• This plugin comes pre-installed on TWiki. You should only need to re-install if there is an upgrade to the plugin.
• It requires the very latest revision of WysiwygPlugin. It will not work with the version shipped with TWiki 4.1.2.
• When installed, it replaces the old "textarea" editor. If you want to maintain access to the old editor from the standard screens, follow the instructions under Configuring the buttons on TWiki < 4.2.0.

First follow the installation instructions to install the Plugin:

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 4.2 or later, you can install from the configure interface (Go to Plugins->Find More Extensions)
  • See the installation supplement on TWiki.org for more information.
• If you have any problems, then you can still install manually from the command-line:
  1. Download one of the .zip or .tgz archives
  2. Unpack the archive in the root directory of your TWiki installation.
  3. Run the installer script ( perl <module>_installer )
  4. Run configure and enable the module, if it is a plugin.
  5. Repeat for any missing dependencies.
• If you are still having problems, then instead of running the installer script:
  1. Make sure that the file permissions allow the webserver user to access all files.
  2. 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)
  3. Manually edit LocalSite.cfg to set any configuration variables.

• Enable the WysiwygPlugin in configure.
• Enable the TinyMCEPlugin in configure.
• Click on edit of any topic.

Settings

You can override this setting by defining TINYMCEPLUGIN_DEBUG to enable some simple debug features.

• Set DEBUG = 0

This setting contains all the options passed to the TinyMCE editor on startup. For a full explanation of the available options, and guidance on reconfiguring TinyMCE, see the Moxicode TinyMCE Wiki. Note the inclusion of the Pattern Skin standard CSS files in the content_css setting.

• Additional settings for specific browsers.
  • Warning: if you enable paste_auto_cleanup_on_paste then it automatically implies =past_use_dialog on all non-MSIE browsers.
  • Set INIT_MSIE = paste_auto_cleanup_on_paste : true
  • Set INIT_OPERA =
  • Set INIT_GECKO =
  • Set INIT_SAFARI =

You can override these settings in the same way as any other TWiki variable, by setting e.g. TINYMCEPLUGIN_INIT in the site, web or topic preferences. You are not recommended to edit the setting here.

• Some browsers don't support TinyMCE. You can prevent the editor from being invoked on these browsers by setting TINYMCEPLUGIN_BAD_BROWSERS to a regular expression that matches the user-agent string for any broken browsers. The default is (?i-xsm:Konqueror|Opera).

WYSIWYG_EXCLUDE - Prevent WYSIWYG editing

The global preference setting WYSIWYG_EXCLUDE can be set to make the plugin sensitive to what is in a topic, before allowing it to be edited. The comma separated list to fall back to text edit can include:

• html - HTML tags (e.g. <div>, not including <br>), or
• variables - simple variables (e.g. %SOMEVAR%) or
• calls - variables with parameters e.g. %SOMECALL{...}%
• pre - pre-formatted blocks (<pre>)
• comments - HTML comments (<!-- ... -->)
• script - inline HTML Script tags - default
• style - inline CSS style tags - default
• table - inline HTML tables (<table ..>. TML tables are not excluded)

If the plugin detects an excluded construct in the topic, it will refuse to allow the edit and will redirect to the default editor.

WYSIWYG_EDITABLE_CALLS - Exceptions to WYSIWYG_EXCLUDE

If you excluded calls in WYSIWYG_EXCLUDE, you can still define a subset of variables that do not block edits. this is done in the global preference setting WYSIWYG_EDITABLE_CALLS, which should be a list of variable names separated by vertical bars, with no spaces, e.g: * Set WYSIWYG_EDITABLE_CALLS = COMMENT|CALENDAR|INCLUDE

You should set WYSIWYG_EXCLUDE and WYSIWYG_EDITABLE_CALLS in TWikiPreferences, or in WebPreferences for each web.

WYSIWYGPLUGIN_PROTECT_EXISTING_TAGS - Protect specific tags originally in the topic text

The WYSIWYGPLUGIN_PROTECT_EXISTING_TAGS preference tells the translator that certain HTML tags which were originally in the topic text should remain as HTML tags; the translator will not try to convert them to TML. This protects the tags themselves, and not the contents enclosed between the <tag> and </tag>

The default setting for this preference is defined within the plugin. It corresponds to div, span.

This feature may be disabled by setting the preference to a single comma. This does not guarantee that HTML markup will be removed; the conversion of HTML tags to TML markup remains subject to the other controls provided by the WysiwygPlugin, including the WYSIWYGPLUGIN_STICKYBITS preference, <sticky> blocks, <literal> blocks and the rules applied to tables and lists.

WYSIWYGPLUGIN_PROTECT_TAG_BLOCKS - Protect specific tag blocks originally in the topic text

The WYSIWYGPLUGIN_PROTECT_TAG_BLOCKS preference tells the translator that certain HTML tag blocks which were originally in the topic text should remain as HTML blocks; the translator will not try to convert them to TML.

The default setting for this preference is defined within the plugin. It corresponds to script, style.

As an example, individual html tables can be protected by surrounding them with <sticky> .. </sticky> block.  However,if you want to have all =<table> markup preserved as entered into topics by default, rather than subject to WYSIWYG editing,  add =table to this list, and =<table> markup will become automatically sticky.

This feature may be disabled by setting the preference to a single comma.

WYSIWYGPLUGIN_STICKYBITS - Protect tags based upon their arguments

You can define the global preference WYSIWYGPLUGIN_STICKYBITS to stop the plugin from ever trying to convert specific HTML tags into TML when certain specific attributes are present on the tag. This is most useful when you have styling or alignment information in tags that must be preserved.

This preference setting is used to tell the translator which attributes, when present on a tag, make it "stick" i.e. block conversion back to TML.

For example, setting it to table=background,lang;tr=valign will stop the translator from trying to convert any table tag that has background or lang attributes, and any tr tag that has a valign attribute back to TWiki | table | column | markup (regardless of where that table tag comes from).

This setting is used only after the page has been processed by the editor. If the editor does not support a particular tag or attribute and the editor corrupts the tag, this setting will not be helpful. It is only used to prevent an HTML tag from being converted back to TML.

Format of the setting is tag1=attrib,attrib;tag2=attrib. Attributes delimited by comma, and tags delimited by semicolon.

• The left side of the equal sign is the tag.
• The right side of the equal sign is a comma delimited list of attributes to be matched.

If a matching tag is found, that matches any of the attributes listed, the tag will not be converted back to TML. You can use perl regular expressions to match tag and attribute names, so .*=id,on.* will ensure that any tag with an id or on* event handler is kept as HTML.

The default setting for this preference are hard coded in the plugin. If you wish to change the settings, the following list is the default setting coded in the plugin:

   * Set WYSIWYGPLUGIN_STICKYBITS = 
        (?!IMG).*=id,lang,title,dir,on.*;

If you edit using the plain-text editor, you can use the <sticky>..</sticky> tags to delimit HTML (or TML) that you do not want to be WYSIWYG edited.

Configuring the buttons on TWiki < 4.2.0

When installed on TWiki versions before 4.2.0, this plugin replaces the old textarea editor with the TinyMCE editor. The shock of this change can be too much for some older contributors, so we have written instructions for reconfiguring your templates in TWiki:Plugins.TinyMCEFrequentlyAskedQuestions.
