- * ---------------------

- * likely that you will have problems upgrading HTMLArea.
- *
- * Example on how to add a custom button when you construct the HTMLArea:
- *
- * var editor = new HTMLArea("your_text_area_id");
- * var cfg = editor.config; // this is the default configuration
- * cfg.btnList["my-hilite"] =
- * [ function(editor) { editor.surroundHTML('<span style="background:yellow">', '</span>'); }, // action
- * "Highlight selection", // tooltip
- * "my_hilite.gif", // image
- * false // disabled in text mode
- * ];
- * cfg.toolbar.push(["linebreak", "my-hilite"]); // add the new button to the toolbar
- *
- * An alternate (also more convenient and recommended) way to
- * accomplish this is to use the registerButton function below.

- <h1>HTMLArea -- the free<br/>customizable online editor</h1>
-
- <p>
- HTMLArea is a free, customizable online editor. It works inside your
- browser. It uses a non-standard feature implemented in Internet
- Explorer 5.5 or better for Windows and Mozilla 1.3 or better (any
- platform), therefore it will only work in one of these browsers.
- </p>
-
- <p>
- HTMLArea is copyright <a
- href="http://interactivetools.com">InteractiveTools.com</a> and
- released under a BSD-style license. HTMLArea is created and developed
- upto version 2.03 by InteractiveTools.com. Version 3.0 developed by
- <a href="http://students.infoiasi.ro/~mishoo/">Mihai Bazon</a> for
- InteractiveTools. It contains code sponsored by other companies as
- well.
- </p>
-
- <h2>Online demos</h2>
-
- <ul>
-
- <li><a href="example.html">HTMLArea standard</a> -- contains the core
- editor.</li>
-
- <li><a href="example-table-operations.html">HTMLArea + tables</a> --

-
- </ul>
-
- <h2>Installation</h2>
-
- <p>
- Installation is (or should be) easy. You need to unpack the ZIP file
- in a directory accessible through your webserver. Supposing you
- unpack in your <tt>DocumentRoot</tt> and your <tt>DocumentRoot</tt> is
- <tt>/var/www/html</tt> as in a standard RedHat installation, you need
- to acomplish the following steps: (the example is for a Unix-like
- operating system)
- </p>
-
- <pre style="margin-left: 2em"
->
-cd /var/www/html
-unzip /path/to/archive/HTMLArea-3.0-beta.zip
-mv HTMLArea-3.0-beta htmlarea
-find htmlarea/ -type f -exec chmod 644 {} \;
-find htmlarea/ -type d -exec chmod 755 {} \;
-find htmlarea/ -name "*.cgi" -exec chmod 755 {} \;</pre>
-
- <p>
- <strong>Notes.</strong> You may chose to symlink "htmlarea" to "HTMLArea-3.0-beta", in which case your server needs to be configured to
- "<tt>FollowSymLinks</tt>". You need to make sure that *.cgi files are
- interpreted as CGI scripts. If you want to use the SpellChecker
- plugin you need to have a recent version of Perl installed (I
- recommend 5.8.0) on the server, and the module Text::Aspell, available
- from CPAN. More info in "<a
- href="plugins/SpellChecker/readme-tech.html">plugins/SpellChecker/readme-tech.html</a>".
- </p>
-
- <p>About how to setup your pages to use the editor, please read the
- [outdated yet generally valid] <a
- href="reference.html">documentation</a>.</p>
-
- <h2>Status and links</h2>
-
- <p>HTMLArea has reached version 3.0. As of this version, it
- supports:</p>
-
- <ul>
-
- <li>Customizable toolbar</li>
-
- <li>Easy internationalization</li>
-
- <li>Plugin-based infrastructure</li>
-
- <li>Delivers W3-compliant HTML (with few exceptions)</li>
-
- <li>Has a subset of Microsoft Word's keyboard shortcuts</li>
-
- <li>Full-screen editor</li>
-
- <li>Advanced table operations (by external plugin
- "TableOperations")</li>
-
- <li>Spell checker (by external plugin "SpellChecker")</li>
-
- <li>probably more... ;-)</li>
-
- </ul>
-
- <p>We have a <a
- href="http://sourceforge.net/projects/itools-htmlarea/">project page</a>
- at <a href="http://sourceforge.net">SourceForge.net</a>. There you can
- also find out <a href="http://sourceforge.net/cvs/?group_id=69750">how
- to retrieve the code from CVS</a>, or you can <a
- href="http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/itools-htmlarea">browse
- the CVS online</a>. We also have a <a
- href="http://sourceforge.net/tracker/?atid=525656&group_id=69750&func=browse">bug
- system</a>, a <a
- href="http://sourceforge.net/tracker/?atid=525658&group_id=69750&func=browse">patch
- tracking system</a> and a <a
- href="http://sourceforge.net/tracker/?atid=525659&group_id=69750&func=browse">feature
- request page</a>.</p>
-
- <p>We invite you to say everything you want about HTMLArea <a
- href="http://www.interactivetools.com/forum/gforum.cgi?forum=14;">on the
- forums</a> at InteractiveTools.com. There you should also find the
- latest news.</p>
-
- <p>Sometimes I post news about the latest developments on <a
- href="http://students.infoiasi.ro/~mishoo/">my personal homepage</a>.</p>
-
- <h2>"It doesn't work, what's wrong?"</h2>
-
- <p>If it doesn't work, you have several options:</p>
-
- <ul>
-
- <li>Post a message to the forum. Describe your problem in as much
- detail as possible. Include errors you might find in the JavaScript
- console (if you are a Mozilla user), or errors displayed by IE (though
- they're most of the times useless).</li>
-
- <li>If you're positive that you discovered a bug in HTMLArea then feel
- free to fill a bug report in our bug system. If you have the time you
- should check to see if a similar bug was reported or not; it might be
- fixed already in the CVS ;-) If you're positive that a similar bug was
- not yet reported, do fill a bug report and please include as much
- detail as possible, such as your browser, OS, errors from JavaScript
- console, etc.</li>
-
- <li>If you want a new feature to be implemented, post it on the
- features request and someone will hopefully take care of it.</li>
-
- </ul>
-
- <p>You can <a href="mailto:mishoo@infoiasi.ro">contact me directly</a>
- <em>only</em> if you want to pay me for implementing custom features to
- HTMLArea. If you want to sponsor these features (that is, allow them to
- get back into the public HTMLArea distribution) I'll be cheaper. ;-)</p>

- * likely that you will have problems upgrading HTMLArea.
- *
- * Example on how to add a custom button when you construct the HTMLArea:
- *
- * var editor = new HTMLArea("your_text_area_id");
- * var cfg = editor.config; // this is the default configuration
- * cfg.btnList["my-hilite"] =
- * [ function(editor) { editor.surroundHTML('<span style="background:yellow">', '</span>'); }, // action
- * "Highlight selection", // tooltip
- * "my_hilite.gif", // image
- * false // disabled in text mode
- * ];
- * cfg.toolbar.push(["linebreak", "my-hilite"]); // add the new button to the toolbar
- *
- * An alternate (also more convenient and recommended) way to
- * accomplish this is to use the registerButton function below.

- *
- * Example on how to add a custom button when you construct the HTMLArea:
- *
- * var editor = new HTMLArea("your_text_area_id");
- * var cfg = editor.config; // this is the default configuration
- * cfg.btnList["my-hilite"] =
- * [ function(editor) { editor.surroundHTML('<span style="background:yellow">', '</span>'); }, // action
- * "Highlight selection", // tooltip
- * "my_hilite.gif", // image
- * false // disabled in text mode
- * ];
- * cfg.toolbar.push(["linebreak", "my-hilite"]); // add the new button to the toolbar
- *
- * An alternate (also more convenient and recommended) way to
- * accomplish this is to use the registerButton function below.
