By default there is no spell check available in the Open-Xchange application itself because most of the modern browsers usually offer a spellcheck module. TinyMCE, the HTML editor which is used by Open-Xchange for HTML editing while writing an eMail, offers a wide set of functions and features which can be added to the HTML editor UI. This example will describe how you can enable the TinyMCE based spellcheck functionality within the Open-Xchange mail module.
Please note: Open-Xchange cannot support the spellcheck module itself and the according infrastructure (aspell, PHP), as those modules won't be maintained and tracked by Open-Xchange. On machines with lot of users this service may produce heavy load due to many request so we highly recommend to cluster it or, even better, to use the native spellcheck plugins of modern browsers.
Please visit the TinyMCE website and download the latest TinyMCE "PHP Spellchecker" plugin at http://www.tinymce.com/download/download.php (at the bottom of the list). This article uses Version 2.0.5.
Extract the downloaded archive and move the extracted directory "spellchecker" to the TinyMCE location on the Open-Xchange installation:
$ mv spellchecker /var/www/ox6/3rdparty/tinymce/jscripts/tiny_mce/plugins/.
This can be accomplished by adding a properties file to directory "/opt/open-xchange/etc/groupware/settings".
$ vim /opt/open-xchange/etc/groupware/settings/spellchecker.properties modules/mail/spellcheck=true
The spell check language for the tinyMCE spellcheck module defaults to english and is configured inside the files editor_plugin.js and editor_plugin_src.js located in the directory /var/www/ox6/3rdparty/tinymce/jscripts/tiny_mce/plugins/spellchecker. A '+' character in front of the language name will indicate that this will be the default language used for the spellchecker. The default value for this option is '+English=en'. You can change this to another language by moving the '+' character in front of the language name of your choice in both files. Search for 'spellchecker_languages' to easily jump to the languages section in these files. The changes are active immediately after you have cleared your browser cache.
Finally we need to tell the spellchecker module which binary it should execute in order to get spelling suggestions. By default GoogleSpell is activated for remote suggestion, but as this would mean that every eMail which should be checked will be send to Google, we recommend to use a local aspell instance for this purpose. To do so, install aspell and the according dictionaries as we told you in the requirements section, and modify /var/www/ox6/3rdparty/tinymce/jscripts/tiny_mce/plugins/spellchecker/config.php to specify the aspell binary location. Please use the following example, and just replace [REPLACE_WITH_PATH_TO_ASPELL_BIN] with the location of the aspell binary (for example /usr/bin/aspell):
<?php /** * config.php * * @package MCManager.includes */ // General settings //$config['general.engine'] = 'GoogleSpell'; //$config['general.engine'] = 'PSpell'; $config['general.engine'] = 'PSpellShell'; //$config['general.remote_rpc_url'] = 'http://some.other.site/some/url/rpc.php'; // PSpell settings $config['PSpell.mode'] = PSPELL_FAST; $config['PSpell.spelling'] = ""; $config['PSpell.jargon'] = ""; $config['PSpell.encoding'] = ""; // PSpellShell settings $config['PSpellShell.mode'] = PSPELL_FAST; $config['PSpellShell.aspell'] = '[REPLACE_WITH_PATH_TO_ASPELL_BIN]'; // e.g. /usr/bin/aspell $config['PSpellShell.tmp'] = '/tmp'; // Windows PSpellShell settings //$config['PSpellShell.aspell'] = '"c:\Program Files\Aspell\bin\aspell.exe"'; //$config['PSpellShell.tmp'] = 'c:/temp'; ?>
