How to add a new dictionary to aspell
- Download the dictionary from ftp.gnu.org/gnu/aspell/dict
- Extract it from the tar file in a zimbra work directory
- Set Zimbra's aspell in the path in /opt/zimbra/.bashrc with:
- PATH=/opt/zimbra/aspell-0.60.3/bin:$PATH
- Change your login to "zimbra" (su zimbra)
- Configure and install the dictionary according to the README
- ./configure
- make
- make install
- Verify the datadir and dictdir it must be /opt/zimbra/aspell-0.60.6/lib/aspell-0.60
- Edit the file /opt/zimbra/httpd/htdocs/aspell.php to reference the new dictionary. For example to add the french dictionary:
- $dictionary = pspell_new("en_EN");
- TO
- $dictionary = pspell_new("fr_FR");
NOTE: I think is better to change the value of the variable $locale at the start of the file.
NOTE (fr): Read the README on the dict source directory to choice the right setup (fr_FR-40, fr_FR-60, etc)
NOTE: If you are using a non-english based language with special chars like tildes (spanish, for example), you have to modify aspell.php
This file is located at /opt/zimbra/httpd/htdocs/aspell.php. Replace this block (line 82 or so)
$suggestions = implode(",", pspell_suggest($dictionary, $word)); $misspelled .= "$word:$suggestions\n";
with this one:
$suggestions = implode(",", pspell_suggest($dictionary, $word)); $suggestions=iconv("iso-8859-1","UTF-8",$suggestions); $misspelled .= "$word:$suggestions\n";
NOTE: After changing the aspell language restart the spellchecker as the user zimbra with the following command:
zmspellctl stop; zmspellctl start
There is also a problem when splitting words. Replace (line 48 or so)
$words = preg_split('/[^\w\'-] /', $text);
with this one:
$words = preg_split('/[^\w\'\xc0-\xfd-]+/', $text);
This regexp line should be enough for most western Europe languages (Spanish, French, German, Portuguese and Italian). It includes all ISO8859 europeean letters in the range 192-253 of the table below.
- To add a set of custom words see this How-To
Adding Latin-2 dictionary support
Many aspell dictionaries do not use UTF-8 encoding while UTF-8 is encoding of a choice for Zimbra suite. This means that text should be converted from UTF-8 to ISO-8859-x, spell checked ant then misspeled and sugested word should be translated back to UTF-8 for browser display. The following patch shows (Slovenian) modifications to Zimbra 4.5.9 spelling processor:
