Archetypes is a framework for developing new content types in Plone. The power of Archetypes is first in automatically generating forms, second in providing a library of stock field types, form widgets, and field validators, third in easily integrating custom fields, widgets, and validators, and fourth in automating transformations of rich content.
BabelKit is an interface to a universal multilingual database code table. It takes all of the programming work out of maintaining multiple database code definition sets in multiple languages. The code administration and translation page lets developers define new virtual code tables, new languages, enter all codes and their descriptions, and then translate them into all languages of interest. Perl and PHP classes retrieve the code descriptions and automatically generate HTML code selection elements in the user's language. This makes internationalization and localization of Web sites and database interfaces much easier.
Expose is a PHP template engine. It supports server and client-sided caching, a plugin system (to simplify common tasks like inserting a date picker) and internationalization (to write templates in multiple languages using external translation files). Unlike most template engines, Expose's template script language is based on PHP itself, which means you don't have to learn a new syntax. You can use most of the PHP language elements and functions in the way with which you're familiar.
GTK2 Text Editor is a simple Unicode text editor that supports many encodings. It works as a nice Notepad replacement, and can also be used as an encoding converter. It supports multi-level undo, right to left text (as in Hebrew), and other Unicode features. It can auto-close an XML/HTML tag. There is no syntax highlighting yet.
The Gettext PO format is used by translators to translate free software. The Vim Gettext PO syntax highlighter enhances the current Vim PO file highlighter. These enhancements include the inclusion of KDE-specific highlighting, error detection, and highlighting of new features of the PO format, including pluralisation.
I18N is a class that gets translation texts from flat files or from an SQL database. The system supports variables in translated strings and has a conversion facility to move data from one container to another. An included tool checks programs against sets of translated strings to detect references without strings or unused strings. Each call checks that referenced variables exist.
Konjugator helps with learning or interpreting verb forms in Welsh. It produces a list of around 200,000 inflected verb forms for almost 4,000 Welsh verbs, along with English glosses and parsing information. It attempts to conjugate Welsh verbs that are unknown to it, and will give parsing details for random Welsh verb forms if these are known to it.
Linguistico is a set of language tools based on the Italian language. It includes a dictionary, a thesaurus, word definitions, and other scripts and programs. You can use these tools with OpenOffice.org, Mozilla Thunderbird, Mozilla Firefox, MySpell, MyThes, Aspell, and HunSpell.
