Xataface is a flexible and shapable skin that sits on top of MySQL, making it accessible to every-day users. It automatically generates the appropriate forms, lists, and menus for a user to interact with the database without having to know any SQL. It is a full-featured Web application framework, and gives developers the flexibility to customize the features and behavior of their application via configuration files (using the simple INI-file syntax), templates, and plug-ins. A generic application with no customizations is completely functional, but the developer is free to customize things at his leisure.
The libmba package is a collection of mostly independent C modules potentially useful to any project. There are the usual ADTs including a linkedlist, hashmap, pool, stack, and varray, a flexible memory allocator, CSV parser, path canonicalization routine, I18N text abstraction, configuration file module, portable semaphores, condition variables, and more. The code is designed so that individual modules can be integrated into existing codebases rather than requiring the user to commit to the entire library. The code has no typedefs, few comments, and extensive man pages and HTML documentation.
itools is a collection of Python libraries which provides a wide range of capabilities, including an abstraction over directory and file resources, a search engine, type marshallers, datatype schemas, i18n support, URI handlers, a Web programming interface, a workflow interface, and support for data formats such as (X)HTML, XML, iCalendar, RSS 2.0, and XLIFF.
libunibreak is an implementation of the line breaking and word breaking algorithms as described in Unicode Standard Annex 14 and Unicode Standard Annex 29. It is a superset of, and supersedes, liblinebreak. It is designed to be used in a generic text renderer. FBReader is one real-world example.
libintl-perl is a library that supports message translation for Perl, written in pure Perl (version 5.004 or better). A faster C version is also built and installed if the system fulfills all requirements. Its interface is a superset of the gettext family of functions in C, and it uses the same file formats as GNU gettext, making it possible to use all tools available for gettext itself and to seamlessly integrate internationalized Perl code into mixed-language projects.
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.
cpdetector is a small yet clever framework for codepage detection that integrates different strategies. It may be used as a library for third party software that accesses textual data over network. It also includes a best-practice implementation in form of a command line tool that allows sorting and transforming large collections of documents based on their codepage. Available strategies include: jchardet (exclusion, frequency analysis, and guessing), detection of the HTML charset property, and detection of the XML encoding declaration.
