gtklean is a C header file generated directly from the GTK+ headers to provide a visually cleaner and less error prone C API for GTK+. It eliminates gtk_ prefixes in front of every GTK+ function. It automatically inserts calls to the type checking and casting macros for arguments that require them (e.g. GTK_WIDGET() and GTK_SIGNAL_FUNC()) so you can't forget them and never need to see them. It also replaces the string literals used for signal names with C identifiers to replace run time errors with compile time errors.
DbDesigner is a useful tool for constructing databases in an intuitive and easy-to-use environment, where you have a visual representation of the tables and relations contained in your project. You can quickly see the fields in a table or how each table relates to the others. After you are finished, it can export the schema of the database into an .sql script, or directly connect to a database backend and build it there. It can also import already existing databases from .sql scripts or db backends. It can save your project into its native format (XML) so all information is kept, and it has a plugin architecture to be easily extensible to work with many database servers (it comes with 2 plugins for PostgreSQL and MySQL).
UIML stands for User Interface Markup Language. It is an XML-family language for user interface description. The basic idea is to build user interfaces for various platforms from one description (source). The description consists of a widget structure definition, widget properties, reaction on events, widget set description, application logic, etc. The project aim is to build a Python renderer for UIML. It supports static rendering and wxPython. See additional info on UIML at www.UIML.org
The JET Code Generator connects to any JDBC-based database and exports the schema as an XML-formatted file, and then generates code based on XSL Transformations. The user is free to write/modify XSLTs to generate virtually any type of source code from the XML representing your database schema. A complete example is included with a database, support classes, XSL Transformations, and build scripts (ANT and batch).
Parse::Yapp provides a set of modules and a frontend to generate Perl OO LALR(1) parsers. It can input clean yacc or bison grammars. The generated parsers are fast, being based, like yacc, on building Deterministic Finite Automata (DFA) and moving through a set of states using Deterministic Push Down Automata (DPDA) derived from the DFA to match the input stream tokens.
UniT is a general purpose text generator written in and with full access to Java. It can be used to generate any text of any format, including program code of any programming language (Java, C, C++, SQL, etc.), or documentation of any format (HTML, XML, RTF, LaTex, etc.). It is similar to JSP, but easier, more general, and more flexible. With an appropriate parser (XML-Parser, like DOM), UniT can also be used to convert text documents.
