The original miniGlue is aimed to make a light-weighted Photoshop-style layer management system. We want to make the code as easy as possible, easy to understand. We hope everybody could build his/her own layer-based image processing software on the fly with miniGlue. Then another founder of miniGlue, x2nie, made a bigger vision that miniGlue stands of ready to use visual-components for very fast and easily develop graphic editor under Delphi/Lazarus. It also extendable to your own need.

THTMLdom is a (Delphi) class with functions to read a HTML source file and dissect it into a tree of THTMLelement. The attributes of the HTML tags are stored in the elements. Functions are provided to select elements on the basis of the attribute values or tag names. The structure of the tree can be shown and it can be rendered as plain text. The source is plain Delphi pascal, requiring a version that supports Tdictionary. There is no dependency on 3rd party units. The file to be parsed must have valid HTML4/5 tags. It is not necessary that the HTML is ‘correct’ in the sense that end tags may be wrongly placed or be absent altogether. The speed of processing (reading+parsing) is formidable: 15-40 msec per Mbyte or around 1 msec per 1000 HTML tags.
. Delphi Lightweight, language-independent software stack for point-to-point RPC implementation. Thrift provides clean abstractions and implementations for data transport, data serialization, and application level processing. The code generation system takes a simple definition language as input and generates code across programming languages that uses the abstracted stack to build interoperable RPC clients and servers. Thrift makes it easy for programs written in different programming languages to share data and call remote procedures. With support for 28 programming languages, chances are Thrift supports the languages that you currently use.

Code to process human readable input is often highly stylized and repetitive. This project extracts the common elements found in such code and makes them available in a concise form as C tables and subroutines.
Establishing asynchronous, multithreaded, bidirectional communication without blocking messages can be time consuming and error prone. Using libTML allows you to implement asynchronous message exchange on top of the IETF standard protocol BEEP (Blocks Extensible Exchange Protocol) without the need to fiddle around with the basics of message processing. All your work can be put into the features of the application instead of taming a TCP/IP socket.
UMDS is small, strong and expansible project. The model offers a uniform method of conceptual view of the diverse data as a sequence of bits and a uniform method of keeping and processing this sequence on the external storage.
Zorba is a general purpose XQuery processor implementing in C++ the W3C family of specifications. It is not an XML database. The query processor has been designed to be embeddable in a variety of environments such as other programming languages extended with XML processing capabilities, browsers, database servers, XML message dispatchers, or smartphones. Its architecture employes a modular design, which allows customizing the Zorba query processor to the environment’s needs. In particular the architecture of the query processor allows a pluggable XML store (e.g. main memory, DOM stores, persis
