Open Source C Search Software

Write programs as graphical dataflow charts instead of text. Compile them to any programming language you want. Besides this project includes the most efficient tree-based sorting algorithm that is possible. Originally developed on a CTOS Color NGEN, at first in Pascal, later ported to C, finally - 20 years later - ported to Linux. Currently it's still not really system independent. But it's intended that further releases will cure this.

DFA library is a regular expression library capable of the classic RE syntax (i.e. - without any perl extension). Unlike many other libraries with similar functionality, a deterministic finite automata (DFA) is used. DFA was formerly called npcre, wh

This project considers the problem of calculating primes as a sorting problem. It includes the most efficient tree-based sorting algorithm that is possible and shows that finding a new prime can be done by sorting the differences between the previous primes in the right way. Unfortunately it has turned out that going this way is even more slowly than trying to find primes by brute force. So it can only be used as a test with heavy load for the sorting algorithm, which can be used for sorting any kind of data. And as already mentioned, it's just the most efficient tree-based sorting algorithm that you can get. But furthermore this way of finding primes interestingly leaves a hard nut to crack for mathematicians: In very rare cases it finds numbers that are not primes. For all primes below one million this phenomenon arises in exactly two cases: 31213 which is 7 * 7 * 7 * 7 * 13 336141 which is 3 * 3 * 13 * 13 * 13 * 17 Who can explain, why?

This project is a tool to detect file types by signatures and mime types. It uses hash tables to make the detection of a file type as fast as possible. The signature and mime types lists are stored at simple user-friendly files. This file type detector supports a lot of formats (image, archive, text, documents, audio, video, fonts and others). It also includes Microsoft OLE compound file types. The detector's algorythm has special features to detect text file types like (HTML, XML, JSON, etc.) and text file UNICODE charsets by using their BOMs (Byte order marks). Its small simple interface can be used at the most popular platforms.

The "Lib45" string search library provides routines that generate fast string searching code at run-time. The library is written in Assembly language for Intel 32bit CPUs.

PileWorks provides the organizational structure for coordinating several different projects which approach some aspect of Pile Technology. PileWorks defines a set of interfaces and implements some basic infrastructure for Pile engines and agents.

This program searches for both dynamic and static libraries, looking those ones which provide given object symbols. It will assist you in undefined symbol errors eliminating.
