Word stemming is usually applied to query and search systems. It enables them to return related results with similar meaning but slightly different spelling. As an example, the English stemmer returns “write” for “write”, “writes”, “writing”, and “writings”.

YuPdf includes the following functionality:

Create PDF documents containing text, graphics, and bitmap images.
Easily add outlines, annotations, and document attachments.
Embed JPEG and PNG images, preserving transparency.
Embed Type 1 and TrueType fonts.
Document and image compression and encryption.
Character set and encoding support (1- and 2-byte UTF-8, ISO 8859-1 to 8859-16, Windows 1250 to 1258, KOI8-R).
CJK fonts and encodings for Chinese and Japanese text.
Object wrapper classes for simplified coding.
Extensive number of demo projects to get started.
No dependencies, does not require DLLs or external files.

YuPcre2 is a library of Delphi components and procedures that implement regular expression pattern matching using the same syntax and semantics as Perl, with just a few differences. There are two matching algorithms, the standard Perl and alternative DFA algorithm:

The Perl algorithm is what you are used to from Perl and j@vascript. It is fast and supports the complete pattern syntax. You will likely be using it most of the time.
DFA is a special purpose algorithm. If finds all possible matches and, in particular, it finds the longest. It never backtracks and supports partial matching better, in particular multi-segment matching of very long subject strings.

YuOpenSSL is the only OpenSSL implementation for Delphi which does not require OpenSSL DLLs. YuOpenSSL enables Delphi applications to compile encryption and Internet security into a single executable with no dependencies. This ensures complete control about the OpenSSL version and ends all worries about DLL deployment and locations.

HTML Parser and Tree Builder
Parse HTML, good and bad.
HTML5 tokeniser with SAX-style events.
Flexible tree builder API for custom DOM implementations.
Readily provided HTML5 parser classes convert HTML documents into DOM trees:
Simple DOM tree: Fast and efficient.
LibXml2 tree: Fully compatible with LibXml2 functions, including XPATH and LibXslt transformation.
XDOM tree: Feasability study limited by XDOM restrictions.
Fast, efficient, and low memory usage.

DIZipWriter is a Delphi component to create PKZip-compatible ZIP archives. Archive output is based on TStream and writes directlyfiles (TFileStream), memory (TMemoryStream), or database BLOBs (TBlobStream).

DIXml is an embedded XML, XSLT, and EXSLT processing library for Delphi (Embarcadero / CodeGear / Borland). It is build on the libxml2, libxslt and libexslt libraries. However, DIXml requires no DLLs or any other external files whatsoever. All required code is compiled completely into the application's executable. DIXml is the most feature-complete XML and XSLT solution for Delphi.

DIUnicode's Pascal implementation features more than 70 encodings, like UTF-7, UTF-8, UTF-16, the ISO-8859 family, various Windows and Macintosh codepages, KOI8 character sets, Chinese GB18030, and more. Adding a new character coding is as simple as writing a single conversion procedure. It supports 144 character sets and encodings when linked against DIConverters.

DITidy is build on the libtidy library but requires no DLLs not other external files. All code is compiled into the application's executable.
