Pascal Awesome

Delphi / Lazarus / FPC

General Libraries

• JVCL. Library of over 600 Delphi components developed by "Project JEDI" members. // GUI, algorithms, classes, API headers etc.
• Alcinoe. Components suite for Delphi. // Network: FTP/Http/NNTP/POP3/SMTP, ISAPI, WinInet Http/FTP clients; DB: Firebird/MySQL/SQLite3/Memcached/MongoDb/SphinxQL; XML/JSON Parser; ZLIB; Cryptography: AES, Blowfish, MD5, SHA, secure keyed MD5/SHA; Other: Self-Balancing Binary Trees, expression evaluator

Includes libraries for Unicode, Strings, Data Structures, Sockets and Mathematics. // Utils: ZLIB compression; JSON; XML; ProtocolBuffers; Hashes: XOR, CRC, Adler, MD5, SHA, secure keyed MD5/SHA, etc; Network: bYou must click thanks to see this content... optional support).
• TForge. Open-source crypto library written in Delphi, compatible with Free Pascal Compiler. MD5, SHA1, SHA256, CRC32, Jenkins-One-At-Time, HMAC, PBKDF1, PBKDF2, AES, DES, RC4, RC5, Salsa20.

XML/JSON

• OmniXML. XML parser written in Delphi. Full support for Document Object Model (DOM) Level 1 specification; Supports Extensible Markup Language (XML) 1.0 (Second Edition) specification; Has built-in support for different code pages (main 8-bit code pages, UTF-8, UTF-16); Is compatible with MS XML parser; Fast parsing even large and highly structured documents; Includes helper functions to ease processing XML documents; Simplified XPath support.

• SAX for Pascal. Designed to implement the Simple API for XML Parsing in Pascal/Delphi. //Callback-based XML parser, useful for processing huge XML streams.

• KDS XML. Class library for streamed parsing, validating and generating XML. It is written in Object Pascal/Delphi and works on Win32 (Delphi) and Linux (Kylix). Parts of it depend on the SAX for Pascal interface specifications.

• XML Partner. Helps add the power of XML to Borland Delphi, C++ Builder, and Kylix projects through native, easy to use VCL and CLX components. These powerful components simplify the process of creating, modifying, and parsing XML data documents. // Seems dead, check out thispage for probably newer version.

• Open XML. Provides a wide range of methods, components and foundation classes. It can be used for Win32/Kylix as well as for .NET development.

• SuperObject. Parser/writer for JSON data format. This toolkit is designed to work with Delphi and FreePascal (win32, win64, linux32, linux64, MacOSX Intel)

• OXml. New XML library for Delphi and Lazarus, developed in late 2013. I took some inspiration from OmniXML but wrote the library completely from scratch. The aim of OXml is to be the most versatile and fastest XML library for the Pascal language. OXml features a SAX parser, DOM implementation, a sequential DOM parser a direct XML reader/writer and a vendor for Delphi's XmlIntf.TXMLDocument. OXml supports all Delphi versions starting from Delphi 4 on all platforms: Win32, Win64, OSX, iOS, Android. OXml supports Lazarus 1.0 and newer on all platforms (tested Win32, Win64, Linux, MacOSX).

• Libxml2 for pascal. Pascal units accessing the popular XML API from Daniel Veillard. This should be usable at least from Kylix and Delphi, but hopefully also from other Pascal compilers (like freepascal).

• NativeXml. This component contains a small-footprint Object Pascal (Delphi) XML implementation that allows to read and write XML documents. You basically only need one unit and you can simply add it to the "uses" clause. You can use this software to read XML documents from files, streams or strings. The load routine generates events that can be used to display load progress on the fly. You can also use it to create and save XML documents.

• Chimera. Open Source (MIT License) library for Delphi XE2 which provides a fast and cross platform JSON generator/parser (serializer/deserializer) under a license that doesn't suck.

• SynCommons. High speed JSON library, using 

  Code:

  TDocVariant (custom variant type for storage and access)

• SynCrossPlatformJSON. High speed cross-platform JSON library, using 

  Code:

  TDocVariant (custom variant type for storage and access)

LanguageTools for Pascal and other languages

• Next Delphi Yacc & Lex. Parser generator toolset for Delphi.
• Abstract Syntax Tree Builder. With DelphiAST you can take real Delphi code and get an abstract syntax tree. One unit at time and without a symbol table though.
• Castalia-Delphi-Parser. These files make up a hand-written high speed parser for the Object Pascal dialect known as "Delphi". The original work was done by Martin Waldenburg in the late 1990s, and the project was abandoned sometime before 2003, when I found the code and began working on it. I have kept it updated as necessary to work with my project, called "Castalia".

SystemLow-level helper stuff: memory, threading etc

• FastMM. Lightning fast replacement memory manager for Embarcadero Delphi Win32 and Win64 applications that is not prone to memory fragmentation, and supports shared memory without the use of external .DLL files. // Used as stock memory manager since 2006 but in simplified version. Provides powerful memory leak/corruption detection instruments.
• OmniThreadLibrary. Simple to use threading library for Delphi. // Easy integration of async processes in your app
• ScaleMM. Fast scaling memory manager for Delphi
• Delphi Detours Library. Library allowing you to hook Delphi functions and object methods and Windows API functions. It provides an easy way to insert and remove hook. // Supports x64, calling original functions, multi hooks, COM/Interfaces/win32api, object methods hooking, fully thread-safe, Delphi 7/2005-2010/XE-XE7 & Lazarus/FPC, 64 bit address is supported.
• MemoryModule. With the MemoryModule engine you can store all required DLLs inside your binary to keep it standalone. Additional hook units allow transparent using of MM engine thus allowing switching MM/WinAPI loading as well as enabling 3rd party dynamic-load DLL interfaces that are unaware of MM (tested with Interbase Express components and Firebird client library). MemoryModule is a Pascal port of Joachim Bauch's C MemoryModule.

Other non-visual

• TRegExpr. Easy to use and powerful tool for sophisticated search and substitutioning and for template-based text input check. // Abandoned since 2004 but unlike stock RAD Studio implementation doesn't use PCRE obj files that add dependency on msvcrt.dll
• FLRE. FLRE ( F ast L ight R egular E xpressions) is a fast, safe and efficient regular expression library, which is implemented in Object Pascal (Delphi and Free Pascal) but which is even usable from other languages like C/C++ and so on.
• OnGuard (Alternate and maintained version for recent compiler version only). Library to create demo versions of your Borland Delphi & C++Builder applications. Create demo versions that are time-limited, feature-limited, limited to a certain number of uses, or limited to a certain # of concurrent network users. // Second link points to an adapted version for newest compiler versions.
• StringSimilarity. Package designed for some fuzzy and phonetic string comparison algorithms. So far implemented are the following algorithms: DamerauLevenshtein, Koelner Phonetik, SoundEx, Metaphone, DoubleMetaphone, NGram, Dice, JaroWinkler, NeedlemanWunch, SmithWatermanGotoh, MongeElkan.
• STOMP Client. STOMP client for Embarcadero Delphi and FreePascal. The project can use INDY (Delphi) or Synapse (Delphi or FreePascal).
• PubSub Chimera. Open Source (MIT License) library for Delphi which provides a fast and cross platform PubSub and Message Queue implementation under a license that doesn't suck.
• DuckDuckDelphi. Adds simple duck typing to Delphi Objects and provides an RTTI helper class to simplify many common RTTI tasks.
• byterage. Object pascal class library designed to remove some of the limitations of streams. The framework is very simple to use, with only one common ancestor class (TBRBuffer) which defines a set of storage agnostic mechanisms for allocating, scaling, inserting, deleting and otherwise manipulating a segment of raw binary data.
• stateless. Simple library for creating state machines in Delphi code.
