# Awesome Pascal [](https://awesome.re)
A curated list of awesome Delphi, FreePascal and other *Pascal frameworks, libraries, resources, and shiny things. Inspired by awesome-xxx stuff.
**Note that only open-source projects are considered. Dead projects (not updated for 3 years or more) must be really awesome or unique to be included.**
Feel free to suggest other missing nice projects either by comments or pull requests.
:exclamation: **Note on compiler compatibility**. There are compiler/language dialect compatibility badges for all projects based on a project's description. No real compatibility with compilers not officially supported is checked. Often a code could be used with non-supported compiler/language dialect with minor modifications but there could be exceptions.
:exclamation: **Note on features contained in big projects**. There are plenty of big projects in the list that contain many features deserving to be noted in the corresponding sections. For example, a HTTP server could have JSON parser, logger, command line parser, DB access classes and so on. For really big code base duplicated entry in specific sections is allowed linking to a section with main description. However to reduce duplication additional features are more usually listed in comments. So if you're looking for some feature don't forget to search by key words through the whole list in additon to inspecting the corresponding section. Also feel free to suggest additions of available features in big projects to help others find what they want.

## General Libraries ##
*Big general-purpose libraries*
* [JCL](https://github.com/project-jedi/jcl). `[Delphi]` `[FPC]` Set of thoroughly tested and fully documented utility functions and non-visual classes which can be instantly reused in your Delphi and C++ Builder projects. The library is grouped into several categories such as Strings, Files and I/O, Security, Math and many, many more.
* [JVCL](https://github.com/project-jedi/jvcl). `[Delphi]` Library of over 600 Delphi components developed by "Project JEDI" members.
// *GUI, algorithms, classes, API headers etc.*
* [Alcinoe](http://sourceforge.net/projects/alcinoe) ([mirror at GH](https://github.com/Zeus64/alcinoe)). `[Delphi]` Library of visual and non-visual components 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; opengl video player; FireMonkey controls; Other: Self-Balancing Binary Trees, expression evaluator*
* [Fundamentals Code Library](http://sourceforge.net/projects/fundementals) (abandoned, more recent fork is [here](https://github.com/fundamentalslib/fundamentals4) - though it slightly differs in units set, f.ex. no XML. Recent major version 5 [here](https://github.com/fundamentalslib/fundamentals5)). `[Delphi]` `[FPC]` Collection of Delphi / FreePascal code units. Includes libraries for Unicode, Strings, Data Structures, Sockets and Mathematics.
// *Utils: ZLIB compression; JSON; XML; ProtocolBuffers; Unicode routines; data structures; Hashes: XOR, CRC, Adler, MD5, SHA, secure keyed MD5/SHA, etc; Network: blocking TCP client/server, HTTP(S) via SSL3/TLS1.0/TLS1.1/TLS1.2 (fully native); SQL parser; BitCoin MtGox client; Blaise script engine; Cipher: AES, DES, FUNE, RC2, RC4, RSA, Diffie-Hellman; Maths: matrix, complex, statistics, huge numbers*
* [Spring4D](https://bitbucket.org/sglienke/spring4d). `[Delphi]` Open-source code library for Embarcadero Delphi 2010 and higher. It consists of a number of different modules that contain a base class library (common types, interface based collection types, reflection extensions) and a dependency injection framework. Includes Encryption Library.
// *Collections and other containers using Generics and based on IEnumerable, probably more accurate and featured than RTL analogs; crypto: CRC, DES, MD5, SHA; file utils etc*
* [TheUnknownOnes](https://github.com/chaosben/theunknownones). `[Delphi]` Huge heap of classes, components, utilities for almost every purpose. Nearly undocumented and seems not very up-to-date though.
* [CNVCL](https://github.com/cnpack/cnvcl). `[Delphi]` CnPack Component Package. Large collection of visual components, classes and utilities. // *Lots of useful stuff; documentation and comments mainly in Chinese*
* [mORMot](https://github.com/synopse/mORMot). `[Delphi]` `[FPC]` Client-Server ORM/ODM SOA MVC framework for Delphi 6 and higher, or FPC 2.7. Direct SQL/NoSQL database access, ORM/ODM over objects, RESTful ORM and SOA services via interfaces over high performance HTTP server, MVC/MVVM web sites, testing including mocks and stubs, logging, cryptography, compression, command line parser, threading, service/daemon support; huge documentation.
* [MARS - Curiosity](https://github.com/andrea-magni/MARS). `[Delphi]` Delphi REST Library. Pure REST approach, standard concepts in a familiar Delphi flavor (including a component based client library). Known compatibility: Delphi versions from XE to 10 Seattle. Some functionalities requires FireDAC.
* [ADAPT](https://github.com/LaKraven/ADAPT). `[Delphi]` Advanced Developer Async Programming Toolkit, foundation library intended to be used at the heart of your projects for the purpose of providing extremely powerful, multi-threaded (and thread-safe) capabilities. Event Engine - a very powerful system for producing Multi-Threaded, Asynchronous and Event-Driven programs. Generics Collections - highly efficient Collection Types (Lists, Trees, Maps etc.). Math Library - a library for Unit Conversion, special calculation and other useful mathematics routines. Package Engine - extension of the Streamables Engine supporting the packaging of files together (a VFS of sorts). Shared Streams Library - 100% Thread-Safe Stream Classes (Interfaced too) allowing read/write from multiple Threads. Stream Handling Library - makes working with Streams much easier! Handles Deleting, Inserting, Reading and Writing data.
* [Redux Delphi](https://github.com/pierrejean-coudert/ReduxDelphi). `[Delphi]` Predictable state container for Delphi apps utilizing a unidirectional data flow. Inspired by ReduxJS. Comes with Immutable Generic List.
* [GrijjyFoundation](https://github.com/grijjy/GrijjyFoundation). `[Delphi]` Foundation classes and utilities that are used throughout the other Grijjy Repositories.
// *BSON/JSON, IOCP/EPOLL sockets, socket pools, HTTP, HTTP/2, OpenSSL, ProtocolBuffers.*
* [unRxLib](http://www.micrel.cz/RxLib/dfiles.htm). `[Delphi]` Effort to keep RxLibrary (library of 60+ components) actual.
* [QuickLib](https://github.com/exilon/QuickLib). `[Delphi]` `[FPC]` Quick development library (AutoMapper, LinQ, IOC Dependency Injection, MemoryCache, Scheduled tasks, Config, Serializers, Json Serialize, Chronometer, Threads, Lists, Config, Console services etc) with crossplatform support for Delphi/Firemonkey (Windows,Linux,macOS/IOS/Android) and freepascal (Windows/Linux).
