It's complete: simple actions or configurable actions for database access, advanced routing features, wizard for Lazarus, support for i18n, high compatibility with JSON structures, easy and elegant REST implementation, plugins etc...
Carik is lightweight bot engine, simple, fast and open source. NLP has been provided in Indonesian as an example. Can run on microservice environments like Amazon Lambda also. Currently, Carik works on several messenger platforms such as Telegram, Facebook Messenger, Line, Direct Message, and Whatsapp. Carik is very easy to integrate with other systems, such as finance, staffing, iot and so forth.
Extended Man/XML Frames
Extended Components are a set of data and ini customized components. It contains relationships management components to use with your data software and for VirtualDbTreeEx. There are also invisible components for pictures' translation, extracting and copying. There is also an update component with its ini creating project. With Extended you can create reports quickly from data, Virtual Trees or tdbgrids. Extended uses GPL license. Source
Man Frames are management components for tables. Some data or property forms can manage some kinds of Datasets. It contains an old asynchronous data pull on customform and groupview. A prepared software with user management and functions management lets you quickly create a management software with an engine, without creating source. It depends on Extended components.
See also ATExtendedDialogs for a form which mimics the good features from the GTK2/Win32 font dialogs.
Old ExtPascal is an Ext JS wrapper that lets you use the Ext JS from Object Pascal commands issued by the server using FastCGI or FastCGI thru CGI gateway. That brings the structure and strict syntax of the Object Pascal for programming the web browser. It can be found here, here and here (Community).
Eye-Candy Controls - set of visual controls written for Lazarus. More than twenty advanced controls.
FastPlaz is a lightweight web framework that builds with Free Pascal. Have a wizard to build a Rich Web Application or Rest JSON API. FastPlaz working on Linux, Windows, and Mac. FastPlaz have internal ORM so that will makes it easy to access the database.
FastPlaz can run on shared hosting or even in microservice environments like Amazon Lambda.
View report at design time. Available for Lazarus from here.
fpctwit is a plurk, Twitter and OAuthv1 library with example programs (console and GUI). It's a framework that implements the Oauthv1 authorization protocol. The OAuth library (and the Twitter and plurk libraries using that) uses the Synapse network units for easy communication, but can easily be adapted for other network layers. It supports OAuthv1 secure authentication and SSL/TLS encryption. The library uses modified fpJSON units to allow getting UTF8 data out of the JSON data with Tweets returned from Twitter (for FPC trunk, the FPC units are used as Michael Van Canneyt added support for UTF8 in trunk).
Functionality includes: getting tweets using the Search API, tweeting, getting username info, authenticating using PIN/OOB or preset credentials (consumerkey+secret,authtoken+secret). The twitter console demo, fpctwit, also demonstrates the Streaming API to process and show Tweets and deletion messages. There is a plurk console demo that demonstrates the functionality in the plurk library.
Greyhound is a tiny ORM-ish for Free Pascal. It is fast, clean and simple to use.
Mattias Gaertner's gtk2forpascal project is developing the bindings for pascal to use the gtk2 libraries (gimp tool kit). Supported Languages are Free Pascal and Kylix and the bindings are intended to work under Linux, FreeBSD and Win32. These bindings are now also part of the packages supplied with fpc.
Habari ActiveMQ Client / Habari OpenMQ Client
Habari ActiveMQ Client is a library (and components) for Delphi(tm) 6 to 2009 and Free Pascal which provides easy access to Apache ActiveMQ, the most popular and powerful open source Message Broker. With Habari ActiveMQ Client, applications can connect to Apache ActiveMQ servers, subscribe to queues and topics, send and receive messages and objects, and work with transactions. The library follows the specification of the JMS API for Message Oriented Middleware. The communication layer supports Synapse and Internet Direct (Indy) for Lazarus.
Habari OpenMQ Client is a library for Delphi(tm) 6 to 2009 and Free Pascal which provides easy access to the Open Message Queue (OpenMQ) Message Broker, a very compact, fast and easy to use message queue system. OpenMQ is part of the GlassFish(tm) application server for the Java(tm) platform. The library follows the specification of the JMS API for Message Oriented Middleware. The communication layer supports Synapse and Internet Direct (Indy) for Lazarus.
The Internet Tools are a set of units, which should contain everything you need to interact with the www. Includes html parsers with a sax and dom-like interfaces, an XPath 2 / XQuery interpreter, CSS 3 selectors, pattern-matching xml templates, and a http/s connection wrapper around synapse/wininet. Compare the examples here.
KControls is a set of powerful components for Delphi and Lazarus. Main components are: KGrid/KDbGrid - grid components, KMemo - rich edit component, KHexEditor - hexadecimal editor. Freeware with source.
Laz Auto Updater is a visual drop-in component for the Lazarus/FPC IDE to make updating your application easier and simpler. It is aimed at Lazarus Windows developers who host their project in SourceForge.
- Drop-in the component, set one property (your sourceforge project name) and call these simple methods:
If LazAutoUpdate.NewVersionAvailable then... LazAutoUpdate.DownloadNewVersion LazAutoUpdate.UpdateToNewVersion
- ..and in your form.activate code:
- You (the developer) have plenty of control over how the component behaves, yet it is simple to use.
- End-users see the updating process as simple and transparent
Lazbro is an HTML viewer component which is 100% Lazarus based.
LazTermUtils is a small library contains a few classes for managing terminal I/O using ANSI escape sequences. The goal of this unit is provide the functionality provided by the CRT unit (and some more), but optimized for only the most prevalent systems, by only using escape sequences. It was tested under Windows 10 and Linux and allows for writing portable, pretty console applications on both systems.
priyatna.org is a set of cool Delphi components ported to Lazarus. Components: ButtonBar, NiceChart, NiceGallery, NiceGrid, NicePreview, NiceSideBar and SortListView.
The PUMA Repository (Pascal Units for Medical Applications) is a collection of Pascal units for health informatics. It is compatible with a range of Pascal dialects including Lazarus / Free Pascal, Delphi and winsoft Pocket Studio.
QRCodeGenLib4Pascal is a Delphi/FPC compatible library that provides an easy to use interface for generating QR Codes, from text strings and byte arrays.
The Synapse Project by Lukas Gebauer provides a serial port and synchronous TCP/IP Library.
Library for serial communication (Linux, Windows) from the author of Synapse. Homepage (same as Synapse)
A lot of useful Lazarus/FPC related information and components can be found on Tony Maro's Icebox site (archived link). His TMPack (archived download link), Checkbook Tracker and RDP Frontend application (archived download link) are all excellent examples of the quality components and applications that Lazarus is capable of producing.
The Light Pascal Toolkit (LPTK)
TML Messaging Suite
TML Messaging Suite 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. Available as binary packages for Windows 32/64, FreeBSD, macOS and Linux.
TRURL RPN Engine
The RPN Engine of the TRURL project is a free library that may be used as a foundation for virtual calculators with Reversed Polish Notation (RPN). Precompiled demo applications are available.
The tree list view is the combination of a TTreeView and a TListView, i.e. a tree with columns. It is custom drawn and therefore completely platform independent. (Windows, Linux gtk2, 32/64bit. Didn't test mac/qt through)
VirtualDbTreeEx is a selection interface entirely made with data.
ZenGL is an open source library with tools, which helps to develop games and interactive application for different platforms.
