FasmOnDelphi is a Free Pascal/Delphi library for using Flat Assembler in any OS (can use FASM.DLL on Windows). It is a cross platform (Flat Assembler can work only on i386 compatible platforms) library for using FASM in runtime. In contrast to Fasm4Delphi, it does not depend on operating system and bit type.
The package is available since Lazarus 1.5.
Fb_embedded2.pas is a Pascal unit that can be included in a Lazarus project to enable embedding of Firebird (version 2.0.3) database server (a.k.a. [http://en.wikipedia.org/wiki/DBMS DBMS]) into an .exe file, without need for distributing any DLL. The original code for Delphi was created by Fikret Hasovic and Samir Ribic, modified by Zlatko Matic ([mailto:matalab@gmail.com matalab@gmail.com]) for FPC/Lazarus.
The FCL-Base package contains a number of units that are either really "base" functionality or more misc stand-alone units.
For the ServiceManager unit inside fcl-extra, please see ServiceManager
FCL-Image started life as "fpimage", pretty much as an attempt to implement a generally portable TImage like class, without the deep win32 and VCL ties.
This package contains some useful units for dealing with Pascal source files: Parsing, creating structures in memory, and output to files.
fcl-res is a Free Component Library component that provides functionality to create and access all kinds of resources, including those on:
The package FCL-XML contains units that parse XML and HTML files to DOM, and can render the DOM tree to HTML, XHTML and XML.
Component for handling Recent files list and Open, Save, Save As, Exit Commands. Uses a ini file for the recent list.
Free Pascal doesn't provide built-in language support for Fixed-point type. However there are a number of fixed point maths libraries available.

The original Freetype 1 font library had a version written in Pascal and compilable with old versions of FPC. This version was downloaded from http://cvsweb.xfree86.org/cvsweb/xc/extras/FreeType/pascal/lib/Attic/ and brought back to life in the Lazarus-CCR. For other historical information see http://www.freetype.org/freetype1/index.html

The gdbint package contains a set of units to interface to the GNU debugger (GDB) library, libgdb. It is used in the Free Pascal text-based IDE. The units are:
The gdbm unit is a translation of the gdbm.h header files, with some additional routines. The headers translated without any problems, the only thing that should be taken into account is that the GDBM SYNC constant (for open flags) has been renamed to GDMB DOSYNC because it conflicts with the gdbm sync function.
This information is based on the older, version 1 of GeckoPort. For the latest version see here .
GeckoPort is a Lazarus/Free Pascal version of Takanori Ito's Gecko SDK for Delphi, including the TGeckoBrowser component. Version 2 is based on automatically generated include-files from the idl files from the Gecko SDK. For this purpose the idltopas utility is used. This way it's earier to follow the fast Gecko-release cycle now gecko-developers do not maintain backwards compatibility anymore. You can find more information about the old version of GeckoPort here .
The GGI is an interface (header) to libggi, made by Sebastian Guenther, and contains the header translations of the GGI (General Graphic Interface) library. (See their homepage). It consists of units that are straight translations of the libraries header files. The following units are part of this package:
GLScene is an OpenGL based 3D library. It was initially written for Delphi, now it is running in C++ Builder, Kylix, Delphi and Lazarus.
FPC 2.4.0 includes an initial version of a Free Pascal interface for the GNU Multiple Precision Arithmetic Library in packages/gmp.

GradControls is a Package of "Gradient Controls". There are currently 2 Components in this Package: * TGradButton - Version: 1.5 - stable * TGradPageControl - Version 0.1 - very unstable - currently in development
The component in this demo generates dual-color gradients in different styles (circular, diagonal etc.). The idea for this component comes from a Delphi freeware component TGradient at http://www.delphiarea.com/downloads, written by Kambiz R. Khojasteh.
This is a list of libraries designed only to work with graphics. If you're looking for a library to be used for game development you should use a game framework or a game engine instead.
Lazarus component, to arrange components in a grid: rows, columns, width in columns, height in rows. It looks a bit more compatible to Delphi's [https://docwiki.embarcadero.com/Libraries/Sydney/en/Vcl.ExtCtrls.TGridPanel TGridPanel], though not completely (e.g. some properties are named differently, the control collection is [https://docwiki.embarcadero.com/Libraries/Sydney/en/Vcl.ExtCtrls.TControlItem TControlItem] instead of TGridPanelControl, and the later misses some [https://docwiki.embarcadero.com/Libraries/Sydney/en/Vcl.ExtCtrls.TControlItem_Properties properties] as well).
The package GTK1 is a header to the GTK 1.x libraries.
The package GTK2 is a header to the GTK 2.x libraries. The headers mostly try to be compatible to 2.6 with some 2.8 extensions.
H2Paswizard is the graphical user interface wrapper over H2Pas tool used to convert C headers to pascal.
HashLib4Pascal is a Delphi/FreePascal compatible library that provides an easy to use interface for computing hashes and checksums of strings (with a specified encoding), files, streams, byte arrays and untyped data to mention but a few. It also supports Incremental Hashing.
Hermes is a graphics library designed to do a very limited number of things and do them very well. Is designed to convert a source buffer with a specified pixel format to a destination buffer with possibly a different format at the maximum possible speed. The long feature list includes things like palette handling and clearing surfaces to a specific color, conversion of images from one format to another and more.
This component stores the recent files list into an .ini file and shows the result into a menu. It's possible to insert the list into any point of your menu. A method helps you to have access to all the properties and methods of the Menu Items, so for example you can specify the image of each item.
We have package "my_pkg" with components TComp1, TComp2 and want to add icons for components to IDE component pallete.
This is a guide on how to build components.
The iconvenc package is a header file for the POSIX iconv posix library on Unix. Note that currently we try to keep this header portable, so GNUisms are not allowed. A simple Pascal wrapper to do a string conversion is also added.
This IDE dialog allows to select a design time package where to add a new component.
With current Lazarus, it is possible to compile and install IDE packages using the lazbuild tool. See lazbuild .
Internet Tools is a library to process web pages and is intended to be easily usable.

A port of [http://jvcl.sourceforge.net JVCL's] TJvXPBar control that can display an icon, a header and zero or more clickable items in its client area. Use a TJvXPBar control on a form to display an XP style group box with items that can be clicked.
KControls is a set of components. Main components: KGrid/KDbGrid, KMemo, KHexEditor. Almost all controls are cross-IDE compatible (Delphi/C++Builder, Lazarus) and cross-platform compatible in Lazarus. KControls does not support RightToLeft languages.
The LazActiveX package contains the TActiveXContainer component and the IDE integration of the necessary tools to create ActiveX components from a type library or directly from the object (exe or dll). ActiveX is a Microsoft Windows technology and can only be used on that platform. Cross compilation to windows is possible but the typelib importer used to create the COM bindings works only on Windows (wine not tested).
This is an overview of the components included in Lazarus and a comparison to those included with Turbo Delphi (from 2006).
The "components" directory of the Lazarus source tree comes with a number of very useful components, and they are described below. Note that there are also other components which can be downloaded separately from the Lazarus Code and Component Repository .
