But this makes the deep repository of available VCL widgets inaccessible without conversion. As mentioned previously, this is by design, although the LCL widget set should suffice for most applications.

No support for dynamically loadable packages.

Lack of Datasnap, which uses Embarcadero proprietary enterprise functionality, not a publicly documented system.

This can be complex, though less so than for Lazarus versions older than 0.9.30, based on FP 2.4.x.

Components for Delphi can be converted to work in Lazarus.

Alternatively, debug info can be stripped from EXEs (e.g. From 0.9.30 onwards, Lazarus supports external debug symbols program file size can be significantly reduced (via compiler options) by using an external symbols file.

Under Windows, the default size of an executable file is larger than the Delphi 6 or 7 equivalent, as Lazarus stores debug information within the executable, rather than as separate files.

While resembling Delphi in many ways, there are a few limitations regarding the performance and feature set, including: Simple, local, flat file databases through TBufDataset, TMemDataset and TSdfDataset.dBase and FoxPro, supported through the TDbf component.The following DBMSes are supported out of the box:

Programs can interact with DBMSes through code or by components dropped on a form.

Database development ĭevelopers can install packages that allow Lazarus to support several database management systems (DBMSes). Each widget set is supported by providing an interface which interacts directly with the set. This is done by separating the definition of common widget classes and their widgetset-specific implementation.

The standard application framework, Lazarus Component Library (LCL) was originally modeled after the Visual Component Library (VCL) in Delphi 6, but, unlike Delphi, is not restricted to Microsoft Windows operating systems.

The ability to create custom componentsĪrchitecture of the Lazarus Component Library.

Text resource manager for internationalisation (internationalization).

Data-aware widget set that allows the developer to see data in visual components in the designer to assist with development.

Data-connectivity components for MySQL, PostgreSQL, FireBird, Oracle, SQLite, Sybase, and others.

Non-visual components for common behaviors such as persistence of application settings.

GUI widgets or visual components such as edit boxes, buttons, dialogs, menus, etc.

A What You See Is What You Get ( WYSIWYG) visual windows layout designer.

Along with project management features, the Lazarus IDE also provides: Lazarus provides a highly visual development environment for the creation of rich user interfaces, application logic, and other supporting code artifacts, similar to Borland Delphi. An example is the Lazarus IDE itself, created from a single code base and available on all major platforms including the Raspberry Pi. For desktop applications a single source can target macOS, Linux, and Windows, with little or no modification.

Software developers use Lazarus to create native-code console and graphical user interface (GUI) applications for the desktop, and also for mobile devices, web applications, web services, visual components and function libraries for a number of different platforms, including Mac, Linux and Windows.Ī project created by using Lazarus on one platform can be compiled on any other one which Free Pascal compiler supports. Its goal is to provide an easy-to-use development environment for programmers developing with the Object Pascal language, which is as close as possible to Delphi. Lazarus is a free cross-platform visual integrated development environment (IDE) for rapid application development (RAD) using the Free Pascal compiler.
