Lazarus 1.4.4 (x86/x64) | 107/108 Mb

The Lazarus IDE is a stable and feature rich visual programming environment for the FreePascal Compiler. It supports the creation of self-standing graphical and console applications and runs on Linux, FreeBSD, MacOSX and Windows.

Lazarus is the class libraries for Free Pascal that emulate Delphi. Free Pascal is a GPL'ed compiler that runs on Linux, Win32, OS/2, 68K and more. Free Pascal is designed to be able to understand and compile Delphi syntax, which is of course OOP.

Lazarus is the part of the missing puzzle that will allow you to develop Delphi like programs in all of the above platforms. Unlike Java which strives to be a write once run anywhere, Lazarus and Free Pascal strives for write once compile anywhere. Since the exact same compiler is available on all of the above platforms it means you don't need to do any recoding to produce identical products for different platforms.

Lazarus provides developers with a feature-rich development environment for Delphi, enabling them to create fully functional, cross-platform applications designed for both personal and commercial use.

With a history of more than 15 years, the Lazarus project includes a comprehensive IDE for Free Pascal that comes with debugging and compiling capabilities, along with additional components, frameworks and packages required in the development process.

An intuitive IDE

Thanks to the tab-based interface and the accessible toolbars, the IDE is very easy to work with. It comes with a detachable source code editor that allows syntax highlighting, line numbering, comment insertion, code completion and syntax checking, which are common features for any application of its kind.

You can use it to manage your project, import Delphi code and files to Lazarus, manage project requirements or use the included collection of templates to help you get started.

Integrated graphical form designer

Lazarus also comes with a graphical form designer, ready to assist developers in creating user interfaces with a more complex layout and multiple components. Its rich and diverse object library includes various components, such as drop-down lists, buttons, menus, text input fields, check boxes, shapes, scroll boxes, progress bars, navigation buttons, tool bars, tab-based menus, image lists, dialogs, data control tools, charts and the list does not end here. It can also integrate Pascal scripts, database management tools and specific LazControls.

The 'Object Inspector' helps you configure the properties of each item, set the response to user actions, manage anchors and set restrictions for specific widget sets. The application also comes with an integrated debugger that can help you quickly identify errors within your code, as well as a compiler that enables you to easily deploy the project.

An application suitable for any Delphi programmer

Lazarus is an open-source package that developers can use to build Delphi applications of all kinds. Thanks to the intuitive IDE and the wide range of components and functions, it can be considered a real asset to those who like working with Delphi.
