![]() ![]() Windows itself is made up of hundreds of DLLs, as are many other large applications such as. Dynamically loadable libraries are typically used to develop add-ons for other programs, to develop libraries that can be called by programs written in other languages such as C and C++, or to partition large projects into chunks so that the project's developers don't step on each other's toes. dylib extension (dynamic shared library). dll extension (dynamic-link library, or DLL). As the name suggests, the library is not linked into your executable at compile-time, but instead is loaded at runtime. However, if you prefer to work in an integrated environment, you can use Lazarus to create a project for the console app and then edit and compile the code in the Lazarus IDE.Ī dynamically loadable library is usually a collection of compiled functions that can be called by other programs. You don't have to use Lazarus to develop console apps. You can create a console app with no more than a text editor and the Free Pascal compiler. The Free Pascal compiler and the utility programs included with it are all console apps, meaning they can be run from the console, a batch file, or from the Lazarus IDE. ![]() Console apps can also be powerful number crunching, modeling, or data processing programs that don't need a fancy GUI because they're started by other programs or from batch files (or shell scripts on unix/linux). Console apps include things like small utilities such as the Windows FC (file compare) program or the Unix cd and cp commands. In OS X and Linux the console is referred to as a terminal window. In Windows the console is usually referred to as a command prompt window. Instead they are usually launched from the console, read their input from the console, and write their output to the console. ![]() ![]() Like Delphi, Free Pascal and Lazarus are both general-purpose programming tools, meaning you can develop a wide variety of programs with them, including the following:Ĭonsole apps don't have a GUI. Complete source code is available not only for the Free Pascal compiler and Lazarus IDE, but also for all units that make up the Free Pascal RTL and Lazarus LCL. The Lazarus Component Library (LCL) includes equivalents for many of the familiar VCL controls such as forms, buttons, text boxes and so on that are used to create applications that have a graphical user interface (GUI).īoth Free Pascal and Lazarus are written in Pascal. Lazarus is an open-source development system that builds on the Free Pascal compiler by adding an integrated development environment (IDE) that includes a syntax-highlighting code editor and visual form designer, as well as a component library that's highly compatible with Delphi's Visual Component Library (VCL). These dozen or so units make up the core of what is usually referred to as the Free Pascal run-time library (RTL). Free Pascal also includes units such as Windows, ShellAPI, BaseUnix, Unix and DynLibs for accessing features specific to an operating system. This includes familiar units such as System, SysUtils, StrUtils, DateUtils, Classes, Variants, Math, IniFiles and Registry, which are included with Free Pascal on all supported platforms. Free Pascal's compatibility with Delphi includes not only support for the same Object Pascal programming language that Delphi uses, but also for many of the same libraries of powerful routines and classes that Delphi is justly known for. │ Deutsch (de) │ English (en) │ español (es) │ suomi (fi) │ français (fr) │ magyar (hu) │ Bahasa Indonesia (id) │ italiano (it) │ 日本語 (ja) │ 한국어 (ko) │ polski (pl) │ português (pt) │ русский (ru) │ slovenčina (sk) │ 中文(中国大陆) (zh_CN) │ 中文(台灣) (zh_TW) │įree Pascal (FPC) is an open-source Pascal compiler with two notable features: a high degree of Delphi compatibility and availability on a variety of platforms, including Windows, Mac OS X, and Linux. ![]()
