For example. Let's say you are creating a product on Windows using the standard Windows widgets. Now you want to create a Linux version.

First you decide what widget set you want to use. That's it. You've now just created a Linux version of the Windows product without any additional coding.

If the code is standard Delphi pascal and it uses the standard components found in Delphi then the answer is yes. These items are specific to Windows and would only work on and within Windows.

However, if you are only looking to create a Windows product using Free Pascal and the app then the answer would be yes. This hasn't been added to the LCL yet but it should be possible in the future.

In a nut shell this means that you can write your own proprietary software that just links to these libraries. You can sell your application without the need to supply or make available your code.

However, as with the compiler if you make modifications to the FCL or LCL you must make those changes available to the general public and the world.

The language was originally developed by Apple Computer as Clascal for the Lisa Workshop development system. As Lisa gave way to MacintoshApple collaborated with Niklaus Wirththe author of Pascal, to develop an officially standardized version of Clascal.

This was renamed Object Pascal. Through the mids, Object Pascal was the main programming language for early versions of the MacApp application framework.

Official support ended in Symantec ported Object Pascal to the PC, and developed a similar object framework on that platform. Borland added support for object-oriented programming to Turbo Pascal 5. Delphi remained mainstream for business applications on the PC into the early s, and was partly displaced in the s with the introduction of the. NET Framework. Pascal became a major language in the programming world in the s, with high-quality implementations on most minicomputer platforms and microcomputers.

Among the later was the UCSD Pascal system, which compiled to an intermediate p-System code format that could then run on multiple platforms. Pascal became one of the major languages in the company in this period. With the start of the Apple Lisa project, Pascal was selected as the main programming language of the platform, although this time as a compiler in contrast to the p-System interpreter.

Object Pascal is an extension of the Pascal language that was developed at Apple Computer by a team led by Larry Tesler in consultation with Niklaus Wirththe inventor of Pascal.

It is descended from an earlier object-oriented version of Pascal named Clascalwhich was available on the Lisa computer.

Object Pascal was needed to support MacAppan expandable Macintosh application framework that would now be termed a class library. Larry Tesler oversaw the project, which began very early in and became a product in The IDE includes the compiler and an editor with syntax highlighting and checking, a powerful debuggerand a class library.

Many developers preferred Think Pascal over Apple's implementation of Object Pascal because Think Pascal offered a much faster compile— link —debug cycle, and tight integration of its tools. The last official release of Think Pascal was 4. Symantec later released an unofficial version 4.

RAD Studio Features

MacApp 3. InBorland introduced similar extensions, also named Object Pascal, to the Turbo Pascal product for the Macintosh, and in for Turbo Pascal 5. When Borland refocused from DOS to Windows inthey created a successor to Turbo Pascal, named Delphiand introduced a new set of extensions to create what is now known as the Delphi language. The development of Delphi started in and Delphi 1. While code using the Turbo Pascal object model could still be compiled, Delphi featured a new syntax using the keyword class in preference to objectthe Create constructor and a virtual Destroy destructor and negating having to call the New and Dispose proceduresproperties, method pointers, and some other things.

These were inspired by the ISO working draft for object-oriented extensions, but many of the differences from Turbo Pascal's dialect such as the draft's requirement that all methods be virtual were ignored.

The Delphi language has continued to evolve over the years to support constructs such as dynamic arraysgenerics and anonymous methods. Object Pascal compilers are available for a wide range of operating systems and architectures. They support subsets of Object Pascal.

Still supported in Delphi and Free Pascal. Delphi doesn't. The Free Pascal 1. Free Pascal 2. The method implementation can also be made in a distinct location as in other Object Pascal dialects. Many features have been introduced continuously to Object Pascal with extensions to Delphi and extensions to FreePascal. In reaction to criticism, Free Pascal has adopted generics with the same syntax as Delphi, provided Delphi compatibility mode is selected, and both Delphi partial and Free Pascal more extensive support operator overloading.

Delphi has also introduced many other features since version 7, [6] including generics. Whereas FreePascal tries to be compatible to Delphi in Delphi compatibility mode, it also usually introduced many new features to the language that are not always available in Delphi.Oxygene lets you create applications and projects for all of today's major platforms — with one IDE and one great programming language.

And although it is in fact one of the older programming languages, it has greatly evolved into a modern, full featured language over the last decades. Pascal was initially developed in by Dr. It was used as a teaching language as well as a language for business applications. With the appearance of the Classic Mac OS, Pascal was the language of choice propagated by Apple for serious application development.

As an example, the first version of Photoshop was made with Pascal. Pascal was standardized as an ISO standard in the early 90s. But unlike other languages, there were different Pascal dialects and compilers since the very beginning. One of the most favourite versions, which made Pascal one of the most well-known and widespread programming languages of the 80s and the early 90s, was Borlands Turbo Pascal 2.

Over time some object-oriented additions were added to the language by Apple and later by Borland, which has evolved into what we now call Object Pascal. Today there are two major implementations: Delphithe official Turbo Pascal successor, and Free Pascal. It consists of the language, the compiler and a runtime-library - but does not include the RAD-tools which made Delphi famous.

But beside this historical excursion, what are the reasons that I use Free Pascal in my personal projects? Pascal is a compiled, statically-typed language, which requires, that you define the types of all variables, parameters and functions in your code. The type-safety has one big advantage: it forces you to think about how to structure your data.

The language offers many predefined types, but you can also define your own types.

It is even possible to create sub-ranges of types or to rename existing ones. Pascal is very strict, so the programmer has to differ between subroutines that return values, in Pascal called functionsand subroutines that does not return something, called procedures. Functions and procedures can also be passed to variables or other functions thanks to procedural types. It is possible to overload operators for specific types.OmniPascal is a project that enables Delphi and Free Pascal developers to write and maintain code using the modern editor Visual Studio Code.

Parameter hints See the parameters a method expects.I was tasked with building a small utility for copying out a few GB of files from a super-complicated folder structure, and convert it into a different structure, with the requirement that it should have an interactive GUI to do various selections interactivelyand run natively on Windows and Mac.

Couldn't have found an easier route than to build this in FPC with Lazarus. Even though I had hardly coded a line in the language before, it was built from scratch to "happy end-user" in 80 hours, including learning the language. On Mac, I needed to add a missing import statement or so. Simply an outstandingly productive tool for open source, cross-platform GUI development.

It's amazing to see how fast VS: Code is picking up extensions with full autocomplete, go-to definition, and other IDE-styled features.

Atom's equivalents are rarely as nice, unless you're using Nuclide because they wrote their own damned framework inside the editor to achieve those features! I'm still annoyed at small UI parts of VS: Code, but honestly the functionality and speed make it second to none in my opinion.

Correction: A few hundred GB of files actually I even created my first Real Linux desktop program two months ago to replace an XP status display screen in a factory. A real big step for me The progress on Lazarus is awesome, I am keeping eye on the project for past 5 or so years and it is getting so much better so fast. Currently it is best tool for making cross-platform desktop applications. Delphi is the MOST mismanaged language ever produce on earth!

The thing is so crazy that some people are considering seriously do a buy from the community ie: Pay money to buy the product Every half year there is a new version and then you get new bugs. I use Delphi XE2 and Lazarus 1. The main reason is that there are no more grey areas of my code, if something doesn't work, the documentation is missing or doesn't work the way I like, then right-click find the declaration and look at it or change it.

This includes the IDE. Portability is awesome. Being able to write your program in Lazarus Windows and then open it in Lazarus in Ubuntu and it just runs is amazing the first time you see it as a Delphi programmer.

The hardest part is migrating when you have third party components. Unless you can get the source code or a free pascal version you're stuck. I have an 85K line wine management system written in Delphi but it uses a lot of third party components so it is never going to just open and re-compile, however I have gone through changing a touchscreen module and it looks and feels the same except it also works in Linux!

Lastly I tend to agree, Delphi was badly mismanaged. For example I had to re-install XE2 on my new Windows 10 PC and I had to go through the most horrible install process getting it activated as it took 3 goes and required emails to support to prove I paid for it, the Official Delphi Forums are just about dead and there is still no free version which means nobody is ever going to learn it.

Note that I have not tried the most recent Delphi versions, but Lazarus 1. The mismanagement debate is almost a separate topic! There was massive pressure in the 's to convert to.

NET and C from corporate managers, auditors and customers, I never understood how this became such a force but In it was intense to the point of paranoia and a lot of my colleagues converted Delphi 8 sealed the deal in most cases. Needless to say most are now very happy with C.
