Is Lazarus a good alternative for learning Delphi?_问答_开发者

I'm a teen who has been programming since 8 years old, so I know what I do. I want to take a look at Delphi Windows development.

The problem with this开发者_JAVA技巧, is that Embarcadero's Delphi is really expensive, and I can't afford it.

I wanted to know if Lazarus is a good alternative, now for learning and hobby, but in a few years for working.

If I learn Lazarus now, would I know Delphi also ? Do I need to learn Pascal first ? Any good Lazarus books ? If I learn Lazarus from a Delphi book it's ok ?.

Thanks.

Some things to be aware of:

The component library for lazarus, the LCL is similar in many ways, to the VCL library for Delphi, but there are differences, the biggest being the many components in the VCL that are not in lazarus. As a means of learning Delphi programming, this seems to me to be the biggest shortcoming.
The IDE for Lazarus is similar in many ways to the Delphi 7 IDE (and older versions) and looks nothing at all, and works nothing at all, like modern Delphi IDE versions. So your learning of Lazarus would be somewhat transferable to the now-ancient version Delphi 7, but wouldn't be of much use in knowing your way around the delphi IDE. Installation of packages works completely differently too. Delphi has true support for packages, whereas lazarus rebuilds and relinks itself in order to add more "designtime components" to itself.
The base languages are also almost identical, but I would expect to find some strange differences. There is some brief description of the differences on Wikipedia.

I agree with Kico; The delphi starter edition is not expensive.

there's a version of Delphi called Embarcadero Delphi XE Starter Edition, which have a very good price (free I guess).

I can't recommend Lazarus as a good option for learning Delphi because besides the languages are basically Pascal, they have some differences which could confuse you.

Here is the link for the old Turbo Delphi project (which became the Delphi XE Starter Edition) where you can download your copy.

There's already lots of views on this so take your pick. Mine for what it's worth, is that learning a language and more specifically HOW to program is the most important aspect. I know many skilled programmers who can and do use a multitude of languages - C, C++, Java, Ruby, Python, PHP, Delphi and so on. They all say to me that once you learn and are good at the fundamentals of a while loop, a for loop, and so on, applying that to a new language is easy enough.

I have not produced loads of software but I've achieved more in the last year using Lazarus and Free Pascal than I ever did with any other language - Python and Delphi included! I can easily create cross-platform GUI's that run on all OS'es with powerful procedures that I couldn't make with Python and\or Delphi. I am not saying they couldn't be made with those languages, but I was able to make them easily and quickly with Laz+FPC.

So, personally, even if I could afford to buy Delphi, I'd use Lazarus. I don't see that Delphi offers me, at my level, anything significant over and above Lazarus. So at your level and age, I'd say learn everything you can and when you outgrow Lazarus (if you ever do) move on to DELPHI. The interface transition will be easy enough once you know the language.

If you are still in school, you should check to see if there are educational discounts for Delphi

Primarily I think that you should let yourself be guided what your immediate surroundings use. The people on the forum you intend to frequent, friends, coworkers/students, whatever they use should be an important factor in what you do. Since they are the ones you will ask questions, exchange source etc.

They might be using older versions of Delphi, Lazarus or the newest of the newest Embarcadero version. E.g. for my work, I visit electrical engineering departments a lot, and they uniformly use a Delphi 6 or 7. And if not, usually older rather than newer.

If you are gearing up to do a bit of side jobs with Delphi you have a problem. You can buy starter to learn, but as soon as you start asking money for it, you have to acquire a full license(*), and the starter license is money lost. Specially since Embarcadero recently limited the period that old versions might upgrade, you might not even get a discount on the full version because of an older starter purchase in a few years.

Besides being free, Lazarus, for educational purposes has one big advantage: the number of versions in active use is usually limited to the last two releases. This reduces versionconflicts and at worst versionitis is only temporary. This means all your peers will more or less use the same version, while with Delphi they might be scattered over more than 5-6 versions.

And of course updating lazarus is also free :-) (which is important to consider in a multi year planning, the same people urging you to buy now will urge you to get the latest and greatest in a few years too)

Personally, I think that Lazarus is fine for the initial learning and that differences that really would be a stumbling block are much further down the track. And you get a VCL/LCL path to other platforms. You can always get a Delphi version later when plans are more concrete. (either to find employment, or if you start being a self employed programmer)

(*) luckily, if I understood it right, the starter edition now allows non commercial use in foundations.
