FPC/Lazarus support about delphiast HOT 5 OPEN

I'm not familiar with FPC syntax. And to be honest, I don't need this. If FPC support is really needed, somebody has to lead this initiative. But I can help, of course.

FPC (freepascal / lazarus) is not that different. FPC is enginered to support Delphi as much as possible, but typically it's a couple of years behind EMB. Which is understandable.

The great thing about FPC is that it broadens the use of the code to linux and OS X. I use ubuntu a lot at home for instance, and being able to use my tools under linux is valuable.

One of the reasons Smart Pascal was not ported to OS X or Linux is that we used to much "delphi" centric components and code to make it portable. SMS would have been great under linux, being able to automate builds and generating nodeJS services. I presently have a build farm setup with 2 raspberry PI devices :)

Either way, it can be valuable to keep FPC in mind when writing code, as it broadens the use of the library to the FPC user-base as well. When possible ofcourse.

Is there a document that describe the difference between Delphi and FPC syntax?

from delphiast.

It's about 90% compatible.

Only difference (that springs to mind) is:

Event handlers must have @ when assigned:

FOnMyEvent:=@SomeProc;

And for generics you need to use specialization for some types.

E.g:

Type
TMySpecialList = Class(TObjectList[TSpecialItem])
//Add methods here
end;

Must be written like this:

TCustomSpecial = TObjectList[TSpecialItem];
TMySpecialList = Specialize(TCustomSpecial)
// add methods here
end;

See wiki: http://wiki.freepascal.org/Generics

Other than that (as far as I remember), its pretty much the same stuff.
Most Delphi projects compile just fine, as long as the above rules are followed, and taking third party components and dependencies into account ofcourse.

Note the [ and ] chars were used, as the site removed ordinary LESS and MORE chars :)

I made a pull request addressing this enhancement.
