[fpc-pascal] a proposal about with syntax
Suppose I have the following class: type TMyClass = class public property Caption: string read FCaption write FCaption; property Items[Index: Integer]: string read GetItem write SetItem; default; function Count: Integer; end; I would like to do this: with MyClassInstance as mci, SomethingElse do begin Caption := 'A new caption'; for i := 0 to Count - 1 do mci[i] := UpperCase(mci[i]); end; That is, to add an optional as clause to the with statement so that access array element in a structure is made easier. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

[fpc-pascal] fpcup for FreeBSD
(Cross posted: FPC+Laz lists) Hi all, I've updated the fpcup automatic FPC+Laz installer from svn for FreeBSD. Tested on PC BSD, (similar to FreeBSD 9 x64 but with built in x11). A quick test showed a clean box with just fpcup will install Laz trunk+FPC fixes_2.6 well. Of course fpcup can be adjusted to get FPC trunk etc. Source code as usual at https://bitbucket.org/reiniero/fpcup Download for x64 FreeBSD via https://bitbucket.org/reiniero/fpcup/downloads General changes in the dev version: - apart from svn download support, I've added mercurial and git support. (@Graeme: fpcup can download the new tiopf repo but will probably need to switch branches for it to be useful) - fpcup can now create the Lazarus setup.exe if you are on windows (or presumably wine) if you have the Inno Setup Compiler installed. Thanks to Martin Friebe for improving the Laz build batch scripts which made this possible! As usual, Ludo Brands I would appreciate comments, patches, as well as in this case an x86 build ;) Thanks, Reinier ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Re: [fpc-pascal] a proposal about with syntax
I don't know what's make it complex if there are 2 or more subject in the with? Context. A conflict case the two object were of the same class. Are you saying this case: with MyClassInstance1 as m, MyClassInstance2 do begin m.Property1 := 123; Property2 := 456; end; Here you don't know Property2 belongs to which object instance?? If so, this is not a problem at all, because even without as you still cannot distinguish, so the compiler should deny this kind of usage anyway, however, with as, you can do this: with MyClassInstance1 as m1, MyClassInstance2 as m2 do begin m1.Property1 := 123; m2.Property2 := 456; end; To summarize, as does NOT try to eliminate context ambiguity (also it won't make a clear context ambiguous), but provided some convenience when needed. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Re: [fpc-pascal] a proposal about with syntax
Hi, Also with using the longobj below, you have to declare it first (yet more manual temporary/helper variables). Also, once you do that, you don't need with as much to begin with since you could use a single char. variable name. BTW, I don't think Daniel was suggesting that we actually use a class helper for such cases - just demonstrating that it's possible. I have to admit I didn't even think of using a class helper, so that's fairly creative. It could also be a possible implementation pathway if someone decides to implement it - but I doubt it since if you have access to internal compiler structures, you already know what with is referring to. I am not sure anyone has decided that as is specifically a bad idea. (Correct me if I am wrong). Look at it the opposite way, though. For every request, there has to be somebody capable of implementing it in the compiler who has free time and considers it to be more important than all of the other things outstanding. I fully support having an as operator or something effectively similar, however I also know than submitting a patch is better than making a feature request. Also, I am happy just to have with at all. My other main language (ABAP) has lots of awesome stuff like Native DB integration, but somehow doesn't have WITH! (From the my limited Java experience, it seems Java doesn't have an easy alternative either).

There must be a way around that (Something like Self, but that refers to whatever you are using in With).

I'm a bit confused on this point. To me, WITH has been around for a long time, and is to me very Pascal. Probably because PAscal is one of the only languages that allows nested procedures, etc., and with seems similar to me. (Also, pretty much to me Borland = Pascal). Although I just wanted a keyword (like self), the AS proposal makes more sense if you use more than one item in the same WITH. (I usually don't because they would have the same fields anyway...) I think having functions/procedures with no arguments callable with procedurename() is un-pascal-like as well, but it hardly bothers me that FPK allows it. Just because I don't love it doesn't mean others don't. (There is a lot of C like syntax that has creeped into FPK, but I assume that'S either because it was easy to implement and a few people wanted it, or because it made porting C stuff to Pascal easier). One could say OOP isn't Pascal like because the original inventor didn't come up with TObject... Actually the only thing that makes me uncomfortable about the keyword as, is that it strangely reminds me of SQL. I suppose that isn't a bad thing though.
