[fpc-devel] Variables declaraction inside code
Something that I always thought very nice on other languages is the possible of adding variables inside the codes, I'm very happy using the FPC but came on my mind, FPC is always getting better and better (I first saw it like 2 years ago and I am impressed with its progress), would it on the future be possible? Declaring variables after the begin? /*Just random thoughts*/ Thank you, Bizz ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
[fpc-devel] Declare variables inside the code
*I have been playing on other languages sometimes and I see some
features that speed-up a lot the code creating. I'm posting here one, I
want to see what you think about it.
*
*Good:* fast algorithm testings, code creating
*Bad?:* not a standard of the pascal language
/*method* MyMethod;
*var* A, B: Integer;
*begin
*
{ Simple sample of a variable inside the method begin/end near to a
for-loop }
*var* I: Integer;
*for* I := a *to* b *do*...
{ Or even }
*for* *var* J: Integer := a *to* b *do*...
{ This is normal on languages like C++ and Java }
/*/end;/
*
*What do you think about*?

This could be made compatible with the FPC handling of Body, where
e.g. a program or a procedure body is a Body, parsed by
tcgprocinfo.parse_body().
The only required parser modification had to treat a For statement as
a Body, with an (optional) specialized Var section at its begin, and a
Statement after Do.
But this solution would look strange to C coders, which expect
variable declarations *after* the begin of an block, while Pascal
expects local variables declared *before* the begin of an block. OTOH
I don't think that it would be a big deal to allow for Pascal
declarations also at the begin of an block. The syntax would look like:
Block = "BEGIN" [Declarations] {Statement} "END" .

This already help, but what about declaring also after some code?
I like on Java/C++/PHP that I can create a for-loop that creates the
counter... sample on PHP:
for(var; condition; step) for($var=0; $var<1000; $var += 1)
This syntaxe is possible on C++, Java (its not equal, but its something
very close).
I would like to be able this:
[ some code after begin ]
DoSomething;
var I: Integer;
for I := 0 to 1000 do
DoAnotherThing(I);
[ inside the code ]

Yea, it looks like C, but it is not. The difference in C like languages
is that an declaration is just a kind of statement. Without this, I
think it makes no sense. But then you code C-like with pascal keywords.

I don't see any disadvantage writting a code with /C-like with pascal
keywords/, shortcuts are always welcome in order to code faster (also
this is the objective of the High-Level Languages, isn't?). I like
Pascal and I don't see why to resist against some improvements, the
language gets richer and easier. Some small details can also increase
the community.
Lets see the OOP, its very helpful and speedup a lot the work and has
been added to the Pascal. Same for generics.

Better move the loop into a local procedure, where you can declare really local variables. Or make the loop variable completely implicit and thus 100% local to the loop. |for i : integer := 0 to 1000 do ...; Vinzent. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel I like this idea, but I'm changing my mind,*maybe is better to keep the current way*, its not really needed to declare a variable inside the codes, its nice, I like it but its not really necessary. But something that has been pointed (by Joerg I belive) is the initialization of variables, what about it? This would be a nice thing and I don't see why not. I prefer to see: *var X: Integer = 0; Y: Integer = 100;* than *var X: Integer; Y: Integer; begin X := 0; Y := 100;* ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
