How do you call a FPC 64-bit Linux compiler from a 32-bit WINE editor?
That's where such solutions fall over.

Another good alternative, and extremely fast editor is jEdit.  Or even
MSEide is a good choice. I use the latter quite often these days, yet
I don't develop MSEgui based applications.

[fpc-pascal] When the variable freed in Optimize compile

[Zaher Dirkey]

Hi, I know when compile the project with optimize in Delphi the variable
freed/allocated after the last line used.
How can i make same in FPC, O3 not worked for me.
I used FPC 2.4.4

var
  c: Currency;
begin
   c := 10;
   writeln(c);

FPC only reuses stack slots allocated for temporary expressions. It  
does not reuse stack slots used by variables.

C (as a currency) is never 'freed'. It is declared throughout the whole 
procedure.

My prime topic in editors is dealing with line endings, because to
my surprise some editors still fail. The behavior I expect is:

1) Save in the same format as opened. Definitely no automatic conversion.
(Think of editing files on a samba share)
2) Ability of convert in "Save As" or similar.
3) Ability to fix files with mixed line endings.
(Hard to believe, but there are some win32 editors, which set the line endings 
of new lines to windows style but leave the other lines as they are in files 
with 
unix style.)

Just my 2 cents - MiSchi (admits to still use AlphaX on Mac OS X)

Yes. My recommendation for EditPlus is valid only for 32 bit Windows or
Linux/Wine. But there, nothing compares to it.

When I am using a plain editor for Pascal development, everything comes
down to real customization of syntax hilites and keyboard shortcuts,
powerful search & replace, integrated console window, jumping on the
source line by doubleclick etc. That's where EP shines, and, from my
point of view, no other editor compares.

An IDE is a different category. Lazarus or MSE.

To be honest, I would love it to see just one option, _the_ FreePascal IDE.

With my first 64-bit machine these days, I am going to switch to
Lazarus. Thought, you already did so, years ago? :)

Yes. Plus easy handling of UTF-8 vs. other encodings, with or without BOM.

No, but it seems very userfriendly and if you look in the description you see 
that the soucecode can be written in pascal also.

Why I not use MSEgui is because the cursor does not go behind a line ending.
This is a constraint when editing code.

I find that very hard to believe:
there are plenty of free good editors available (free). Some of them 
surely must be as good as.


There is valuable software out there, which is well worth the money and 
price the author asks for.
But an editor to me does not fall into this category. Price/value is not 
solely determined by features/quality of a single product (editor); it 
depends on the price of competing products. And with editors all the 
competition comes for free (only talking about those which are 
officially/legally free)


Anyway, that said, I had little need myself, to edit entire pascal 
projects outside an IDE. So i haven't spent to much time in comparison, 
and I am not planning on going to.
Neither am I looking to find a new editor for my personal usage. Just 
thought I add my 2 cents here.

2.5.1 since r17692 try this:

uses freebsd,baseunix,sysutils;

var pid : pid_t;
s: ansistring;
begin
  pid:=strtointdef(paramstr(1),-1);
  writeln('pid (-1 for current):',pid);
  // loads name of process + args with #0's inbetween.
  if kernproc_getargs(pid,s)<>-1 then // does not work with -1
writeln('arguments:',s)
  else
writeln('error fetching arguments:',fpgeterrno);

  // loads full path of running binary
  if kernproc_getpath(pid,s)<>-1 then   // -1 means own process
writeln('arguments:',s)
  else
writeln('error fetching path:',fpgeterrno);
end.

See the implementation of the above procedures in freebsd.pas for more info,
note that the kern_proc_* values were also updated in sysctl.

What if C is string or Interface of TInterfacedObject?


It is the same logic. It's freed only at the end.

For compiler-generated temporary variables, you should not make any assumptions.

I recently noticed that this is also true for ansistrings. I see this
can avoid lots of errors, but also makes it very ackward to
intentionally avoid copies when modifying strings in-place if they are
obtained from a function...
