rtl: add enumerators to the basic classes
tests: add enumerators test which compiles and work both by fpc and dcc
compiler:
+ start for-in loop implementation: implement for-in loop for types (enumerations and ranges), strings, arrays and sets. todo: perform type checking, optimize array and string loops - use temp for expression, implement for-in loop for classes
test:
+ add a simple test for the 'for-in' loop
compiler: fix string for-in loop. now it uses a temp variable to store string expression result
complier: fix for-in array loop. use a temp variable for the loop expression only if loop is not an open array loop
complier: continue enumerator implementation:
+ add operator enumerator which give an ability to add enumerator for an existent type (for example to override builtin string enumerator)
+ add class enumerator support via delphi compatible GetEnumerator method + enumerator class/object template (function MoveNext: Boolean; property Current)
+ tests
compiler: fix for-in loop for arrays. delphi does not copy arrays to a temp variable and it is possible to change array during loop. + test
compiler: add reference for the enumerator operator when it is used + another test for operator enumerator for a class
compiler: add reference for the enumerator operator when it is used + another test for operator enumerator for a class
compiler: enumerator directive support:
+ allow to mark methods and properties by 'enumerator MoveNext' and 'enumerator Current' modifiers. Parser checks return types and duplicates.
+ prefer *marked* by enumerator directive methods and properties than GetEnumerator and Current builtin symbols
+ increase ppu version
+ test
rtl: add IEnumerator and IEnumerable interfaces declarations
tests: for-in loop tests:
+ add small comment at the top of test program
compiler: allow 'enumerator MoveNext' for the interface function declaration + test
compiler: move all for-in loop helpers to the nflw unit
compiler: don't allow the compiler to choose the non-valid enumerator operator for the for-in loop

+ changes in compiler, utils, packages to resolve identifier conflicts with the new TObject methods (like changing of UnitName arguments to AUnitName, adding Classes. before the toString, etc). (issue #0014931)

* left old cpu-specific set helper code under ifdef FPC_OLD_BIGENDIAN_SETS
in case someone wants to write new assembler set helpers (although most
of them should be optimally generated by the compiler already if
http://wiki.freepascal.org/FPC_HowToDo#Bit.28field.29_getting.2Fsetting_primitives
are optimally implemented)
git-svn-id: trunk@13582 -
we support writing more digits than are defined (due to Delphi-
compatibility) and
a) correcting the precision of undefined digits makes no sense
b) as a result, this precision correction made some numbers that can be
represented exactly in single precision inexact
-- fixes mantis #14230
* no longer perform precision correction while determining the whole part
of numbers (usually did nothing anyway, and the rest is caught by the
final rounding)
git-svn-id: trunk@13574 -
* ucs-4 -> variant type cast (variant -> ucs-4 is not possible due to overloading contraints of fpc and how ucs-4 is implemented)
* some newlines fixed
git-svn-id: trunk@13451 -
from byte into tcrtcoord=1..255, since all crt unit coordinates are
1-based (not for Window() procedure, see comments in crth.inc;
mantis #13788)
git-svn-id: trunk@13191 -
* exeinfo: Properly handle long COFF section names. Bug #13499.
* lineinfo, lnfodwrf: Properly use executable image base and current module base address.

program that does nothing. It was also not logical, because the expected
free heap at the end is the total heap size minus any allocated blocks
and minus the memory that was allocated before heaptrc was activated
(as the old code calculated, and as it does again now -- mantis #13678)
git-svn-id: trunk@13124 -
o i386/i386.inc used a function (fpc_truely_ansistr_unique) is now
only included if FPC_HAS_FEATURE_ANSISTRINGS is enabled (all other
platforms use the Pascal-only implementations)
o inc/heap.inc relied on threading
o inc/threads.inc relied on exceptions, consoleio and stackcheck
o inc/system.inc: just a feature-related "variable not used"-hint

it can be reused in fpc_write_text_enum (currently it duplicates that
code). I seem to have lost my corresponding changes to text.inc though,
so removing the duplicate code will be for another time.
git-svn-id: trunk@13076 -
support for 4-character UTF-8 codepoints (mantis #11791)
* fixed UnicodeToUtf8() based on patch by A. J. Miller (mantis
#13075)
git-svn-id: trunk@12902 -
the use of Objective-C 1.0 constructs. Because it is a mode switch, it
can be used cumulatively with every syntax mode. Note that a {$mode xxx}
statement resets all mode switches as well, so you cannot use the
-Mobjectivec1 variant if you have such a statement in a unit. This
modeswitch is currently only enabled for Darwin/PowerPC and Darwin/i386,
as the backend support is not yet implemented for other platforms.
+ implemented selector() statement that can be used to create an Objective-C
selector for the message with the specified *constant* name (in the future,
it will also work for Objective-C method identifiers)
+ added SEL type to the system unit (the selector() statement returns it)
+ added all Objective-C segments to the assembler writers
+ (currently mostly dummy) objc1 unit that is automatically included if the
{$modeswitch objectivec1} statement is used
+ some tests for the selector() statement
git-svn-id: trunk@12870 -
* When OpenExeFile is called with an empty filename argument,
it apparently opens stdin and crashes immediately thereafter trying to seek in non-seekable stream.
The filename is empty whenever GetLineInfo is called with the address that does not belong to valid module.
git-svn-id: trunk@12802 -
* const s: string = icorbainterface; is possible now
* as operator is working now with corba interfaces
* supports helper function is working now with corba interfaces
