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

starting with a previous 2.3.1 or compiler built from the objc branch
+ added basic objcprotocol support (only for external protocols
currently)
o use in type declaration: "type xp = objcprotocol ... end;"
o when defining a root class that implements it:
"type yc = objcclass(xp) ... end" (note: no support yet
for something like "objcclass(id,xp)" or so)
o when defining a non-root class that implements a protocol:
"type zc = objcclass(nsobject,xp) ... end"
o includes support for "required" and "optional" sections
o no support yet for the objcprotocol(<protocol>) expression
that enables getting a class instance representing the
protocol (e.g., for use with "conformsToProtocol:")
o message names have to specified in protocol declarations,
but if an objcclass implements a protocol, the message names do
not have to be repeated (but if they are, they have to match;
the same goes when overriding inherited methods)
+ allow specifying the external name of Objective-C classes and
protocols, since classes and protocols can have the same name
(and you cannot use the same Pascal identifier in such caseq)
+ added NSObject protocol, and make the NSObject class use it
+ added missing NSObject class methods that have the same name
as instance methods (added "class" name prefix to avoid clashes)
* fixed several cases where the compiler did not treat Objective-C
classes/protocols the same as Object Pascal classes/interfaces
(a.o., forward declarations, alignment, regvars, several type
conversions, ...)
* allow "override" directive in objcclass declarations, and print
a hint if it's forgotten in an external declaration (because it
doesn't really matter there, and may make automated header
conversion harder than necessary) and an error if will be used in
a non-external declaration (because it is not possible to start
a new vmt entry-tree in Objective-C, you can only override parent
methods)
* reject objcclasses/protocols as parameters to typeof()
* don't try to test VMT validity of objcclasses/protocols
git-svn-id: branches/objc@13375 -
o support for declaring external Objective-C classes (see
rtl/inc/objcbase.pas), including derived classes
o support for converting methods of objcclasses into selectors
(see tests/test/tobjc1.pp)
o support for loading from/storing to fields of objcclasses
o support for calling Objective-C methods using regular
Object Pascal syntax (see tests/test/tobjc1.pp)
o some things that are known to be not yet working:
o automatic conversion from ID to objcclasses and back
o declaring and implementing new objcclasses/methods in Pascal code
o debug information (objcclasses are currently plain pointers
as far as the debugger knows)

the syntax is exactly the same as for "external", except for
the keyword. It is currently only active for Darwin targets.
It should also work at least for Linux targets, but only with
the GNU assembler (which is why it is not activated there)
+ test for this functionality
git-svn-id: trunk@12009 -
+ use {$bitpacking on/+} to change the meaning of "packed"
into "bitpacked" for arrays. This is the default for MacPas.
You can also define individual arrays as "bitpacked", but
this is not encouraged since this keyword is not known by
other compilers and therefore makes your code unportable.
+ pack(unpackedarray,index,packedarray) to pack
length(packedarray) elements starting at
unpackedarray[index] into packedarray.
+ unpack(packedarray,unpackedarray,index) to unpack
packedarray into unpackedarray, with the first
element being stored at unpackedarray[index]
* todo:
* "open packed arrays" and rtti for packed arrays are not
yet supported
* gdb does not properly support bitpacked arrays

(otherwise this breaks code which uses that name for a parameter
or variabled) -- this disables the ability to use properties
in objects until support is added elsewhere in the compiler,
but change is needed since it breaks the compilation of the
universal headers.
git-svn-id: trunk@2569 -
cdecl/cppdecl procedures on Mac OS/Mac OS X to fix compatibility with
GPC (slightly more efficient than Metrowerks behaviour below, but
less efficient in most cases than our previous scheme)
+ "mwpascal" procedure directive to support the const record parameter
behaviour of Metrowerks Pascal, which passes all const records by
reference
- invalid calling conventions for a certain cpu are rejected
- arm softfloat calling conventions
- -Sp for cpu dependend code generation
- several arm fixes
- remaining code for value open array paras on heap
name to lowercase(declaration_name). This prevents a normal user from
accessing the routine, but they can still be easily looked up within
the compiler. This is used for helper procedures and should facilitate
the writing of more processor independent code in the code generator
itself (mostly written by Peter)
+ new "createintern" constructor for tcal nodes to create a call to
helper exported using the "compilerproc" directive
+ support for high(dynamic_array) using the the above new things
+ definition of 'HASCOMPILERPROC' symbol (to be able to check in the
compiler and rtl whether the "compilerproc" directive is supported)
