* fixed compilation of code that uses '@' pass by
reference. The following syntax is no longer supported:
var := IIF( .T., @var, var )
however you can still use the following:
funcall( IIF( bPassbyRef, @someVar, someVar ) )
+added support for the following statement:
WITH OBJECT <objexpression>
...
END
inside this statement you can use simplified form of sending
messages to the object specified by <objexpression>
:message( ) instead objexpression:message()
:property instead objexpression:property
The runtime error will be generated at the time of message
sending (or property access/assign) if <objexpression>
is not a value of type object.
You can use the reserved property:
:__withobject
to access/assign the controlling object.
*fixed support for command line response file (@file.clp)
to be compatible with Clipper (Clipper genertes a single
obj file)
*fixed memory leaks when there is a fatal error in autoopened
module (using DO ... statement)
*implicit startup functions are removed from the list of
functions before generation of output code
* source/pp/ppcomp.c
* source/pp/pplib.c
* source/pp/ppcore.c
* redefinition of #define no longer causes a memory leak
* fixed repeatable optional clauses
#xcommand SET <var1> [, <varN>] WITH <val> =>
<var1>:=<val>[; <varN>:=<val>]
* fixed compilation of optional clauses (when used in different
order then declared) -this fixes the following long
waiting bug:
#command MYCOMMAND [<mylist,...>] [MYCLAUSE <myval>] => ;
MyFunction( {<mylist>} [, <myval>] )
MYCOMMAND MYCLAUSE 321 "HELLO"
* fixed restricted macro match marker <x:&>
* tests/Makefile
- tests/pretest.prg
+ utils/hbpptest
+ utils/hbpptest/Makefile
+ utils/hbpptest/pretest.prg
* moved file 'pretest.prg' from tests to separate directory
to make easier validation of the preprocessor
* TODO
* added note to fix hb_objGetMethod() so it will not generate
error if there is no method
* doc/en/clipper.txt
* added documentation for WITH OBJECT usage
