Seed7 Release 2012-04-15

Hello,


I have released a new version of Seed7: seed7_05_20120415.tgz
In the Seed7 programming language new statements and operators
can be declared easily. Types are first class objects and therefore
templates/generics need no special syntax. Object orientation is
used when it brings advantages and not in places when other
solutions are more obvious.


Seed7 is covered by the GPL (and LGPL for the Seed7 runtime library).


Changelog:
- Documentation comments were added to "shell.s7i".
- A description of several C preprocessor macros used in "version.h"
    was added to the file "src/read_me.txt".
- In "chkset.sd7" tests for set difference and symmetric difference
    were added and tests for set intersection and set membership were
    improved.
- The compiler (comp.sd7) was improved to support the functions
    'pipe2' and 'pty' (actions: CMD_PIPE2 and CMD_PTY).
- The compiler was improved to provide better optimization for set
    difference, intersection, union and membership.
- The tracing support for sets in the compiler was improved.
- The program "chkccomp.c" was improved to use the C compiler to
    determine elements from the FILE structure.
- The new experimental function 'cmdPty' was added to "cmd_unx.c"
    and "cmd_win.c".
- The function 'filInputReady' in "fil_unx.c" and "fil_win.c" was
    improved to use the macro 'read_buffer_empty' (which is defined in
    "version.h" by the program "chkccomp.c").
- The makefiles were changed to write several macro definitions to
    "version.h", before the program "chkccomp.c" is compiled. This way
    "chkccomp.c" gets information about the C compiler from
    "version.h".
- The functions 'setDiff' and 'setSymdiff' in "set_rtl.c" were
    improved to work correctly for big sets.
- The function 'setNotElem' was removed from "set_rtl.c" and the
    compiler was changed to use !setElem() instead of setNotElem().
- The function 'prot_set' in "traceutl.c" was improved to work
    correctly, when 64-bit bitset elements are used.


Greetings Thomas Mertes
