Seed7 Release 2013-05-05

Hello,


I have released a new version of Seed7: seed7_05_20130505.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:
- Functions to compare arrays (compare, <, >, <=, >=) have been added
    to the library array.s7i.
- In seed7_05.s7i the functions hashCode and compare have been
    defined for enum types.
- In the library bigrat.s7i the operator parse has been improved. Now
    the parse operator accepts decimal numbers with repeating decimals.
- The function integer has been added to the library integer.s7i.
    This function converts a numeric string, with a specified radix, to
    an integer.
- The function bigInteger has been added to the library bigint.s7i.
    This function converts a numeric string, with a specified radix, to
    a bigInteger.
- The files encoding.s7i, gethttp.s7i, scanfile.s7i, scanstri.s7i,
    xml_ent.s7i and bas7.sd7 have been changed to use the new function
    integer instead of toInt (toInt was an undocumented internal
    function).
- Checks for the function integer have been added to chkint.sd7.
- Checks for the function bigInteger have been added to chkbig.sd7.
- The operator sci has been added to to the library complex.s7i. This
    operater converts a complex to a string in scientific notation.
- The compiler (s7c) has been improved to support the actions
    BIG_PARSE_BASED, TYP_CMP, ENU_CPY, ENU_CREATE and GEN_DESTR.
- The memory management in the interpreter has been improved. Now it
    is possible that a destructor is called and the object memory is
    not freed. This is used to free the memory of struct objects only,
    when the usage_count reaches zero.
- The UNUSED flag was defined in data.h and used to monitor if the
    object memory can be freed.
- The compiler has been improved to call the destructor for local
    interface objects (In process_local_declaration process_destr_call
    is called for INTERFACEOBJECT objects).
- The compiler has been improved to initialize set constants, that
    are part of a data structure (In walk_const_list SETOBJECT objects
    are added to set_const_table).
- The runtime library has been improved to use the action GEN_DESTR
    instead of PRC_NOOP as destructor for integer and other simple
    data types.


Regards,
Thomas Mertes
