Seed7 Release 2011-02-20

Hello,


I have released a new version of Seed7: seed7_05_20110220.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:
- The handling of closure parameters in the compiler (comp.sd7) was
    improved.
- A free string memory management for small strings was introduced in
    "heaputl.h". This improves the performance of some programs with
    string processing by up to 20 percent.
- The "socket.s7i" library was improved to provide protocol
    independent network access.
- The function 'addrFamily' was added to the "socket.s7i" library.
- Several changes were done to support compiling with a C++ compiler.
- The compiler (comp.sd7) was improved to generate runtime library
    prototypes with const qualifier.
- The macros 'likely' and 'unlikely' were added to if-statements
    checking for exception conditions in the files "cmd_rtl.c" and
    "soc_rtl.c".
- The const qualifier was added to function prototypes in "hsh_rtl.c"
    and "hsh_rtl.h".
- The functions 'socInetAddr', 'socInetLocalAddr' and
    'socInetServAddr' in "soc_rtl.c" were improved to optionally use
    the function 'getaddrinfo'. With 'getaddrinfo' it is possible to
    access computers with IPv4 and IPv6 addresses. For Linux this
    feature is activated.
- Interpreter, compiler and runtime library were improved to support
    the action SOC_ADDR_FAMILY.
- The compiler (comp.sd7) was improved to generate better code when
    accessing the element of an array that was the result of another
    computation.
- The compiler (comp.sd7) was improved to generate code with fewer
    temporary variables for the actions ARR_IDX, ARR_LNG, STR_EQ and
    STR_NE.
- The initialisation of string constants in the compiler was
    improved.


Greetings Thomas Mertes
