Seed7 Release 2015-09-14

Hello,


I have released a new version of Seed7: seed7_05_20150914.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 FAQ has been improved to explain the support for Unicode names
    and how Unicode names are activated with a pragma.
- The heap management for strings has been improved to determine the
    maximum length of the free lists automatically at run-time. This
    improves the runtime, when the compiler (s7c) compiles itself, by
    2.7% (measured with gcc and valgrind). In many other situations
    this optimization has also a positive effect.
- The interpreter has been improved to allow experimental support
    for case statements with a string decision expression.
- The compiler has been improved to use the functions abs()
    respectively labs() for the absolute value of an integer (when
    overflow checking is switched off).
- Tests for abs have been added to chkint.sd7.
- The example program raytrace.sd7 has been improved to use result
    variables with descriptive names.
- The configuration values LONG_SIZE and BOOLTYPE have been added to
    cc_conf.s7i.
- Interpreter and compiler have been changed to use the type _Bool
    or bool for boolean values, when one of them is available. This
    allows some optimizations by the C compiler, since the possible
    values are restricted to 0 and 1.
- The deprecated functions open_utf8, open_utf16, open_echo,
    open_line, open_tee, open_more, open_upper, open_lower,
    open_reverse, open_window and open_field have been removed.
    The replacement functions are openUtf8, openUtf16, openEcho,
    openLine, openTee, openMore, openUpper, openLower, openReverse,
    openWindow and openField.
- The deprecated function removeAnyFile has been removed. The
    replacement function is removeTree.
- The macros 'likely' and 'unlikely' have been added to functions in
    analyze.c, arrlib.c, biglib.c, bstlib.c, chrlib.c, cmdlib.c,
    dcllib.c, drw_win.c, drw_x11.c, fillib.c, fil_unx.c, fil_win.c,
    numutl.c, pollib.c, prclib.c, sql_lite.c, sql_my.c, sql_oci.c,
    sql_odbc.c, sql_post.c and ut8_rtl.c.
- The definition of the macro logFunction in common.h has been
    improved to write the file name.
- Calls of logFunction have been added to arrlib.c, prclib.c,
    big_gmp.c, cmd_unx.c cmd_win.c dir_dos.c, dir_win.c, drw_win.c,
    set_rtl.c, sql_lite.c, sql_my.c, sql_oci.c, sql_odbc.c, sql_post.c
    and sql_rtl.c.
- Checks for err_info != OKAY_NO_ERROR have been replaced by checks
    for pointer variables beeing NULL in sql_lite.c, sql_my.c,
    sql_oci.c, sql_odbc.c and sql_post.c. Since the address of
    err_info is used this variable cannot be placed into a register.
- Several variables have been changed to constants.
- Several calls of strlen() have been replaced with calls of the
    macro STRLEN() (STRLEN() computes the string size of a literal at
    compile-time).
- The files drw_win.c and tim_win.c have been improved to reduce the
    number of C compiler warnings.
- The function setupFiles in fil_win.c has been improved to set only
    redirected files to _O_BINARY mode. Real console files are left in
    _O_TEXT mode. This way the ENTER key is translated to '\n'.
- The function freelistStatistic has been added to heaputl.c.
- Several definitions have been changed to use a static storage
    class.


Regards,
Thomas Mertes
