#1591 — Seed7 Release 2015-08-23

Hello,

I have released a new version of Seed7: seed7_05_20150823.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 example program raytrace.sd7 has been added. This program is a
  raytracing demo.
- The library vector3d.s7i, which supports 3D vectors, has been
  added.
- The compiler s7c has been improved to create code to manage free
  lists for struct data. This avoids many calls of malloc() and
  free(). The maximum length of the free lists is determined
  automatically at run-time.
- In color.s7i the elements of the type color have been renamed to
  redLight, greenLight and blueLight. The files mahjong.sd7 and
  draw.s7i have been changed to use the new element names of the
  type color.
- The functions doubleToCharBuffer, fltDgts and fltSci in flt_rtl.c
  have been improved to work without calls of strlen().
- The function bigHexCStri in big_rtl.c has been improved to use
  fewer calls of memmove() and strlen().
- The function process_pragma() in analyze.c has been improved to
  use fewer calls of strlen().
- The function opendir in dir_dos.c and dir_win.c has been improved
  to work without calls of strcat().
- The functions striAsUnquotedCStri and bstriAsUnquotedCStri in
  striutl.c have been improved to use fewer calls of strlen().
- The function cp_to_command in striutl.c has been improved to use
  fewer calls of os_stri_strlen.
- The function getcaps in trm_cap.c has been improved to use fewer
  calls of strcat().
- The function fix_capability in trm_inf.c has been improved to use
  fewer calls of strcat().
- The function strLit in str_rtl.c has been improved to work
  without calls of strlen().
- The functions calculate_output_length and print_stri in error.c
  have been improved to use fewer calls of strlen().
- The function prot_os_stri has been removed from traceutl.c.
- The macros 'likely' and 'unlikely' have been added to functions in
  act_comp.c, analyze.c, arr_rtl.c, big_gmp.c, big_rtl.c, chr_rtl.c,
  cmd_rtl.c, cmd_unx.c, cmd_win.c, con_win.c, hshlib.c, hsh_rtl.c,
  soc_rtl.c, striutl.c and traceutl.c.
- Checks for err_info != OKAY_NO_ERROR have been replaced by checks
  for pointer variables beeing NULL in cmd_win.c, dir_rtl.c,
  fil_rtl.c, pcs_unx.c, pcs_win.c, striutl.c. Since references to
  err_info are used this variable cannot be placed into a register.
  The pointer variables used now can be placed into a register.
- Variables in big_rtl.c, dir_rtl.c and striutl.c have been changed
  to constants.

Regards,
Thomas Mertes
