Seed7 Release 2015-03-08

Show key headers only | View raw

Hello,

I have released a new version of Seed7: seed7_05_20150308.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 compile time error messages have been improved. Now Unicode
  characters in the error line are displayed correctly. Before they
  have been displayed as question marks (?). When the error line is
  written to a console the encoding of the operating system is used.
  When stdout has been redirected to a file the error line is encoded
  with UTF-8. Thanks go to Arkady Kuleshov for triggering this
  improvement. The patch proposed by Arkady is based on stdout and
  UTF-8. The actual implementation uses a different approach via the
  console driver con_drv.h. The console driver uses UTF-16 under
  windows (unless stdout has been redirected) and UTF-8 under
  Linux/Unix/BSD.
- The function getBinary has been added to bin64.s7i. This function
  returns 64 bits from a bitset starting with a given bit number.
- The compiler has been changed to use the function getBinary to
  generate bitset literals.
- Interpreter and compiler have been improved to support the actions
  BIN_GET_BINARY_FROM_SET, PRC_FOR_DOWNTO_STEP and PRC_FOR_TO_STEP.
- The compiler function AppendWithDiagnostic has been renamed to
  appendWithDiagnostic.
- The function appendWithDiagnostic in comp/debug.s7i has been
  improved to add #line directives only when they are missing.
- The function defineTempConstant has been added to expr_util.s7i.
- The functions process_const_bin_radix and process_bin_radix in
  comp/bin_act.s7i have been improved to use uintRadix() and
  uintRadixPow2() for the actions BIN_radix and BIN_RADIX.
- The generation of for-loops in comp/prc_act.s7i has been improved.
- A definition of an integer for-loop with step has been added to
  forloop.s7i. Before integer for-loops with step were defined with
  the template FOR_STEP_DECLS.
- The functions prc_block, prc_block_catch_all, prc_block_otherwise,
  prc_repeat and prc_while in prclib.c have been improved to check
  for fail_flag with the macro unlikely().
- The functions check_for_int_to and check_for_int_downto in
  chkprc.sd7 have been improved.
- The program err.sd7 has been improved.
- The program chkccomp.c has been changed to write the version
  information to stdout when no file name has been provided as
  argument.
- A definition of the macro chrStrMacro has been added to chr_rtl.h.
- The function utf8_char in literal.c has been changed to call
  next_character() before reporting the errors CHAR_ILLEGAL,
  OVERLONG_UTF8_ENCODING, UTF16_SURROGATE_CHAR_FOUND and
  CHAR_NOT_UNICODE.
- The functions read_ustri8_line, ustri8_buffer_to_stri,
  calculate_output_length, print_stri and read_and_print_line have
  been added to error.c

Regards,
Thomas Mertes
