Seed7 Release 2014-08-17

Show all headers | View raw

Hello,

I have released a new version of Seed7: seed7_05_20140817.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 chapter about files in the manual has been improved.
- Variants of the for-each-loop with an until condition have been
  added to array.s7i.
- The parse operator for characters has been improved to accept only
  strings with a length of 1.
- The function trimValue has been introduced. This function trims a
  string such that it can be converted to a specified type.
- The exception handlers for RANGE_ERROR have been removed from the
  functions read and readln in enable_input.s7i. The functions read
  and readln now raise range RANGE_ERROR when the conversion to the
  target type fails.
- Occurances of io_ok, io_error, io_empty and io_filled have been
  removed from the libraries. This undocumented feature was not used
  for years. The function succeeds and the functions read and readln
  with default value are better suited for error checking, when data
  is read.
- The exception handlers in interpreter and compiler have been
  improved to allow an otherwise part.
- The function succeeds has been introduced. This function executes
  a statement and returns TRUE when no exception occurs.
- The example programs nicoma.sd7 and savehd7.sd7 have been improved
  to use the new function succeeds.
- The parse operator for float has been changed to raise RANGE_ERROR
  when leading whitespace is found.
- The library make.s7i has been improved to accept the commands
  erase, xcopy, mv, move and rem.
- The library makedata.s7i has been improved to accept the macro
  functions subst and patsubst.
- The reading of rules in makedata.s7i has been improved to read
  commands without macro substitution. The macros in commands are
  substituted just before the commands are executed.
- The make functions in make.s7i have been changed to raise
  FILE_ERROR when a command fails.
- The function applyMacros in makedata.s7i has been improved to
  accept macro functions and the shorthands of patsubst.
- The function replaceSuffixes in makedata.s7i has been improved to
  accept pattern substitution with the % character.
- In the library make.s7i the logging has been removed from the
  functions doRm, doCp, doPwd, doEcho, doCd, doMake, doOneCommand,
  doCommands and processCommand.
- The program chkflt.sd7 has been adjusted to work with the strict
  parse operator for float.
- Interpreter and compiler have been improved to support the actions
  PRC_BLOCK_CATCH_ALL and PRC_BLOCK_OTHERWISE.
- The program sudo.c has been improved to work without upper limit
  for the parameter length.
- The functions checkIfOutsideRange and negate have been added to
  int_act.s7i.

Regards,
Thomas Mertes
