Fund Nim and help us develop it further!

2009-12-21 Version 0.8.6 released

The version jump from 0.8.2 to 0.8.6 acknowledges the fact that all development of the compiler is now done in Nimrod.

Bugfixes

  • The pragmas hint[X]:off and warning[X]:off now work.
  • Method call syntax for iterators works again (for x in lines.split()).
  • Fixed a typo in removeDir for POSIX that lead to an infinite recursion.
  • The compiler now checks that module filenames are valid identifiers.
  • Empty patterns for the dynlib pragma are now possible.
  • os.parseCmdLine returned wrong results for trailing whitespace.
  • Inconsequent tuple usage (using the same tuple with and without named fields) does not crash the code generator anymore.
  • A better error message is provided when the loading of a proc within a dynamic lib fails.

Additions

  • Added system.contains for open arrays.
  • The PEG module now supports the search loop operator @.
  • Grammar/parser: SAD|IND is allowed before any kind of closing bracket. This allows for more flexible source code formating.
  • The compiler now uses a bind table for symbol lookup within a bind context. (See manual.html#templates for details.)
  • discard """my long comment""" is now optimized away.
  • New --floatChecks: on|off switches and pragmas for better debugging of floating point operations. (See manual.html#pre-defined-floating-point-types for details.)
  • The manual has been improved. (Many thanks to Philippe Lhoste!)

Changes affecting backwards compatibility

  • The compiler does not skip the linking step anymore even if no file has changed.
  • os.splitFile(".xyz") now returns ("", ".xyz", "") instead of ("", "", ".xyz"). So filenames starting with a dot are handled differently.
  • strutils.split(s: string, seps: set[char]) never yields the empty string anymore. This behaviour is probably more appropriate for whitespace splitting.
  • The compiler now stops after the --version command line switch.
  • Removed support for enum inheritance in the parser; enum inheritance has never been documented anyway.
  • The msg field of system.E_base has now the type string, instead of cstring. This improves memory safety.
