Bugfixes

  • Bugfix: httpclient correct passes the path starting with /.
  • Bugfixes for the htmlparser module.
  • Bugfix: pegs.find did not respect start parameter.
  • Bugfix: dialogs.ChooseFilesToOpen did not work if only one file is selected.
  • Bugfix: niminst: nimrod is not default dir for every project.
  • Bugfix: Multiple yield statements in iterators did not cause local vars to be copied.
  • Bugfix: The compiler does not emit very inaccurate floating point literals anymore.
  • Bugfix: Subclasses are taken into account for try except matching.
  • Bugfix: Generics and macros are more stable. There are still known bugs left though.
  • Bugfix: Generated type information for tuples was sometimes wrong, causing random crashes.
  • Lots of other bugfixes: Too many to list them all.

Changes affecting backwards compatibility

  • Operators starting with ^ are now right-associative and have the highest priority.
  • Deprecated os.getApplicationFilename: Use os.getAppFilename instead.
  • Deprecated os.getApplicationDir: Use os.getAppDir instead.
  • Deprecated system.copy: Use substr or string slicing instead.
  • Changed and documented how generalized string literals work: The syntax module.re"abc" is now supported.
  • Changed the behaviour of strutils.%, ropes.% if both notations $# and $i are involved.
  • The pegs and re modules distinguish between replace and replacef operations.
  • The pointer dereference operation p^ is deprecated and might become ^p in later versions or be dropped entirely since it is rarely used. Use the new notation p[] in the rare cases where you need to dereference a pointer explicitly.
  • system.readFile does not return nil anymore but raises an EIO exception instead.
  • Unsound co-/contravariance for procvars has been removed.

Language Additions

  • Source code filters are now documented.
  • Added the linearScanEnd, unroll, shallow pragmas.
  • Added emit pragma for direct code generator control.
  • Case statement branches support constant sets for programming convenience.
  • Tuple unpacking is not enforced in for loops anymore.
  • The compiler now supports array, sequence and string slicing.
  • A field in an enum may be given an explicit string representation. This yields more maintainable code than using a constant array[TMyEnum, string] mapping.
  • Indices in array literals may be explicitly given, enhancing readability: [enumValueA: "a", enumValueB: "b"].
  • Added thread support via the threads core module and the --threads:on command line switch.
  • The built-in iterators system.fields and system.fieldPairs can be used to iterate over any field of a tuple. With this mechanism operations like == and hash are lifted to tuples.
  • The slice .. is now a first-class operator, allowing code like: x in 1000..100_000.

Compiler Additions

  • The compiler supports IDEs via the new group of idetools command line options.
  • The interactive mode (REPL) has been improved and documented for the first time.
  • The compiler now might use hashing for string case statements depending on the number of string literals in the case statement.

Library Additions

  • Added lists module which contains generic linked lists.
  • Added sets module which contains generic hash sets.
  • Added tables module which contains generic hash tables.
  • Added queues module which contains generic sequence based queues.
  • Added intsets module which contains a specialized int set data type.
  • Added scgi module.
  • Added smtp module.
  • Added encodings module.
  • Added re.findAll, pegs.findAll.
  • Added os.findExe.
  • Added parseutils.parseUntil and parseutils.parseWhile.
  • Added strutils.align, strutils.tokenize, strutils.wordWrap.
  • Pegs support a captured search loop operator {@}.
  • Pegs support new built-ins: \letter, \upper, \lower, \title, \white.
  • Pegs support the new built-in \skip operation.
  • Pegs support the $ and ^ anchors.
  • Additional operations were added to the complex module.
  • Added strutils.formatFloat, strutils.formatBiggestFloat.
  • Added unary < for nice looking excluding upper bounds in ranges.
  • Added math.floor.
  • Added system.reset and a version of system.open that returns a TFile and raises an exception in case of an error.
  • Added a wrapper for redis.
  • Added a wrapper for 0mq via the zmq module.
  • Added a wrapper for sphinx.
  • Added system.newStringOfCap.
  • Added system.raiseHook and system.outOfMemHook.
  • Added system.writeFile.
  • Added system.shallowCopy.
  • system.echo is guaranteed to be thread-safe.
  • Added prelude include file for scripting convenience.
  • Added typeinfo core module for access to runtime type information.
  • Added marshal module for JSON serialization.
