As mentioned in the -previous release notes, starting with version 1.0, we will not be introducing -any more breaking changes to Nim. - -The *language* itself is very close to 1.0, the primary area that requires -more work is the standard library. - -Take a look at the `download <download.html>`_ page for binaries (Windows-only) -and 0.11.0 snapshots of the source code. The Windows installer now also -includes `Aporia <https://github.com/nim-lang/aporia>`_, -`Nimble <https://github.com/nim-lang/nimble>`_ and other useful tools to get -you started with Nim. - -What's left to be done -~~~~~~~~~~~~~~~~~~~~~~ - -The 1.0 release is expected by the end of this year. Rumors say it will be in -summer 2015. What's left: - -* Bug fixes, bug fixes, bug fixes, in particular: - - The remaining bugs of the lambda lifting pass that is responsible to enable - closures and closure iterators need to be fixed. - - ``concept`` needs to be refined, a nice name for the feature is not enough. - - Destructors need to be refined. - - ``static[T]`` needs to be fixed. - - Finish the implementation of the 'parallel' statement. -* ``immediate`` templates and macros will be deprecated as these will soon be - completely unnecessary, instead the ``typed`` or ``untyped`` metatypes can - be used. -* More of the standard library should be moved to Nimble packages and what's - left should use the features we have for concurrency and parallelism. - - - -Changes affecting backwards compatibility ------------------------------------------ - -- Parameter names are finally properly ``gensym``'ed. This can break - templates though that used to rely on the fact that they are not. - (Bug #1915.) This means this doesn't compile anymore: - -.. code-block:: nim - - template doIt(body: stmt) {.immediate.} = - # this used to inject the 'str' parameter: - proc res(str: string) = - body - - doIt: - echo str # Error: undeclared identifier: 'str' -.. - - This used to inject the ``str`` parameter into the scope of the body. - Declare the ``doIt`` template as ``immediate, dirty`` to get the old - behaviour. -- Tuple field names are not ignored anymore, this caused too many problems - in practice so now the behaviour is as it was for version 0.9.6: If field - names exist for the tuple type, they are checked. -- ``logging.level`` and ``logging.handlers`` are no longer exported. - ``addHandler``, ``getHandlers``, ``setLogFilter`` and ``getLogFilter`` - should be used instead. -- ``nim idetools`` has been replaced by a separate - tool `nimsuggest <0.11.0/nimsuggest.html>`_. -- *arrow like* operators are not right associative anymore and are required - to end with either ``->``, ``~>`` or - ``=>``, not just ``>``. Examples of operators still considered arrow like: - ``->``, ``==>``, ``+=>``. On the other hand, the following operators are now - considered regular operators again: ``|>``, ``-+>``, etc. -- Typeless parameters are now only allowed in templates and macros. The old - way turned out to be too error-prone. -- The 'addr' and 'type' operators are now parsed as unary function - application. This means ``type(x).name`` is now parsed as ``(type(x)).name`` - and not as ``type((x).name)``. Note that this also affects the AST - structure; for immediate macro parameters ``nkCall('addr', 'x')`` is - produced instead of ``nkAddr('x')``. -- ``concept`` is now a keyword and is used instead of ``generic``. -- The ``inc``, ``dec``, ``+=``, ``-=`` builtins now produce OverflowError - exceptions. This means code like the following: - -.. code-block:: nim - var x = low(T) - while x <= high(T): - echo x - inc x - -Needs to be replaced by something like this: - -.. code-block:: nim - var x = low(T).int - while x <= high(T).int: - echo x.T - inc x - -- **Negative indexing for slicing does not work anymore!** Instead - of ``a[0.. -1]`` you can - use ``a[0.. ^1]``. This also works with accessing a single - element ``a[^1]``. Note that we cannot detect this reliably as it is - determined at **runtime** whether negative indexing is used! - ``a[0.. -1]`` now produces the empty string/sequence. -- The compiler now warns about code like ``foo +=1`` which uses inconsistent - spacing around binary operators. Later versions of the language will parse - these as unary operators instead so that ``echo $foo`` finally can do what - people expect it to do. -- ``system.untyped`` and ``system.typed`` have been introduced as aliases - for ``expr`` and ``stmt``. The new names capture the semantics much better - and most likely ``expr`` and ``stmt`` will be deprecated in favor of the - new names. -- The ``split`` method in module ``re`` has changed. It now handles the case - of matches having a length of 0, and empty strings being yielded from the - iterator. A notable change might be that a pattern being matched at the - beginning and end of a string, will result in an empty string being produced - at the start and the end of the iterator. -- The compiler and nimsuggest now count columns starting with 1, not 0 for - consistency with the rest of the world. - - -Language Additions ------------------- - -- For empty ``case object`` branches ``discard`` can finally be used instead - of ``nil``. -- Automatic dereferencing is now done for the first argument of a routine - call if overloading resolution produces no match otherwise. This feature - has to be enabled with - the `experimental <0.11.0/manual.html#pragmas-experimental-pragma>`_ pragma. -- Objects that do not use inheritance nor ``case`` can be put into ``const`` - sections. This means that finally this is possible and produces rather - nice code: - -.. code-block:: nim - import tables - - const - foo = {"ah": "finally", "this": "is", "possible.": "nice!"}.toTable() - - -- Ordinary parameters can follow after a varargs parameter. This means the - following is finally accepted by the compiler: - -.. code-block:: nim - template takesBlock(a, b: int, x: varargs[expr]; blck: stmt) = - blck - echo a, b - - takesBlock 1, 2, "some", 0.90, "random stuff": - echo "yay" - -- Overloading by 'var T' is now finally possible: - -.. code-block:: nim - proc varOrConst(x: var int) = echo "var" - proc varOrConst(x: int) = echo "const" - - var x: int - varOrConst(x) # "var" - varOrConst(45) # "const" - -- Array and seq indexing can now use the builtin ``^`` operator to access - things from backwards: ``a[^1]`` is like Python's ``a[-1]``. -- A first version of the specification and implementation of the overloading - of the assignment operator has arrived! -- ``system.len`` for strings and sequences now returns 0 for nil. - -- A single underscore can now be used to discard values when unpacking tuples: - -.. code-block:: nim - let (path, _, _) = os.splitFile("path/file.ext") - - -- ``marshal.$$`` and ``marshal.to`` can be executed at compile-time. -- Interoperability with C++ improved tremendously; C++'s templates and - operators can be wrapped directly. See - `this <0.11.0/nimc.html#additional-features-importcpp-pragma>`_ - for more information. -- ``macros.getType`` can be used to query an AST's type at compile-time. This - enables more powerful macros, for instance *currying* can now be done with - a macro. - - -Library additions ------------------ - -- ``reversed`` proc added to the ``unicode`` module. -- Added multipart param to httpclient's ``post`` and ``postContent`` together - with a ``newMultipartData`` proc. -- Added `%*` operator for JSON. -- The compiler is now available as Nimble package for c2nim. -- Added ``..^`` and ``..<`` templates to system so that the rather annoying - space between ``.. <`` and ``.. ^`` is not necessary anymore. -- Added ``system.xlen`` for strings and sequences to get back the old ``len`` - operation that doesn't check for ``nil`` for efficiency. -- Added sexp.nim to parse and generate sexp. - - -Bugfixes --------- - -- Fixed internal compiler error when using ``char()`` in an echo call - (`#1788 <https://github.com/Araq/Nim/issues/1788>`_). -- Fixed Windows cross-compilation on Linux. -- Overload resolution now works for types distinguished only by a -
