Version 0.10.2 contains many language -changes, some of which may break your existing code. For your convenience, we -added a new tool called `nimfix <nimfix.html>`_ that will help you convert your -existing projects so that it works with the latest version of the compiler. - -Progress towards version 1.0 -~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Although Nim is still pre-1.0, we were able to keep the number of breaking -changes to a minimum so far. Starting with version 1.0, we will not introduce -any breaking changes between major release versions. -One of Nim's goals is to ensure that the compiler is as efficient as possible. -Take a look at the -`latest benchmarks <https://github.com/logicchains/LPATHBench/blob/master/writeup.md>`_, -which show that Nim is consistently near -the top and already nearly as fast as C and C++. Recent developments, such as -the new ``asyncdispatch`` module will allow you to write efficient web server -applications using non-blocking code. Nim now also has a built-in thread pool -for lightweight threading through the use of ``spawn``. - -The unpopular "T" and "P" prefixes on types have been deprecated. Nim also -became more expressive by weakening the distinction between statements and -expressions. We also added a new and searchable forum, a new website, and our -documentation generator ``docgen`` has seen major improvements. Many thanks to -Nick Greenfield for the much more beautiful documentation! - - - -What's left to be done -~~~~~~~~~~~~~~~~~~~~~~ - -The 1.0 release is actually very close. Apart from bug fixes, there are -two major features missing or incomplete: - -* ``static[T]`` needs to be defined precisely and the bugs in the - implementation need to be fixed. -* Overloading of the assignment operator is required for some generic - containers and needs to be implemented. - -This means that fancy matrix libraries will finally start to work, which used -to be a major point of pain in the language. - - -Nimble and other Nim tools -~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Outside of the language and the compiler itself many Nim tools have seen -considerable improvements. - -Babel the Nim package manager has been renamed to Nimble. Nimble's purpose -is the installation of packages containing libraries and/or applications -written in Nim. -Even though Nimble is still very young it already is very -functional. It can install packages by name, it does so by accessing a -packages repository which is hosted on a GitHub repo. Packages can also be -installed via a Git repo URL or Mercurial repo URL. The package repository -is searchable through Nimble. Anyone is free to add their own packages to -the package repository by forking the -`nim-lang/packages <https://github.com/nim-lang/packages>`_ repo and creating -a pull request. Nimble is fully cross-platform and should be fully functional -on all major operating systems. -It is of course completely written in Nim. - -Changelog -~~~~~~~~~ - -Changes affecting backwards compatibility ------------------------------------------ - -- **The language has been renamed from Nimrod to Nim.** The name of the - compiler changed from ``nimrod`` to ``nim`` too. -- ``system.fileHandle`` has been renamed to ``system.getFileHandle`` to - prevent name conflicts with the new type ``FileHandle``. -- Comments are now not part of the AST anymore, as such you cannot use them - in place of ``discard``. -- Large parts of the stdlib got rid of the T/P type prefixes. Instead most - types now simply start with an uppercased letter. The - so called "partial case sensitivity" rule is now active allowing for code - like ``var foo: Foo`` in more contexts. -- String case (or any non-ordinal case) statements - without 'else' are deprecated. -- Recursive tuple types are not allowed anymore. Use ``object`` instead. -- The PEGS module returns ``nil`` instead of ``""`` when an optional capture - fails to match. -- The re module returns ``nil`` instead of ``""`` when an optional capture - fails to match. -- The "symmetric set difference" operator (``-+-``) never worked and has been - removed. -- ``defer`` is a keyword now. -- ``func`` is a keyword now. -- The ``using`` language feature now needs to be activated via the new - ``{.experimental.}`` pragma that enables experimental language features. -- Destructors are now officially *experimental*. -- Standalone ``except`` and ``finally`` statements are deprecated now. - The standalone ``finally`` can be replaced with ``defer``, - standalone ``except`` requires an explicit ``try``. -- Operators ending in ``>`` are considered as "arrow like" and have their - own priority level and are right associative. This means that - the ``=>`` and ``->`` operators from the `future <future.html>`_ module - work better. -- Field names in tuples are now ignored for type comparisons. This allows - for greater interoperability between different modules. -- Statement lists are not converted to an implicit ``do`` block anymore. This - means the confusing ``nnkDo`` nodes when working with macros are gone for - good. - - -Language Additions ------------------- - -- The new concurrency model has been implemented including ``locks`` sections, - lock levels and object field ``guards``. -- The ``parallel`` statement has been implemented. -- ``deepCopy`` has been added to the language. -- The builtin ``procCall`` can be used to get ``super``-like functionality - for multi methods. -- There is a new pragma ``{.experimental.}`` that enables experimental - language features per module, or you can enable these features on a global - level with the ``--experimental`` command line option. - - -Compiler Additions ------------------- - -- The compiler now supports *mixed* Objective C / C++ / C code generation: - The modules that use ``importCpp`` or ``importObjc`` are compiled to C++ - or Objective C code, any other module is compiled to C code. This - improves interoperability. -- There is a new ``parallel`` statement for safe fork&join parallel computing. -- ``guard`` and ``lock`` pragmas have been implemented to support safer - concurrent programming. -- The following procs are now available at compile-time:: - - math.sqrt, math.ln, math.log10, math.log2, math.exp, math.round, - math.arccos, math.arcsin, math.arctan, math.arctan2, math.cos, - math.cosh, math.hypot, math.sinh, math.sin, math.tan, math.tanh, - math.pow, math.trunc, math.floor, math.ceil, math.fmod, - os.getEnv, os.existsEnv, os.dirExists, os.fileExists, - system.writeFile - -- Two backticks now produce a single backtick within an ``emit`` or ``asm`` - statement. -- There is a new tool, `nimfix <nimfix.html>`_ to help you in updating your - code from Nimrod to Nim. -- The compiler's output has been prettified. - -Library Additions ------------------ - -- Added module ``fenv`` to control the handling of floating-point rounding and - exceptions (overflow, division by zero, etc.). -- ``system.setupForeignThreadGc`` can be used for better interaction with - foreign libraries that create threads and run a Nim callback from these - foreign threads. -- List comprehensions have been implemented as a macro in the ``future`` - module. -- The new Async module (``asyncnet``) now supports SSL. -- The ``smtp`` module now has an async implementation. -- Added module ``asyncfile`` which implements asynchronous file reading - and writing. -- ``osproc.kill`` has been added. -- ``asyncnet`` and ``asynchttpserver`` now support ``SO_REUSEADDR``. - -Bugfixes --------- - -- ``nil`` and ``NULL`` are now preserved between Nim and databases in the - ``db_*`` modules. -- Fixed issue with OS module in non-unicode mode on Windows. -- Fixed issue with ``x.low`` - (`#1366 <https://github.com/Araq/Nim/issues/1366>`_). -- Fixed tuple unpacking issue inside closure iterators - (`#1067 <https://github.com/Araq/Nim/issues/1067>`_). -- Fixed ENDB compilation issues. -- Many ``asynchttpserver`` fixes. -- Macros can now keep global state across macro calls - (`#903 <https://github.com/Araq/Nim/issues/903>`_). -- ``osproc`` fixes on Windows. -- ``osproc.terminate`` fixed. -- Improvements to exception handling in async procedures. - (`#1487 <https://github.com/Araq/Nim/issues/1487>`_). -- ``try`` now works at compile-time. -- Fixes ``T = ref T`` to be an illegal recursive type. -- Self imports are now disallowed. -- Improved effect inference. -- Fixes for the ``math`` module on Windows. -- User defined pragmas will now work for generics that have - been instantiated in different modules. -- Fixed queue exhaustion bug. -- Many, many more. |
