## v0.18.0 - 01/03/2018

### Changes affecting backwards compatibility

#### Breaking changes in the standard library

- The ``[]`` proc for strings now raises an ``IndexError`` exception when
  the specified slice is out of bounds. See issue
  [#6223](https://github.com/nim-lang/Nim/issues/6223) for more details.
  You can use ``substr(str, start, finish)`` to get the old behaviour back,
  see [this commit](https://github.com/nim-lang/nimbot/commit/98cc031a27ea89947daa7f0bb536bcf86462941f) for an example.

- ``strutils.split`` and ``strutils.rsplit`` with an empty string and a
  separator now returns that empty string.
  See issue [#4377](https://github.com/nim-lang/Nim/issues/4377).

- Arrays of char cannot be converted to ``cstring`` anymore, pointers to
  arrays of char can! This means ``$`` for arrays can finally exist
  in ``system.nim`` and do the right thing. This means ``$myArrayOfChar`` changed
  its behaviour! Compile with ``-d:nimNoArrayToString`` to see where to fix your
  code.

- `reExtended` is no longer default for the `re` constructor in the `re`
  module.

- The behavior of ``$`` has been changed for all standard library collections. The
  collection-to-string implementations now perform proper quoting and escaping of
  strings and chars.

- `newAsyncSocket` taking an `AsyncFD` now runs `setBlocking(false)` on the
  fd.

- ``mod`` and bitwise ``and`` do not produce ``range`` subtypes anymore. This
  turned out to be more harmful than helpful and the language is simpler
  without this special typing rule.

- ``formatFloat``/``formatBiggestFloat`` now support formatting floats with zero
  precision digits. The previous ``precision = 0`` behavior (default formatting)
  is now available via ``precision = -1``.

- Moved from stdlib into Nimble packages:
  - [``basic2d``](https://github.com/nim-lang/basic2d)
    _deprecated: use ``glm``, ``arraymancer``, ``neo``, or another package instead_
  - [``basic3d``](https://github.com/nim-lang/basic3d)
    _deprecated: use ``glm``, ``arraymancer``, ``neo``, or another package instead_
  - [``gentabs``](https://github.com/lcrees/gentabs)
  - [``libuv``](https://github.com/lcrees/libuv)
  - [``numeric``](https://github.com/lcrees/polynumeric)
  - [``poly``](https://github.com/lcrees/polynumeric)
  - [``pdcurses``](https://github.com/lcrees/pdcurses)
  - [``romans``](https://github.com/lcrees/romans)
  - [``libsvm``](https://github.com/nim-lang/libsvm_legacy)
  - [``joyent_http_parser``](https://github.com/nim-lang/joyent_http_parser)

- Proc [toCountTable](https://nim-lang.org/docs/tables.html#toCountTable,openArray[A])
  now produces a `CountTable` with values correspoding to the number of occurrences
  of the key in the input. It used to produce a table with all values set to `1`.

  Counting occurrences in a sequence used to be:

  ```nim
  let mySeq = @[1, 2, 1, 3, 1, 4]
  var myCounter = initCountTable[int]()

  for item in mySeq:
    myCounter.inc item
  ```

  Now, you can simply do:

  ```nim
  let
    mySeq = @[1, 2, 1, 3, 1, 4]
    myCounter = mySeq.toCountTable()
  ```

- If you use ``--dynlibOverride:ssl`` with OpenSSL 1.0.x, you now have to
  define ``openssl10`` symbol (``-d:openssl10``). By default OpenSSL 1.1.x is
  assumed.

- ``newNativeSocket`` is now named ``createNativeSocket``.

- ``newAsyncNativeSocket`` is now named ``createAsyncNativeSocket``
  and it no longer raises an OS error but returns an ``osInvalidSocket`` when
  creation fails.

- The ``securehash`` module is now deprecated. Instead import ``std / sha1``.

- The ``readPasswordFromStdin`` proc has been moved from the ``rdstdin``
  to the ``terminal`` module, thus it does not depend on linenoise anymore.

#### Breaking changes in the compiler

- ``\n`` is now only the single line feed character like in most
  other programming languages. The new platform specific newline escape sequence is
  written as ``\p``. This change only affects the Windows platform.

- The overloading rules changed slightly so that constrained generics are
  preferred over unconstrained generics. (Bug #6526)

- We changed how array accesses "from backwards" like ``a[^1]`` or ``a[0..^1]`` are
  implemented. These are now implemented purely in ``system.nim`` without compiler
  support. There is a new "heterogeneous" slice type ``system.HSlice`` that takes 2
  generic parameters which can be ``BackwardsIndex`` indices. ``BackwardsIndex`` is
  produced by ``system.^``.
  This means if you overload ``[]`` or ``[]=`` you need to ensure they also work
  with ``system.BackwardsIndex`` (if applicable for the accessors).

- The parsing rules of ``if`` expressions were changed so that multiple
  statements are allowed in the branches. We found few code examples that
  now fail because of this change, but here is one:

```nim
t[ti] = if exp_negative: '-' else: '+'; inc(ti)
```

This now needs to be written as:

```nim
t[ti] = (if exp_negative: '-' else: '+'); inc(ti)
```

- The experimental overloading of the dot ``.`` operators now take
  an ``untyped``` parameter as the field name, it used to be
  a ``static[string]``. You can use ``when defined(nimNewDot)`` to make
  your code work with both old and new Nim versions.
  See [special-operators](https://nim-lang.org/docs/manual.html#special-operators)
  for more information.

- ``yield`` (or ``await`` which is mapped to ``yield``) never worked reliably
  in an array, seq or object constructor and is now prevented at compile-time.

### Library additions

- **Added ``sequtils.mapLiterals`` for easier construction of array and tuple literals.**

- Added ``system.runnableExamples`` to make examples in Nim's documentation easier
  to write and test. The examples are tested as the last step of
  ``nim doc``.

- Implemented ``getIoHandler`` proc in the ``asyncdispatch`` module that allows
  you to retrieve the underlying IO Completion Port or ``Selector[AsyncData]``
  object in the specified dispatcher.

- For string formatting / interpolation a new module
  called [strformat](https://nim-lang.org/docs/strformat.html) has been added
  to the stdlib.

- The `ReadyKey` type in the selectors module now contains an ``errorCode``
  field to help distinguish between ``Event.Error`` events.

- Implemented an `accept` proc that works on a `SocketHandle` in
  ``nativesockets``.

- Added ``algorithm.rotateLeft``.

- Added ``typetraits.$`` as an alias for ``typetraits.name``.

- Added ``system.getStackTraceEntries`` that allows you to access the stack
  trace in a structured manner without string parsing.

- Added ``parseutils.parseSaturatedNatural``.

- Added ``macros.unpackVarargs``.

- Added support for asynchronous programming for the JavaScript backend using
  the `asyncjs` module.

- Added true color support for some terminals. Example:
```nim
import colors, terminal

const Nim = "Efficient and expressive programming."

var
  fg = colYellow
  bg = colBlue
  int = 1.0

enableTrueColors()

for i in 1..15:
  styledEcho bgColor, bg, fgColor, fg, Nim, resetStyle
  int -= 0.01
  fg = intensity(fg, int)

setForegroundColor colRed
setBackgroundColor colGreen
styledEcho "Red on Green.", resetStyle
```

### Library changes

- ``echo`` now works with strings that contain ``\0`` (the binary zero is not
  shown) and ``nil`` strings are equal to empty strings.

- JSON: Deprecated `getBVal`, `getFNum`, and `getNum` in favour of
  `getBool`, `getFloat`, `getBiggestInt`. A new `getInt` procedure was also
  added.

- ``rationals.toRational`` now uses an algorithm based on continued fractions.
  This means its results are more precise and it can't run into an infinite loop
  anymore.

- ``os.getEnv`` now takes an optional ``default`` parameter that tells ``getEnv``
  what to return if the environment variable does not exist.

- The ``random`` procs in ``random.nim`` have all been deprecated. Instead use
  the new ``rand`` procs. The module now exports the state of the random
  number generator as type ``Rand`` so multiple threads can easily use their
  own random number generators that do not require locking. For more information
  about this rename see issue [#6934](https://github.com/nim-lang/Nim/issues/6934)

- ``writeStackTrace`` is now proclaimed to have no IO effect (even though it does)
  so that it is more useful for debugging purposes.

- ``db_mysql`` module: ``DbConn`` is now a ``distinct`` type that doesn't expose the
  details of the underlying ``PMySQL`` type.

- ``parseopt2`` is now deprecated, use ``parseopt`` instead.

### Language additions

- It is now possible to forward declare object types so that mutually
  recursive types can be created across module boundaries. See
  [package level objects](https://nim-lang.org/docs/manual.html#package-level-objects)
  for more information.

- Added support for casting between integers of same bitsize in VM (compile time and nimscript).
  This allows to, among other things, reinterpret signed integers as unsigned.

- Custom pragmas are now supported using pragma ``pragma``, please see language
  manual for details.

- Standard library modules can now also be imported via the ``std`` pseudo-directory.
  This is useful in order to distinguish between standard library and nimble package
  imports:

  ```nim
  import std / [strutils, os, osproc]
  import someNimblePackage / [strutils, os]
  ```

### Language changes

- The **unary** ``<`` is now deprecated, for ``.. <`` use ``..<`` for other usages
  use the ``pred`` proc.

- Bodies of ``for`` loops now get their own scope:

```nim
# now compiles:
for i in 0..4:
  let i = i + 1
  echo i
```

- To make Nim even more robust the system iterators ``..`` and ``countup``
  now only accept a single generic type ``T``. This means the following code
  doesn't die with an "out of range" error anymore:

```nim
var b = 5.Natural
var a = -5
for i in a..b:
  echo i
```

- ``atomic`` and ``generic`` are no longer keywords in Nim. ``generic`` used to be
  an alias for ``concept``, ``atomic`` was not used for anything.

- The memory manager now uses a variant of the TLSF algorithm that has much
  better memory fragmentation behaviour. According
  to [http://www.gii.upv.es/tlsf/](http://www.gii.upv.es/tlsf/) the maximum
  fragmentation measured is lower than 25%. As a nice bonus ``alloc`` and
  ``dealloc`` became O(1) operations.

- The compiler is now more consistent in its treatment of ambiguous symbols:
  Types that shadow procs and vice versa are marked as ambiguous (bug #6693).

- codegenDecl pragma now works for the JavaScript backend. It returns an empty
  string for function return type placeholders.

- Extra semantic checks for procs with noreturn pragma: return type is not allowed,
  statements after call to noreturn procs are no longer allowed.

- Noreturn proc calls and raising exceptions branches are now skipped during common type
  deduction in ``if`` and ``case`` expressions. The following code snippets now compile:
  ```nim
  import strutils
  let str = "Y"
  let a = case str:
    of "Y": true
    of "N": false
    else: raise newException(ValueError, "Invalid boolean")
  let b = case str:
    of nil, "": raise newException(ValueError, "Invalid boolean")
    elif str.startsWith("Y"): true
    elif str.startsWith("N"): false
    else: false
  let c = if str == "Y": true
    elif str == "N": false
    else:
      echo "invalid bool"
      quit("this is the end")
  ```

- Pragmas now support call syntax, for example: ``{.exportc"myname".}`` and
  ``{.exportc("myname").}``

- The ``deprecated`` pragma now supports a user-definable warning message for procs.

  ```nim
  proc bar {.deprecated: "use foo instead".} =
    return

  bar()
  ```

### Tool changes

- The ``nim doc`` command is now an alias for ``nim doc2``, the second version of
  the documentation generator. The old version 1 can still be accessed
  via the new ``nim doc0`` command.

- Nim's ``rst2html`` command now supports the testing of code snippets via an RST
  extension that we called ``:test:``::

  ```rst
  .. code-block:: nim
      :test:
    # shows how the 'if' statement works
    if true: echo "yes"
  ```
