nim: Update to 1.6.0

Changelog:
Nim version 1.6 is now officially released!

A year in the making, 1.6 is the latest stable release and by far the largest
yet. We're proud of what we --- the core team and dedicated volunteers --- have
accomplished with this milestone:

  * 1667 PRs merged (1760 commits)
  * 893 issues closed
  * 15 new stdlib modules
  * new features in more than 40 stdlib modules, including major improvements
    to 10 commonly used modules
  * documentation and minor improvements to 170 modules, including 312 new
    runnable examples
  * 280 new nimble packages

Nim made its first entry in TIOBE index in 2017 at position 129, last year it
entered the top-100, and for 2 months the top-50 (link). We hope this release
will reinforce this trend, building on Nim's core strengths: a practical,
compiled systems programming language offering C++-like performance and
portability, Python-like syntax, Lisp-like flexibility, strong C, C++, JS,
Python interop, and best-in-class metaprogramming.

This release includes improvements in the following areas:

  * new language features (iterable[T], user-defined literals, private imports,
    strict effects, dot-like operators, block arguments with optional
    parameters)
  * new compiler features (nim --eval:cmd, custom nimscript extensions,
    customizable compiler messages)
  * major improvements to --gc:arc and --gc:orc
  * correctness and performance of integer and float parsing and rendering in
    all backends
  * significant improvements in error messages, showing useful context
  * documentation generation logic and documentation, in particular
    runnableExamples now works in more contexts
  * JS, VM and nimscript backend are more consistent with the C backend,
    allowing more modules to work with those backends, including the imports
    from std/prelude; the test suite now standardizes on testing stdlib modules
    on each major backend (C, JS, VM)
  * support for Apple silicon/M1, 32-bit RISC-V, armv8l, CROSSOS, improved
    support for NodeJS backend
  * major improvements to the following modules: system, math, random, json,
    jsonutils, os, typetraits, wrapnils, lists, hashes including performance
    improvements
  * deprecated a number of error prone or redundant features

Why use Nim?

  * One language to rule them all: from shell scripting to web frontend and
    backend, scientific computing, deep learning, blockchain client, gamedev,
    embedded, see also some companies using Nim.
  * Concise, readable and convenient: echo "hello world" is a 1-liner.
  * Small binaries: echo "hello world" generates a 73K binary (or 5K with
    further options), optimized for embedded devices (Go: 2MB, Rust: 377K, C++:
    56K) [1].
  * Fast compile times: a full compiler rebuild takes ~12s (Rust: 15min, gcc:
    30min+, clang: 1hr+, Go: 90s) [2].
  * Native performance: see Web Frameworks Benchmark, ray tracing, primes.
  * No need for makefiles, cmake, configure or other build scripts, thanks to
    compile-time function evaluation (CTFE) and dependency tracking [3].
  * Target any platform with a C compiler: Android and iOS, embedded systems,
    micro-controllers, WASM, Nintendo Switch, Game Boy Advance.
  * Zero-overhead interop lets you reuse code in C, C++ (including templates,
    C++ STL), JS, Objective-C, Python (via nimpy).
  * Built-in documentation generator that understands Nim code and runnable
    examples that stay in sync.

Last but not least, macros let you manipulate/generate code at compile time
instead of relying on code generators, enabling writing DSLs and language
extensions in user code. Typical examples include implementing Python-like
f-strings, optional chaining, command line generators, React-like Single Page
Apps, protobuf serialization and binding generators.

Installing Nim 1.6

We recommend everyone to upgrade to 1.6:

New users

Check out if your package manager already ships version 1.6 or install it as
described here.

Note: earlier this year researchers spotted malware written in Nim programming
language which supposedly led to antivirus vendors falsely tagging all software
written in Nim as a potential threat, including the Nim compiler, nimble (Nim'
s package manager) and so on (core Nim tooling is written entirely in Nim).
This has been an ongoing issue ever since - if you have any issues related to
this, please report the Nim compiler and associated tooling as false detection
to the respective antivirus vendors.

Existing users

If you have installed a previous version of Nim using choosenim, getting Nim
1.6 is as easy as:

choosenim update self
choosenim update stable

If you don't have choosenim, you can follow the same install link as above.

Building from source

git clone https://github.com/nim-lang/Nim
cd Nim
sh build_all.sh

The last command can be re-run after pulling new commits. Note that the
csources repo used was changed to csources_v1, the new setup is designed to be
forward and backward compatible.

Building from a CI setup

We now have bash APIs to (re-)build Nim from source which hide implementation
details, for example: . ci/funs.sh && nimBuildCsourcesIfNeeded. This can be
useful for CI when alternatives (using nightly builds or a Docker image) are
not suitable; in fact all the existing CI pipelines have been refactored to use
this, see #17815.

Contributors to Nim 1.6

Many thanks to our recurring and new contributors. Nim is a community driven
collaborative effort that welcomes all contributions, big or small.

Backward compatibility and preview flags

Starting with this release, we've introduced preview flags of the form
-d:nimPreviewX (e.g. -d:nimPreviewFloatRoundtrip), which allow users to opt-in
to new stdlib/compiler behavior that will likely become the default in the next
or a future release. These staging flags aim to minimize backward compatibility
issues.

We also introduced opt-out flags of the form -d:nimLegacyX, e.g.
-d:nimLegacyCopyFile, for cases where the default was changed to the new
behavior. For a transition period, these flags can be used to get the old
behavior.

Here's the list of these flags introduced in this release, refer to the text
below for explanations:

  * -d:nimLegacyCopyFile
  * -d:nimLegacyJsRound
  * -d:nimLegacyMacrosCollapseSymChoice
  * -d:nimLegacyParseQueryStrict
  * -d:nimLegacyRandomInitRand
  * -d:nimLegacyReprWithNewline
  * -d:nimLegacySigpipeHandler
  * -d:nimLegacyTypeMismatch
  * -d:nimPreviewDotLikeOps
  * -d:nimPreviewFloatRoundtrip
  * -d:nimPreviewHashRef
  * -d:nimPreviewJsonutilsHoleyEnum

Major new features

With so many new features, pinpointing the most salient ones is a subjective
exercise, but here are a select few:

iterable[T]

The iterable[T] type class was added to match called iterators, which solves a
number of long-standing issues related to iterators. Example:

iterator iota(n: int): int =
  for i in 0..<n: yield i

# previously, you'd need `untyped`, which caused other problems such as lack
# of type inference, overloading issues, and MCS.
template sumOld(a: untyped): untyped = # no type inference possible
  var result: typeof(block:(for ai in a: ai))
  for ai in a: result += ai
  result

assert sumOld(iota(3)) == 0 + 1 + 2

# now, you can write:
template sum[T](a: iterable[T]): T =
  # `template sum(a: iterable): auto =` would also be possible
  var result: T
  for ai in a: result += ai
  result

assert sum(iota(3)) == 0 + 1 + 2 # or `iota(3).sum`

In particular iterable arguments can now be used with the method call syntax.
For example:

import std/[sequtils, os]
echo walkFiles("*").toSeq # now works

See PR #17196 for additional details.

Strict effects

The effect system was refined and there is a new .effectsOf annotation that
does explicitly what was previously done implicitly. See the manual for more
details. To write code that is portable with older Nim versions, use this
idiom:

when defined(nimHasEffectsOf):
  {.experimental: "strictEffects".}
else:
  {.pragma: effectsOf.}

proc mysort(s: seq; cmp: proc(a, b: T): int) {.effectsOf: cmp.}

To enable the new effect system, compile with --experimental:strictEffects. See
also #18777 and RFC #408.

Private imports and private field access

A new import syntax import foo {.all.} now allows importing all symbols (public
or private) from foo. This can be useful for testing purposes or for more
flexibility in project organization.

Example:

from system {.all.} as system2 import nil
echo system2.ThisIsSystem # ThisIsSystem is private in `system`
import os {.all.} # weirdTarget is private in `os`
echo weirdTarget # or `os.weirdTarget`

Added a new module std/importutils, and an API privateAccess, which allows
access to private fields for an object type in the current scope.

Example:

import times
from std/importutils import privateAccess
block:
  let t = now()
  # echo t.monthdayZero # Error: undeclared field: 'monthdayZero' for type times.DateTime
  privateAccess(typeof(t)) # enables private access in this scope
  echo t.monthdayZero # ok

See PR #17706 for additional details.

nim --eval:cmd

Added nim --eval:cmd to evaluate a command directly, e.g.: nim --eval:"echo 1".
It defaults to e (nimscript) but can also work with other commands, e.g.:

find . | nim r --eval:'import strutils; for a in stdin.lines: echo a.toUpper'

# use as a calculator:
nim --eval:'echo 3.1 / (1.2+7)'
# explore a module's APIs, including private symbols:
nim --eval:'import os {.all.}; echo weirdTarget'
# use a custom backend:
nim r -b:js --eval:"import std/jsbigints; echo 2'big ** 64'big"

See PR #15687 for more details.

Round-trip float to string

system.addFloat and system.$ now can produce string representations of floating
point numbers that are minimal in size and possess round-trip and correct
rounding guarantees (via the Dragonbox algorithm). This currently has to be
enabled via -d:nimPreviewFloatRoundtrip. It is expected that this behavior
becomes the new default in upcoming versions, as with other nimPreviewX define
flags.

Example:

from math import round
let a = round(9.779999999999999, 2)
assert a == 9.78
echo a # with `-d:nimPreviewFloatRoundtrip`: 9.78, like in python3 (instead of  9.779999999999999)

New std/jsbigints module

Provides arbitrary precision integers for the JS target. See PR #16409.
Example:

import std/jsbigints
assert 2'big ** 65'big == 36893488147419103232'big
echo 0xdeadbeef'big shl 4'big # 59774856944n

New std/sysrand module

Cryptographically secure pseudorandom number generator, allows generating
random numbers from a secure source provided by the operating system. Example:

import std/sysrand
assert urandom(1234) != urandom(1234) # unlikely to fail in practice

See PR #16459.

New module: std/tempfiles

Allows creating temporary files and directories, see PR #17361 and followups.

import std/tempfiles
let tmpPath = genTempPath("prefix", "suffix.log", "/tmp/")
# tmpPath looks like: /tmp/prefixpmW1P2KLsuffix.log

let dir = createTempDir("tmpprefix_", "_end")
# created dir looks like: getTempDir() / "tmpprefix_YEl9VuVj_end"

let (cfile, path) = createTempFile("tmpprefix_", "_end.tmp")
# path looks like: getTempDir() / "tmpprefix_FDCIRZA0_end.tmp"
cfile.write "foo"
cfile.setFilePos 0
assert readAll(cfile) == "foo"
close cfile
assert readFile(path) == "foo"

User-defined literals

Custom numeric literals (e.g. -128'bignum) are now supported. Additionally, the
unary minus in -1 is now part of the integer literal, i.e. it is now parsed as
a single token. This implies that edge cases like -128'i8 finally work
correctly. Example:

func `'big`*(num: cstring): JsBigInt {.importjs: "BigInt(#)".}
assert 0xffffffffffffffff'big == (1'big shl 64'big) - 1'big

Dot-like operators

With -d:nimPreviewDotLikeOps, dot-like operators (operators starting with .,
but not with ..) now have the same precedence as ., so that a.?b.c is now
parsed as (a.?b).c instead of a.?(b.c). A warning is generated when a dot-like
operator is used without -d:nimPreviewDotLikeOps.

An important use case is to enable dynamic fields without affecting the
built-in . operator, e.g. for std/jsffi, std/json, pkg/nimpy. Example:

import std/json
template `.?`(a: JsonNode, b: untyped{ident}): JsonNode =
  a[astToStr(b)]
let j = %*{"a1": {"a2": 10}}
assert j.?a1.?a2.getInt == 10

Block arguments now support optional parameters

This solves a major pain point for routines accepting block parameters, see PR
#18631 for details:

template fn(a = 1, b = 2, body) = discard
fn(1, 2): # already works
  bar
fn(a = 1): # now works
  bar

Likewise with multiple block arguments via do:

template fn(a = 1, b = 2, body1, body2) = discard
fn(a = 1): # now works
  bar1
do:
  bar2

Other features

nim: Update to 1.4.6

Changelog:
Version 1.4.8 released

25 May 2021 The Nim Team

The Nim team is happy to announce version 1.4.8, our fourth patch release for
Nim 1.4.

Version 1.4.8 is a result of one month of hard work, and it contains 23 commits
, fixing the most important bugs and bringing additional improvements to our
ORC memory management.

We would recommend to all of our users to upgrade and use version 1.4.8.

Release highlights

  * Just like our devel branch, v1.4.8 is built using csources_v1, which means
    you can use it on Apple M1 chips.
  * Version 1.4.6 triggered some false positives with several antivirus
    softwares. Based on our testing, this shouldn't happen with v1.4.8.
  * Now you can use -d:release and -d:danger in your config files, no need to
    manually write these flags on the command line anymore.
  * Additional improvements to our ORC memory management. Use --gc:orc to
    compile your projects with it.


Version 1.4.6

Version 1.4.6 is our third patch release for Nim 1.4 and it brings several
fixes since version 1.4.4, released two month ago.

Bugfixes since 1.4.4

  * Fixed GC crash resulting from inlining of the memory allocation procs (link
    )
  * Fixed isolate doesn't work (#17264)
  * Fixed regression since 1.4.2: vm crash with lists.SinglyLinkedRing (#
    16384)
  * Fixed Generics sandwiched between two modules don't mixin their
    scope symbols properly (#11225)
  * Fixed json.% raises Defect for uint64 (#17383)
  * Fixed memory allocation during {.global.} init breaks GC (#17085)
  * Fixed incorrect raises effect for $(NimNode) (#17454)

Full changelog since v1.4.4 contains 19 commits.

nim: Update to 1.4.0

Changelog extracted from https://nim-lang.org/blog/2020/10/16/version-140-released.html

Standard library additions and changes

    Added some enhancements to std/jsonutils module.
        Added a possibility to deserialize JSON arrays directly to
        HashSet and OrderedSet types and respectively to serialize
        those types to JSON arrays via jsonutils.fromJson and
        jsonutils.toJson procedures.
        Added a possibility to deserialize JSON null objects to Nim
        option objects and respectively to serialize Nim option object
        to JSON object if isSome or to JSON null object if isNone via
        jsonutils.fromJson and jsonutils.toJson procedures.
        Added a Joptions parameter to jsonutils.fromJson currently
        containing two boolean options allowExtraKeys and
        allowMissingKeys.
            If allowExtraKeys is true NimгаСФ object to which the JSON
            is parsed is not required to have a field for every JSON
            key.
            If allowMissingKeys is true NimгаСФ object to which JSON is
            parsed is allowed to have fields without corresponding
            JSON keys.
    Added bindParams, bindParam to db_sqlite for binding parameters
    into a SqlPrepared statement.
    Added tryInsert,insert procs to db_* libs which accept primary key
    column name.
    Added xmltree.newVerbatimText support create styleгаСФ,scriptгаСФ
    text.
    uri module now implements RFC-2397.
    Added DOM Parser to the dom module for the JavaScript target.
    The default hash for Ordinal has changed to something more
    bit-scrambling. import hashes; proc hash(x: myInt): Hash =
    hashIdentity(x) recovers the old one in an instantiation context
    while -d:nimIntHash1 recovers it globally.
    deques.peekFirst and deques.peekLast now have var Deque[T] -> var T
    overloads.

    File handles created from high-level abstractions in the stdlib
    will no longer be inherited by child processes. In particular,
    these modules are affected: asyncdispatch, asyncnet, system,
    nativesockets, net and selectors.

    For asyncdispatch, asyncnet, net and nativesockets, an inheritable
    flag has been added to all procs that create sockets, allowing the
    user to control whether the resulting socket is inheritable. This
    flag is provided to ease the writing of multi-process servers,
    where sockets inheritance is desired.

    For a transition period, define nimInheritHandles to enable file
    handle inheritance by default. This flag does not affect the
    selectors module due to the differing semantics between operating
    systems.

    asyncdispatch.setInheritable, system.setInheritable and nativesockets.setInheritable are also introduced for setting file handle or socket inheritance. Not all platforms have these procs defined.

    The file descriptors created for internal bookkeeping by
    ioselector_kqueue and ioselector_epoll will no longer be leaked to
    child processes.
    strutils.formatFloat with precision = 0 has been restored to the
    version 1 behaviour that produces a trailing dot,
    e.g. formatFloat(3.14159, precision = 0) is now 3., not 3.

    Added commonPrefixLen to critbits.

    relativePath(rel, abs) and relativePath(abs, rel) used to silently
    give wrong results (see #13222); instead they now use
    getCurrentDir to resolve those cases, and this can now throw in
    edge cases where getCurrentDir throws. relativePath also now works
    for js with -d:nodejs.

    JavaScript and NimScript standard library changes:
    streams.StringStream is now supported in JavaScript, with the
    limitation that any buffer pointers used must be castable to ptr
    string, any incompatible pointer type will not work. The lexbase
    and streams modules used to fail to compile on NimScript due to a
    bug, but this has been fixed.

    The following modules now compile on both JS and NimScript:
    parsecsv, parsecfg, parsesql, xmlparser, htmlparser and
    ropes. Additionally supported for JS is cstrutils.startsWith and
    cstrutils.endsWith, for NimScript: json, parsejson, strtabs and
    unidecode.

    Added streams.readStr and streams.peekStr overloads to accept an
    existing string to modify, which avoids memory allocations,
    similar to streams.readLine (#13857).

    Added high-level asyncnet.sendTo and asyncnet.recvFrom UDP functionality.

    dollars.$ now works for unsigned ints with nim js.

    Improvements to the bitops module, including bitslices,
    non-mutating versions of the original masking functions,
    mask/masked, and varargs support for bitand, bitor, and bitxor.

    sugar.=> and sugar.-> changes: Previously (x, y: int) was
    transformed into (x: auto, y: int), it now becomes (x: int, y:
    int) for consistency with regular proc definitions (although you
    cannot use semicolons).

    Pragmas and using a name are now allowed on the lefthand side of =>.
    Here is an example of these changes:

    import sugar

    foo(x, y: int) {.noSideEffect.} => x + y

    # is transformed into

    proc foo(x: int, y: int): auto {.noSideEffect.} = x + y

    The fields of times.DateTime are now private, and are accessed
    with getters and deprecated setters.

    The times module now handles the default value for DateTime more
    consistently. Most procs raise an assertion error when given an
    uninitialized DateTime, the exceptions are == and $ (which returns
    "Uninitialized DateTime"). The proc times.isInitialized has been
    added which can be used to check if a DateTime has been
    initialized.

    Fix a bug where calling close on io streams in osproc.startProcess was a noop and led to hangs if a process had both reads from stdin and writes (e.g. to stdout).
    The callback that is passed to system.onThreadDestruction must now be .raises: [].

    The callback that is assigned to system.onUnhandledException must now be .gcsafe.

    osproc.execCmdEx now takes an optional input for stdin, workingDir and env parameters.

    Added a ssl_config module containing lists of secure ciphers as recommended by Mozilla OpSec

    net.newContext now defaults to the list of ciphers targeting гаЧЄntermediate compatibilityгаper MozillaгаСФ recommendation instead of ALL. This change should protect users from the use of weak and insecure ciphers while still provides adequate compatibility with the majority of the Internet.

    A new module std/jsonutils with hookable jsonTo,toJson,fromJson operations for json serialization/deserialization of custom types was added.
    A new proc heapqueue.find[T](heap: HeapQueue[T], x: T): int to get index of element x was added.
    Added rstgen.rstToLatex a convenience proc for renderRstToOut and initRstGenerator.
    Added os.normalizeExe.
    macros.newLit now preserves named vs unnamed tuples.
    Added random.gauss, that uses the ratio of uniforms method of sampling from a Gaussian distribution.
    Added typetraits.elementType to get the element type of an iterable.
    typetraits.$ changes: $(int,) is now "(int,)" instead of "(int)"; $tuple[] is now "tuple[]" instead of "tuple"; $((int, float), int) is now "((int, float), int)" instead of "(tuple of (int, float), int)"

    Added macros.extractDocCommentsAndRunnables helper.
    strformat.fmt and strformat.& support specifier =. fmt"{expr=}" now expands to fmt"expr={expr}".

    Deprecations: instead of os.existsDir use dirExists, instead of os.existsFile use fileExists.
    Added the jsre module, Regular Expressions for the JavaScript target..
    Made maxLines argument Positive in logging.newRollingFileLogger, because negative values will result in a new file being created for each logged line which doesnгаСХ make sense.
    Changed log in logging to use proper log level for JavaScript, e.g. debug uses console.debug, info uses console.info, warn uses console.warn, etc.
    Tables, HashSets, SharedTables and deques donгаСХ require anymore that the passed initial size must be a power of two - this is done internally. Proc rightSize for Tables and HashSets is deprecated, as it is not needed anymore. CountTable.inc takes val: int again not val: Positive; i.e. it can гаЧДount downгаagain.
    Removed deprecated symbols from macros module, some of which were deprecated already in 0.15.
    Removed sugar.distinctBase, deprecated since 0.19. Use typetraits.distinctBase.

    asyncdispatch.PDispatcher.handles is exported so that an external low-level libraries can access it.
    std/with, sugar.dup now support object field assignment expressions:

    import std/with

    type Foo = object
      x, y: int

    var foo = Foo()
    with foo:
      x = 10
      y = 20

    echo foo

    Proc math.round is no longer deprecated. The advice to use strformat instead cannot be applied to every use case. The limitations and the (lack of) reliability of round are well documented.

    Added getprotobyname to winlean. Added getProtoByname to nativesockets which returns a protocol code from the database that matches the protocol name.

    Added missing attributes and methods to dom.Navigator like deviceMemory, onLine, vibrate(), etc.
    Added strutils.indentation and strutils.dedent which enable indented string literals:

    import strutils
    echo dedent """
      This
        is
          cool!
      """

    Added initUri(isIpv6: bool) to uri module, now uri supports parsing ipv6 hostname.

    Added readLines(p: Process) to osproc.
    Added the below toX procs for collections. The usage is similar to procs such as sets.toHashSet and tables.toTable. Previously, it was necessary to create the respective empty collection and add items manually.
        critbits.toCritBitTree, which creates a CritBitTree from an openArray of items or an openArray of pairs.
        deques.toDeque, which creates a Deque from an openArray.
        heapqueue.toHeapQueue, which creates a HeapQueue from an openArray.
        intsets.toIntSet, which creates an IntSet from an openArray.

    Added progressInterval argument to asyncftpclient.newAsyncFtpClient to control the interval at which progress callbacks are called.
    Added os.copyFileToDir.

Language changes

    The =destroy hook no longer has to reset its target, as the compiler now automatically inserts wasMoved calls where needed.

    The = hook is now called =copy for clarity. The old name = is still available so there is no need to update your code. This change was backported to 1.2 too so you can use the more readable =copy without loss of compatibility.

    In the newruntime it is now allowed to assign to the discriminator field without restrictions as long as the case object doesnгаСХ have a custom destructor. The discriminator value doesnгаСХ have to be a constant either. If you have a custom destructor for a case object and you do want to freely assign discriminator fields, it is recommended to refactor the object into 2 objects like this:

    type
      MyObj = object
        case kind: bool
        of true: y: ptr UncheckedArray[float]
        of false: z: seq[int]

    proc `=destroy`(x: MyObj) =
      if x.kind and x.y != nil:
        deallocShared(x.y)

    Refactor into:

    type
      MySubObj = object
        val: ptr UncheckedArray[float]
      MyObj = object
        case kind: bool
        of true: y: MySubObj
        of false: z: seq[int]

    proc `=destroy`(x: MySubObj) =
      if x.val != nil:
        deallocShared(x.val)

    getImpl on enum type symbols now returns field syms instead of idents. This helps with writing typed macros. The old behavior for backwards compatibility can be restored with --useVersion:1.0.
    The typed AST for proc headers will now have the arguments be syms instead of idents. This helps with writing typed macros. The old behaviour for backwards compatibility can be restored with --useVersion:1.0.
    let statements can now be used without a value if declared with importc/importcpp/importjs/importobjc.
    The keyword from is now usable as an operator.
    Exceptions inheriting from system.Defect are no longer tracked with the .raises: [] exception tracking mechanism. This is more consistent with the built-in operations. The following always used to compile (and still does):

    proc mydiv(a, b): int {.raises: [].} =
      a div b # can raise an DivByZeroDefect

    Now also this compiles:

    proc mydiv(a, b): int {.raises: [].} =
      if b == 0: raise newException(DivByZeroDefect, "division by zero")
      else: result = a div b

    The reason for this is that DivByZeroDefect inherits from Defect and with --panics:on Defects become unrecoverable errors.
    Added the thiscall calling convention as specified by Microsoft, mostly for hooking purposes.
    Deprecated the {.unroll.} pragma, because it was always ignored by the compiler anyway.
    Removed the deprecated strutils.isNilOrWhitespace.
    Removed the deprecated sharedtables.initSharedTable.
    Removed the deprecated asyncdispatch.newAsyncNativeSocket.

    Removed the deprecated dom.releaseEvents and dom.captureEvents.

    Removed sharedlists.initSharedList, was deprecated and produces undefined behaviour.

    There is a new experimental feature called гаЧФtrictFuncsгаwhich makes the definition of .noSideEffect stricter. See here for more information.

    гаЧЗor-loop macrosга(see the manual) are no longer an experimental feature. In other words, you donгаСХ have to write pragma {.experimental: "forLoopMacros".} if you want to use them.

    Added the .noalias pragma. It is mapped to CгаСФ restrict keyword for the increased performance this keyword can enable.
    items no longer compiles with enums with holes as its behavior was error prone, see #14004.

    system.deepcopy has to be enabled explicitly for --gc:arc and --gc:orc via --deepcopy:on.
    Added the std/effecttraits module for introspection of the inferred effects. We hope this enables async macros that are precise about the possible exceptions that can be raised.
    The pragma blocks {.gcsafe.}: ... and {.noSideEffect.}: ... can now also be written as {.cast(gcsafe).}: ... and {.cast(noSideEffect).}: .... This is the new preferred way of writing these, emphasizing their unsafe nature.

Compiler changes
    Specific warnings can now be turned into errors via --warningAsError[X]:on|off.
    The define and undef pragmas have been de-deprecated.
    New command: nim r main.nim [args...] which compiles and runs main.nim, and implies --usenimcache so that the output is saved to $nimcache/main$exeExt, using the same logic as nim c -r to avoid recompilations when sources donгаСХ change. Example:

    nim r compiler/nim.nim --help # only compiled the first time
    echo 'import os; echo getCurrentCompilerExe()' | nim r - # this works too
    nim r compiler/nim.nim --fullhelp # no recompilation
    nim r --nimcache:/tmp main # binary saved to /tmp/main

    --hint:processing is now supported and means --hint:processing:on (likewise with other hints and warnings), which is consistent with all other bool flags. (since 1.3.3).
    nim doc -r main and nim rst2html -r main now call openDefaultBrowser.
    Added the new hint --hint:msgOrigin will show where a compiler msg (hint|warning|error) was generated; this helps in particular when itгаСФ non obvious where it came from either because multiple locations generate the same message, or because the message involves runtime formatting.
    Added the new flag --backend:js|c|cpp|objc (or -b:js etc), to change the backend; can be used with any command (e.g. nim r, doc, check etc); safe to re-assign.
    Added the new flag --doccmd:cmd to pass additional flags for runnableExamples, e.g.: --doccmd:-d:foo --threads use --doccmd:skip to skip runnableExamples and rst test snippets.
    Added the new flag --usenimcache to output binary files to nimcache.
    runnableExamples "-b:cpp -r:off": code is now supported, allowing to override how an example is compiled and run, for example to change the backend.
    nim doc now outputs under $projectPath/htmldocs when --outdir is unspecified (with or without --project); passing --project now automatically generates an index and enables search. See docgen for details.
    Removed the --oldNewlines switch.
    Removed the --laxStrings switch for mutating the internal zero terminator on strings.
    Removed the --oldast switch.
    Removed the --oldgensym switch.
    $getType(untyped) is now гаЧЦntypedгаinstead of гаЧЖxprга $getType(typed) is now гаЧХypedгаinstead of гаЧФtmtга
    Sink inference is now disabled per default and has to enabled explicitly via --sinkInference:on. Note: For the standard library sink inference remains enabled. This change is most relevant for the --gc:arc, --gc:orc memory management modes.

Tool changes
    nimsuggest now returns both the forward declaration and the implementation location upon a def query. Previously the behavior was to return the forward declaration only.

# v1.4.0 - yyyy-mm-dd

## Standard library additions and changes

  For `net` and `nativesockets`, an `inheritable` flag has been added to all
  `proc`s that create sockets, allowing the user to control whether the
  resulting socket is inheritable. This flag is provided to ease the writing of
  multi-process servers, where sockets inheritance is desired.

  For a transistion period, define `nimInheritHandles` to enable file handle
  inheritance by default. This flag does **not** affect the `selectors` module
  due to the differing semantics between operating systems.

  `system.setInheritable` and `nativesockets.setInheritable` is also introduced
  for setting file handle or socket inheritance. Not all platform have these
  `proc`s defined.

- The file descriptors created for internal bookkeeping by `ioselector_kqueue`
  and `ioselector_epoll` will no longer be leaked to child processes.

- `strutils.formatFloat` with `precision = 0` has been restored to the version
  1 behaviour that produces a trailing dot, e.g. `formatFloat(3.14159, precision = 0)`
  is now `3.`, not `3`.
- `critbits` adds `commonPrefixLen`.

- `relativePath(rel, abs)` and `relativePath(abs, rel)` used to silently give wrong results
  (see #13222); instead they now use `getCurrentDir` to resolve those cases,
  and this can now throw in edge cases where `getCurrentDir` throws.
  `relativePath` also now works for js with `-d:nodejs`.

- JavaScript and NimScript standard library changes: `streams.StringStream` is
  now supported in JavaScript, with the limitation that any buffer `pointer`s
  used must be castable to `ptr string`, any incompatible pointer type will not
  work. The `lexbase` and `streams` modules used to fail to compile on
  NimScript due to a bug, but this has been fixed.

  The following modules now compile on both JS and NimScript: `parsecsv`,
  `parsecfg`, `parsesql`, `xmlparser`, `htmlparser` and `ropes`. Additionally
  supported for JS is `cstrutils.startsWith` and `cstrutils.endsWith`, for
  NimScript: `json`, `parsejson`, `strtabs` and `unidecode`.

- Added `streams.readStr` and `streams.peekStr` overloads to
  accept an existing string to modify, which avoids memory
  allocations, similar to `streams.readLine` (#13857).

- Added high-level `asyncnet.sendTo` and `asyncnet.recvFrom`. UDP functionality.

- `paramCount` & `paramStr` are now defined in os.nim instead of nimscript.nim for nimscript/nimble.
- `dollars.$` now works for unsigned ints with `nim js`

- Improvements to the `bitops` module, including bitslices, non-mutating versions
  of the original masking functions, `mask`/`masked`, and varargs support for
  `bitand`, `bitor`, and `bitxor`.

- `sugar.=>` and `sugar.->` changes: Previously `(x, y: int)` was transformed
  into `(x: auto, y: int)`, it now becomes `(x: int, y: int)` in consistency
  with regular proc definitions (although you cannot use semicolons).

  Pragmas and using a name are now allowed on the lefthand side of `=>`. Here
  is an aggregate example of these changes:
  ```nim
  import sugar

  foo(x, y: int) {.noSideEffect.} => x + y

  # is transformed into

  proc foo(x: int, y: int): auto {.noSideEffect.} = x + y
  ```
- The fields of `times.DateTime` are now private, and are accessed with getters and deprecated setters.

- The `times` module now handles the default value for `DateTime` more consistently. Most procs raise an assertion error when given
  an uninitialized `DateTime`, the exceptions are `==` and `$` (which returns `"Uninitialized DateTime"`). The proc `times.isInitialized`
  has been added which can be used to check if a `DateTime` has been initialized.

- Fix a bug where calling `close` on io streams in osproc.startProcess was a noop and led to
  hangs if a process had both reads from stdin and writes (eg to stdout).

- The callback that is passed to `system.onThreadDestruction` must now be `.raises: []`.
- The callback that is assigned to `system.onUnhandledException` must now be `.gcsafe`.

- `osproc.execCmdEx` now takes an optional `input` for stdin, `workingDir` and `env`
  parameters.

- Added a `ssl_config` module containing lists of secure ciphers as recommended by
  [Mozilla OpSec](https://wiki.mozilla.org/Security/Server_Side_TLS)

- `net.newContext` now defaults to the list of ciphers targeting
  ["Intermediate compatibility"](https://wiki.mozilla.org/Security/Server_Side_TLS#Intermediate_compatibility_.28recommended.29)
  per Mozilla's recommendation instead of `ALL`. This change should protect
  users from the use of weak and insecure ciphers while still provides
  adequate compatibility with the majority of the Internet.

- A new module `std/jsonutils` with hookable `jsonTo,toJson,fromJson` operations for json
  serialization/deserialization of custom types was added.

- A new proc `heapqueue.find[T](heap: HeapQueue[T], x: T): int` to get index of element ``x``
  was added.
- Added `rstgen.rstToLatex` convenience proc for `renderRstToOut` and `initRstGenerator`
  with `outLatex` output.
- Added `os.normalizeExe`, e.g.: `koch` => `./koch`.
- `macros.newLit` now preserves named vs unnamed tuples; use `-d:nimHasWorkaround14720`
  to keep old behavior.
- Added `random.gauss`, that uses the ratio of uniforms method of sampling from a Gaussian distribution.
- Added `typetraits.elementType` to get element type of an iterable.
- `typetraits.$` changes: `$(int,)` is now `"(int,)"` instead of `"(int)"`;
  `$tuple[]` is now `"tuple[]"` instead of `"tuple"`;
  `$((int, float), int)` is now `"((int, float), int)"` instead of `"(tuple of (int, float), int)"`
- Added `macros.extractDocCommentsAndRunnables` helper

- `strformat.fmt` and `strformat.&` support `= specifier`. `fmt"{expr=}"` now
  expands to `fmt"expr={expr}"`.
- deprecations: `os.existsDir` => `dirExists`, `os.existsFile` => `fileExists`

- Added `jsre` module, [Regular Expressions for the JavaScript target.](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions)
- Made `maxLines` argument `Positive` in `logging.newRollingFileLogger`,
  because negative values will result in a new file being created for each logged
  line which doesn't make sense.
- Changed `log` in `logging` to use proper log level on JavaScript target,
  e.g. `debug` uses `console.debug`, `info` uses `console.info`, `warn` uses `console.warn`, etc.
- Tables, HashSets, SharedTables and deques don't require anymore that the passed
  initial size must be a power of two - this is done internally.
  Proc `rightSize` for Tables and HashSets is deprecated, as it is not needed anymore.
  `CountTable.inc` takes `val: int` again not `val: Positive`; I.e. it can "count down" again.
- Removed deprecated symbols from `macros` module, deprecated as far back as `0.15`.


## Language changes
- In newruntime it is now allowed to assign discriminator field without restrictions as long as case object doesn't have custom destructor. Discriminator value doesn't have to be a constant either. If you have custom destructor for case object and you do want to freely assign discriminator fields, it is recommended to refactor object into 2 objects like this:
  ```nim
  type
    MyObj = object
      case kind: bool
        of true: y: ptr UncheckedArray[float]
        of false: z: seq[int]

  proc `=destroy`(x: MyObj) =
    if x.kind and x.y != nil:
      deallocShared(x.y)
      x.y = nil
  ```
  Refactor into:
  ```nim
  type
    MySubObj = object
      val: ptr UncheckedArray[float]
    MyObj = object
      case kind: bool
      of true: y: MySubObj
      of false: z: seq[int]

  proc `=destroy`(x: MySubObj) =
    if x.val != nil:
      deallocShared(x.val)
      x.val = nil
  ```

nim: Update to 1.2.0

Changelog:
# v1.2.0 - 2020-04-02

## Standard library additions and changes

- Added overloaded `strformat.fmt` macro that use specified characters as
  delimiter instead of '{' and '}'.
- Added new procs in `tables.nim`: `OrderedTable.pop`, `CountTable.del`,
  `CountTable.pop`, `Table.pop`.
- Added `strtabs.clear` overload that reuses the existing mode.
- Added `browsers.osOpen` const alias for the operating system specific *"open"* command.
- Added `sugar.dup` for turning in-place algorithms like `sort` and `shuffle`
  into operations that work on a copy of the data and return the mutated copy,
  like the existing `sorted` does.
- Added `sugar.collect` that does comprehension for seq/set/table collections.
- Added `sugar.capture` for capturing some local loop variables when creating a
  closure. This is an enhanced version of `closureScope`.
- Added `typetraits.tupleLen` to get number of elements of a tuple/type tuple,
  and `typetraits.get` to get the ith element of a type tuple.
- Added `typetraits.genericParams` to return a tuple of generic params from a
  generic instantiation.
- `options` now treats `proc` like other pointer types, meaning `nil` proc variables
  are converted to `None`.
- Added `os.normalizePathEnd` for additional path sanitization.
- Added `times.fromUnixFloat,toUnixFloat`, sub-second resolution versions of
  `fromUnix`,`toUnixFloat`.
- Added `wrapnils` module for chains of field-access and indexing where the LHS
  can be nil. This simplifies code by reducing need for if-else branches around
  intermediate maybe nil values. E.g. `echo ?.n.typ.kind`.
- Added `minIndex`, `maxIndex` and `unzip` to the `sequtils` module.
- Added `os.isRelativeTo` to tell whether a path is relative to another.
- Added `resetOutputFormatters` to `unittest`.
- Added `expectIdent` to the `macros` module.
- Added `os.isValidFilename` that returns `true` if `filename` argument is valid
  for cross-platform use.
- Added `times.isLeapDay`
- `base64` adds URL-Safe Base64, implements RFC-4648 Section-7.
- Added a new module, `std / compilesettings` for querying the compiler about
  diverse configuration settings.
- Added `net.getPeerCertificates` and `asyncnet.getPeerCertificates` for
  retrieving the verified certificate chain of the peer we are connected to
  through an SSL-wrapped `Socket`/`AsyncSocket`.
- Added `browsers.openDefaultBrowser` without URL, implements IETF RFC-6694 Section-3.
- Added `jsconsole.trace`, `jsconsole.table`, `jsconsole.exception` for JavaScript target.
- Added `distinctBase` overload for values: `assert 12.MyInt.distinctBase == 12`
- Added new module `std/stackframes`, in particular `setFrameMsg`, which enables
  custom runtime annotation of stackframes, see #13351 for examples.
  Turn on/off via `--stackTraceMsgs:on/off`.
- Added `sequtils.countIt`, allowing for counting items using a predicate.
- Added a `with` macro for easy function chaining that's available everywhere,
  there is no need to concern your APIs with returning the first argument
  to enable "chaining", instead use the dedicated macro `with` that
  was designed for it. For example:

```nim
type
  Foo = object
    col, pos: string

proc setColor(f: var Foo; r, g, b: int) = f.col = $(r, g, b)
proc setPosition(f: var Foo; x, y: float) = f.pos = $(x, y)

var f: Foo
with(f, setColor(2, 3, 4), setPosition(0.0, 1.0))
echo f
```

- `macros.newLit` now works for ref object types.
- `macro pragmas` can now be used in type sections.
- 5 new pragmas were added to Nim in order to make the upcoming tooling more
  convenient to use. Nim compiler checks these pragmas for syntax but otherwise
  ignores them. The pragmas are `requires`, `ensures`, `assume`, `assert`, `invariant`.
- `system.writeFile` has been overloaded to also support `openarray[byte]`.
- `asyncdispatch.drain` now properly takes into account `selector.hasPendingOperations`
  and only returns once all pending async operations are guaranteed to have completed.
- `sequtils.zip` now returns a sequence of anonymous tuples i.e. those tuples
  now do not have fields named "a" and "b".
- `distinctBase` has been moved from `sugar` to `typetraits` and now it is
  implemented as compiler type trait instead of macro. `distinctBase` in sugar
  module is now deprecated.
- `CountTable.mget` has been removed from `tables.nim`. It didn't work, and it
  was an oversight to be included in v1.0.
- `tables.merge(CountTable, CountTable): CountTable` has been removed.
  It didn't work well together with the existing inplace version of the same proc
  (`tables.merge(var CountTable, CountTable)`).
  It was an oversight to be included in v1.0.
- `asyncdispatch.drain` now consistently uses the passed timeout value for all
  iterations of the event loop, and not just the first iteration.
  This is more consistent with the other asyncdispatch APIs, and allows
  `asyncdispatch.drain` to be more efficient.
- `base64.encode` and `base64.decode` were made faster by about 50%.
- `htmlgen` adds [MathML](https://wikipedia.org/wiki/MathML) support
  (ISO 40314).
- `macros.eqIdent` is now invariant to export markers and backtick quotes.
- `htmlgen.html` allows `lang` in the `<html>` tag and common valid attributes.
- `macros.basename` and `basename=` got support for `PragmaExpr`,
  so that an expression like `MyEnum {.pure.}` is handled correctly.
- `httpclient.maxredirects` changed from `int` to `Natural`, because negative values
  serve no purpose whatsoever.
- `httpclient.newHttpClient` and `httpclient.newAsyncHttpClient` added `headers`
  argument to set initial HTTP Headers, instead of a hardcoded empty `newHttpHeader()`.
- `parseutils.parseUntil` has now a different behaviour if the `until` parameter is
  empty. This was required for intuitive behaviour of the strscans module
  (see bug #13605).
- `strutils.formatFloat` with `precision = 0` has the same behavior in all
  backends, and it is compatible with Python's behavior,
  e.g. `formatFloat(3.14159, precision = 0)` is now `3`, not `3.`.
- `times.parse` now only uses input to compute its result, and not `now`:
  `parse("2020", "YYYY", utc())` is now `2020-01-01T00:00:00Z` instead of
  `2020-03-02T00:00:00Z` if run on 03-02; it also doesn't crash anymore when
  used on 29th, 30th, 31st of each month.
- `httpcore.==(string, HttpCode)` is now deprecated due to lack of practical
  usage. The `$` operator can be used to obtain the string form of `HttpCode`
  for comparison if desired.
- `std/oswalkdir` was buggy, it's now deprecated and reuses `std/os` procs.
- `net.newContext` now performs SSL Certificate checking on Linux and OSX.
  Define `nimDisableCertificateValidation` to disable it globally.
- `os.walkDir` and `os.walkDirRec` now have new flag, `checkDir` (default: false).
  If it is set to true, it will throw if input dir is invalid instead of a noop
  (which is the default behaviour, as it was before this change),
  `os.walkDirRec` only throws if top-level dir is invalid, but ignores errors for
  subdirs, otherwise it would be impossible to resume iteration.
- The `FD` variant of `selector.unregister` for `ioselector_epoll` and
  `ioselector_select` now properly handle the `Event.User` select event type.
- `joinPath` path normalization when `/` is the first argument works correctly:
  `assert "/" / "/a" == "/a"`. Fixed the edge case: `assert "" / "" == ""`.
- `xmltree` now adds indentation consistently to child nodes for any number
  of children nodes.
- `os.splitPath()` behavior synchronized with `os.splitFile()` to return "/"
  as the dir component of `/root_sub_dir` instead of the empty string.
- The deprecated `lc` macro has been removed from `sugar`. It is now replaced with the
  more powerful `collect` macro.
- `os.relativePath("foo", "foo")` is now `"."`, not `""`, as `""` means invalid
  path and shouldn't be conflated with `"."`; use `-d:nimOldRelativePathBehavior`
  to restore the old behavior.
- `os.joinPath(a, b)` now honors trailing slashes in `b` (or `a` if `b` = "").
- `base64.encode` no longer supports `lineLen` and `newLine`.
  Use `base64.encodeMime` instead.


## Language changes

- An `align` pragma can now be used for variables and object fields, similar
  to the `alignas` declaration modifier in C/C++.
- `=sink` type bound operator is now optional. Compiler can now use combination
  of `=destroy` and `copyMem` to move objects efficiently.
- Unsigned integer operators have been fixed to allow promotion of the first operand.
- Conversions to unsigned integers are unchecked at runtime, imitating earlier Nim
  versions. The documentation was improved to acknowledge this special case.
  See https://github.com/nim-lang/RFCs/issues/175 for more details.
- New syntax for lvalue references: `var b {.byaddr.} = expr` enabled by
  `import std/decls`.
- `var a {.foo.}: MyType = expr` now lowers to `foo(a, MyType, expr)` for
  non-builtin pragmas, enabling things like lvalue references (see `decls.byaddr`).


## Compiler changes

- Generated JS code uses spaces, instead of mixed spaces and tabs.
- The Nim compiler now supports the ``--asm`` command option for easier
  inspection of the produced assembler code.
- The Nim compiler now supports a new pragma called ``.localPassc`` to
  pass specific compiler options to the C(++) backend for the C(++) file
  that was produced from the current Nim module.
- The compiler now inferes "sink parameters". To disable this for a specific routine,
  annotate it with `.nosinks`. To disable it for a section of code, use
  `{.push sinkInference: off.}`...`{.pop.}`.
- The compiler now supports a new switch `--panics:on` that turns runtime
  errors like `IndexError` or `OverflowError` into fatal errors that **cannot**
  be caught via Nim's `try` statement. `--panics:on` can improve the
  runtime efficiency and code size of your program significantly.
- The compiler now warns about inheriting directly from `system.Exception` as
  this is **very bad** style. You should inherit from `ValueError`, `IOError`,
  `OSError` or from a different specific exception type that inherits from
  `CatchableError` and cannot be confused with a `Defect`.
- The error reporting for Nim's effect system has been improved.
- Implicit conversions for `const` behave correctly now, meaning that code like
  `const SOMECONST = 0.int; procThatTakesInt32(SOMECONST)` will be illegal now.
  Simply write `const SOMECONST = 0` instead.
- The `{.dynlib.}` pragma is now required for exporting symbols when making
  shared objects on POSIX and macOS, which make it consistent with the behavior
  on Windows.
- The compiler is now more strict about type conversions concerning proc
  types: Type conversions cannot be used to hide `.raise` effects or side
  effects, instead a `cast` must be used. With the flag `--useVersion:1.0` the
  old behaviour is emulated.
- The Nim compiler now implements a faster way to detect overflows based
  on GCC's `__builtin_sadd_overflow` family of functions. (Clang also
  supports these). Some versions of GCC lack this feature and unfortunately
  we cannot detect this case reliably. So if you get compilation errors like
  "undefined reference to `__builtin_saddll_overflow`" compile your programs
  with `-d:nimEmulateOverflowChecks`.


## Tool changes

- Nimpretty doesn't accept negative indentation argument anymore, because it was
  breaking files.

Update to 1.0.0

Changelog:
This is a major release containing nearly 60 commits. Most changes are bug fixes, but this release also includes a couple new features:

    Binaries can now be built and run using the new run command.
    The NimblePkgVersion is now defined so you can easily get the package version in your source code (example).

Some other highlights:

    Temporary files are now kept when the --debug flag is used.
    Fixed dependency resolution issues with "#head" packages (#432 and #672).
    The install command can now take Nim compiler flags via the new --passNim flag.
    Command line arguments are now passed properly to tasks (#633).
    The test command now respects the specified backend (#631).
    The dump command will no longer prompt and now has an implicit -y.
    Fixed bugs with the new nimscript executor (#665).
    Fixed multiple downloads and installs of the same package (#678).
    Nimble init no longer overwrites existing files (#581).
    Fixed incorrect submodule version being pulled when in a non-master branch (#675).

Update to 0.20.2

Changelog:
Changes affecting backwards compatibility

    All strutils.rfind procs now take start and last like strutils.find with the same data slice/index meaning. This is backwards compatible for calls not changing the rfind start parameter from its default. (#11487)

    In the unlikely case that you were using rfind X, start=N, or rfind X, N, then you need to change that to rfind X, last=N or rfind X, 0, N. (This should minimize gotchas porting code from other languages like Python or C++.)

    On Windows stderr/stdout/stdin are not opened as binary files anymore. Use the switch -d:nimBinaryStdFiles for a transition period.

Breaking changes in the standard library

    Mac OS X / BSD: TSa_Family is now the uint8 type, so type conversions like x.sin_family = uint16 toInt(nativesockets.AF_INET) need to be changed into x.sin_family = TSa_Family toInt(nativesockets.AF_INET).

Library additions

    toOpenArray is now available for the JS target.

Library changes

    Fix async IO operations stalling even after socket is closed. (#11232)

    More informative error message for streams.openFileStream. (#11438)

Compiler changes

    Better error message for IndexError for empty containers. (#11476)

    Fix regression in semfold for old right shift. (#11477)

    Fix for passing tuples as static params to macros. (#11423)

Update to 0.20.0

Changelog:
Changes affecting backwards compatibility

    shr is now sign preserving. Use -d:nimOldShiftRight to enable the old behavior globally.

    The isLower, isUpper family of procs in strutils/unicode operating on strings have been deprecated since it was unclear what these do. Note that the much more useful procs that operate on char or Rune are not affected.

    strutils.editDistance has been deprecated, use editdistance.editDistance or editdistance.editDistanceAscii instead.

    The OpenMP parallel iterator `||` now supports any #pragma omp directive and not just #pragma omp parallel for. See OpenMP documentation.

    The default annotation is parallel for, if you used OpenMP without annotation the change is transparent, if you used annotations you will have to prefix your previous annotations with parallel for.

    Furthermore, an overload with positive stepping is available.

    The unchecked pragma was removed, instead use system.UncheckedArray.

    The undocumented #? strongSpaces parsing mode has been removed.

    The not operator is now always a unary operator, this means that code like assert not isFalse(3) compiles.

    getImpl on a var or let symbol will now return the full IdentDefs tree from the symbol declaration instead of just the initializer portion.

    Methods are now ordinary гаЧФingleгаmethods, only the first parameter is used to select the variant at runtime. For backwards compatibility use the new --multimethods:on switch.

    Generic methods are now deprecated; they never worked well.

    Compile time checks for integer and float conversions are now stricter. For example, const x = uint32(-1) now gives a compile time error instead of being equivalent to const x = 0xFFFFFFFF'u32.

    Using typed as the result type in templates/macros now means гаЧЖxpression with a typeга The old meaning of typed is preserved as void or no result type at all.

    A bug allowed macro foo(): int = 123 to compile even though a macro has to return a NimNode. This has been fixed.

    With the exception of uint and uint64, conversion to unsigned types are now range checked during runtime.

    Macro arguments of type typedesc are now passed to the macro as NimNode like every other type except static. Use typed for a behavior that is identical in new and old Nim. See the RFC Pass typedesc as NimNode to macros for more details.

Breaking changes in the standard library

    osproc.execProcess now also takes a workingDir parameter.

    std/sha1.secureHash now accepts openArray[char], not string. (Former successful matches should keep working, though former failures will not.)

    options.UnpackError is no longer a ref type and inherits from system.Defect instead of system.ValueError.

    system.ValueError now inherits from system.CatchableError instead of system.Defect.

    The procs parseutils.parseBiggestInt, parseutils.parseInt, parseutils.parseBiggestUInt and parseutils.parseUInt now raise a ValueError when the parsed integer is outside of the valid range. Previously they sometimes raised an OverflowError and sometimes they returned 0.

    The procs parseutils.parseBin, parseutils.parseOct and parseutils.parseHex were not clearing their var parameter number and used to push its value to the left when storing the parsed string into it. Now they always set the value of the parameter to 0 before storing the result of the parsing, unless the string to parse is not valid (then the value of number is not changed).

    streams.StreamObject now restricts its fields to only raise system.Defect, system.IOError and system.OSError. This change only affects custom stream implementations.

    nreгаСФ RegexMatch.{captureBounds,captures}[] no longer return Option or nil/"", respectively. Use the newly added n in p.captures method to check if a group is captured, otherwise youгаСНl receive an exception.

    nreгаСФ RegexMatch.{captureBounds,captures}.toTable no longer accept a default parameter. Instead uncaptured entries are left empty. Use Table.getOrDefault() if you need defaults.

    nreгаСФ RegexMatch.captures.{items,toSeq} now returns an Option[string] instead of a string. With the removal of nil strings, this is the only way to indicate a missing match. Inside your loops, instead of capture == "" or capture == nil, use capture.isSome to check if a capture is present, and capture.get to get its value.

    nreгаСФ replace() no longer throws ValueError when the replacement string has missing captures. It instead throws KeyError for named captures, and IndexError for unnamed captures. This is consistent with RegexMatch.{captureBounds,captures}[].

    splitFile now correctly handles edge cases, see #10047.

    isNil is no longer false for undefined in the JavaScript backend: now itгаСФ true for both nil and undefined. Use isNull or isUndefined if you need exact equality: isNil is consistent with ===, isNull and isUndefined with ==.

    several deprecated modules were removed: ssl, matchers, httpserver, unsigned, actors, parseurl

    two poorly documented and not used modules (subexes, scgi) were moved to graveyard (they are available as Nimble packages)

    procs string.add(int) and string.add(float) which implicitly convert ints and floats to string have been deprecated. Use string.addInt(int) and string.addFloat(float) instead.

    case object branch transitions via system.reset are deprecated. Compile your code with -d:nimOldCaseObjects for a transition period.

    base64 module: The default parameter newLine for the encode procs was changed from "\13\10" to the empty string "".

Breaking changes in the compiler

    The compiler now implements the гаЧИeneric symbol prepassгаfor when statements in generics, see bug #8603. This means that code like this does not compile anymore:

proc enumToString*(enums: openArray[enum]): string =
  # typo: 'e' instead 'enums'
  when e.low.ord >= 0 and e.high.ord < 256:
    result = newString(enums.len)
  else:
    result = newString(enums.len * 2)

    discard x is now illegal when x is a function symbol.

    Implicit imports via --import: module in a config file are now restricted to the main package.

Library additions

    There is a new stdlib module std/editdistance as a replacement for the deprecated strutils.editDistance.

    There is a new stdlib module std/wordwrap as a replacement for the deprecated strutils.wordwrap.

    Added split, splitWhitespace, size, alignLeft, align, strip, repeat procs and iterators to unicode.nim.

    Added or for NimNode in macros.

    Added system.typeof for more control over how type expressions can be deduced.

    Added macros.isInstantiationOf for checking if the proc symbol is instantiation of generic proc symbol.

    Added the parameter isSorted for the sequtils.deduplicate proc.

    Added os.relativePath.

    Added parseopt.remainingArgs.

    Added os.getCurrentCompilerExe (implemented as getAppFilename at CT), can be used to retrieve the currently executing compiler.

    Added xmltree.toXmlAttributes.

    Added std/sums module for fast summation functions.

    Added Rusage, getrusage, wait4 to the posix interface.

    Added the posix_utils module.

    Added system.default.

    Added sequtils.items for closure iterators, allows closure iterators to be used by the mapIt, filterIt, allIt, anyIt, etc.

Library changes

    The string output of macros.lispRepr proc has been tweaked slightly. The dumpLisp macro in this module now outputs an indented proper Lisp, devoid of commas.

    Added macros.signatureHash that returns a stable identifier derived from the signature of a symbol.

    In strutils empty strings now no longer match as substrings.

    The Complex type is now a generic object and not a tuple anymore.

    The ospaths module is now deprecated, use os instead. Note that os is available in a NimScript environment but unsupported operations produce a compile-time error.

    The parseopt module now supports a new flag allowWhitespaceAfterColon (default value: true) that can be set to false for better Posix interoperability. (Bug #9619.)

    os.joinPath and os.normalizePath handle edge cases like "a/b/../../.." differently.

    securehash was moved to lib/deprecated.

    The switch -d:useWinAnsi is not supported anymore.

    In times module, procs format and parse accept a new optional DateTimeLocale argument for formatting/parsing dates in other languages.

Language additions

    Vm support for float32<->int32 and float64<->int64 casts was added.
    There is a new pragma block noSideEffect that works like the gcsafe pragma block.
    added os.getCurrentProcessId.
    User defined pragmas are now allowed in the pragma blocks.
    Pragma blocks are no longer eliminated from the typed AST tree to preserve pragmas for further analysis by macros.
    Custom pragmas are now supported for var and let symbols.
    Tuple unpacking is now supported for constants and for loop variables.
    Case object branches can be initialized with a runtime discriminator if possible discriminator values are constrained within a case statement.

Language changes

    The standard extension for SCF (source code filters) files was changed from .tmpl to .nimf, itгаСФ more recognizable and allows tools like Github to recognize it as Nim, see #9647. The previous extension will continue to work.

    Pragma syntax is now consistent. Previous syntax where type pragmas did not follow the type name is now deprecated. Also pragma before generic parameter list is deprecated to be consistent with how pragmas are used with a proc. See #8514 and #1872 for further details.

    Hash sets and tables are initialized by default. The explicit initHashSet, initTable, etc. are not needed anymore.

Tool changes

    jsondoc now includes a moduleDescription field with the module description. jsondoc0 shows comments as its own objects as shown in the documentation.
    nimpretty: гаЕГackup now defaults to off instead of on and the flag was undocumented; use git instead of relying on backup files.
    koch now defaults to build the latest stable Nimble version unless you explicitly ask for the latest master version via --latest.

Compiler changes

    The deprecated fmod proc is now unavailable on the VM.
    A new --outdir option was added.
    The compiled JavaScript file for the project produced by executing nim js will no longer be placed in the nimcache directory.
    The --hotCodeReloading has been implemented for the native targets. The compiler also provides a new more flexible API for handling the hot code reloading events in the code.
    The compiler now supports a --expandMacro:macroNameHere switch for easy introspection into what a macro expands into.
    The -d:release switch now does not disable runtime checks anymore. For a release build that also disables runtime checks use -d:release -d:danger or simply -d:danger.

Update to 0.19

Changelog:
WhatгаСФ new in 0.19.0

The nil state for strings/seqs is gone. Instead the default value for these is "" / @[]. Use --nilseqs:on for a transition period. This eliminates a large class of bugs that used to plague the average Nim code out there, including NimгаСФ standard library.

Accessing the binary zero terminator in NimгаСФ native strings is now invalid. Internally a Nim string still has the trailing zero for zero-copy interoperability with cstring. Compile your code with the new switch --laxStrings:on if you need a transition period.

These changes to strings and seqs give us more flexibility in how they are implemented and indeed alternative implementations are in development.

experimental is now a pragma and a command line switch that can enable specific language extensions, it is not an all-or-nothing switch anymore. We think this leads to a more robust development process where itгаСФ clearly documented which parts of Nim are bleeding edge and which parts can be relied upon.

Other notable language additions:

Dot calls combined with explicit generic instantiations can now be written as x.y[:z] which is transformed into y[z](x) by the parser.
func is now an alias for proc {.noSideEffect.}.

Anonymous tuples with a single element can now be written as (1,) with a trailing comma.

In order to make for loops and iterators more flexible to use Nim now supports so called гаЧЗor-loop macrosга See the manual for more details. This feature enables a Python-like generic enumerate implementation.

Case statements can now be rewritten via macros. See the manual for more information. This feature enables custom pattern matching.

The command syntax now supports keyword arguments after the first comma.

Thread-local variables can now be declared inside procs. This implies all the effects of the global pragma.

Nim now supports the except clause in the export statement.
Range float types, example range[0.0 .. Inf]. More details in language manual.

Breaking changes to be mindful of

The default location of nimcache for the native code targets was changed. Read the compiler user guide for more information.
Lots of deprecated symbols in the standard library that have been deprecated for quite some time now like system.expr or the old type aliases starting with a T or P prefix have been removed.
The exception hierarchy was slightly reworked, SystemError was renamed to CatchableError and is the new base class for any exception that is guaranteed to be catchable. This change should have minimal impact on most existing Nim code.

Async improvements

The гаЧДlosure iteratorsгаthat NimгаСФ async macro is based on has been rewritten from the ground up and so async works completely with exception handling. Finally it is possible to use await in a try statement!
Nimble 0.9.0

This release includes a brand new version of Nimble. The new version contains a breaking change which you should read up on if you own hybrid packages. There are also the usual bug fixes and this release contains a lot of them.

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 for more details. You can use substr(str, start, finish) to get the old behaviour back, see this commit for an example.

    strutils.split and strutils.rsplit with an empty string and a separator now returns that empty string. See issue #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 deprecated: use glm, arraymancer, neo, or another package instead
        basic3d deprecated: use glm, arraymancer, neo, or another package instead
        gentabs
        libuv
        polynumeric
        pdcurses
        romans
        libsvm
        joyent_http_parser

    Proc toCountTable 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:

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

    for item in mySeq:
      myCounter.inc item

    Now, you can simply do:

    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 гаЧЗrom backwardsгаlike a[^1] or a[0..^1] are implemented. These are now implemented purely in system.nim without compiler support. There is a new гаЧЙeterogenousгаslice 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:

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

    This now needs to be written as:

    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 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 NimгаСФ 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 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:

    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 canгаСХ 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

    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 doesnгаСХ 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 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:

    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:

    # 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 doesnгаСХ die with an гаЧРut of rangeгаerror anymore:

    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/ 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:

    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.

    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.

    NimгаСФ rst2html command now supports the testing of code snippets via an RST extension that we called :test:::

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


0.17.0:
Changes affecting backwards compatibility

    There are now two different HTTP response types, Response and AsyncResponse. AsyncResponseгаСФ body accessor returns a Future[string]!

    Due to this change you may need to add another await in your code.
    httpclient.request now respects the maxRedirects option. Previously redirects were handled only by get and post procs.
    The IO routines now raise EOFError for the гаЧЖnd of fileгаcondition. EOFError is a subtype of IOError and so itгаСФ easier to distinguish between гаЧЖrror during readгаand гаЧЖrror due to EOFга
    A hash procedure has been added for cstring type in hashes module. Previously, hash of a cstring would be calculated as a hash of the pointer. Now the hash is calculated from the contents of the string, assuming cstring is a null-terminated string. Equal string and cstring values produce an equal hash value.
    Macros accepting varargs arguments will now receive a node having the nkArgList node kind. Previous code expecting the node kind to be nkBracket may have to be updated.
    memfiles.open now closes file handles/fds by default. Passing allowRemap=true to memfiles.open recovers the old behavior. The old behavior is only needed to call mapMem on the resulting MemFile.
    posix.nim: For better C++ interop the field sa_sigaction*: proc (x: cint, y: var SigInfo, z: pointer) {.noconv.} was changed to sa_sigaction*: proc (x: cint, y: ptr SigInfo, z: pointer) {.noconv.}.
    The compiler doesnгаСХ infer effects for .base methods anymore. This means you need to annotate them with .gcsafe or similar to clearly declare upfront every implementation needs to fullfill these contracts.
    system.getAst templateCall(x, y) now typechecks the templateCall properly. You need to patch your code accordingly.
    macros.getType and macros.getTypeImpl for an enum will now return an AST that is the same as what is used to define an enum. Previously the AST returned had a repeated EnumTy node and was missing the initial pragma node (which is currently empty for an enum).
    macros.getTypeImpl now correctly returns the implementation for a symbol of type tyGenericBody.
    If the dispatcher parameterгаСФ value used in multi method is nil, a NilError exception is raised. The old behavior was that the method would be a nop then.
    posix.nim: the family of ntohs procs now takes unsigned integers instead of signed integers.
    In Nim identifiers en-dash (Unicode point U+2013) is not an alias for the underscore anymore. Use underscores instead.
    When the requiresInit pragma is applied to a record type, future versions of Nim will also require you to initialize all the fields of the type during object construction. For now, only a warning will be produced.
    The Object construction syntax now performs a number of additional safety checks. When fields within case objects are initialiazed, the compiler will now demand that the respective discriminator field has a matching known compile-time value.
    On posix, the results of waitForExit, peekExitCode, execCmd will return 128 + signal number if the application terminates via signal.
    ospaths.getConfigDir now conforms to the XDG Base Directory specification on non-Windows OSs. It returns the value of the XDG_CONFIG_DIR environment variable if it is set, and returns the default configuration directory, гаЧЯ/.config/га otherwise.
    Renamed the line info node parameter for newNimNode procedure.

    The parsing rules of do changed.

      foo bar do:
        baz

    Used to be parsed as:

      foo(bar(do:
        baz))

    Now it is parsed as:

      foo(bar, do:
        baz)

Library Additions

    Added system.onThreadDestruction.

    Added dial procedure to networking modules: net, asyncdispatch, asyncnet. It merges socket creation, address resolution, and connection into single step. When using dial, you donгаСХ have to worry about the IPv4 vs IPv6 problem. httpclient now supports IPv6.

    Added to macro which allows JSON to be unmarshalled into a type.

      import json

      type
        Person = object
          name: string
          age: int

      let data = """
        {
          "name": "Amy",
          "age": 4
        }
      """

      let node = parseJson(data)
      let obj = node.to(Person)
      echo(obj)

Tool Additions

    The finish tool can now download MingW for you should it not find a working MingW installation.

Compiler Additions

    The name mangling rules used by the C code generator changed. Most of the time local variables and parameters are not mangled at all anymore. This improves the debugging experience.
    The compiler produces explicit name mangling files when --debugger:native is enabled. Debuggers can read these .ndi files in order to improve debugging Nim code.

Language Additions

    The try statementгаСФ except branches now support the binding of a caught exception to a variable:

        try:
          raise newException(Exception, "Hello World")
        except Exception as exc:
          echo(exc.msg)

    This replaces the getCurrentException and getCurrentExceptionMsg() procedures, although these procedures will remain in the stdlib for the foreseeable future. This new language feature is actually implemented using these procedures.

    In the near future we will be converting all exception types to refs to remove the need for the newException template.
    A new pragma .used can be used for symbols to prevent the гаЧЕeclared but not usedгаwarning. More details can be found here.

    The popular гаЧДolon block of statementsгаsyntax is now also supported for let and var statements and assignments:

      template ve(value, effect): untyped =
        effect
        value

      let x = ve(4):
        echo "welcome to Nim!"

    This is particularly useful for DSLs that help in tree construction.

Language changes

    The .procvar annotation is not required anymore. That doesnгаСХ mean you can pass system.$ to map just yet though.

Update nim from 0.14.2 to 0.16.0

Upstream changelog
==================

Changelog 0.16.0
Changes affecting backwards compatibility

    staticExec now uses the directory of the nim file that contains the staticExec call as the current working directory.
    TimeInfo.tzname has been removed from times module because it was broken. Because of this, the option "ZZZ" will no longer work in format strings for formatting and parsing.

Library Additions

    Added new parameter to error proc of macro module to provide better error message
    Added new deques module intended to replace queues. deques provides a superset of queues API with clear naming. queues module is now deprecated and will be removed in the future.
    Added hideCursor, showCursor, terminalWidth, terminalWidthIoctl and terminalSize to the terminal (doc) module.
    Added new module distros (doc) that can be used in Nimble packages to aid in supporting the OS's native package managers.

Tool Additions
Compiler Additions

    The C/C++ code generator has been rewritten to use stable name mangling rules. This means that compile times for edit-compile-run cycles are much reduced.

Language Additions

    The emit pragma now takes a list of Nim expressions instead of a single string literal. This list can easily contain non-strings like template parameters. This means emit works out of the box with templates and no new quoting rules needed to be introduced. The old way with backtick quoting is still supported but will be deprecated.

type Vector* {.importcpp: "std::vector", header: "<vector>".}[T] = object

template `[]=`*[T](v: var Vector[T], key: int, val: T) =
  {.emit: [v, "[", key, "] = ", val, ";"].}

proc setLen*[T](v: var Vector[T]; size: int) {.importcpp: "resize", nodecl.}
proc `[]`*[T](v: var Vector[T], key: int): T {.importcpp: "(#[#])", nodecl.}

proc main =
  var v: Vector[float]
  v.setLen 1
  v[0] = 6.0
  echo v[0]

    The import statement now supports importing multiple modules from the same directory:

import compiler / [ast, parser, lexer]

Is a shortcut for:

import compiler / ast, compiler / parser, compiler / lexer

Version 0.15.2 released

We're happy to announce that the latest release of Nim, version 0.15.2, is now available!

As always, you can grab the latest version from the downloads page.

This release is a pure bugfix release fixing the most pressing issues and regressions of 0.15.0. For Windows we now provide zipfiles in addition to the NSIS based installer which proves to be hard to maintain and after all these months still has serious issues. So we encourage you download the .zip file instead of the .exe file! Unzip it somewhere, run finish.exe to detect your MingW installation, done. finish.exe can also set your PATH environment variable.

Changelog 0.15.0
Changes affecting backwards compatibility

    The json module now uses an OrderedTable rather than a Table for JSON objects.
    The split (doc) procedure in the strutils module (with a delimiter of type set[char]) no longer strips and splits characters out of the target string by the entire set of characters. Instead, it now behaves in a similar fashion to split with string and char delimiters. Use splitWhitespace to get the old behaviour.

    The command invocation syntax will soon apply to open brackets and curlies too. This means that code like a [i] will be interpreted as a([i]) and not as a[i] anymore. Likewise f (a, b) means that the tuple (a, b) is passed to f. The compiler produces a warning for a [i]:

    Warning: a [b] will be parsed as command syntax; spacing is deprecated

    See Issue #3898 for the relevant discussion.
    Overloading the special operators ., .(), .=, () now needs to be enabled via the {.experimental.} pragma.
    immediate templates and macros are now deprecated. Use untyped (doc) parameters instead.
    The metatype expr is deprecated. Use untyped (doc) instead.
    The metatype stmt is deprecated. Use typed (doc) instead.
    The compiler is now more picky when it comes to tuple types. The following code used to compile, now it's rejected:

import tables
var rocketaims = initOrderedTable[string, Table[tuple[k: int8, v: int8], int64]]()
rocketaims["hi"] = {(-1.int8, 0.int8): 0.int64}.toTable()

Instead be consistent in your tuple usage and use tuple names for named tuples:

import tables
var rocketaims = initOrderedTable[string, Table[tuple[k: int8, v: int8], int64]]()
rocketaims["hi"] = {(k: -1.int8, v: 0.int8): 0.int64}.toTable()

    Now when you compile console applications for Windows, console output encoding is automatically set to UTF-8.
    Unhandled exceptions in JavaScript are now thrown regardless of whether noUnhandledHandler is defined. But the stack traces should be much more readable now.
    In JavaScript, the system.alert procedure has been deprecated. Use dom.alert instead.
    De-deprecated re.nim because there is too much code using it and it got the basic API right.
    The type of headers field in the AsyncHttpClient type (doc) has been changed from a string table to the specialised HttpHeaders type.
    The httpclient.request (doc) procedure which takes the httpMethod as a string value no longer requires it to be prefixed with "http" (or similar).
    Converting a HttpMethod (doc) value to a string using the $ operator will give string values without the "Http" prefix now.
    The Request (doc) object defined in the asynchttpserver module now uses the HttpMethod type for the request method.

Library Additions

    Added readHeaderRow and rowEntry to the parsecsv (doc) module to provide a lightweight alternative to python's csv.DictReader.
    Added setStdIoUnbuffered proc to the system module to enable unbuffered I/O.
    Added center and rsplit to the strutils (doc) module to provide similar Python functionality for Nim's strings.
    Added isTitle, title, swapCase, isUpper, toUpper, isLower, toLower, isAlpha, isSpace, and capitalize to the unicode.nim (doc) module to provide unicode aware case manipulation and case testing.
    Added a new module strmisc (doc) to hold uncommon string operations. Currently contains partition, rpartition and expandTabs.
    Split out walkFiles in the os (doc) module to three separate procs in order to make a clear distinction of functionality. walkPattern iterates over both files and directories, while walkFiles now only iterates over files and walkDirs only iterates over directories.
    Added a synchronous HttpClient in the httpclient (doc) module. The old get, post and similar procedures are now deprecated in favour of it.
    Added a new macro called multisync allowing you to write procedures for synchronous and asynchronous sockets with no duplication.
    The async macro will now complete FutureVar[T] parameters automatically unless they have been completed already.

Tool Additions

    The documentation is now searchable and sortable by type.
    Pragmas are now hidden by default in the documentation to reduce noise.
    Edit links are now present in the documentation.

Compiler Additions

    The -d/--define flag can now optionally take a value to be used by code at compile time. (doc)

Nimscript Additions

    It's possible to enable and disable specific hints and warnings in Nimscript via the warning and hint procedures.
    Nimscript exports a proc named patchFile which can be used to patch modules or include files for different Nimble packages, including the stdlib package.

Language Additions

    Added {.intdefine.} and {.strdefine.} macros to make use of (optional) compile time defines. (doc)
    If the first statement is an import system statement then system is not imported implicitly anymore. This allows for code like import system except echo or from system import nil.

Import nim-0.14.2 as lang/nim

Nim (formerly known as "Nimrod") is a statically typed, imperative
programming language that tries to give the programmer ultimate power
without compromises on runtime efficiency. This means it focuses on
compile-time mechanisms in all their various forms.

Beneath a nice infix/indentation based syntax with a powerful (AST based,
hygienic) macro system lies a semantic model that supports a soft realtime
GC on thread local heaps. Asynchronous message passing is used between
threads, so no "stop the world" mechanism is necessary. An unsafe shared
memory heap is also provided for the increased efficiency that results from
that model.

Originally packaged in pkgsrc-wip by:
 - Christian Koch
 - Roland Illig
and
 - myself.
