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/byaddr`. +- `var a {.foo.}: MyType = expr` now lowers to `foo(a, MyType, expr)` for + non-builtin pragmas, enabling things like lvalue references (see `pragmas.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. + + +## Bugfixes + +- Fixed "`nimgrep --nocolor` is ignored on posix; should be instead: `--nimgrep --color=[auto]|true|false`" + ([#7591](https://github.com/nim-lang/Nim/issues/7591)) +- Fixed "Runtime index on const array (of converted obj) causes C-compiler error" +
