* Mark `macros.error` as `.noreturn.` (#23081)Jake Leahy2023-12-171-1/+6
| | | | | | | | | | | | | | | Closes #14329 Marks `macros.error` as `.noreturn` so that it can be used in expressions. This also fixes the issue that occurred in #19659 where a stmt that could be an expression (Due to having `discardable` procs at the end of other branches) would believe a `noreturn` proc is returning the same type e.g. ```nim proc bar(): int {.discardable.} = discard if true: bar() else: quit(0) # Says that quit is of type `int` and needs to be used/discarded except it actually has no return type ```

* rationals: support Rational[SomeUnsignedInt] (#23046)shirleyquirk2023-12-151-6/+6
| | | | | | | | fixes #22227 rationale: - `3u - 4u` is supported why not`3u.toRational - 4u.toRational` - all of rationals' api is on SomeInteger, looks like unsigned is declared as supported - math on unsigned rationals is meaningful and useful.

* strutils.multiReplace: Making order of replacement explicit (#23022)Joachim Hereth2023-12-021-2/+3
| | | | | | | | | | | | | | | | | | | | | | In the docs for strutils.multiReplace: Making it more explicit that left to right comes before the order in the replacements arg (but that the latter matters too). E.g. ``` echo "ab".multiReplace(@[("a", "1"), ("ax", "2")]) echo "ab".multiReplace(@[("ab", "2"), ("a", "1")]) ``` gives ``` 1b 2 ``` resolves #23016
* related #22534; fixes documentation rendering of custom number literal ↵Erich Reitz2023-12-011-11/+12
| | | | | | | | | | | | | | | routine declaration (#23015) I'm not sure if this is a complete fix, as it does not match the expected output given in the issue. The expected output given in the issue highlights the identifier after the `'` the same color as numeric literals (blue), and this change does not address that. I think that would involve simplifying `nimNumberPostfix`. However, this fixes the issue where the routine declaration was rendered as a string. New rendering: ![Screenshot from 2023-11-30 22-17-17](https://github.com/nim-lang/Nim/assets/80008541/b604ce27-a4ad-496b-82c3-0b568d99a8bf)

* Fix OSError `errorCode` field is not assigned a value (#22954)握猫猫2023-11-175-48/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | In this PR, the following changes were made: 1. Replaced `raise newException(OSError, osErrorMsg(errno))` in batches with `raiseOSError(errcode)`. 2. Replaced `newException(OSError, osErrorMsg(errno))` in batches with `newOSError(errcode)`. There are still some places that have not been replaced. After checking, they are not system errors in the traditional sense. ```nim proc dlclose(lib: LibHandle) = raise newException(OSError, "dlclose not implemented on Nintendo Switch!") ``` ```nim if not fileExists(result) and not dirExists(result): # consider using: `raiseOSError(osLastError(), result)` raise newException(OSError, "file '" & result & "' does not exist") ``` ```nim proc paramStr*(i: int): string = raise newException(OSError, "paramStr is not implemented on Genode") ```
* 'j' format specifier docs (#22928)Angel Ezquerra2023-11-172-5/+11
| | | | | | | | | | | | This is a small improvement on top of PR #22924, which documents the new 'j' format specifier for Complex numbers. In addition to that it moves the handling of the j specifier into the function that actually implements it (formatValueAsComplexNumber), which seems a little cleaner. --------- Co-authored-by: Angel Ezquerra <angel_ezquerra@keysight.com> Co-authored-by: Clay Sweetser <Varriount@users.noreply.github.com>

* Add strformat support for Complex numbers (#22924)Angel Ezquerra2023-11-101-1/+36
| | | | | | | | | | | | | | | | | | | | | Before this change strformat used the generic formatValue function for Complex numbers. This meant that it was not possible to control the format of the real and imaginary components of the complex numbers. With this change this now works: ```nim import std/[complex, strformat] let c = complex(1.05000001, -2.000003) echo &"{c:g}" # You now get: (1.05, -2) # while before you'd get a ValueError exception (invalid type in format string for string, expected 's', but got g) ``` The only small drawback of this change is that I had to import complex from strformat. I hope that is not a problem. --------- Co-authored-by: Angel Ezquerra <angel_ezquerra@keysight.com>
* reserve `sysFatal` for `Defect` (#22158)Jacek Sieka2023-11-064-18/+15
| | | | | | | | Per manual, `panics:on` affects _only_ `Defect`:s - thus `sysFatal` should not redirect any other exceptions. Also, when `sysFatal` is used in `nimPanics` mode, it should use regular exception handling pipeline to ensure exception hooks are called consistently for all raised defects.

* Fix #22862 - change the httpclient user-agent to be valid spec-wise (#22882)Yardanico2023-10-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per https://datatracker.ietf.org/doc/html/rfc9110#name-user-agent a User-Agent is defined as follows: ``` User-Agent = product *( RWS ( product / comment ) ) ``` Where ``` product = token ["/" product-version] product-version = token ``` In this case, `token` is defined in RFC 7230 - https://datatracker.ietf.org/doc/html/rfc7230#section-3.2.6: ``` token = 1*tchar tchar = "!" / "#" / "$" / "%" / "&" / "'" / "*" / "+" / "-" / "." / "^" / "_" / "`" / "|" / "~" / DIGIT / ALPHA ; any VCHAR, except delimiters ``` or, in the original RFC 2616 - https://datatracker.ietf.org/doc/html/rfc2616#section-2.2 (next page): ``` token = 1*<any CHAR except CTLs or separators> separators = "(" | ")" | "<" | ">" | "@" | "," | ";" | ":" | "\" | <"> | "/" | "[" | "]" | "?" | "=" | "{" | "}" | SP | HT ``` which means that a `token` cannot have whitespace. Not sure if this should be in the breaking changelog section - theoretically, some clients might've relied on the old Nim user-agent? For some extra info, some other languages seem to have adopted the same hyphen user agent to specify the language + module, e.g.: - https://github.com/python/cpython/blob/main/Lib/urllib/request.py#L1679 (`Python-urllib/<version>`) Fixes #22862.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Theoretical Benefits / Plans: - Typed assembler-like language. - Allows for a CPS transformation. - Can replace the existing C backend by a new C backend. - Can replace the VM. - Can do more effective "not nil" checking and static array bounds checking. - Can be used instead of the DFA. - Easily translatable to LLVM. - Reasonably easy to produce native code from. - Tiny memory consumption. No pointers, no cry. **In very early stages of development.** Todo: - [x] Map Nim types to IR types. - [ ] Map Nim AST to IR instructions: - [x] Map bitsets to bitops. - [ ] Implement string cases. - [ ] Implement range and index checks. - [x] Implement `default(T)` builtin. - [x] Implement multi string concat. - [ ] Write some analysis passes. - [ ] Write a backend. - [x] Integrate into the compilation pipeline.
