* Add `doctype: RST|Markdown|RstMarkdown` pragma (#20252)Andrey Makarov2022-08-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | * Add `doctype: RST|Markdown|RstMarkdown` pragma Implements https://github.com/nim-lang/RFCs/issues/68 , see also discussion in https://github.com/nim-lang/Nim/issues/17987 The permitted values: * `markdown`, which is default. It still contains nearly all of the RST supported but it is assumed that in time we will give up most or all RST features in this mode * `rst`, without any extensions * `RstMarkdown` — compatibility with Nim 1.x. It's basically RST with those Markdown features enabled that don't conflict with RST. * Apply suggestions from code review Co-authored-by: Clay Sweetser <Varriount@users.noreply.github.com> * Additional fix in spirit of review * Fix test after #20188 Co-authored-by: Clay Sweetser <Varriount@users.noreply.github.com>

* Add use of Windows Wide CRT API for env. vars (#20084)havardjohn2022-08-203-38/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add use of Windows Wide CRT API for env. vars Replaces use of CRT API `getenv` and `putenv` with respectively `_wgetenv` and `_wputenv`. Motivation is to reliably convert environment variables to UTF-8, and the wide API is best there, because it's reliably UTF-16. Changed the hack in `lib/std/private/win_setenv.nim` by switching the order of the Unicode and MBCS environment update; Unicode first, MBCS second. Because `_wgetenv`/`_wputenv` is now used, the Unicode environment will be initialized, so it should always be updated. Stop updating MBCS environment with the name of `getEnv`. It's not necessarily true that MBCS encoding and the `string` encoding is the same. Instead convert UTF-16 to current Windows code page with `wcstombs`, and use that string to update MBCS. Fixes regression in `6b3c77e` that caused `std/envvars.getEnv` or `std/os.getEnv` on Windows to return non-UTF-8 encoded strings. Add tests that test environment variables with Unicode characters in their name or value. * Fix test issues Fixes * `nim cpp` didn't compile the tests * Nimscript import of `tosenv.nim` from `test_nimscript.nims` failed with "cannot importc" * Fix missing error check on `wcstombs` * Fix ANSI testing errors * Separate ANSI-related testing to their own tests, and only executing them if running process has a specific code page * Setting locale with `setlocale` was not reliable and didn't work on certain machines * Add handling of a "no character representation" error in second `wcstombs` call * tests/newruntime_misc: Increment allocCount Increments overall allocations in `tnewruntime_misc` test. This is because `getEnv` now does an additional allocation: allocation of the UTF-16 string used as parameter to `c_wgetenv`. * Revert "tests/newruntime_misc: Increment allocCount" This reverts commit 4d4fe8bd3edb1bfc6d600f247af797c7552f5477. * tests/newruntime_misc: Increment allocCount on Windows Increments overall allocations in `tnewruntime_misc` test for Windows.

* make implicit cstring conversions explicit (#19488)ee72022-08-1911-50/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Nim manual says that an implicit conversion to cstring will eventually not be allowed [1]: A Nim `string` is implicitly convertible to `cstring` for convenience. [...] Even though the conversion is implicit, it is not *safe*: The garbage collector does not consider a `cstring` to be a root and may collect the underlying memory. For this reason, the implicit conversion will be removed in future releases of the Nim compiler. Certain idioms like conversion of a `const` string to `cstring` are safe and will remain to be allowed. And from Nim 1.6.0, such a conversion triggers a warning [2]: A dangerous implicit conversion to `cstring` now triggers a `[CStringConv]` warning. This warning will become an error in future versions! Use an explicit conversion like `cstring(x)` in order to silence the warning. However, some files in this repo produced such a warning. For example, before this commit, compiling `parsejson.nim` would produce: /foo/Nim/lib/pure/parsejson.nim(221, 37) Warning: implicit conversion to 'cstring' from a non-const location: my.buf; this will become a compile time error in the future [CStringConv] /foo/Nim/lib/pure/parsejson.nim(231, 39) Warning: implicit conversion to 'cstring' from a non-const location: my.buf; this will become a compile time error in the future [CStringConv] This commit resolves the most visible `CStringConv` warnings, making the cstring conversions explicit.

* Pass check condition directly to if (#20217)Dan Rose2022-08-151-2/+6
| | | | | | | | | | | | | | | | | | When checking conditions, pass `check` untyped argument directly to if. This results in better error messages when the condition is malformed. Previously `check 1` would fail at compile time with `Error: type mismatch: got 'int literal(-2)' for '-2' but expected 'bool'` Now it fails with `Error: type mismatch: got 'int literal(1)' for '1' but expected 'bool'`. Similarly `check "foo"` would fail with ``` Error: type mismatch: got <string> but expected one of: proc `not`(a: typedesc): typedesc first type mismatch at position: 1 required type for a: typedesc but expression '"somestring"' is of type: string ... ``` Now it fails with `Error: type mismatch: got 'string' for '"somestring"' but expected 'bool'`

* fix broken runnableExamples for getWeeksInIsoYear (#20193)metagn2022-08-111-2/+2
| | | | | Based on what I understand from [Wikipedia](https://en.wikipedia.org/wiki/ISO_week_date#Weeks_per_year), 2001 does not have 53 weeks, but 2004, 2009, 2015, 2020 do. The years 2000 and 2001 seem to be copy pasted from the `getDaysInYear` example above. The result of `getWeeksInIsoYear` also seem to match up with Wikipedia. That means these runnableExamples were never tested. Why is this the case? I only discovered this in #20091.

* Improve Markdown code blocks & start moving docs to Markdown style (#19954)Andrey Makarov2022-07-152-36/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - add additional parameters parsing (other implementations will just ignore them). E.g. if in RST we have: .. code:: nim :test: "nim c $1" ... then in Markdown that will be: ```nim test="nim c $1" ... ``` - implement Markdown interpretation of additional indentation which is less than 4 spaces (>=4 spaces is a code block but it's not implemented yet). RST interpretes it as quoted block, for Markdown it's just normal paragraphs. - add separate `md2html` and `md2tex` commands. This is to separate Markdown behavior in cases when it diverges w.r.t. RST significantly — most conspicously like in the case of additional indentation above, and also currently the contradicting inline rule of Markdown is also turned on only in `md2html` and `md2tex`. **Rationale:** mixing Markdown and RST arbitrarily is a way to nowhere, we need to provide a way to fix the particular behavior. Note that still all commands have **both** Markdown and RST features **enabled**. In this PR `*.nim` files can be processed only in Markdown mode, while `md2html` is for `*.md` files and `rst2html` for `*.rst` files. - rename `*.rst` files to `.*md` as our current default behavior is already Markdown-ish - convert code blocks in `docgen.rst` to Markdown style as an example. Other code blocks will be converted in the follow-up PRs - fix indentation inside Markdown code blocks — additional indentation is preserved there - allow more than 3 backticks open/close blocks (tildas \~ are still not allowed to avoid conflict with RST adornment headings) see also https://github.com/nim-lang/RFCs/issues/355 - better error messages - (other) fix a bug that admonitions cannot be used in sandbox mode; fix annoying warning on line 2711
