This pull request brings us up to fmt 11.1.4 and enables `FMT_PEDANTIC`.
`FMT_PEDANTIC` turns on `/W3`, which is required by our local feudal
lords who will automatically file bugs on us if we don't build with
enough warnings enabled.
This adds support to the Terminal for parsing Markdown to XAML. We're
using https://github.com/github/cmark-gfm as our parser, so that we can
support the fullness of github-flavored markdown.
The parser parses the markdown to produce a `RichTextBlock`, which
covers just about all the scenarios we need. Since we're initially just
targeting using this for "Release notes", I didn't implement
_everything_ in markdown[^1]. But headers, bold & italic, unordered
lists, images, links, code spans & blocks - all that works. We can work
on additional elements as we need them. The parser is encapsulated into
`Microsoft.Terminal.UI.Markdown.dll`, so that we won't load it on
startup, only when the pane is actually made the first time.
To test this out, I've added a `MarkdownPaneContent` pane type on
`x-markdown` (the `x-` is "experimental"). Go ahead and add that with:
```json
{ "command": { "action": "splitPane", "type": "x-markdown" } }
```
That's got the ability to load arbitrary MD files and render them. I
wouldn't call that experience finished though[^2][^3](and it probably
won't be in 1.22 timeframe). However, it is an excellent testbed for
validating what we do and do not support.
We'll use the markdown parser Soon<sup>TM</sup> for the What's New
panes.
* Done in pursuit of displaying release notes in the Terminal.
* Doesn't quite close out #16495
* Should make #8647 possible
* may help with #16484
[^1]: the most notable gap being "block quotes" with `>`. I don't think
I can draw a vertical line in a rich text block easily. Footnotes are
also missing, as well as tables.
[^2]: I say it's not finished because the aforementioned MD gaps. Also
the UX there is not polished at all.
[^3]: I don't believe we'll have time to polish out the pure markdown
pane for 1.22, but what the parser covers now is more than enough for
the release notes pane in time for 1.22
Between fmt 7.1.3 and 11.0.2 a lot has happened. `wchar_t` support is
now more limited and implicit conversions don't work anymore.
Furthermore, even the non-`FMT_COMPILE` API is now compile-time checked
and so it fails to work in our UI code which passes `hstring` format
strings which aren't implicitly convertible to the expected type.
`fmt::runtime` was introduced for this but it also fails to work for
`hstring` parameters. To solve this, a new `RS_fmt` macro was added
to abstract the added `std::wstring_view` casting away.
Finally, some additional changes to reduce `stringstream` usage
have been made, whenever `format_to`, etc., is available.
This mostly affects `ActionArgs.cpp`.
Closes#16000
## Validation Steps Performed
* Compiles ✅
* Settings page opens ✅
This pull request removes the following vendored open source, in favor
of getting it from vcpkg:
- CLI11 2.4
- jsoncpp 1.9
- fmt 7.1.3
- gsl 3.1 (not vendored, but submoduled--arguably worse!)
Now that Visual Studio 2022 includes a built-in workload for vcpkg, the
onboarding process is much smoother. Terminal should only require the
vcpkg workload.
I've added some build rules that detect vcpkg via VS and via the user's
environment before falling back to a location in the source tree. The CI
pipeline will fall back to installing and bootstrapping vcpkg in
dep/vcpkg if necessary.
Some OSS has not been (and will not be) migrated:
- wyhash: ours is included directly in til/hash
- pcg_random: we have a stripped down copy compared to vcpkg
- stb_rect: vcpkg only ships *all of STB*; ours is a stripped down copy
- chromium numerics: vcpkg does not ship Chromium, especially not this
tiny fraction of Chromium
- dynamic_bitset and libpopcnt: removing in #17510
- interval_tree: no vcpkg equivalent
To support the needs of the inbox Windows build, I've split up our vcpkg
manifest into dependencies for all projects and dependencies just for
Terminal. To support this, we now offer a `terminal` feature. The vcpkg
rules in `common.build.pre.props` are set up to turn it on, whereas the
build rules we eventually write for the OS will not be.
Most of the work is concentrated in `common.build.pre.props`.
