This commit reduces the code surface that interacts with raw JSON data,
reducing code complexity and improving maintainability.
Files that needed to be changed drastically were additionally
cleaned up to remove any code cruft that has accrued over time.
In order to facility this the following changes were made:
* Move JSON handling from `CascadiaSettings` into `SettingsLoader`
This allows us to use STL containers for data model instances.
For instance profiles are now added to a hashmap for O(1) lookup.
* JSON parsing within `SettingsLoader` doesn't differentiate between user,
inbox and fragment JSON data, reducing code complexity and size.
It also centralizes common concerns, like profile deduplication and
ensuring that all profiles are assigned a GUID.
* Direct JSON modification, like the insertion of dynamic profiles into
settings.json were removed. This vastly reduces code complexity,
but unfortunately removes support for comments in JSON on first start.
* `ColorScheme`s cannot be layered. As such its `LayerJson` API was replaced
with `FromJson`, allowing us to remove JSON-based color scheme validation.
* `Profile`s used to test their wish to layer using `ShouldBeLayered`, which
was replaced with a GUID-based hashmap lookup on previously parsed profiles.
Further changes were made as improvements upon the previous changes:
* Compact the JSON files embedded binary, saving 28kB
* Prevent double-initialization of the color table in `ColorScheme`
* Making `til::color` getters `constexpr`, allow better optimizations
The result is a reduction of:
* 48kB binary size for the Settings.Model.dll
* 5-10% startup duration
* 26% code for the `CascadiaSettings` class
* 1% overall code in this project
Furthermore this results in the following breaking changes:
* The long deprecated "globals" settings object will not be detected and no
warning will be created during load.
* The initial creation of a new settings.json will not produce helpful comments.
Both cases are caused by the removal of manual JSON handling and the
move to representing the settings file with model objects instead
## PR Checklist
* [x] Closes#5276
* [x] Closes#7421
* [x] I work here
* [x] Tests added/passed
## Validation Steps Performed
* Out-of-box-experience is identical to before ✔️
(Except for the settings.json file lacking comments.)
* Existing user settings load correctly ✔️
* New WSL instances are added to user settings ✔️
* New fragments are added to user settings ✔️
* All profiles are assigned GUIDs ✔️
This adds "paste filtering" & "bracketed paste mode" to the Windows
Terminal.
I've moved the paste handling code in `TerminalControl` to
`Microsoft::Console::Util` to be able to easily test it, and the paste
transformer from `TerminalControl` to `TerminalCore`.
Supersedes #7508
References #395 (overall bracketed paste support request)
Tests added. Manually tested.
* Correct the behaviour of parsing `rgb:R/G/B`. It should be interpreted
as `RR/GG/BB` instead of `0R/0G/0B`
* Add support for `rgb:RRR/GGG/BBB` and `rgb:RRRR/GGGG/BBBB`. The
behaviour of 12 bit variants is to repeat the first digit at the end,
e.g. `rgb:123/456/789` becomes `rgb:1231/4564/7897`.
* Add support for `#` formats. We are following the rules of
[XParseColor] by interpreting `#RGB` as `R000G000B000`.
* Add support for XOrg app color names, which are supported by xterm, VTE
and many other terminal emulators.
* Multi-parameter OSC 4 is now supported.
* The chaining of OSC 10-12 is not yet supported. But the parameter
validation is relaxed by parsing the parameters as multi-params but
only use the first one, which means `\e]10;rgb:R/G/B;` and
`\e]10:rgb:R/G/B;invalid` will execute `OSC 10` with the first color
correctly. This fixes some of the issues mentioned in #942 but not
all of them.

The recent changes to use gsl::span everywhere added a few bounds checks
along codepaths where we were already checking bounds. Some of them may
be non-obvious to the optimizer, so we can now use til::at to help them
along.
To accomplish this, I've added a new overload of til::at that takes a
span and directly accesses its backing buffer.
This results in smaller code and faster copying. I chose til::color even
though it results in slightly worse codegen (byteswapping in a tight
loop) than COLORREF (SSE-enlightened block copy) because eventually the
internal representations of the color tables will also be til::color and
_then_ it will become a block copy.
GSL 3, the next major version of GSL after the one we're using, replaced
their local implementation of `span` with one that more closely mimics
C++20's span. Unfortunately, that is a breaking change for all of GSL's
consumers.
This commit updates our use of span to comply with the new changes in
GSL 3.
Chief among those breaking changes is:
* `span::at` no longer exists; I replaced many instances of `span::at`
with `gsl::at(x)`
* `span::size_type` has finally given up on `ptrdiff_t` and become
`size_t` like all other containers
While I was here, I also made the following mechanical replacements:
* In some of our "early standardized" code, we used std::optional's
`has_value` and `value` back-to-back. Each `value` incurs an
additional presence test.
* Change: `x.value().member` -> `x->member` (`optional::operator->`
skips the presence test)
* Change: `x.value()` -> `*x` (as above)
* GSL 3 uses `size_t` for `size_type`.
* Change: `gsl::narrow<size_t>(x.size())` -> `x.size()`
* Change: `gsl::narrow<ptrdiff_t>(nonSpan.size())` -> `nonSpan.size()`
during span construction
I also replaced two instances of `x[x.size() - 1]` with `x.back()` and
one instance of a manual array walk (for comparison) with a direct
comparison.
NOTE: Span comparison and `make_span` are not part of the C++20 span
library.
Fixes#6251
There is a range of 216 colors in the default 256-color table that is
meant to be initialized with a 6x6x6 color cube, with each color
component iterating over the values `00`, `5F`, `87`, `AF`, `D7`, and
`FF`. A few of the entries incorrectly had the _red_ component has `DF`,
when it should have been `D7`. This PR corrects those entries. It also
removes a bit of unnecessary whitespace in the first 100 entries.
## Validation Steps Performed
I have a visual test script that renders the full 256-color palette,
using both the indexed color sequence (`SGR 38;5`) and the equivalent
rgb representation (`SGR 38;2`) side by side. Although the difference
was subtle when it was incorrect, I can now see that it has been fixed.
Closes#5994
This pull request moves swaths of Cascadia to use `til::color` for color
interop. There are still some places where we use `COLORREF`, such as in
the ABI boundaries between WinRT components.
I've also added two more til::color helpers - `with_alpha`, which takes
an existing color and sets its alpha component, and a
`Windows::UI::Color` convertor pair.
Future direction might include a `TerminalSettings::Color` type at the
idl boundary so we can finally stop using UInt32s (!) for color.
## Validation Steps Performed
Tested certain fragile areas:
* [x] setting the background with OSC 11
* [x] setting the background when acrylic is in use (which requires
low-alpha)
## Summary of the Pull Request
Currently, the program crashes with a window width or height greater than 32767 (accounting for window decorations). This can be caused when the `initialRows` and `initialColumns` settings are set too high (also depends on the font width and height). This fixes the issue by not allowing the window to expand beyond 32767x32767.

#843 - relocated the ClampToShortMax helper for reuse elsewhere
Switch to using jsoncpp as our json library. This lets us pretty-print the json file by default, and lets users place comments in the json file.
We will now only re-write the file when the actual logical structure of the json object changes, not only when the serialization changes.
Unfortunately, this will remove any existing ordering of profiles, and make the order random. We don't terribly care though, because when #754 lands, this will be less painful.
It also introduces a top-level globals object to hold all the global properties, including keybindings. Existing profiles should gracefully upgrade.
This commit switches the GUIDs for default profiles from being randomly generated to being version 5 UUIDs. More info in #870.

## Detailed Description of the Pull Request / Additional comments
This commit has a number of changes that seem ancillary, but they're general goodness. Let me explain:
* I've added a whole new Types test library with only two tests in
* Since UUIDv5 generation requires SHA1, we needed to take a dependency on bcrypt
* I honestly don't think we should have to link bcrypt in conhost, but LTO should take care of that
* I considered adding a new Terminal-specific Utils/Types library, but that seemed like a waste
* The best way to link bcrypt turned out to be in line with a discussion @miniksa and I had, where we decided we both love APISets and think that the console should link against them exclusively... so I've added `onecore_apiset.lib` to the front of the link line, where it will deflect the linker away from most of the other libs automagically.
