This commit removes our local copy of clang-format 8 and replaces it
with a newly-built nuget package containing clang-format 10.
This resolves the inconsistency between our version of clang-format and
the one shipped in Visual Studio.
A couple minor format changes were either required or erroneously forced
upon us--chief among them is a redistribution of `*`s around SAL
annotations in inline class members of COM classes. Don't ask why; I
couldn't figure it out.
We had some aspirational goals for our formatting, which were left in
but commented out. Enabling them changes our format a little more than
I'm comfortable with, so I uncommented them and locked them to the
format style we've been using for the past year. We may not love it, but
our aspirations may not matter here any longer. Consistent formatting is
better than perfect formatting.
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
## Summary of the Pull Request
When resizing the window title, a GDI object would be leaked. This has to do with our island message handler using `wil` to track these objects and `wil` having a bug.

## PR Checklist
* [x] Closes#5949
* [x] I work here.
* [x] Tested manually
* [x] Doc not required.
* [x] Am core contributor.
## Validation Steps Performed
* [x] Added the GDI Objects column to Task Manager, set the Terminal to use the `titleWidth` size tabs, then changed the title a bunch with PowerShell. Confirmed repro before (increasing GDI count). Confirmed it's gone after (no change to object count).
This change is necessary as the dep/ folder is not synced into the
Windows source tree.
I've also added a build rule producing a lib for {fmt}.
This will be required for our next OS ingestion.
We received a request from our localization team to switch from
printf-style format strings (%s, %u) to format strings with positional
argument support. I've been hoping for a long time to take a dependency
on C++20's std::format, but we're just not somewhere we can do that.
Enter fmt. fmt is _exactly_ the library we need.
Minor comparison:
std::wstring_view world = /* ... */;
auto str{ wil::str_printf<std::wstring>(L"hello %.*s",
gsl::narrow_cast<size_t>(world.size()),
world.data()) };
---
auto str{ fmt::format(L"hello {0}", world) };
If you really want to use the print specifiers:
auto str{ fmt::printf(L"hello %s", world) };
It's got optional compile-time checking for format strings and is
MIT-licensed. Eventually, we should be able to replace fmt:: with std::
and end up pretty much where we left off.
What more could you ask for?
This commit replaces `std::vector<bool>` with `dynamic_bitset<>` by
@pinam45 (https://github.com/pinam45/dynamic_bitset) and with
`libpopcnt` for high-performance bit counting by @kimwalisch
(https://github.com/kimwalisch/libpopcnt).
* [x] In support of performance, incremental rendering, and Terminal
"not speed enough" as well as my sanity relative to
`std::vector<bool>`
* [x] Tests updated and passed.
* [x] `LICENSE`, `NOTICE`, and provenance files updated.
* [x] I'm a core contributor. I discussed it with @DHowett-MSFT and
cleared the licensing checks before pulling this in.
## Details `std::vector<bool>` provided by the Microsoft VC Runtime is
incapable of a great many things. Many of the methods you come to expect
off of `std::vector<T>` that are dutifully presented through the `bool`
variant will spontaneously fail at some future date because it decides
you allocated, resized, or manipulated the `vector<bool>` specialization
in an unsupported manner. Half of the methods will straight up not work
for filling/resizing in bulk. And you will tear your hair out as it will
somehow magically forget the assignment of half the bits you gave it
part way through an iteration then assert out and die.
As such, to preserve my sanity, I searched for an alternative. I came
across the self-contained header-only library `dynamic_bitset` by
@pinam45 which appears to do as much of `boost::dynamic_bitset` as I
wanted, but without including 400kg of boost libraries. It also has a
nifty optional dependency on `libpopcnt` by @kimwalisch that will use
processor-specific extensions for rapidly counting bits. @DHowett-MSFT
and I briefly discussed how nice `popcnt` would have been on
`std::vector<bool>` last week... and now we can have it. (To be fair, I
don't believe I'm using it yet... but we'll be able to easily dial in
`til::bitmap` soon and not worry about a performance hit if we do have
to walk bits and count them thanks to `libpopcnt`.)
This PR specifically focuses on swapping the dependencies out and
ingesting the new libraries. We'll further tune `til::bitmap` in future
pulls as necessary.
## Validation
* [x] Ran the automated tests for bitmap.
* [x] Ran the terminal manually and it looks fine still.
This commit upgrades C++/WinRT to 2.0.200316.3 and fixes a couple of the
transitive dependency issues we had in the process.
Because the latest version has better dependency resolution, we're able
to properly depend on Microsoft.UI.Xaml and the Toolkit in TerminalApp
and TerminalAppLib so we no longer need to manually include .dll and
.pri files.
Because of nebulous _other_ changes in dependency resolution,
WindowsTerminalUniversal isn't picking up transitive .winmd dependencies
from TerminalApp, and needs to include them as ProjectReferences
directly. This was already happening transitively, so now it's explicit.
I've also taken the time to upgrade GSL to v2.1.0, the last release
before they removed span::at and blew up our world.
## Summary of the Pull Request
Adds support for commandline arguments to the Windows Terminal, in accordance with the spec in #3495
## References
* Original issue: #607
* Original spec: #3495
## PR Checklist
* [x] Closes#607
* [x] I work here
* [x] Tests added/passed
* [ ] We should probably add some docs on these commands
* [x] The spec (#3495) needs to be merged first!
## Detailed Description of the Pull Request / Additional comments
🛑 **STOP** 🛑 - have you read #3495 yet? If you haven't, go do that now.
This PR adds support for three initial sub-commands to the `wt.exe` application:
* `new-tab`: Used to create a new tab.
* `split-pane`: Used to create a new split.
* `focus-tab`: Moves focus to another tab.
These commands are largely POC to prove that the commandlines work. They're not totally finished, but they work well enough. Follow up work items will be filed to track adding support for additional parameters and subcommands
Important scenarios added:
* `wt -d .`: Open a new wt instance in the current working directory #878
* `wt -p <profile name>`: Create a wt instance running the given profile, to unblock #576, #1357, #2339
* `wt ; new-tab ; split-pane -V`: Launch the terminal with multiple tabs, splits, to unblock #756
## Validation Steps Performed
* Ran tests
* Played with it a bunch

## Validation Steps Performed
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.
