Mike Griese 734fc1dcc6 Don't copy text if there's no selection (#2446)
This commit also transitions our keybinding events and event handlers to a
TypedEventHandler model with an "event args" class, as specified in the
keybinding arguments specification (#1349). In short, every event can be marked
Handled independently, and a Handled event will stop bubbling out to the
terminal. An unhandled event will be passed off to the terminal as a standard
keypress.

This unifies our keybinding event model and provides a convenient place for
binding arguments to live.

Fixes #2285.
Related to #1349, #1142.

Replace CodepointWidthDetector's runtime table with a static one (#2368)
This commit replaces CodepointWidthDetector's
dynamically-generated map with a static constexpr one that's compiled
into the binary.

It also almost totally removes the notion of an `Invalid` width. We
definitely had gaps in our character coverage where we'd report a
character as invalid, but we'd then flatten that down to `Narrow` when
asked. By combining the not-present state and the narrow state, we get
to save a significant chunk of data.

I've tested this by feeding it all 0x10FFFF codepoints (and then some)
and making sure they 100% match the old code's outputs.

|------------------------------|---------------|----------------|
| Metric                       | Then          | Now            |
|------------------------------|---------------|----------------|
| disk space                   | 56k (`.text`) | 3k (`.rdata`)  |
| runtime memory (allocations) | 1088          | 0              |
| runtime memory (bytes)       | 51k           | ~0             |
| memory behavior              | not shared    | fully shared   |
| lookup time                  | ~31ns         | ~9ns           |
| first hit penalty            | ~170000ns     | 0ns            |
| lines of code                | 1088          | 285            |

Carlos Zamora 1f41fd35cf Chunk Selection Expansion for Double/Triple Click Selection (#2184)
Double/Triple click create a selection expanding beyond one cell. This PR makes it so that when you're dragging your mouse to expand the selection, you expand to the next delimiter defined by double/triple click.

So, double click expands by doubleClickDelimiter ranges. Triple click expands by line.

When you double/triple click, a word/line is selected. When you drag, that word/line will remain selected after the expansion occurs.

Closes #1933 

## Details
Rather than resizing the selection when the mouse event occurs, I figured I'd do what I did with wide glyph selection: expand at render time.

We needed an enum `multiClickSelectionMode` to keep track of which expansion mode we're in.

Minor modifications to `_ExpandDoubleClickSelection*(COORD)` had to be made so that we can re-use them. 

Actual expansion occurs in `_GetSelectionRects()`

## Validation Steps Performed
- generic double click test
  - `dir` or `ls`
  - double click a word
  - drag up
  - Works! ✔
- double click on delimiter test
  - `dir` or `ls`
  - double click a word delimiter (i.e.: space between words)
  - drag up
  - Works! ✔
- generic triple click test
  - `dir` or `ls`
  - triple click a line
  - drag up
  - Works! ✔
- ALT + double click test
  - `dir` or `ls`
  - hold ALT
  - double click a word
  - drag up
  - Works! ✔

repeat above tests in following scenarios:
- when at top of scrollback
- drag down instead of up

Mike Griese 82de43bce9 A better fix for #tab-titles-are-too-long (#2373)
### User Stories:

1. A user wants to be able to use the executable path as their starting title
    - Does anyone want this?
2. A user wants to be able to set a custom starting title, but have that title be overridable
3. A user wants to be able to set an overridable starting title, different from the profile name
    - Presumably someone will want this
4. A user totally wants to ignore the VT title and use something else
    - This will make more sense in the post [#1320] "Support runtime variables in the custom user title" settings

### Solutions:

1. `name`, `startingTitle`, `tabTitle`
    * a. `name` is only ever used as the profile name.
    * b. If `startingTitle` isn't set, then the executable path is used
    * c. If `startingTitle` is set, it's used as the initial title
    * d. If `tabTitle` is set, it overrides the title from the terminal
    * e. Current users of `tabTitle` need to manually update to the new behavior.
2. `name` as starting title, `tabTitle` as a different starting title
    * a. `name` is used as the starting title and the profile name in the dropdown
    * b. If `tabTitle` is set, we'll use that as the overridable starting title instead.
    * c. In the future, `dynamicTabTitle` or `tabTitleOverride` could be added to support [#1320]
    * d. Current users of `tabTitle` automatically get the new (different!) behavior.
    * e. User Story 1 is impossible
        - Does anyone want the behavior _ever_? Perhaps making that scenario impossible is good?
3. `name` unchanged, `tabTitle` as the starting title
    * a. `name` is only ever used as the profile name.
    * b. If `tabTitle` is set, we'll use that as the overridable starting title.
    * c. In the future, `dynamicTabTitle` or `tabTitleOverride` could be added to support [#1320]
    * d. Current users of `tabTitle` automatically get the new (different!) behavior.
4. `name` as starting title, `tabTitle` as different starting title, `suppressApplicationTitle` Boolean to force it to override
    * a. `name`, `tabTitle` work as in Solution 2.
    * b. When someone wants to be able to statically totally override that title (story 4), they can use `suppressApplicationTitle`
    * c. `suppressApplicationTitle` name is WIP
    * d.  We'll add `suppressApplicationTitle` when someone complains
    * e. If you really want story 1, use `tabTitle: c:\path\to\foo.exe` and `suppressApplicationTitle`.

[#1320]: https://github.com/microsoft/terminal/issues/1320

We've decided to pursue path 4.

Add a Local Test binary, to enable local TerminalApp testing (#2294)
In #1164 we learned that our CI doesn't support WinRT testing. This made us all sad. Since that merged, we haven't really added any TerminalApp tests, because it's a little too hard. You'd have to uncomment the entire file, and if the list of types changed you'd have to manually update the sxs manifest and appxmanifest.

Since that was all insane, I created a new Terminal App unittesting project without those problems.
1. The project is not named *Unit*Test*, so the CI won't run it, but it will run locally.
2. The project will auto-generate its SxS manifest, using the work from #1987. 
3. We'll use the SxS manifest from step 2 to generate an AppxManifest for running packaged tests.


* This is the start of me trying to enable local unittesting again

  * We've got a new unittests project that isn't named *unit*test*

  * We're manually generating the SxS manifest for it. B/C we need to use it at runtime, we need to manually combine it into one manifest file

  * the runas:UAP thing still doesn't work. We'll investigate.

* This shockingly works

but I'm still stuck with:
```
Summary of Errors Outside of Tests:
Error: TAEF: [HRESULT: 0x80270254] Failed to create the test host process for
out of process test execution. (The
IApplicationActivationManager::ActivateApplication call failed while using a
default host. TAEF's ETW logs which are gathered with the /enableEtwLogging
switch should contain events from relevant providers that may help to diagnose
the failure.)
```

* Cleaning this all up for review.

  Frankly just pushing to see if it'll work in CI

Carlos Zamora a08666b58e Accessibility: TermControl Automation Peer (#2083)
Builds on the work of #1691 and #1915 

Let's start with the easy change:
- `TermControl`'s `controlRoot` was removed. `TermControl` is a `UserControl`
  now.

Ok. Now we've got a story to tell here....

### TermControlAP - the Automation Peer
Here's an in-depth guide on custom automation peers:
https://docs.microsoft.com/en-us/windows/uwp/design/accessibility/custom-automation-peers

We have a custom XAML element (TermControl). So XAML can't really hold our
hands and determine an accessible behavior for us. So this automation peer is
responsible for enabling that interaction.

We made it a FrameworkElementAutomationPeer to get as much accessibility as
possible from it just being a XAML element (i.e.: where are we on the screen?
what are my dimensions?). This is recommended. Any functions with "Core" at the
end, are overwritten here to tweak this automation peer into what we really
need.

But what kind of interactions can a user expect from this XAML element?
Introducing ControlPatterns! There's a ton of interfaces that just define "what
can I do". Thankfully, we already know that we're supposed to be
`ScreenInfoUiaProvider` and that was an `ITextProvider`, so let's just make the
TermControlAP an `ITextProvider` too.

So now we have a way to define what accessible actions can be performed on us,
but what should those actions do? Well let's just use the automation providers
from ConHost that are now in a shared space! (Note: this is a great place to
stop and get some coffee. We're about to hop into the .cpp file in the next
section)


### Wrapping our shared Automation Providers

Unfortunately, we can't just use the automation providers from ConHost. Or, at
least not just hook them up as easily as we wish. ConHost's UIA Providers were
written using UIAutomationCore and ITextRangeProiuder. XAML's interfaces
ITextProvider and ITextRangeProvider are lined up to be exactly the same.

So we need to wrap our ConHost UIA Providers (UIAutomationCore) with the XAML
ones. We had two providers, so that means we have two wrappers.

#### TermControlAP (XAML) <----> ScreenInfoUiaProvider (UIAutomationCore)
Each of the functions in the pragma region `ITextProvider` for
TermControlAP.cpp is just wrapping what we do in `ScreenInfoUiaProvider`, and
returning an acceptable version of it.

Most of `ScreenInfoUiaProvider`'s functions return `UiaTextRange`s. So we need
to wrap that too. That's this next section...

#### XamlUiaTextRange (XAML) <----> UiaTextRange (UIAutomationCore)
Same idea.  We're wrapping everything that we could do with `UiaTextRange` and
putting it inside of `XamlUiaTextRange`.


### Additional changes to `UiaTextRange` and `ScreenInfoUiaProvider`
If you don't know what I just said, please read this background:
- #1691: how accessibility works and the general responsibility of these two
  classes
- #1915: how we pulled these Accessibility Providers into a shared area

TL;DR: `ScreenInfoUiaProvider` lets you interact with the displayed text.
`UiaTextRange` is specific ranges of text in the display and navigate the text.

Thankfully, we didn't do many changes here. I feel like some of it is hacked
together but now that we have a somewhat working system, making changes
shouldn't be too hard...I hope.

#### UiaTextRange
We don't have access to the window handle. We really only need it to draw the
bounding rects using WinUser's `ScreenToClient()` and `ClientToScreen()`. I
need to figure out how to get around this.

In the meantime, I made the window handle optional. And if we don't have
one....well, we need to figure that out. But other than that, we have a
`UiaTextRange`.

#### ScreenInfoUiaProvider
At some point, we need to hook up this automation provider to the
WindowUiaProvider. This should help with navigation of the UIA Tree and make
everything just look waaaay better. For now, let's just do the same approach
and make the pUiaParent optional.

This one's the one I'm not that proud of, but it works. We need the parent to
get a bounding rect of the terminal. While we figure out how to attach the
WindowUiaProvider, we should at the very least be able to get a bunch of info
from our xaml automation peer. So, I've added a _getBoundingRect optional
function. This is what's called when we don't have a WindowUiaProvider as our
parent.


## Validation Steps Performed
I've been using inspect.exe to see the UIA tree.
I was able to interact with the terminal mostly fine. A few known issues below.

Unfortunately, I tried running Narrator on this and it didn't seem to like it
(by that I mean WT crashed). Then again, I don't really know how to use
narrator other than "click on object" --> "listen voice". I feel like there's a
way to get the other interactions with narrator, but I'll be looking into more
of that soon. I bet if I fix the two issues below, Narrator will be happy.

## Miscellaneous Known Issues
- `GetSelection()` and `GetVisibleRanges()` crashes. I need to debug through
  these. I want to include them in this PR.

Fixes #1353.

When snapping to a lower DPI, this means the terminal will be smaller, with "padding" all around the actual app. 

Instead, when we get a new DPI, force us to update out UI layout for the new DPI.

Closes #2057

Fix a crash on restore down (#2149)
* Don't trigger a frame due to circling when in the middle of a resize operation

  This fixes #1795, and shined quite a bit of light on the whole conpty resize process.

* Move the Begin/End to ResizeScreenBuffer, to catch more cases.

Fixes crash when specifying invalid font (#2153)
* Stop the crash with fonts by trying a few fallback/backup fonts if we can't find what was selected.
* Create fallback pattern for finding a font. Resolve and pass the locale name. Retrieve the font name while retrieving the font object. Use retrieved data in the _GetProposedFont methods instead of re-resolving it.
* Add details to schema about fallback. Finish comment explaining fallback pattern to doc comment on method.

Add some ETL around profile, control and connection creation (#2125)
This commit adds some tracelogging (and telemetry) to answer the following questions:
* Do people use padding? If so, what is the common range of values?
* Are people turning off showTabsInTitlebar?
* How many different profiles are in use, and how do they break down between custom and default?
* Are people manually launching specific profiles, or using "default" fairly often?
* Are people using the Azure Cloud Shell connection?
* Are people leveraging the feature added in #2108 (autogenerating GUIDs)?

Accessibility: Set-up UIA Tree (#1691)
**The Basics of Accessibility**
- [What is a User Interaction Automation (UIA) Tree?](https://docs.microsoft.com/en-us/dotnet/framework/ui-automation/ui-automation-tree-overview)
- Other projects (i.e.: Narrator) can take advantage of this UIA tree and are used to present information within it.
- Some things like XAML already have a UIA Tree. So some UIA tree navigation and features are already there. It's just a matter of getting them hooked up and looking right.

**Accessibility in our Project**
There's a few important classes...
regarding Accessibility...
- **WindowUiaProvider**: This sets up the UIA tree for a window. So this is the top-level for the UIA tree.
- **ScreenInfoUiaProvider**: This sets up the UIA tree for a terminal buffer.
- **UiaTextRange**: This is essential to interacting with the UIA tree for the terminal buffer. Actually gets portions of the buffer and presents them.

regarding the Windows Terminal window...
- **BaseWindow**: The foundation to a window. Deals with HWNDs and that kind of stuff.
- **IslandWindow**: This extends `BaseWindow` and is actually what holds our Windows Terminal
- **NonClientIslandWindow**: An extension of the `IslandWindow`

regarding ConHost...
- **IConsoleWindow**: This is an interface for the console window.
- **Window**: This is the actual window for ConHost. Extends `IConsoleWindow`

- `IConsoleWindow` changes:
  - move into `Microsoft::Console::Types` (a shared space)
  - Have `IslandWindow` extend it
- `WindowUiaProvider` changes:
  - move into `Microsoft::Console::Types` (a shared space)
- Hook up `WindowUiaProvider` to IslandWindow (yay! we now have a tree)

### Changes to the WindowUiaProvider
As mentioned earlier, the WindowUiaProvider is the top-level UIA provider for our projects. To reuse as much code as possible, I created `Microsoft::Console::Types::WindowUiaProviderBase`. Any existing functions that reference a `ScreenInfoUiaProvider` were virtual-ized.

In each project, a `WindowUiaProvider : WindowUiaProviderBase` was created to define those virtual functions. Note that that will be the main difference between ConHost and Windows Terminal moving forward: how many TextBuffers are on the screen.

So, ConHost should be the same as before, with only one `ScreenInfoUiaProvider`, whereas Windows Terminal needs to (1) update which one is on the screen and (2) may have multiple on the screen.

🚨 Windows Terminal doesn't have the `ScreenInfoUiaProvider` hooked up yet. We'll have all the XAML elements in the UIA tree. But, since `TermControl` is a custom XAML Control, I need to hook up the `ScreenInfoUiaProvider` to it. This work will be done in a new PR and resolve GitHub Issue #1352.


### Moved to `Microsoft::Console::Types`
These files got moved to a shared area so that they can be used by both ConHost and Windows Terminal.
This means that any references to the `ServiceLocator` had to be removed.

- `IConsoleWindow`
  - Windows Terminal: `IslandWindow : IConsoleWindow`
- `ScreenInfoUiaProvider`
  - all references to `ServiceLocator` and `SCREEN_INFORMATION` were removed. `IRenderData` was used to accomplish this. Refer to next section for more details.
- `UiaTextRange`
  - all references to `ServiceLocator` and `SCREEN_INFORMATION` were removed. `IRenderData` was used to accomplish this. Refer to next section for more details.
  - since most of the functions were `static`, that means that an `IRenderData` had to be added into most of them.


### Changes to IRenderData
Since `IRenderData` is now being used to abstract out `ServiceLocator` and `SCREEN_INFORMATION`, I had to add a few functions here:
- `bool IsAreaSelected()`
- `void ClearSelection()`
- `void SelectNewRegion(...)`
- `HRESULT SearchForText(...)`

`SearchForText()` is a problem here. The overall new design is great! But Windows Terminal doesn't have a way to search for text in the buffer yet, whereas ConHost does. So I'm punting on this issue for now. It looks nasty, but just look at all the other pretty things here. :)
