What the title says. 😄
Rather than relying on the potentially overloaded `!=` or `==` operators
when checking for null, now we'll use the `is` expression (possibly
combined with the `not` operator) to ensure correct checking. Probably
overkill for many of these classes, but decided to err on the side of
consistency. Would matter more on classes that may be inherited or
extended.
Using `is` and `is not` will provide us a guarantee that no
user-overloaded equality operators (`==`/`!=`) is invoked when a
`expression is null` is evaluated.
In code form, changed all instances of:
```c#
something != null
something == null
```
to:
```c#
something is not null
something is null
```
The one exception was checking null on a `KeyChord`. `KeyChord` is a
struct which is never null so VS will raise an error when trying this
versus just providing a warning when using `keyChord != null`. In
reality, we shouldn't do this check because it can't ever be null. In
the case of a `KeyChord` it **would** be a `KeyChord` equivalent to:
```c#
KeyChord keyChord = new ()
{
Modifiers = 0,
Vkey = 0,
ScanCode = 0
};
```
Regressed in one of the #40113 prs.
The Core.VM.PageViewModelFactory didn't actually know how to make a
ContentPage, because Core can't handle a FormContent.
But really, the CommandSettingsViewModel shouldn't have ever been in the
.Core namespace, nor should it have used the ContentPageViewModel.
To prevent future mistakes like this,
* I got rid of `Core.ViewModels/PageViewModelFactory`, cause we didn't
need it.
* I made `ContentPageViewModel` abstract, to prevent you from trying to
instantiate it
Closes#40778
_targets #40504_
Major refactoring for #40113
This moves a large swath of the codebase to a `.Core` project. "Core"
doesn't have any explicit dependencies on "extensions", settings or the
current `MainListPage`. It's just a filterable list of stuff. This
should let us make this component a bit more reusable.
This is half of a PR. As I did this, I noticed a particular bit of code
for TopLevelVViewModels and CommandPaletteHost that was _very rough_.
Solving it in this PR would make "move everything to a new project" much
harder to review. So I'm submitting two PRs simultaneously, so we can
see the changes separately, then merge together.
This PR stops us from synchronously initializing the settings page for every extension (including built-in's) on startup. That incurs a small penalty that really adds up the more extensions a user has.
Instead, we'll now only initialize the `CommandSettings` object when we first actually need it.
From a relatively unscientific test, this saves approximately 10% on the initialization of builtin commands, and for my setup, it trims about 28% off extension initialization (across all built-in's / extensions):
branch | Built-in load (ms) | Extension load (ms) | %Δ builtin | %Δ extensions |
-- | -- | -- | -- | -- |
main | 1455 | 6867.6 | | |
this PR | 1309.2 | 4919 | -10.02% | -28.37%
Closes#38321
Windows Command Palette ("CmdPal") is the next iteration of PowerToys Run. With extensibility at its core, the Command Palette is your one-stop launcher to start _anything_.
By default, CmdPal is bound to <kbd>Win+Alt+Space</kbd>.


----
This brings the current preview version of CmdPal into the upstream PowerToys repo. There are still lots of bugs to work out, but it's reached the state we're ready to start sharing it with the world. From here, we can further collaborate with the community on the features that are important, and ensuring that we've got a most robust API to enable developers to build whatever extensions they want.
Most of the built-in PT Run modules have already been ported to CmdPal's extension API. Those include:
* Installed apps
* Shell commands
* File search (powered by the indexer)
* Windows Registry search
* Web search
* Windows Terminal Profiles
* Windows Services
* Windows settings
There are a couple new extensions built-in
* You can now search for packages on `winget` and install them right from the palette. This also powers searching for extensions for the palette
* The calculator has an entirely new implementation. This is currently less feature complete than the original PT Run one - we're looking forward to updating it to be more complete for future ingestion in Windows
* "Bookmarks" allow you to save shortcuts to files, folders, and webpages as top-level commands in the palette.
We've got a bunch of other samples too, in this repo and elsewhere
### PowerToys specific notes
CmdPal will eventually graduate out of PowerToys to live as its own application, which is why it's implemented just a little differently than most other modules. Enabling CmdPal will install its `msix` package.
The CI was minorly changed to support CmdPal version numbers independent of PowerToys itself. It doesn't make sense for us to start CmdPal at v0.90, and in the future, we want to be able to rev CmdPal independently of PT itself.
Closes#3200, closes#3600, closes#7770, closes#34273, closes#36471, closes#20976, closes#14495

TODOs et al
**Blocking:**
- [ ] Images and descriptions in Settings and OOBE need to be properly defined, as mentioned before
- [ ] Niels is on it
- [x] Doesn't start properly from PowerToys unless the fix PR is merged.
- https://github.com/zadjii-msft/PowerToys/pull/556 merged
- [x] I seem to lose focus a lot when I press on some limits, like between the search bar and the results.
- This is https://github.com/zadjii-msft/PowerToys/issues/427
- [x] Turned off an extension like Calculator and it was still working.
- Need to get rid of that toggle, it doesn't do anything currently
- [x] `ListViewModel.<FetchItems>` crash
- Pretty confident that was fixed in https://github.com/zadjii-msft/PowerToys/pull/553
**Not blocking / improvements:**
- Show the shortcut through settings, as mentioned before, or create a button that would open CmdPalette settings.
- When PowerToys starts, CmdPalette is always shown if enabled. That's weird when just starting PowerToys/ logging in to the computer with PowerToys auto-start activated. I think this should at least be a setting.
- Needing to double press a result for it to do the default action seems quirky. If one is already selected, I think just pressing should be enough for it to do the action.
- This is currently a setting, though we're thinking of changing the setting even more: https://github.com/zadjii-msft/PowerToys/issues/392
- There's no URI extension. Was surprised when typing a URL that it only proposed a web search.
- [x] There's no System commands extension. Was expecting to be able to quickly restart the computer by typing restart but it wasn't there.
- This is in PR https://github.com/zadjii-msft/PowerToys/pull/452
