Verify if the StandardCalculatorViewModel::DisplayValue isn't an error message before removing group separators (including space character).
How changes were validated:
Tested in english and french
Tested with "Cannot divide by zero" and "Result is undefined"

Adjusted some of the values in .clang-format
Add clang-format-all.ps1
Fix path to .clang-format in Calculator.sln
How changes were validated:
Manual.
Fixes#202
This PR fixes code style for the project files.
The Problem
Different files in the project use different code style. That is not consistent and leads to harder maintenance of the project.
Description of the changes:
Have investigated and determined the most used code style across the given codebase
Have configured IDE and applied code style to all project files.
Have crafted clang-formatter config.
see https://clang.llvm.org/docs/ClangFormat.htmlhttps://clang.llvm.org/docs/ClangFormatStyleOptions.html
Some cases were fixed manually
How changes were validated:
manual/ad-hoc testing, automated testing
All tests pass as before because these are only code style changes.
Additional
Please review, and let me know if I have any mistake in the code style. In case of any mistake, I will change the configuration and re-apply it to the project.
Fixes#402 and #414
Divide by 4 the CPU usage of OverflowTextBlock when buttons are pressed very quickly.
Description of the changes:
Xaml-side:
OverflowTextBlock has some performance issues:
double scrollviewer: the listview was in a scrollviewer, while the control already containing one -> it breaks the virtualization of the listview and impacts on UI performance.
The listview used a StackPanel, this panel doesn't support virtualization of ListViewItems contrary to ItemsStackPanel
No ListView-specific features were used, an ItemsControl is more efficient and lighter.
refactor how we manage the visibility of the left/right buttons in OverflowTextBlock, the new version is more reactive and will not display the right arrow when not necessary (see GIF below).
remove the ItemContainerSelector ExpressionItemContainerStyle, not really used by OverflowTextBlock
remove UI glitches generated by ChangeView when users type fast (control partially hidden and scrolling issues, see the GIF below).
only modify the accessibility view when it's necessary
ViewModel-side:
stop fully refreshing ExpressionTokens in StandardCalculatorViewModel when a new command were sent, instead, use a IObservableVector to only send new tokens to the UI (in average only 1 or 2 UI items are refreshed while the full expression was refreshed before)
How changes were validated:
Manually
Fixed comments that were inconsistent with the style guidelines described in C++ core guidelines and the modern C++/WinRT language projections and removed trailing whitespace.
Inserted a space after the beginning of the comment so the text wasn't touching the // on all occurrences.
Removed all occurrences of trailing whitespace
Previously, the CalculatorManager was managed with a unique_ptr that was instantiated in the ViewModel's constructor and was never re-assigned. Objects with long lifetime and larger memory footprint should live in dynamic memory, but the ViewModel itself lives in dynamic memory so that goal is still satisfied by storing the CalculatorManager directly in the class. The change allows the compiler to write a more efficient memory footprint for the same data.
- Verified by testing basic app functionality and running unit tests locally.
Before this change, the pchs for CalcViewModel and Calculator project referenced project headers. If those project headers (or any of their dependencies) were to change, then the pch would be recompiled, slowing local build times.
By removing references to project headers, the pch will be compiled once and is resilient to changes in the project. Now that project headers are explicit about their dependencies, when there is a change to a project header only the translation units referencing the modified header will need to be rebuilt.
- Manually tested by ensuring Calculator project builds locally.
