[CmdPal][AOT] Using ExprTk to make the Cal extension AOT-compatible (#39972)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? --> ## Summary of the Pull Request This PR replaces the original Mages-based expression evaluation engine with a WinRT-wrapped version of Exprtk in the CmdPalCalculator module. ### Key Changes **Expression Engine:** - All expression parsing and evaluation now use Exprtk (via a WinRT wrapper) instead of Mages. **Base Conversion Handling:** - Since Exprtk does not support non-decimal (binary, octal, hexadecimal) input natively, added logic to convert all such inputs to decimal before evaluation. **Code Structure:** - The overall logic and API surface remain unchanged except for the engine and base conversion handling. - All previous Mages references and dependencies have been removed. <!-- Please review the items on the PR checklist before submitting--> ## PR Checklist - [ ] **Closes:** #xxx - [ ] **Communication:** I've discussed this with core contributors already. If work hasn't been agreed, this work might be rejected - [ ] **Tests:** Added/updated and all pass - [ ] **Localization:** All end user facing strings can be localized - [ ] **Dev docs:** Added/updated - [ ] **New binaries:** Added on the required places - [ ] [JSON for signing](https://github.com/microsoft/PowerToys/blob/main/.pipelines/ESRPSigning_core.json) for new binaries - [ ] [WXS for installer](https://github.com/microsoft/PowerToys/blob/main/installer/PowerToysSetup/Product.wxs) for new binaries and localization folder - [ ] [YML for CI pipeline](https://github.com/microsoft/PowerToys/blob/main/.pipelines/ci/templates/build-powertoys-steps.yml) for new test projects - [ ] [YML for signed pipeline](https://github.com/microsoft/PowerToys/blob/main/.pipelines/release.yml) - [ ] **Documentation updated:** If checked, please file a pull request on [our docs repo](https://github.com/MicrosoftDocs/windows-uwp/tree/docs/hub/powertoys) and link it here: #xxx <!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well --> ## Validation Steps Performed

# C++/WinRT CalculatorEngine Project Overview
|
||||
|
||||
This project wraps the exprtk expression parsing library with a C++/WinRT component,
|
||||
making advanced mathematical evaluation capabilities available to Windows applications.
|
||||
It is designed specifically to provide calculation support for the CmdPal calculator extension.
|
||||
|
||||
## Using exprtk
|
||||
|
||||
This project uses [exprtk](https://github.com/ArashPartow/exprtk) as the
|
||||
expression parsing and evaluation engine.
|
||||
|
||||
How to use exprtk in this project:
|
||||
- The exprtk header file (`exprtk.hpp`) is included in the project source.
|
||||
- You can use exprtk to parse and evaluate mathematical expressions in your
|
||||
C++ code. For example:
|
||||
|
||||
```cpp
|
||||
#include "exprtk.hpp"
|
||||
exprtk::expression<double> expression;
|
||||
exprtk::parser<double> parser;
|
||||
std::string formula = "3 + 4 * 2";
|
||||
parser.compile(formula, expression);
|
||||
double result = expression.value();
|
||||
```
|
||||
|
||||
How to update exprtk:
|
||||
1. Download the latest `exprtk.hpp` from the [official repository](https://github.com/ArashPartow/exprtk).
|
||||
2. Replace the existing `exprtk.hpp` file in the project with the new version.
|
||||
3. Rebuild the project to ensure compatibility and take advantage of any updates.
