[tools] Add sharpie. Fixes #23962. #24622

rolfbjarne · 2026-02-04T11:39:25Z

Open-source the Objective-Sharpie tool.

Port the old closed-source version of Objective-Sharpie to modern .NET, and have it use ClangSharp for its clang integration.
This is a simplified port, any features that were not frequently used have been dropped. In particular, only two features remain:
- Binding an entire OS SDK (which we use for our own bindings).
Binding a .framework (to bind third-party bindings).
The new sharpie will be distributed as a .NET command-line tool.

Open-source the Objective-Sharpie tool. * Port the old closed-source version of Objective-Sharpie to modern .NET, and have it use ClangSharp for its clang integration. * This is a simplified port, any features that were not frequently used have been dropped.
