Render state already tracks the selected cell range for each viewport row, but C renderers could only get the full terminal selection. That required consumers to map global selection pins back into row-local spans themselves. Add row selection data to the render-state row API. Querying the new row data returns GHOSTTY_NO_VALUE for unselected rows and writes the inclusive start and end columns for selected rows. The render example now demonstrates setting a selection and reading the row-local range while iterating rows.
Examples
Standalone projects demonstrating the Ghostty library APIs.
The directories starting with c- use the C API and the directories
starting with zig- use the Zig API.
Every example can be built and run using zig build and zig build run
from within the respective example directory.
Even the C API examples use the Zig build system (not the language) to
build the project.
Running an Example
cd example/<dir>
zig build run
