Mitchell Hashimoto libghostty: add _get_multi to all _get APIs 4mo ago

libghostty: add _get_multi to all _get APIs Replace the ImageInfo and PlacementInfo sized structs and their associated .info enum variants with a new _get_multi pattern that batches multiple enum+pointer pairs into a single call. This avoids struct ABI concerns (field order, padding, alignment, GHOSTTY_INIT_SIZED) while preserving the single-call-crossing performance benefit for FFI and Cgo callers. Each _get_multi function takes an array of enum keys, an array of output pointers, and an optional out_written parameter that reports how many values were successfully written before any error. This applies uniformly to all _get APIs: terminal_get, cell_get, row_get, render_state_get, render_state_row_get, render_state_row_cells_get, kitty_graphics_image_get, and kitty_graphics_placement_get. The C example is updated to use compound-literal _get_multi calls, and tests cover both success and error paths for every new function.

example: add c-vt-kitty-graphics Demonstrates the sys interface for Kitty Graphics Protocol PNG support. The example installs a PNG decode callback via ghostty_sys_set, creates a terminal with image storage enabled, and sends an inline 1x1 PNG image through vt_write. Snippet markers are wired up to the sys.h doxygen docs.

Example: `ghostty-vt` Kitty Graphics Protocol#

This contains a simple example of how to use the system interface (ghostty_sys_set) to install a PNG decoder callback, then send a Kitty Graphics Protocol image via ghostty_terminal_vt_write.

This uses a build.zig and Zig to build the C program so that we can reuse a lot of our build logic and depend directly on our source tree, but Ghostty emits a standard C library that can be used with any C tooling.

Usage#

Run the program:

zig build run
