Ports ZIG/src/inspector (the Dear ImGui terminal inspector) as the
ghostty-inspector crate using dear-imgui-rs + dear-imgui-glow (imgui-rs
lacks a safe docking API): screen, modes, keyboard events, terminal IO
/ VT sequence log with filtering, cell inspector with picking, page
list, renderer and size/font info, with Ghostty's docking layout. The
crate denies unsafe except a single dock.rs module wrapping DockBuilder.
GTK: imgui_widget, inspector_widget and inspector_window classes with
their blueprints replace the former no-op; ctrl+shift+i toggles the
inspector window.
Core: activate/deactivate hooks, key event and mouse recording, and VT
stream recording in termio while an inspector is active, as in Zig;
overlay features reach the renderer through an InspectorHook on the
render state. The debug input replay hook gained inspector-screenshot/
click/scroll steps used to verify all tabs in the real app.
Deviations: font size scales with the display scale instead of Zig's
fixed 16*2; pop-out dock splits apply one frame later; DCS/APC
descriptions are approximated.
Test Plan:
- cargo test -p ghostty-inspector (15 incl. headless full-UI draw)
- cargo test -p ghostty-core --test e2e_inspector (4)
