kempnerpulse.present.controller

Keyboard command handling and the raw-terminal context manager.

CommandController owns the view state the dashboard reads (focused GPU, plot/job mode, fleet scroll offset, the :-command buffer) and parses raw stdin bytes — including CSI arrow/page escape sequences — into state changes. cbreak_stdin() puts the terminal into cbreak mode so single keystrokes are delivered without a newline; outside a TTY it is a no-op.

Functions

cbreak_stdin(enabled)

Put stdin into cbreak mode for single-keystroke input; no-op off-TTY.

Classes

CommandController

View-mode and input state shared between the input loop and the renderer.
