TtyMode

TtyMode = "raw" | "raw-optional" | "line"

Defined in: packages/core/src/kernel/types.ts:2130

Terminal requirement policy for WASM/WASI process spawn.

Remarks

Controls what the WASM/WASI exec layer does when a program expects raw-mode TTY access:

• 'raw': require a terminal; reject with ENOTTY when absent (e.g. when stdin is a pipe)
• 'raw-optional': prefer a terminal but degrade to line mode when absent
• 'line' (default): never engage raw mode, even when a terminal is attached
