Module stdin_helper 

Stdin reader with configurable timeout to prevent indefinite blocking. Stdin reader with timeout to prevent indefinite blocking when the upstream pipe is held open without sending data.

Used by remember body-from-stdin and edit body input to enforce a deadline (crate::constants::DEFAULT_STDIN_READ_TIMEOUT_SECS, override via XDG cli.stdin_timeout_secs). When the timeout fires, the spawned reader thread is leaked because std::io::stdin() cannot be cancelled from outside; this is acceptable in error scenarios because the process is about to exit anyway.

Two refusals happen before any read is attempted:

• --no-input (or XDG cli.no_input) makes the refusal DECLARATIVE — it holds even when a pipe is attached and would have supplied data;
• an interactive TTY makes it EMERGENT — there is no producer, so waiting for EOF would just burn the whole deadline.

Functions

install_no_input

Installs the resolved --no-input decision for the whole process.

no_input

Whether stdin reads are refused for this invocation.

read_stdin

Reads stdin to a String with the configured deadline.

read_stdin_with_timeout

Reads stdin to a String with a hard deadline.
