pub fn parse_daemon_bool(value: &str) -> Option<bool>Expand description
The boolean grammar of shep.toml and the SHEP_* environment: 1,
0, true, false, and nothing else.
One function so the file/env layer and the --log-json flag cannot
drift. clap’s own BoolishValueParser additionally accepts
yes/no/y/n/on/off; using it would widen the grammar on the
flag side only.
Not a general boolean parser: exporting it only under this name keeps exactly one answer to what counts as true in shep’s daemon config.
