}

Fields

path: PathBuf

File to view.

range: Option<String>

Line range A:B (1-based, inclusive); also A: (to end), :B (from start), or A (one line).

pattern: Option<String>

Show only lines matching this pattern (substring->glob->regex promoted), with –context around each. Accepts file:PATH / text:VALUE; a multi-line pattern matches as a line-anchored literal block.

mode: Option<Mode>

Pin how the pattern is interpreted (promotion off): literal, glob, or regex.

context: usize

Lines of context shown around each –match hit.

limit: Option<usize>

Cap the number of lines emitted.

timeout: Option<f64>

Abort with exit 2 if the view exceeds SECS seconds (fractional allowed).

heartbeat: HeartbeatOpts

plain: bool

Suppress the line-number gutter in text output.

json: bool

Emit a structured JSON result instead of text.

json_pretty: bool

Like --json, but pretty-printed (indented).

explain: Option<Format>

Print agent usage docs (md or json) and exit.
