Slomo CLI: timeline — Chronological Event Feed and Tail

slomo timeline prints every event in a session in chronological order. Use it for a quick read-through of what happened, or pipe it into other tools for further processing.

slomo timeline [REF] [OPTIONS]

REF

string

Session id (prefix ok), issue id, or empty for the latest session.

Option	Effect
`--follow`, `-f`	Live-tail a running session — new events print as they are written
`--errors`	Only warnings and errors

$ slomo timeline
04:52.130  function.enter   checkout(db=…, sku='gadget')
04:52.133  sql.query        SELECT sku, qty FROM inventory WHERE sku = ?
04:52.133  sql.result       0 rows, 9µs
04:52.134  function.exception  TypeError: 'NoneType' object is not subscriptable

Live-tailing

--follow watches the newest session’s timeline.jsonl and streams events as your app writes them — run your app in one terminal, the tail in another:

slomo timeline --follow            # everything, as it happens
slomo timeline --follow --errors   # quiet until something goes wrong

Because the writer batches every 0.5 s, events appear with at most that much delay.
