Backfilling a Missed Day

Every command that is tied to a day accepts --date MM-DD-YYYY, so a day you missed can be reconstructed later. WORK.md is always the scratch pad the daily log is built from; the date flags only decide which day is fetched and which file the log is written to.

Backfilling yesterday

Yesterday is the day people miss most, so it has its own flag. --yesterday picks the same date --date would, without you having to work it out:

swelog reset
# write yesterday's notes into WORK.md
swelog fetch github --yesterday
swelog fetch google-calendar --yesterday
swelog fetch linear --yesterday
swelog log --yesterday

For any other day, use --date as below.

Backfill flags

Command	Backfill flag	Shortcut
swelog log	--date MM-DD-YYYY	--yesterday
swelog fetch github	--date MM-DD-YYYY	--yesterday
swelog fetch google-calendar	--date MM-DD-YYYY	--yesterday
swelog fetch linear	--date MM-DD-YYYY	--yesterday
swelog summarize day	--date MM-DD-YYYY	--yesterday
swelog summarize week	--week-of MM-DD-YYYY	--last-week

--last-week goes back one week from the Monday swelog summarize week would pick on its own, which is always the Monday of the week containing today. Run it on a Monday and you get the week that just ended, which is what you want when you left on Friday without filing the week.
