dlog

dlog is a small CLI for daily work log.

Install

go install github.com/okaryo/dlog@latest

Usage

dlog "task progress update"
dlog amend "corrected task progress update"
dlog
dlog log
dlog log --date 2026-04-12
dlog md
dlog md --date 2026-04-12

Behavior

• dlog "text" appends a log entry for today with the current local timestamp.
• dlog amend "text" replaces today's most recent log entry while keeping its original timestamp.
• dlog and dlog log show today's logs in reverse chronological order.
• dlog log --date YYYY-MM-DD shows logs for the specified date.
• dlog md prints today's logs in Markdown order from oldest to newest.
• dlog md --date YYYY-MM-DD prints logs for the specified date in Markdown order.
• Displayed times use the timezone recorded in each log entry, not the viewer's current local timezone.

Examples

Record logs for today:

$ dlog "task progress update"
$ dlog "api design"
$ dlog "bug fix"

Amend the most recent log entry:

$ dlog amend "bug fix (retry with test case)"

Show today's logs in reverse chronological order with dlog or dlog log:

$ dlog
2026-04-12

11:10 bug fix (retry with test case)
10:25 api design
10:03 task progress update

$ dlog log
2026-04-12

11:10 bug fix (retry with test case)
10:25 api design
10:03 task progress update

Show a specific date:

$ dlog log --date 2026-04-11
2026-04-11

18:45 previous day task

Output logs as Markdown in chronological order:

$ dlog md
# 2026-04-12
- 10:03 task progress update
- 10:25 api design
- 11:10 bug fix (retry with test case)

Output a specific date as Markdown:

$ dlog md --date 2026-04-11
# 2026-04-11
- 18:45 previous day task

Storage

• Logs are stored under ~/.dlog.
• Each day is stored as one JSON file named YYYY-MM-DD.json.
• Timestamps are saved in RFC3339 format with the local time zone.

Example:

{
  "date": "2026-04-12",
  "logs": [
    {
      "timestamp": "2026-04-12T10:03:21+09:00",
      "text": "task progress update"
    }
  ]
}
