Daily Commit Counts as a Terminal Graph w/ Emojis 🚀

Here's a use case of a project I recently made public. It's called gitqlite and lets users run SQL queries on git repositories.

Display a terminal chart of commit counts for a repo (facebook/react, here) by day, for the past N days (30 in this case):

cat query.sql | gitqlite --repo https://github.com/facebook/react
+------------+-----+-------+----------------------------
|    DAY     | DOW | COUNT |          COMMITS

The SQL in query.sql looks like:

WITH RECURSIVE
days(day) AS (
    SELECT strftime('%Y-%m-%d', DATETIME('now'))
    UNION ALL
    SELECT strftime('%Y-%m-%d', (SELECT DATETIME(day, '-1 day'))) FROM days
    LIMIT 30
)
SELECT
    days.day,
    substr('SunMonTueWedThuFriSat', 1 + 3*strftime('%w', days.day), 3) as dow,
    IFNULL(count, 0) AS count,
    CASE count IS NULL WHEN true THEN '' ELSE printf('%.' || (IFNULL(count, 0)) || 'c', '✅') END AS commits
FROM days LEFT JOIN (
    SELECT strftime('%Y-%m-%d', committer_when) AS day, count(*) AS count FROM commits GROUP BY day
) c ON c.day = days.day
