Какие-то энтузиасты сделали SQL-обёртку над гитом. Можно сделать SELECT по коммитам или, например, веткам, отфильтровав по автору и сгруппировав еще по чему-нибудь.

SELECT DISTINCT title AS tt message FROM commits
SELECT name, COUNT(name) AS commit_num FROM commits GROUP BY name ORDER BY commit_num DESC LIMIT 10
SELECT commit_count FROM branches WHERE commit_count BETWEEN 0 .. 10

SELECT * FROM refs WHERE type = "branch"
SELECT * FROM refs ORDER BY type

SELECT * FROM commits
SELECT name, email FROM commits
SELECT name, email FROM commits ORDER BY name DESC, email ASC
SELECT name, email FROM commits WHERE name LIKE "%gmail%" ORDER BY name
SELECT * FROM commits WHERE LOWER(name) = "amrdeveloper"
SELECT name FROM commits GROUP By name
SELECT name FROM commits GROUP By name having name = "AmrDeveloper"

SELECT * FROM branches
SELECT * FROM branches WHERE is_head = true
SELECT name, LEN(name) FROM branches

SELECT * FROM tags
SELECT * FROM tags OFFSET 1 LIMIT 1
