GQL - Git Query Language
GQL is a query language with a syntax very similar to SQL with a tiny engine to perform queries on .git files instead of database files. The engine executes the query on the fly without the need to create database files or convert .git files into any other format.

### Samples
Note that all Keywords in GQL are case-insensitive, similar to SQL.
```sql
SELECT 1
SELECT 1 + 2
SELECT LEN("Git Query Language")
SELECT "One" IN ("One", "Two", "Three")
SELECT "Git Query Language" LIKE "%Query%"
SET @arr = [1, 2, 3];
SELECT [[1, 2, 3], [4, 5, 6], [7, 8, 9]];
SELECT @arr[1], @arr[2], @arr[3], ARRAY_LENGTH(@arr);
SELECT @arr[1:2], @arr[2:], @arr[:2];
SELECT DISTINCT title AS tt FROM commits
SELECT author_name, COUNT(author_name) AS commit_num FROM commits GROUP BY author_name, author_email 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 author_name, author_email FROM commits
SELECT author_name, author_email FROM commits ORDER BY author_name DESC, author_email ASC
SELECT author_name, author_email FROM commits WHERE name LIKE "%gmail%" ORDER BY author_name
SELECT * FROM commits WHERE LOWER(name) = "amrdeveloper"
SELECT author_name FROM commits GROUP By author_name
SELECT author_name FROM commits GROUP By author_name having author_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
```
