ClangQL - Clang AST Query Language

ClangQL is a tool that allow you to run SQL-like query on C/C++ Code instead of database files using the GitQL SDK.

Samples

Note that all Keywords in ClangQL are case-insensitive, similar to SQL.

SELECT 1
SELECT 1 + 2
SELECT LEN("Clang Query Language")
SELECT "One" IN ("One", "Two", "Three")
SELECT "Clang Query Language" LIKE "%Query%"

SELECT * FROM functions
SELECT COUNT(name) from functions WHERE return_type = "int"
SELECT DISTINCT name AS function_name FROM functions

SELECT * FROM globals
SELECT COUNT(name) from globals WHERE type = "int"
SELECT * FROM globals WHERE is_volatile
