%description
weggli is a fast and robust semantic search tool for C and C++ codebases. It is
designed to help security researchers identify interesting functionality in
large codebases.

weggli performs pattern matching on Abstract Syntax Trees based on user
provided queries. Its query language resembles C and C++ code, making it easy
to turn interesting code patterns into queries.

weggli is inspired by great tools like Semgrep, Coccinelle, joern and CodeQL,
but makes some different design decisions:

C++ support: weggli has first class support for modern C++ constructs, such as
lambda expressions, range-based for loops and constexprs.

Minimal setup: weggli should work out-of-the box against most software you will
encounter. weggli does not require the ability to build the software and can
work with incomplete sources or missing dependencies.

Interactive: weggli is designed for interactive usage and fast query
performance. Most of the time, a weggli query will be faster than a grep
search. The goal is to enable an interactive workflow where quick switching
between code review and query creation/improvement is possible.

Greedy: weggli's pattern matching is designed to find as many (useful) matches
as possible for a specific query. While this increases the risk of false
positives it simplifies query creation. For example, the query $x = 10; will
match both assignment expressions (foo = 10;) and declarations (int bar = 10;).
