SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Designing a Datalog DSL and compiler pipeline that targets SQL backends for code metadata analysis.

Core Features & Use Cases

  • Embeds built-in relations over a SQL schema (e.g., file, match, link, repo) and a modular extraction pipeline.
  • Supports pattern embedding for regex, AST, and file glob patterns via a readable design, incremental materialization, and a robust compiler pipeline.
  • Enables a SQLite-backed backend with a Souffle-like rule language and a clear translation to SQL.

Quick Start

Define a tiny schema, write a few Datalog rules, and compile them to SQL against a SQLite-backed test database.

FAQPage Schema
How do I compile Datalog rules to SQL for static code analysis?

To compile Datalog rules to SQL for static analysis, use a compiler pipeline that parses rules, resolves built-ins, type checks, stratifies, and emits SQL. This allows querying code metadata via a SQLite backend.

What is the best way to embed regex and AST patterns in a Datalog DSL?

Embedding regex, AST, and file glob patterns in a Datalog DSL involves using built-in relations like match and file. These built-ins integrate foreign patterns directly into rules for querying source code metadata.

Can I use a Souffle-like rule language with a SQLite backend?

Yes, you can use a Souffle-like rule language with a SQLite backend by designing a DSL that translates Datalog rules into SQL. This setup supports incremental materialization using INSERT OR IGNORE strategies.

How does incremental evaluation work when compiling Datalog to SQL?

Incremental evaluation in a Datalog to SQL compiler works by using an INSERT OR IGNORE strategy during materialization. This efficiently updates derived relations without recomputing the entire dataset.

What built-in relations are needed for analyzing code metadata with Datalog?

Analyzing code metadata with Datalog requires built-in relations such as file, match, link, and repo. These relations map to a SQL schema and support a modular extraction pipeline for source code patterns.
