Design Principles¶

The CPG represents the code's ...¶

• Structure/Syntax
• Data Flows
• Execution Order/Control Flow
• Variable Usage
• Calls
• The Type System

The CPG should parse ...¶

• Incomplete code
• Code with missing toolchains
• With resilience to incorrect code
• Language heterogeneous projects

CPG-Library users should be able to ...¶

• Load projects and single files
• Visualize and analyze code
• Implement and register new Language Frontends
• Extends and modify existing components, e.g., passes
• Parse code incrementally

The CPG-Transformation should be ...¶

• Language independent: Allow for language independent and cross-language queries
• Information-rich: contain language-specific information in generalized structures
• Fast (enough).
  • Small Projects/Development projects should be analyzable in real-time, at most some seconds.
  • Large libraries should take no longer than a few hours.
  • About 5 to 10 times as long as the compilation process.
