SemgrepScanner

SemgrepScanner(config: dict[str, Any] | None = None)

Pattern-based static analysis security scanner using Semgrep.

Scans code for security vulnerabilities, bugs, and anti-patterns using customizable pattern rules. Supports many languages including Python, JavaScript, Go, Java, and more.

Initialize Semgrep scanner.

Parameters:

Name	Type	Description	Default
config	dict[str, Any] | None	Scanner configuration options. If "config" is not specified, will auto-detect .provide/security/semgrep.yml if it exists.	None

Source code in provide/testkit/quality/security/semgrep_scanner.py
