To port Semgrep rules to multiple programming languages, provide an existing rule YAML and a list of target languages. The process generates independent directories per language, each containing the ported rule YAML and corresponding tests for isolated validation.

Translating Semgrep rules for a polyglot codebase is best handled by generating dedicated rule and test directories per target language. This extends rule coverage across multiple languages while preserving original logic and enabling independent iteration.

Yes, generating test files is handled automatically when porting Semgrep rule YAML. The process outputs directories named with the rule and target language, containing both the adapted rule YAML and the corresponding test files for immediate validation.

Yes, an existing Semgrep rule in YAML format or equivalent rule content is required before porting. This original rule and a list of target languages are the required inputs to generate the per-language directories for the ported rules.

Cross-language Semgrep rule porting handles independent validation by creating separate directories for each target language. Each directory contains the ported rule YAML and its corresponding tests, allowing you to validate and iterate on each language independently.

Porting Semgrep rules across polyglot codebases is limited by the construct similarity between the original and target languages. The process is most applicable when translating rules to languages with similar constructs, relying on an existing rule YAML to function properly.
