Over five months, Martin Jambon enhanced the semgrep/semgrep-interfaces repository by delivering six features focused on interface consistency, configuration flexibility, and deterministic output. He standardized module naming, introduced new input types for broader scanning workflows, and simplified targeting configuration by removing redundant fields while ensuring backward compatibility. Martin added support for custom ignore filenames and implemented deterministic sorting of results using OCaml and Protocol Buffers, improving CI reliability and maintainability. He also extended the type system with path-aware types to enable precise rule filtering. His work demonstrated depth in API design, schema evolution, and robust configuration management across multiple languages.
July 2025: Delivered a path-aware enhancement to Semgrep interfaces by introducing ppath and fppath types to support path-based rule matching in semgrep-interfaces. This enables include/exclude filtering using project-root relative paths and maintains backward compatibility with older CLI versions. A key commit (9e30c826207fd24b5a0edc0c59d7563351462ccb) ensures ppaths are tracked after target discovery to enable effective rule filtering (#375). No major bugs fixed this month in this repo. Impact: reduces unnecessary rule evaluations, improves filtering precision for large repos, and strengthens traceability and maintainability of the interface layer. Technologies/skills demonstrated: interface design, type-system extension, path handling, and change management with traceable commits.

June 2025 monthly summary for semgrep/semgrep-interfaces focusing on feature delivery that improves result determinism and pipeline reliability.
April 2025 (2025-04) — Key feature delivered in the semgrep-interfaces module: introduced a new configuration option semgrepignore_filename within targeting_conf to allow users to specify a custom filename for Semgrep ignore rules, while preserving backward compatibility with older CLI versions. This change enhances configurability for CI pipelines and simplifies onboarding for teams with bespoke rule files. The work is tracked under commit e9d7e14e52d8700ce3e40260812eb82412250d10 (Add semgrepignore_filename option) and is associated with PR #372. No major bugs were introduced or fixed this month in this scope; the focus was on feature delivery and stability. Overall, this release improves user flexibility, reduces configuration friction in diverse environments, and contributes to the maintainability of the semgrep-interfaces repository by cleanly extending the targeting_conf schema.
