Syft is a production-grade CLI tool and Go library for generating Software Bills of Materials (SBOMs) from container images, filesystems, directories, and OCI artifacts. It detects and catalogs packages across 40+ ecosystems (Alpine, Debian, RPM, Python, Java, Go, Ruby, Rust, JavaScript, .NET, etc.) by parsing lockfiles, package databases, binary metadata, and source manifests. The tool outputs SBOMs in multiple formats including CycloneDX (JSON/XML), SPDX (JSON/tag-value), Syft JSON, and GitHub Dependency Snapshots, with version-aware encoding and decoding. Architecturally, Syft uses a modular cataloger system where each ecosystem implements a `generic.Cataloger` with parser functions registered by file globs or MIME types. A task-based pipeline orchestrates file indexing, package cataloging, dependency resolution, and relationship linking. The system supports both library integration via `syft.CreateSBOM()` and a CLI with cobra commands (`scan`, `attest`, `convert`, `cataloger`). A bubbletea-based TUI provides real-time progress feedback during image pulls and cataloging. External dependencies include `stereoscope` for container image access, `cosign` for attestation signing, and `go-partybus` for event-driven UI. Key entry points include `cmd/syft/main.go` (CLI), `syft/create_sbom.go` (library API), `syft/get_source.go` (source resolution), and the format encoders/decoders in `syft/format/`. The codebase demonstrates strong engineering practices: extensive test coverage (unit, integration, snapshot), CI/CD with GitHub Actions, auto-generated JSON schemas, and drift-check scripts for capabilities and schema. Notable reusable components include the generic cataloger framework, the dependency resolver, and the file resolver abstraction.
