func HasSBOM ¶

func HasSBOM(fsys fs.FS) bool

HasSBOM reports whether the bundle filesystem contains an SBOM directory with at least one recognized SBOM file.

Types ¶

type Change ¶

type Change struct {
	Package  string     `json:"package"`
	Type     ChangeType `json:"type"`
	Field    string     `json:"field,omitempty"`
	OldValue string     `json:"oldValue,omitempty"`
	NewValue string     `json:"newValue,omitempty"`
}

Change represents a single SBOM package change.

type ChangeType ¶

type ChangeType string

ChangeType describes how an SBOM package changed.

const (
	PackageAdded    ChangeType = "added"
	PackageRemoved  ChangeType = "removed"
	PackageModified ChangeType = "modified"
)

type Document ¶

type Document struct {
	Format   string    `json:"format"` // "spdx" or "cyclonedx"
	Packages []Package `json:"packages"`
}

Document represents a parsed SBOM document, independent of format.

func ParseFromFS ¶

func ParseFromFS(fsys fs.FS) (*Document, error)

ParseFromFS detects and parses an SBOM file from the bundle filesystem. It looks for files matching *.spdx.json or *.cdx.json inside the sbom/ directory. Returns nil, nil if no SBOM is found.

type Package ¶

type Package struct {
	Name     string `json:"name"`
	Version  string `json:"version"`
	License  string `json:"license,omitempty"`
	Supplier string `json:"supplier,omitempty"`
}

Package represents a normalized software package extracted from an SBOM.

type Result ¶

type Result struct {
	OldFormat string   `json:"oldFormat,omitempty"`
	NewFormat string   `json:"newFormat,omitempty"`
	Changes   []Change `json:"changes"`
}

Result holds the SBOM diff output.

func Diff ¶

func Diff(old, new *Document) *Result

Diff compares two SBOM documents and returns changes. Packages are matched by name. Returns nil if both documents are nil.
