Functions

func ArtifactPurl 

func ArtifactPurl(scanner string, assetName string) string

func BeautifyPURL 

func BeautifyPURL(pURL string) (string, error)

function to make purl look more visually appealing

func ConvertToSemver 

func ConvertToSemver(originalVersion string) (string, error)

ConvertToSemver converts various version formats to semantic versioning format. It handles: - Epoch prefixes (e.g., "2:1.2.3" -> "1.2.3") - "v" prefixes (e.g., "v1.2.3" -> "1.2.3") - Pre-release identifiers with "-" (e.g., "1.2.3-rc1") - Build metadata with "+" (e.g., "1.2.3+build1") - Tilde versions "~" (e.g., "1.2.3~rc1" -> "1.2.3-rc1") - Missing version segments (e.g., "1.2" -> "1.2.0")

Returns an error if: - Version contains invalid characters (only 0-9 and . allowed in version part) - Version has more than 3 numeric segments
