Overview ¶

Package sourcemark stores a source node's custom feed mark as a normalized square PNG under the app data dir, content-addressed by hash. A node's config records the hash; a missing file falls back to the node's glyph. See ADR webhook-source-image-marks.

Functions ¶

func ValidHash ¶

func ValidHash(s string) bool

ValidHash reports whether s is lowercase hex of length HashLen — the shape Set produces. It also guards Get against path traversal.

Types ¶

type Store ¶

type Store struct {
	// contains filtered or unexported fields
}

Store keeps normalized mark PNGs under dir, one per content hash.

func NewStore ¶

func NewStore(dir string) *Store

NewStore returns a store rooted at dir. The directory is created on first write.

func (*Store) Get ¶

func (s *Store) Get(hash string) (data []byte, ok bool, err error)

Get returns the stored PNG for hash, or ok=false when none is stored. A malformed or missing hash reads as absent, not an error.

func (*Store) Set ¶

func (s *Store) Set(raw []byte) (string, error)

Set normalizes raw into a square PNG, writes it as <hash>.png, and returns the content hash a node's config records.
