Types

type ClipboardHistory 

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

ClipboardHistory is a domain service that manages clipboard history. It maintains a FIFO list of clipboard entries with configurable size and age limits.

func NewClipboardHistory 

func NewClipboardHistory(maxSize int, maxAge time.Duration) *ClipboardHistory

NewClipboardHistory creates a new clipboard history service. maxSize sets the maximum number of entries (0 = unlimited). maxAge sets the maximum age of entries (0 = no expiration).

func (*ClipboardHistory) Add 

func (h *ClipboardHistory) Add(content []byte, mimeType value.MIMEType) error

Add adds a new entry to the history. If maxSize is exceeded, the oldest entry is removed (FIFO). Returns the created entry or an error.

func (*ClipboardHistory) Clear 

func (h *ClipboardHistory) Clear()

Clear removes all entries from the history.

func (*ClipboardHistory) Contains 

func (h *ClipboardHistory) Contains(id string) bool

Contains checks if an entry with the given ID exists.

func (*ClipboardHistory) Get 

func (h *ClipboardHistory) Get(id string) (*model.HistoryEntry, error)

Get returns the entry with the given ID. Returns an error if the entry is not found.

func (*ClipboardHistory) GetAll 

func (h *ClipboardHistory) GetAll() []*model.HistoryEntry

GetAll returns all entries sorted by timestamp (newest first).

func (*ClipboardHistory) GetByMIMEType 

func (h *ClipboardHistory) GetByMIMEType(mimeType value.MIMEType) []*model.HistoryEntry

GetByMIMEType returns all entries matching the given MIME type. Results are sorted by timestamp (newest first).

func (*ClipboardHistory) GetRecent 

func (h *ClipboardHistory) GetRecent(count int) []*model.HistoryEntry

GetRecent returns the N most recent entries. If count is 0 or negative, returns all entries. If count exceeds available entries, returns all entries.

func (*ClipboardHistory) IsEmpty 

func (h *ClipboardHistory) IsEmpty() bool

IsEmpty returns true if there are no entries in the history.

func (*ClipboardHistory) MaxAge 

func (h *ClipboardHistory) MaxAge() time.Duration

MaxAge returns the maximum age of entries. Returns 0 if no expiration.

func (*ClipboardHistory) MaxSize 

func (h *ClipboardHistory) MaxSize() int

MaxSize returns the maximum number of entries allowed. Returns 0 if unlimited.

func (*ClipboardHistory) RemoveExpired 

func (h *ClipboardHistory) RemoveExpired() int

RemoveExpired removes all entries older than maxAge. If maxAge is 0 or negative, no entries are removed. Returns the number of entries removed.

func (*ClipboardHistory) SetMaxAge 

func (h *ClipboardHistory) SetMaxAge(maxAge time.Duration)

SetMaxAge updates the maximum age of entries. Does not automatically remove expired entries - call RemoveExpired() to clean up.

func (*ClipboardHistory) SetMaxSize 

func (h *ClipboardHistory) SetMaxSize(maxSize int)

SetMaxSize updates the maximum number of entries. If the new size is smaller than the current size, oldest entries are removed.

func (*ClipboardHistory) Size 

func (h *ClipboardHistory) Size() int

Size returns the number of entries in the history.

func (*ClipboardHistory) TotalSize 

func (h *ClipboardHistory) TotalSize() int

TotalSize returns the total memory usage of all entries in bytes.

type ClipboardService 

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

ClipboardService provides domain logic for clipboard operations.

func NewClipboardService 

func NewClipboardService(providers []Provider) (*ClipboardService, error)

NewClipboardService creates a new clipboard service with a prioritized list of providers.

func (*ClipboardService) GetAvailableProviderName 

func (s *ClipboardService) GetAvailableProviderName() string

GetAvailableProviderName returns the name of the first available provider.

func (*ClipboardService) IsAvailable 

func (s *ClipboardService) IsAvailable() bool

IsAvailable returns true if any provider is available.

func (*ClipboardService) Read 

func (s *ClipboardService) Read() (*model.ClipboardContent, error)

Read reads content from the first available provider.

func (*ClipboardService) ReadText 

func (s *ClipboardService) ReadText() (string, error)

ReadText reads text content from the clipboard.

func (*ClipboardService) Write 

func (s *ClipboardService) Write(content *model.ClipboardContent) error

Write writes content using the first available provider.

func (*ClipboardService) WriteText 

func (s *ClipboardService) WriteText(text string) error

WriteText writes text content to the clipboard.

type ImageCodec 

type ImageCodec struct{}

ImageCodec provides image encoding and decoding functionality. It's a domain service that handles image format conversions.

func NewImageCodec 

func NewImageCodec() *ImageCodec

NewImageCodec creates a new ImageCodec instance.

func (*ImageCodec) ConvertFormat 

func (c *ImageCodec) ConvertFormat(data []byte, targetFormat value.MIMEType) ([]byte, error)

ConvertFormat converts an image from one format to another.

func (*ImageCodec) Decode 

func (c *ImageCodec) Decode(data []byte) (image.Image, value.MIMEType, error)

Decode decodes image data from any supported format (PNG, JPEG, GIF, BMP). Returns the decoded image and the detected format.

func (*ImageCodec) DecodeGIF 

func (c *ImageCodec) DecodeGIF(data []byte) (image.Image, error)

DecodeGIF decodes GIF image data.

func (*ImageCodec) DecodeJPEG 

func (c *ImageCodec) DecodeJPEG(data []byte) (image.Image, error)

DecodeJPEG decodes JPEG image data.

func (*ImageCodec) DecodePNG 

func (c *ImageCodec) DecodePNG(data []byte) (image.Image, error)

DecodePNG decodes PNG image data.

func (*ImageCodec) DetectFormat 

func (c *ImageCodec) DetectFormat(data []byte) (value.MIMEType, error)

DetectFormat detects the image format from the data bytes. It uses magic bytes to identify the format.

func (*ImageCodec) EncodeGIF 

func (c *ImageCodec) EncodeGIF(img image.Image) ([]byte, error)

EncodeGIF encodes image data to GIF format.

func (*ImageCodec) EncodeJPEG 

func (c *ImageCodec) EncodeJPEG(img image.Image, quality int) ([]byte, error)

EncodeJPEG encodes image data to JPEG format with the specified quality (1-100). Default quality is 90 if quality <= 0 or quality > 100.

func (*ImageCodec) EncodePNG 

func (c *ImageCodec) EncodePNG(img image.Image) ([]byte, error)

EncodePNG encodes image data to PNG format. The input imageData should be raw pixel data or an already decoded image.

type Provider 

type Provider interface {
	// Read reads content from the clipboard
	Read() (*model.ClipboardContent, error)

	// Write writes content to the clipboard
	Write(content *model.ClipboardContent) error

	// IsAvailable returns true if the clipboard provider is available
	IsAvailable() bool

	// Name returns the name of the provider (e.g., "OSC52", "Windows Native")
