Types

type BufferSets

type BufferSets []*bufferSet

Buffers

func NewBufferSets

func NewBufferSets(paths []string) (bss *BufferSets, errs error)

Create te.Editor.Buffers from Files (command line arguments) Always one will be created

Create bufferSet and append to Buffers from path string array

From paths (command line argument) create te.Editor.Buffers Create one bufferSet, even if there is none.

func (*BufferSets) Append

func (bss *BufferSets) Append(buffSet *bufferSet)

func (*BufferSets) BufferSet

func (bss *BufferSets) BufferSet(ff *file.File) *bufferSet

Find BufferSet in BufferSetArray

func (*BufferSets) GetFileAndMeta

func (bss *BufferSets) GetFileAndMeta(filePath string) (*file.File, *Meta, error)

Find the buffer and meta for filePath from Buffers Create a new buffer otherwise Load into buffer if the file exists Register into Buffers Return buffer and meta

func (*BufferSets) GetIndexByBufferFile

func (bss *BufferSets) GetIndexByBufferFile(ff *file.File) int

Check if the specified *file.File exists in BufferSets If found, return its index If not found, return -1

func (*BufferSets) GetMeta

func (bss *BufferSets) GetMeta(ff *file.File) *Meta

Find a buffer from the bufferSetArray If found, return the meta from metas If metas does not exist, return a new meta If there exists an Editor, you could call "func (e *Editor) GetMeta() *meta {}"

func (*BufferSets) RemoveByBufferFile

func (bss *BufferSets) RemoveByBufferFile(ff *file.File) int

type Meta
