Types

type Buffer added in v0.0.10 

type Buffer struct {
	text.Lines

	// Filename is the filename of the file that was last loaded or saved.
	// It is used when highlighting code.
	Filename core.Filename `json:"-" xml:"-"`

	// Autosave specifies whether the file should be automatically
	// saved after changes are made.
	Autosave bool

	// Info is the full information about the current file.
	Info fileinfo.FileInfo

	// LineColors are the colors to use for rendering circles
	// next to the line numbers of certain lines.

	// Complete is the functions and data for text completion.
	Complete *core.Complete `json:"-" xml:"-"`

}

Buffer is a buffer of text, which can be viewed by Editor(s). It holds the raw text lines (in original string and rune formats, and marked-up from syntax highlighting), and sends signals for making edits to the text and coordinating those edits across multiple views. Editors always only view a single buffer, so they directly call methods on the buffer to drive updates, which are then broadcast. It also has methods for loading and saving buffers to files. Unlike GUI widgets, its methods generally send events, without an explicit Event suffix. Internally, the buffer represents new lines using \n = LF, but saving and loading can deal with Windows/DOS CRLF format.

Editor is a widget for editing multiple lines of complicated text (as compared to core.TextField for a single line of simple text). The Editor is driven by a Buffer buffer which contains all the text, and manages all the edits, sending update events out to the editors.

Use NeedsRender to drive an render update for any change that does not change the line-level layout of the text. Use NeedsLayout whenever there are changes across lines that require re-layout of the text. This sets the Widget NeedsRender flag and triggers layout during that render.
