Method ReplaceText

texteditor/buffer.go:789–801

ReplaceText does DeleteText for given region, and then InsertText at given position (typically same as delSt but not necessarily), optionally emitting a signal after the insert. if matchCase is true, then the lexer.MatchCase function is called to match the case (upper / lower) of the new inserted te

(delSt, delEd, insPos lexer.Pos, insTxt string, signal, matchCase bool)

// case (upper / lower) of the new inserted text to that of the text being replaced.
// returns the text.Edit for the inserted text.
func (tb *Buffer) ReplaceText(delSt, delEd, insPos lexer.Pos, insTxt string, signal, matchCase bool) *text.Edit {
	tbe := tb.Lines.ReplaceText(delSt, delEd, insPos, insTxt, matchCase)
	if tbe == nil {
		return tbe
	}
	if signal {
		tb.signalMods() // todo: could be more specific?
	}
	if tb.Autosave {
		go tb.autoSave()
	}
	return tbe
}

// savePosHistory saves the cursor position in history stack of cursor positions --
// tracks across views -- returns false if position was on same line as last one saved
