Method Close

texteditor/buffer.go:491–544

Close closes the buffer, prompting to save if there are changes, and disconnects from editors. If afterFun is non-nil, then it is called with the status of the user action.

// from editors. If afterFun is non-nil, then it is called with the status of the user
// action.
