editor-editable

editor <-> editable: bool

Boolean that indicates whether or not the text can be edited. If @off, a warning is generated whenever the user attempts to invoke an interactive command that would change the contents of the associated text_buffer.

See also editor->show_caret for hiding the caret on read-only editors.

BUG: In the original design, methods were fixed and methods

either implemented behaviour intended for user interaction or methods intended for program interaction. The editor->editable flag only affected interactive methods. Some of this distinction still remains. It is adviced to set editable to @on before modifying a read-only editor object from the program to avoid confusion.
