Sometimes a 'read-only' text property is stuck, and we cannot edit a file. This is the reason.

Json mode in emacs 29.1 seems to always place text as read only, and not let edit: “Text is read-only“. This describes the fix: (let ((inhibit-read-only t)) (set-text-properties (point-min) (point-max) ()))

Never before has a book been published that describes the techniques and technology used in writing text editors, word processors and other software. Written for the working professional and serious student, this book covers all aspects of the task. The topics range from user psychology to selecting a language to implementing redisplay to designing the command set.
