Customize keymap prefix then rebuild keymap

[grettke]

Good evening Elias,

Attached is the change that rebuilds the keymap after the user changes the prefix along with my notes and testing results.

• gnu-apl-mode.el
  • Added a base-constructor to build the common keymap between edit and interactive mode
  • Added a constructor to build the edit keymap
  • Is not interactive because the defcustom doc string explains things
  • Uses the base keymap constructor
  • This code from yasnippet shows how to correctly handle referring to the perhaps not yet initialized value for the prefix. This was key to getting this defcustom setter working correctly
  • Added defcustom for prefix
  • Setter function sets using the default set-value and then rebuilds the keymap
  • The keymap is declared using the constructor
• gnu-apl-interactive.el (changes are virtually identical)
  • Added a constructor to build the keymap
  • Is not interactive because the defcustom doc string explains things
  • Uses the base keymap constructor
  • Added defcustom for prefix
  • Setter function sets using the default set-value and then rebuilds the keymap
  • The keymap is declared using the constructor

• Testing

  Mode	Buffer Open	Set prefix	Expectation	Result
  Edit file	No	Session	Set prefix when open, correct prefix	Pass
  Edit file	Yes	Session	Set prefix, close buffer, open file, correct prefix	Pass
  Edit file	No	Saved	Set prefix when open, correct prefix	Pass
  Edit file	Yes	Saved	Set prefix, close buffer, open file, correct prefix	Pass
  Interactive	No	Session	Set prefix when open, correct prefix	Pass
  Interactive	Yes	Session	Set prefix, close buffer, restart session, correct prefix	Pass
  Interactive	No	Saved	Set prefix when open, correct prefix	Pass
  Interactive	Yes	Saved	Set prefix, close buffer, restart session, correct prefix	Pass

Sincerely,

Grant Rettke
