Ideally, we'd have a defcustom `org-crypt-auto-save' with the following options:
- 'ask : Ask the user whether or not to decrypt the entry.
- 'disable : Disable auto-save-mode for the current buffer before decrypting.
- 'ignore : Decrypt the entry regardless.
- 'encrypt : Re-encrypt the entries before auto-save kicks in.
I've implemented this, but it fails miserably:
Since the function `auto-save-mode' doesn't set an buffer-local
var to indicate whether or not it's enabled for the current buffer, we
can only check for `auto-save-default'. This poses the following problems:
- 'ask will be a serious whiner, prompting the user for each and every
entry being decrypted, whether or not `auto-save-mode' is enabled for
the current buffer.
- 'disable will cause (perhaps minor) performance issues, since it will
try disabling `auto-save-mode' for each and every entry being decrypted,
even though it may already be disabled for the current buffer.
If (as per your suggestion) emitting a warning, this will also spam the
*Message* buffer to no end.
Also, 'encrypt will simply not work, due to `auto-save-hook' not being
called when it's supposed to.
BTW: For those of us running `org-decrypt-entry' with a wrapper function,
do remember one has to call (auto-save-mode -1) instead of (auto-save-mode nil),
since the latter will *toggle* instead of *disable* !
