Severity: wishlist
I'd like a way to mark a variable as safe only when read from a
particular directory or file.
I create a .dir-locals.el file with some unsafe variable, e.g.
tmp=`mktemp -d`
echo "((nil . ((epa-file-cache-passphrase-for-symmetric-encryption . t))))" \
> $tmp/.dir-locals.el
echo $tmp
Now I visit a file in the created directory and get this message:
The local variables list in /tmp/tmp.qakuGgnFPH/
contains values that may not be safe (*).
Do you want to apply it? You can type
y -- to apply the local variables list.
n -- to ignore the local variables list.
! -- to apply the local variables list, and permanently mark these
values (*) as safe (in the future, they will be set automatically.)
i -- to ignore the local variables list, and permanently mark these
values (*) as ignored
* epa-file-cache-passphrase-for-symmetric-encryption : t
According to (info "(emacs) Safe File Variables"), hitting "i" means
that:
You can also tell Emacs to permanently ignore all the variable/value
pairs in the file, by typing ‘i’ at the confirmation prompt – these
pairs will thereafter be ignored in this file and in all other files.
I would like to be able to mark this variable/value pair as safe *only*
when read from this file, and not in any file.

Yes, that sounds like a good idea to me.
