Hyperbole link:
{C-h f defcustom RET}
where it says:
This macro calls ‘custom-declare-variable’. If you want to
programmatically alter a customizable variable (for instance, to
write a package that extends the syntax of a variable), you can
call that function directly.
Hyperbole link:
{C-h f custom-declare-variable RET}
(custom-declare-variable SYMBOL DEFAULT DOC &rest ARGS)
Like ‘defcustom’, but SYMBOL and DEFAULT are evaluated as normal arguments.
DEFAULT should be an expression to evaluate to compute the default value,
not the default value itself.
That way you can programmatically change variables created by
`defcustom'.
