Hi!
Some vim options are boolean, i.e. integers with the possible values 0
and 1. You can, e.g., set `ai` and `noai` or use `let &ai = 1`. Other
options are numeric/integer or string values.
type(&option) can only be used to distinguish string from bool/int
options. exist('&noai') returns 0, so it cannot be used to distinguish
bool from int options. Is there another way to determine whether an
option is a bool (an int that takes only the values 0 or 1) or an int?
Some hacks, I can think of:
- parsing $VIMRUNTIME/doc/options.txt
- try/catch block around :set inv<option>
BTW: What is the problem with treating boolean options like integer?
Best,
Christian
