I don't see the gain over an int. people will always use a radios group or a selectbox for yes/no values so possible values are already filtered

and what if I want yes/no or 1/0 instead of true/false ? (like PHP filter_var() accept)

---

also this

!!(value.trim().toLowerCase() === "true")

is useless, same as

value.trim().toLowerCase() === "true"

(and is jshint compliant)

The use case I see this for is when you want to compare against a field of type boolean that ONLY contains true or false values. Currently there doesn't seem to be a way to do this (at least, I can't figure out how).

For example, I want to do a query and return only the records that contain the field 'foo' with a value of true.
A valid mongo query for this would look like:
{"$and":[{"foo":true}]}

Using int for this won't work, for example:
{"$and":[{"foo":1}]} (Returns 0 records)

Using string for this also doesn't work:
{"$and":[{"foo":"true"}]} (Returns 0 records)

ok I though Mongo accepts ints as bools

but you have a problem in the SQL plugin, without prepared statement the boolean is concatenated to the string, resulting in "true"/"false" and not "1"/"0" (it might work on MySQL but certainly not on others DBMS)

and with prepared statement I am not sure what will happen (depends on engine ?)

---

I won't merge until you or I find a nice solution to also accept (and convert) at least 0 and 1 as raw values

It would be nice if you could squash your commits when done (rebase -i then push --force)
