USER_DELETED and USER_INACTIVE are bit flags. An integer can hold many bit flags (typically, 32). In the case of user.settings, each bit as a pre-defined purpose and those bits have been assigned symbolic names (in userdefs.js).

To set (add) a bit-flag, you bit-wise "OR" it into the value, like so:

user.settings |= USER_DELETED;

To unset (remove) a bit-flag, you bit-wise "AND" it with the opposite (bit-wise not) value, like so:

user.settings &= ~USER_DELETED;

Hope that helps,

user.settings &=~ USER_DELETED;

interesting ... that &=~ ... undeletes? no wonder USER_DELETED = 0 didn't work ... thought it was a BOOLEAN o.o

It unsets a bit (or a set of bits). In this example, it's unsetting the "USER_DELETED" bit.

no wonder USER_DELETED = 0 didn't

Nope. jsobjs.html is you friend. :-)

as learning any language ( obviously I am not C adept) what does ~& or even just ~ mean negate a bitwise?

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators

'~a' inverts the bits of 'a'

'a & b' returns ones in positions where both 'a' and 'b' have ones

'a & ~b' returns ones in positions where both 'a' and the inverse of 'b' have ones

'a &= b' assigns the result of 'a & b' to 'a'

'a &= ~b' assigns the result of 'a & ~b' to 'a'

'a | b' returns ones where either 'a' or 'b' have ones

'a |= b' assigns the result of 'a | b' to 'a'

So:

var a = 1; // 00000001
var b = 2; // 00000010
a |= b; // a = 00000001 | 00000010
a &= ~b; // a = 00000011 & 11111101

if that makes sense.

huh! starting to ... kinda reminds me of 8 bit assembly, thank you, waking my brain up again after years of octal sleep :-o
