Negate is an esolang idea by osminee where every value is either false or true (0 or 1, respectively).


In Negate there are following data types:

Type Code example Description
Bit b my_bit: !. Defines a variable with a value of either 0 or 1.
Array a char_a: (!-!!-!-!-!-!-!-!!). Defines an array consisting of bits.

Main syntax

Negate's main logic is about logical operators. For example, when you write !!, it means that you are negating a false value (essentially applying a NOT to the value), so it produces true.

Another example would be to perform a logical conjunction (AND) on two bits: b result: &[!-!!]. Here the value returned to result will be false.


As shown earlier, Negate does contain variables. You can define a variable like this:

<variable type> <variable name>: <value>.,


  • <variable type> - type of the variable (b for bit, a for array),
  • <variable name> - name of the variable (obvious),
  • <value> - desired value.
