Not to be confused with Truth Machine (language), nor Turth-machine.

A truth-machine is a simple program type, devised by User:Keymaker to be a program that is easy, most of the time, to implement in a language, and useful for testing or showcasing the following capabilities of a language:

  • input
  • output
  • decision
  • repetition
  • termination

Essentially, a truth-machine works like this:

  • Ask for input.
  • If the input is 0:
    • Output 0.
    • Terminate program.
  • Whereas if the input is 1:
    • Repeat infinitely:
      • Output 1.

In languages without input capabilities, a truth-machine might instead have a simple way for the user to modify a variable or other structure in the beginning of the program, and the machine would do its decision based on that. A truth-machine in a language without output capabilities might simply either terminate or not terminate, based on the the input. The essence of a truth-machine is that some part of it, whether in the memory the program is using or in the program's code, may be either A or B, and the program contains the capacity (namely, program code) to do either of two possible things: in case of A the machine/program will perform an infinite loop, in case of B it will quit running. An alternative to output could be placing a 0 in memory once, or start filling the (infinite) memory with 1s.

Requires 3 files: main.2kwl, 1.2kwl, and 0.2kwl. Contents of main.2kwl:

print “\0”;
import ((“\0” == “1”) ? “1.2kwl”: “0.2kwl”);

Contents of 1.2kwl:

print “1”;
import “1.2kwl”;

Contents of 0.2kwl:

print “0”;

Type 1 and Type 2 and Type 6

Type 3 and Type 5

The Truth Machine for type 3 and type 5 are shorter than Truth Machine in any other language.


Type 4

It is impossible to write a Truth Machine in type 4.

I have a shorter one that needs negative cells:

,.[[-<+>>+<]>-]<<<[<<]>[.]

Another one based on subtraction(That is the simplest I can go)

,.[->+>+<<]++++++[->--------<]>[>[.]]

In versions where integer overflow wraps around, this 18 bytes machine is possible:

,.[-->+[>>]<[.]<<]

The first cell holds the input and the second cell will count up to P, the period of the overflow, where it will wrap back to zero. Given 0, subtracting 2 will cause the loop to cease. Given 1, it will loop P times, then ([>>]) is skipped, which causes (<[.]) to point at the first cell. After looping P times, 2P must be subtracted form the input n, but as P is the period, this means n - 2P mod P = n, thus 1 is printed forever.

There is also a 17 bytes version that needs negative cells:

,.[-->>+[<]<]<[.]

It is easy to write a truth machine with this language, because it has conditional operators.

This truth machine will treat characters that are not 0 as 1.

Bur doesn't have any form of input. Instead, change the character at index 24 to be 0 or 1:

A shorter example that tests 1 vs "anything else" rather than 1 vs 0. This time, the index in question is index 16:

Note that ByteByteJump, as more of a class of CPUs than a system, needs to be further described for a program. In particular, the version used here has 1-byte addresses. However, this program can be extended up to 5-byte addresses relatively trivially.

As for IO, 0xFF is assumed to be both an input and output port (having it pre-initialized and no output works just as well). Termination is handled via jumping to 0xFF, which implies 2 bytes of the instruction are out-of-range - the handling of this appears to be system-defined anyway (BytePusher handles this via zero-padding).

Finally, entering a character which is not '0' or '1' as the first character of input will fail horribly.

C

#include <stdio.h>
int main(a){
    scanf("%i",&a);
    if(a==1){
        while(1){
            puts("1");
        }
    } else{
        puts("0");
        return 0;
    }
}

In addition to fulfilling the tasks of a truth-machine, this program will experience mild satisfaction if the input is '0', and if the input is '1', it will feel extreme happiness (once) followed by mild distrust (an infinite number of times.)

May I take your order?

OK, how much money should Person 1 have?
Let's just do this until Person 1 has no more money!
Person 1 would also like the Vodka, hold the Truth Serum.

FurryScript

It does not do interactive I/O; output is only at the end and input is only at the beginning, so like Kipple and Squishy2K it won't work (unless perhaps, it can use lazy evaluation while knowing the stack effect in advance that it won't use up the data on the stack).

GetWhen

when(!input()): output(0), ip=%                //If input is 0, output 0 and terminate.
when(input()): output(1)                       //If input is 1, output 1 forever.

Note: This program would create a lot of unnecessary lines that are not executed. Below is a more memory efficient program:

1: x=input(), output(x), ip=x+2                //Output the input, then go to line 2 if it was 0 or line 3 if it was 1
2: ip=%                                        //Halt
3: output(1)

Since Jug has no input function, the second line "fill(0);" must be omitted (for 0) or not (for 1). Below, it is not omitted.

Kipple

Kipple only produces output if the Kipple program halts, so it is not possible to output an infinite number of 1 characters. However, the following program is probably a Kipple truth-machine in principle.

i>a-48 a? (a 49>o) 48>o

Kkipple

This program is very similar to its Kipple equivalent, but it actually works since Kkipple adds interactive I/O.

io>a-'0' a? (a '1'>o*) '0'>o*

The following truth machine takes inputs that are not multiples of seven as 1 and multiples as seven as zero. This makes 1 and 0 behave as expected, naturally. Making behaviour undefined for input other than 1 or 0 would have been much simpler, but I only thought of that after finishing the program.

SOS

This code actually ignores everything from the first byte of standard input except the lowest bit. Thus entering any ASCII character with even code will output a 0, and any ASCII character with odd codes will output an infinite string of 1s. Of course 0 has an even ASCII code, and 1 has an odd one.

As the language has no input, place 'Z' (for 0) or 'O' (for 1) inside the first {}. Below, 0 is used.

I{Z}
Z{\0}O{\1O}I

Squishy2K

Like the truth-machine in Kipple, this is only a truth-machine in principle, as the infinite string of 1's that is generated is never output (at least on the reference interpreter; the language afaik would not disallow implementations that lazily output the result.)

Using VIA library

Toggle bit 0 on the VIA to set the truth.

system(&BE6502);
include(&lcd);
<Since via.sc is already included in lcd.sc, we don't need to include it again.>

onreset({
  $lcd.init(&2l);
  if (?bit(#0), {
    forever ({
      $lcd.printchr(#'1');
    });
  },
  { halt(); });
});

Using PS2 library

Note: This uses the PS2 library, which isn't officially released yet.

system(&BE6502);
include(&lcd);
include(&ps2);

onreset({

Second row is the output clock, last row is the input. Using the recommended number encoding, replace ? in the last row with (input * 2 + 3), i.e. 3 for 0, 5 for 1. On 3(=0), the output clock will be set to 3(=0) and the program will cleanly exit. On 5(=1), the output clock will alternate between 5(=1) and 4(NaN?) without terminating.

        }

Since JavaScript has no input, UnnumericJS also has no input, so you have to pass !!''+!!'' for 0 and !''+!!'' for 1 to the truth_machine function.
