Truth-machine
- 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.
- Repeat infinitely:
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.

Most dialects in this esolang are made to implement the Truth Machine easily.
Type 1 and Type 2 and Type 6 and Type 7 and Type 9 and Type 10
™
Type 3 and Type 5 and Type 8
The Truth Machine for type 3 and type 5 and type 8 are shorter than Truth Machine in any other language.
Type 4 and Type 11
It is impossible to write a Truth Machine in these dialects.

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:
,.[-->>+[<]<]<[.]
Brainfuck extended
_30~,~-~?_31[.]:_30.'
It is easy to write a truth machine in this language, because it has conditional operators.
This truth machine will treat characters that are not 0 as 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; } }
C++
Note: Extracted using Claude 3.5 Sonnet from File:Ternlsb_tm.png
#include<iostream> using namespace std; int main() { int a; cin>>a; if(a==0) { cout<<"0"<<endl; } if(a==1) { while(1) cout<<"1"<<endl; } return 0; }
C#
internal class Program { private static void Main(string[] args) { int a = Convert.ToInt16(Console.ReadLine()); if (a == 0) { Console.WriteLine(a); } else { while (a == 1) { Console.WriteLine(a); } } } }
Caca
youcaca newcaca zecaca? cacato12 nocaca? cacato12 yescaca cacaca49 icacac icaca cacato10 yescaca cacaca48 icacac icaca
Basically, it uses youcaca to ask for user input (Caca can only handle numbers as input), then, if the number is a 0 or a negative, it goes to the end using a cacato statement, which then outputs one 0 then stops, but if its positive, it then goes on to printing 1, then goes back and prints 1 using a cacato statement

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.)

Output can only occur if the program halts; in the case of 1-input, this program will produce an ever-expanding string of '1's.

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).

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.

There is such a thing as a truth machine. When a truth machine is to zero: There is a scribe called z. z is to write 0. When a truth machine is to one: There is a scribe called z. z is to write 1. I am to loop When a truth machine is to run a word: There is a linguist called l. l's first operand is the word. l's second operand is "0". l is to compare. If l says it's equal then I am to zero If l says it's not equal then I am to one When this program starts: There is a word called x. There is an inputter called y. y is to readOne x. There is a truth machine called t. t is to run x.

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.

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.)

is used.

Tables
Input index: "input"
Output index: "output"
If input is not 0
or 1
, the program will not do anything.
On zero, the program outputs 0
and terminates.
On one, the program outputs 1
and goes into an infinite loop (unable to set infinite indices of a table)

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.

This is an example of an implementation in a language that has no input facilities, only output. In the first parentheses, use !
for 1-input, and nothing for 0-input. The program below is calibrated for 1-input.

UnnumericJS
function truth_machine(input){ if(input==!''+!!''){ while(!''){ console.log(!''+!!''); } }else{ console.log(!!''+!!''); } }
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.
