"Caca" is an esolang created by User:Mari on May 22nd, 2024. It's first interpeter is written in scratch. It's namesake and commands are based on a Discord server called "Progresscord"'s Humor, of saying "I caca", and sometimes using a sticker which is an edited version of Icoeye's logo with eyebrows, 1 eyebrow raised, a weird smirk and the caption "I caca" in the top corner in impact font. It is described as being "crappy and likely unfunny"
Commands
| Command (caca) | Command (nourmaelscript) | Description |
|---|---|---|
| icaca | out | print ascii character (of selected value) to screen |
| icacac | inc | add 1 to selected value |
| icac | dec | remove 1 from selected value |
| cacaca<INT> | repeat<INT> | loop line succeeding for value specified |
| icacan | sq | square the selected value |
| youcaca | input | ask user for input, numbers only (input is added to the selected value) |
| cacato<INT> | goto<INT> | jump to a specific line number |
| nocaca | prev | switch to previous value in caca stack |
| yescaca | next | switch to next value in caca stack |
| newcaca | addnum | add new value index to stack (there is 1 by default) |
| icaca? | ifp | execute line succeeding if selected value is positive |
| nocaca? | ifn | execute line succeeding if selected value is negative |
| zecaca? | ifz | execute line succeeding if selected value is 0 |
| cacacaca | copy | clone current selected value to stack |
Examples
this is a hello world program written in Caca:
cacaca72 icacac icaca cacaca3 icac icaca cacaca7 icacac icaca icaca cacaca3 icacac icaca cacaca47 icac icaca cacaca55 icacac icaca cacaca8 icac icaca cacaca3 icacac icaca cacaca6 icac icaca cacaca8 icac icaca
This code is mostly illegible, but basically it uses cacaca#### to run an increment(icacac)/decrement(icac) on loop, and it then uses icaca to print the ascii character corresponding with the value.
this is a truth machine:
youcaca newcaca zecaca? cacato12 nocaca? cacato12 yescaca cacaca49 icacac icaca cacato10 yescaca cacaca48 icacac icaca
as Caca code is, its mostly illegible. 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
Trivia
- Caca is (at least) the 2nd Esolang inspired by Progresscord, with the first being guh, however, Caca is implemented, while guh remains unimplemented. Also, Caca might be turing complete, while Guh is not due to lack of Conditional Execution.
- Originally, the command called 'zecaca?' was called 'nucaca?', but however scratch's bad word detector detected nucaca as a bad word so I had it changed to 'zecaca?'
- It is one of many languages to feature a Nope. Interpreter.
- Upgrades to Caca such as String Caca (Caca with strings), Absolute Caca (Caca with absolute number support, rather than all relative increments or decrements), and Caca Pro (Caca with improved control flow) do not actually exist.
- Despite the memory being called a Stack, its memory acts more like a Cell-based, rather than a stacking one
- A wimpmode for Caca exists called "nourmaelscript" which maps the caca instructions to human readable ones (listed in parenthesizes next to the canonical caca instructions). It has no execution difference.
