Download and unpack the compiler to get started! Modify the "input.txt" file with your sus programming input, and run sus.exe to compile it and view the output.
"Sus" is an esoteric programming language that is turing complete; think of it as an alternative BrainFuck. This was something I purely made in free time originally on the Roblox platform, but I decided to port it to the love2d framework in another set of free time for non-robloxians.
Like BF, this is based on an array and pointer. The pointer moves across an array and may increment/decrement values, and output that value as an ASCII character.
Sus is written with five symbols, which are documented below:
- ">" = Move pointer one spot forward in the array
- "<" = Move pointer one spot backward in the array
- "+" = Add to current pointer value
- "-" = Subtract to current pointer value
- "|" = Convert current pointer value to ASCII and add to output string
- "$" = If current pointer value is 0, skip past the next "!"
- "!" = Go back to the previous "$"
Any and all other characters are ignored when the program is compiled. Get creative with your code!
At the end of the code read, the interpreter prints the final output.
THE POINTER VALUE IS 97 BY DEFAULT! In a sense, this means each value in the pointer array will equal "a" as an ASCII value.
You shouldn't use it. It's useless.
Sus is an esoteric programming langauge. Esoteric programming languages are not intended for practical use in a program, but rather something for fun.
I recommend trying this out, though, if you would like to challenge your mind a bit, or impress a friend.
Here is an example printing "Hello world!":
-------------------------|>++++|>+++++++++++||>++++++++++++++|>-----------------------------------------------------------------|>++++++++++++++++++++++|<<|>>>+++++++++++++++++|<<<<|>>>>>+++|>----------------------------------------------------------------|
-------------------------|Go back to the ASCII value for "H," and add to output>++++|Go forward a cell, go to the ASCII value for "e," and add to output>+++++++++++|Go forward a cell, go to the ASCII value for "l," and add to output|The current pointer already equals "l," so just re-add it to the output>++++++++++++++|Go forward a cell, go to the ASCII value for "o," and add to output>-----------------------------------------------------------------|Go forward a cell, go to the ASCII value for space, and add to output>++++++++++++++++++++++|Go forward a cell, go to the ASCII value for "w," and add to output<<|A couple cells ago, we already defined the letter "o," so go back to it and print it>>>+++++++++++++++++|Go forward three cells, go to the ASCII value for "r," and add to output<<<<|We already defined a value for "l," so go back to that cell and print that value>>>>>+++|Go forward five cells, go to the ASCII value for "d," and add to output>----------------------------------------------------------------|Go forward a cell, go to the ASCII value for "!," and add to output
Also, per request of some acquaintances, here is an example that prints "chevvy":
++|>+++++++|>++++|>+++++++++++++++++++++||>++++++++++++++++++++++++|
One final example, prints "sus":
