Tiny is a small integer RPN based language created by User:Ron.hudson. It is a console/character type interpretive programming language, in which all statements are either assignments or those that print quoted strings.
Sounds like brainfuck with some extra arithmetic operations, but are there better loops?
You can do a loop by storing the “@” program counter in the stack, Performing the body and the check for exit, if exit then jump to next step after the loop, pop the “$” and store in “$” and “@” to return to the top of the loop. After the loop clean the stack by poping the stored top of loop address and discarding it.
$ cat hiloop 10 "Print a greeting 10 times \n" '%02d' 20 [10] c 30 [@] $ "top of loop will be the line after this one \n" 40 [c] ? " Hello World Greeting! \n" 50 [c 1 -] c 60 [c 0 = ! $ * ] $ @ 70 "Done \n\n" [$] 80 . $ tiny hiloop Print a greeting 10 times top of loop will be the line after this one 10 Hello World Greeting! 09 Hello World Greeting! 08 Hello World Greeting! 07 Hello World Greeting! 06 Hello World Greeting! 05 Hello World Greeting! 04 Hello World Greeting! 03 Hello World Greeting! 02 Hello World Greeting! 01 Hello World Greeting! Done Explained: 10 print a header and set output format 20 initialize counter 30 Push the address of the next step (@) onto the stack ($) and print a line to mark the top of our loop. 40 print the greeting with a helpful counter number 50 decrement the counter 60 if the counter has not reached zero go to the top of the loop, restoring the loop-top back to the stack 70 if 60 falls thru we are done, clean up the stack by poping once. 80 end of program sentinelI think it is much more expressive than BrainFuck.
btw. thanks for the example
You’re Welcome, I have yet to figgure out a good way to do a top exit loop (where the loop act zero or more times) w/o using a flag or jumping to a specific line number to exit.
i guess everything is much more expressive than brainfuck :D. But it reminded me of it when i first saw it
