TapeRun

TapeRun is a stack-based programming language which aims to take programmers back to a simpler time. The program consists of a tape, the has a command for each line, and one character is used as the alignment character, to ensure everything runs smoothly.

Here is the rundown of the tape commands.

  |# Take character as input onto the stack
# |  Output top of stack as character
##|  Pop top of stack
# |# Clone top of stack
 #|# Add to top of stack
 #|  Run until equal to value (represented in 3 bit binary until next separator, runs until the separator after that)
##|# Close for above statement

Since loops are a bit difficult to explain, here is an example:

 #|  Start loop
##|  6 +
##|  6 +
# |  4 =
##|# 16
 #|# Add one until the top of the stack is 16
##|# Close loop

Note that the binary representation of 6 is used instead of 7 because 7 is ##|#.

For comments the language will only take in the first 4 characters of each line, so any characters afterwards are ignored.

Here is now "Hello World!":
