Quine: build data (3)

Context

We now have an almost fully-function quine. We just have to convert to code into data.
And because of my monomania, this part itself will be done using BF :)
Initial state

• Memory: empty
• Cursor: first cell
• Input: some code to convert into data

Process

• First, generate + and > symbols
• Then, for each char read
• Print + as many times as the char value
• Then print >

Code - try it

generate PLUS and GT
++++++[->++++++++++>+++++++<<]>++>+
read cell
>,[
  print PLUS as many times as needed
  [-<.>]
  print GT
  <<.
  loop
  >>,
]

Final state

• Memory: 0 62 43 0 0 0 0
• Cursor: fourth cell
• Input: empty
• Output: our input code converted into data format
