123 part - kenrube/Esopoly GitHub Wiki
123 is another language from the author of asdf, with even fewer instructions: there are only 3 of them.
Just like asdf, 123 generates a symbol code from individual bits and one instruction prints the entire 8-bit range. After reading the instructions, it's easy to come up with an algorithm for generating the symbol code:
- Moving to cell #7:
2222222 - If we want to invert the bit, call
1, otherwise121(there is no easy way to save the bit value without shifting) and shift to the left - Putting all 8 bits in this way, we'll be in cell #-1
- Calling
1, we move still to the left, to cell #-2 - We call
2that prints a character with an ASCII code whose binary representation is in cells 0-7, and will throw us into cell #0 - Repeat until readiness ...
- Call
1or121, setting the current bit to 0, and then 3, which finish the program.
Now it's easy to write the source code (for convenience, the generation of individual bits is divided by |):
2222222| 1|121|121|121| 1| 1|121|121| 1| 2| print '1' (00110001)
2222222| 1| 1|121|121|121|121|121|121| 1| 2| print '2' (00110010)
2222222| 1|121|121|121|121|121|121|121| 1| 2| print '3' (00110011)
2222222| 1| 1|121|121| 1|121|121|121| 1| 2| print ' ' (00100000)
2222222|121|121|121|121| 1|121| 1|121| 1| 2| print 'p' (01110000)
2222222|121| 1|121|121|121|121|121|121| 1| 2| print 'r' (01110010)
2222222| 1|121| 1| 1| 1|121|121|121| 1| 2| print 'o' (01101111)
2222222|121|121|121| 1|121|121|121|121| 1| 2| print 'g' (01100111)
2222222| 1|121| 1|121| 1|121|121|121| 1| 2| print 'r' (01110010)
2222222| 1| 1|121|121| 1|121|121|121| 1| 2| print 'a' (01100001)
2222222|121|121| 1| 1|121|121|121|121| 1| 2| print 'm' (01101101)

Let's unite all the languages that we have at the moment. Notice that Spoon has given us a lot of 1 instructions, which in 123 are escaped with jump instruction 3: 31 ... 13

As you can see, because of 123 the source code has grown a lot in size. You can check it in the author's interpreter (local copy).
