I don’t know what it is about haikus that makes them so neat. Maybe it’s because they’re made up of prime numbers (3 lines, 5 syllables, 7 syllables, 5 syllables, a total of 17 syllables), or maybe it’s because you have so much beauty, artistry and emotion neatly packaged in just three lines. Either way, I think they are pretty neat.
I think I first got the idea to write a language based on haikus around two weeks ago when I was reading about esoteric languages. I was going over the Shakespeare Programming Language (SPL) (which I first heard about from a slashdot post a few years ago) when I started thinking about variations on the same theme (that is, prose or poetry as program code). I then thought “What if a haiku could also be program code?”. Thus, the idea of CherryBlossom was conceived. Initially, I was stumped as to how I could transform a haiku into program code. The structure of a haiku is rather rigid, and I couldn’t think of an easy way to make a language (with variables, functions, and flow-control) because of that rigidity. In comparison, SPL is much more free-flowing since it’s prose. In haiku, you are limited to the number of syllables and lines. Then I thought, “What if the language was minimalistic?”. In that case, all I need to do is figure out a way to map words to a small instruction set! When talking about languages with small (although not too small) instruction sets, there is no better candidate than Brainfuck, which is a Turing-Complete language with only eight instructions. With that in mind, I finally had an idea about CherryBlossom‘s implementation.
Like I mentioned before, the idea behind CherryBlossom is pretty simple. Brainfuck instructions are mapped to words that convey the meaning or essence of the Brainfuck instruction. For example, the > instruction, which moves the pointer forward conveys an essence of moving forward, or up. Hence it makes sense to map it to words that convey a similar meaning. With that idea, I came up with the following mappings:
|> (move pointer forward)||above, ahead, atmosphere, bird, birds, flew, flies, flight, float, floated, floating, floats, fly, flew, flying, forward, front, heaven, heavenly, height, high, higher, hill, hillside, hilltop, mountain, mountainside, mountaintop, push, pushed, pushes, pushing, rise, rises, rising, sky, top, up, upward, upwards (words that convey a sense of forward or upward motion, flying, or height)|
