The long journey from character to AST... begins elsewhere


Since we’re in full compiler-compiler season I thought it would be appropriate for me to also provide a more educational example. This example illustrates how a very rudimentary* compiler works. In more detail, it shows what happens to your code after it’s been chopped into nice tokens. Then, it shows how, based on these tokens and the language’s grammar an AST is built and then decorated and, finally, how this tree is fed to an interpreter and results start popping up.

By rudimentary I mean that the language consists of simple arithmetic expressions. Below, you can find the compiler-demo. Just type stuff and be amazed!

If you want to find out more about the inner workings of this nifty thing, check this very nicely written article on CodeProject.

<div> Your input code:
7 + pi * (x - 10)
The environment:
{ “x” : 5, “pi” : 3 }
Output:
</div>

These are background sprites I've created for a game I'm working on at school ^w^ Click on the post to see how the sprites connect. You won't regret it! (personally, I think it's pretty heheh)

Drawn in Piskel using my mouse. Whaddya think?

I did this on my 3DS ^^ #Kirby
