Programming is hard. Making compilers is harder. Or so people think. The truth is that making a compiler is just a series of small steps, using regular language constructs. It's so easy, we'll make one in this session. Many developers (especially those who are self-taught) believe the lie; that making compilers is too hard for them. That they lack the tools and knowledge to bring their ideas about programming languages to life. There's a lot of complex thinking that goes into mainstream compilers, but that's no reason not to try! We can make less efficient compilers and interpreters which enable the same amount of power and flexibility as mainstream compilers. We could use tools like Parser Expression Grammars or JISON, but this session will look at something even simpler. Let's build our own cross compilers using regular expressions and a stack. Let's implement our own programming languages, in real-time.
