You might think of interpreters as only good for writing programs. Many people learned programming on some kind of interpreter — like BASIC — because you get immediate feedback and don’t have to deal with the complexities of a compiler. But interpreters can have other uses like parsing configuration files, for example. [Sakib] has a very complete tutorial about writing an interpreter in Scala, but even if you use another language, you might find the tutorial useful.
We were impressed because the tutorial uses formal parsing using a lexer and a parser. This is how you’d be taught to do it in a computer science class, but not how everyone does it.
