Parsing computer languages is often seen as an arcane, complex art only practiced by Computer Science PhDs to write compilers. But actually, tools exists to make writing parsers for computer languages or data formats much easier. And they're useful for much more than compiling - syntax highlighters, code formatters and simple error checkers (eg lint tools) are not that hard to write.
