I imagine for small languages a lot of people roll their own parser,
using the "the grammar is the program" idiom as demonstrated (for
example) in one of the final chapters of Paulson's ML book. That's what
I've done a couple of times in various functional languages. This
approach is simple to write (educational, too, the first time you do
it) but not particularly fast.
Then there is the parsec project which is a considerably more serious
implementation of combinator based parsing.
