The camlp-streams package provides two library modules:
- Stream: imperative streams, with in-place update and memoization of
the latest element produced.
- Genlex: a small parameterized lexical analyzer producing streams of
tokens from streams of characters.
The two modules are designed for use with Camlp4 and Camlp5:
- The stream patterns and stream expressions of Camlp4/Camlp5 consume
and produce data of type `'a Stream.t`.
- The Genlex tokenizer can be used as a simple lexical analyzer for
Camlp4/Camlp5-generated parsers.
The Stream module can also be used by hand-written recursive-descent
parsers, but is not very convenient for this purpose.
The Stream and Genlex modules have been part of the OCaml standard
library for a long time, and have been distributed as part of the core
OCaml system. They will be removed from the OCaml standard library at
some future point, but will be maintained and distributed separately in
this camlp-streams package.
