Examples

Some examples showing the possibilities using functional-perl.

• fibs and primes show translations of Haskell programs.

• gen-csv and csv_to_xml (and the shorter variant csv_to_xml_short) show how to stream number series into and from CSV files and into XML.

• diff_to_html hows how to generate (X)HTML.

• skip shows how to implement a sliding window (look-ahead) as a pure function (that can easily be tested) and then uses it for I/O

• pdf-to-html is a practical, small and rather clean example reading directories and generating HTML. It also shows how to wrap non-functional Perl builtins (regex matching) in pure functions.

These are really just test suites, but perhaps still instructive:

• dbi shows/tests usage of FP::DBI

• predicates shows/tests FP::Predicates

• Htmlgen, the script that generates this website.

• For a real program using these modules, see ml2json, although it still bundles a much older version of the functional-perl libraries (todo: update to use the current functional-perl instead)
