Extensions

This plugin comes with the following pf extensions:

	Description
line lexer	Divides data on line breaks. A lot of data formats like CSV, TSV, and JSON line build on this separation.
map applicator	Applies pf's functions to each individual line. Always returns a single result, unless an error is thrown during function application.
flatMap applicator	Applies pf's functions to each individual line. May return any number of results, including none, thus being able to change the length of a file.
filter applicator	Treats pf's functions as a conjunction of predicates and applies it to each individual line. If any predicate is false, the line is dropped, if all predicates return true, the line is kept.
string marshaller	Serializes each transformed JSON into a string separated by newlines.
