Extensions

This plugin comes with the following pxi extensions:

| | Description |
|---------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| line chunker | Divides data on line breaks. A lot of data formats like CSV, TSV, and JSON line build on this separation. |
| map applier | Applies pxi's functions to each individual line. Always returns a single result, unless an error is thrown during function application. |
| flatMap applier | Applies pxi'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 applier | Treats pxi'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 serializer | Serializes each transformed JSON into a string separated by newlines. |
