Module data 

The data steps (RFC 0027 §5 “Data”): array and text operations without a model — map, filter, reduce, sort, dedupe, chunk, parse — as pure functions over JSON values. Element expressions are CEL (item, index, acc, plus the run data) or {{template}} strings; by keys are dotted paths.

Functions

chunk

chunk: split text by chars|lines|tokens (approximate) or an array into slices of size, with overlap elements/chars carried over.

cmp_values

A total order over JSON values: null < bool < number < string < array < object.

dedupe

dedupe: keep the first occurrence per key (by path) / value.

filter

filter: keep the elements whose expr is true.

map

map: expr over every element.

parse

parse: text → JSON (json | yaml | csv | lines | auto).

path_of

A dotted path inside a value.

reduce

reduce: fold expr over the elements with acc (starting at initial).

sort

sort: by a dotted path (or the element itself), asc|desc; stable.
