Crate jaq_std

Standard library for a JSON query language.

The standard library provides a set of filters. These filters are either implemented as definitions or as functions. For example, the standard library provides the map(f) filter, which is defined using the more elementary filter [.[] | f].

If you want to use the standard library in jaq, then you’ll likely only need funs and defs. Most other functions are relevant if you want to implement your own native filters.

Traits

ValT

Values that the core library can operate on.

Functions

base_funs

Minimal set of filters that are generic over the value type. Return the minimal set of named filters available in jaq which are implemented as native filters, such as length, keys, …, but not now, debug, fromdateiso8601, …

defs

Definitions of the standard library.

extra_funs

Supplementary set of filters that are generic over the value type.

funs

Named filters available by default in jaq which are implemented as native filters, such as length, keys, …, but also now, debug, fromdateiso8601, …

run

Convert a filter with a run pointer to a native filter.

unary

Create a filter that takes a single variable argument and whose output is given by the function f that takes the input value and the value of the variable.

v

Creates n variable arguments.

Type Aliases

Filter

Name, arguments, and implementation of a filter.
