0.8.0

What's Changed

The largest addition in this release is support for complex assignments: Previously, the left-hand side of assignments in jaq were restricted to simple path expressions, such as .[], .a. Now, jaq also supports assignments with more general left-hand sides, such as if .. then .. else .. end, recurse(..) and several others. This enables filters such as (.posts[] | select(.author == "stedolan") | .comments) |= . + ["terrible."] (taken from the jq manual --- I do not have such strong feelings towards Stephen Dolan's posts ^^).

This release also adds support for several new filters:

• inputs, input: These filters make it now possible to process input lazily with state. This effectively makes jaq an impure programming language --- but impurity is restricted to modifying the stream of input values.
• foreach xs as $x (init; update): This is a powerful tool, in particular in conjunction with inputs. For example, foreach inputs as $x (null; .+$x) builds a cumulative sum of the input elements, lazily.
• ..: shorthand for recurse(.[]?)
• while, until: thanks to @capezotte

Smaller changes include:

• Configurable color usage via --color
• Escaped characters in strings: It is now possible to write something like "\"".
• Increased compatibility with jq: thanks to @itchyny for finding several places where jq and jaq diverged
• Homebrew installation, thanks to @chenrui333
