01mf02/jaq v1.3.0

1.3

on GitHub

This release makes jaq a lot lazier. In particular, several core filters, such as debug, are now evaluated as late as possible #131, and filters passed to path expressions are now also executed lazily #150. That means that many filters which did not terminate before now terminate!

Backwards-compatible additions

Thanks go especially to @kklingenberg for implementing several new functionalities!

• Support for recursive object merging via a * b by @kklingenberg #130
• Add env filter and $ENV variables by @kklingenberg #128
• Extend path syntax to support paths like .a.[] #145
• group_by terminates as soon as there is an error #129

Breaking Changes

• The last(f) filter now returns no output instead of null when f yields no output. This is to make it consistent with first(f), which has the same behaviour. 51d3f51
• Rename --compact to --compact-output to match jq #148
• to_entries and paths now return objects without sorting keys, like jq 484dd27

Eliminated bugs

• Calling jaq without a filter now correctly executes the identity filter #147
• Calling jaq with an empty filter ('') now yields an error message instead of crashing, thanks to a new ariadne release --- thanks to @zesterer!
• Processing long sequences with foreach used to crash with a stack overflow at the end, for example when executing foreach limit(1000000; repeat(1)) as $x (0; .+$x). This is now not longer the case. 854d22c
