Filter inputs away about jq HOT 2 CLOSED

./jq 'if .foo == "bar" then empty end'

would do what you want. empty is a builtin that produces zero results. You can in theory implement it yourself with something like [][] (each element of an empty array).

You should probably use the (sadly undocumented) builtin function select instead:

./jq 'select(.foo == "bar")'

I intentionally didn't implement if-without-else, since I'm not sure whether the best default for "else" behaviour is produce-no-output or dont-change-the-input (that is, whether the implicit else block should be . or empty). This sounds like a vote for empty.

Ah. Brilliant. I don't think there's any need for if-without-else in the presence of select and empty. Closing this ticket because there's no issue with jq, just a gap in the docs. Cheers.
