Hello, dup of https://github.com/jqlang/jq/issues/3078 and probably another reason why the online documentation should point to the latest release instead of development version 🤔

If you need a trim function in latest stable release you can define one something like this:

$ jq -n 'def trim: capture("^\\s*(?<s>.*?)\\s*$"; "m").s; " abc " | trim'
"abc"
