Smart quotes

Wrap string with quotes when a space, new line, or tab is present

# single quote
def smart_squotes($s): $s | if (test("[\\s\\n\\t]";"x")) then "\([39]|implode)\($s)\([39]|implode)" else $s end;

# double quote
def smart_dquotes($s): $s | if (test("[\\s\\n\\t]";"x")) then "\($s|@json)" else $s end;

$ jq -n -r '["hello","hello world","hello\nworld","hello\tworld"] | map("var="+smart_squotes(.))[]'
var=hello
var='hello world'
var='hello
world'
var='hello      world'

$ jq -n -r '["hello","hello world","hello\nworld","hello\tworld"] | map("var="+smart_dquotes(.))[]'
var=hello
var="hello world"
var="hello\nworld"
var="hello\tworld"
