Bash function to curl an HTTP JSON API, print the headers, and then print the body formatted using jq

jcurl.sh

# Bash function to curl an HTTP JSON API, print the headers,
# and then print the body formatted using jq
#
# Example usage: jcurl https://api.github.com/users/cirla

#function jcurl() {
  # disable progress bar and print headers to stdout
 # response=$(curl -sD - $@)
  
  # split response at the first empty line (ignoring whitespace)
  # sed on OS X neither recognizes \r as a special character nor matches
  # carriage returns with \s, so we have to insert a carriage return using printf
  #echo "$response" | sed "/^\s*$(printf '\r')*$/q"
  #echo "$response" | sed "1,/^\s*$(printf '\r')*$/d" | jq .
#}

## Updated to add more output control. 
## Some weird sed expressions cobbled together. Not a sed expert, if you know of a more simple or elegant way, let me know :) 
response=$( curl -sS -i https://www.metaweather.com/api/location/search/\?query\=new -w "\n\n%{time_connect},%{time_total},%{speed_download},%{http_code},%{size_download},%{url_effective}\n")
# Print headers
echo "$response" | sed "/^\s*$(printf '\r')*$/q"
# Print json 
echo "$response" | sed "$,/^\s$(printf '\r')*$/d" | sed "1,/^\s*$(printf '\r')*$/d" | jq '.'

# Print extra stats

echo "$response" | sed "1,/^\s*$(printf '\r')*$/d"   | sed "1,/^\s*$(printf '\r')*$/d"
