One thing I wish for in Charles (or maybe it’s there but hidden) is the ability to generate full working curl commands with all headers, cookies, and body data. I guess it can generate intermediate formats (I forget the name, h something) and then there are web sites that can convert that to curl but it would be nice to have it built in. Remember that it’s easy to copy/paste straight from iOS to macOS.
Yes, It's already supported in the Beta build :D. Select your request -> Menu on the Top-Right Nav -> Copy as cURL. Then you can straight paste to the Terminal on macOS
