tool: add "variable" support Add support for command line variables. Set variables with --variable name=content or --variable name@file (where "file" can be stdin if set to a single dash (-)). Variable content is expanded in option parameters using "{{name}}" (without the quotes) if the option name is prefixed with "--expand-". This gets the contents of the variable "name" inserted, or a blank if the name does not exist as a variable. Insert "{{" verbatim in the string by prefixing it with a backslash, like "\\{{". Import an environment variable with --variable %name. It makes curl exit with an error if the environment variable is not set. It can also rather get a default value if the variable does not exist, using =content or @file like shown above. Example: get the USER environment variable into the URL: --variable %USER --expand-url = "https://example.com/api/{{USER}}/method" When expanding variables, curl supports a set of functions that can make the variable contents more convenient to use. It can trim leading and trailing white space with "trim", output the contents as a JSON quoted string with "json", URL encode it with "url" and base 64 encode it with "b64". To apply functions to a variable expansion, add them colon separated to the right side of the variable. They are then performed in a left to right order. Example: get the contents of a file called $HOME/.secret into a variable called "fix". Make sure that the content is trimmed and percent-encoded sent as POST data: --variable %HOME=/home/default --expand-variable fix@{{HOME}}/.secret --expand-data "{{fix:trim:url}}" https://example.com/ Documented.
