Convert cURL command to Emacs Lisp code

Inspired by curl-to-Go: Convert curl commands to Go code.

(curl-to-elisp "curl example.com")
;; =>
(url-retrieve-synchronously "http://example.com")

(curl-to-elisp "curl -d 'hello world' example.com")
;; =>
(let ((url-request-method "POST")
      (url-request-extra-headers
       '(("Content-Type" . "application/x-www-form-urlencoded")))
      (url-request-data "hello world"))
  (url-retrieve-synchronously "http://example.com"))

To get started, try M-x curl-to-elisp curl -I example.com, the Emacs Lisp code will be pretty-printed in echo area.

Supported curl options

The following options are supported, other options are ignored.

Option	Note
-H, --header <header>
-I, --head
-X, --request <command>
-d, --data <data>	does not interpret @ as file
--data-ascii <data>
--data-binary <data>
--data-raw <data>
--data-urlencode <data>
-F, --form <name=content>	does not interpret @ as file
--form-string <name=string>
-A, --user-agent <name>
-e, --referer <URL>
--url <url>
-u, --user <user:password>	does not prompt for a password
-s, --silent

-L, --location

Regarding the location header, curl doesn't redirect unless you use -L, --location, however, url-retrieve[-synchronously] DOES automatically redirect, to inhibit redirection, let-binding url-max-redirections, e.g.,

(let ((url-max-redirections 0))
  (display-buffer
   (url-retrieve-synchronously "http://emacs-china.org")))

httpie to elisp

curl-to-elisp-httpie-to-elisp uses curlie to transform an httpie/curlie command to elisp.

You need to have curlie binary in your path (or customize curl-to-elisp-curlie-binary).

curl to verb

curl-to-elisp-verb converts curl command to verb request specification.
