I first define

#+NAME: 01H7T457WEWS07WD5T05BS5CN9
#+begin_src shell :results verbatim replace drawer :wrap src json
echo "foo"     
#+end_src

#+RESULTS: 01H7T457WEWS07WD5T05BS5CN9
#+begin_src json
foo
#+end_src

..and run it

#+begin_src shell :var _01H7STDXTTPR3GVA6ZJFCBJTWD=01H7T457WEWS07WD5T05BS5CN9 :results verbatim :noweb yes
curl -v 'https://gnu.org/test' \
     -H "Content-Type: application/json" \
     -H 'Authorization: Bearer '$_01H7STDXTTPR3GVA6ZJFCBJTWD''
#+end_src

, and I get

curl: (3) URL rejected: No host part in the URL

However, if I define within, it works fine.

#+begin_src shell :results verbatim
export _01H7T457WEWS07WD5T05BS5CN9="foo"
curl -v 'https://gnu.org/test' \
     -H "Content-Type: application/json" \
     -H 'Authorization: Bearer '$_01H7T457WEWS07WD5T05BS5CN9''
#+end_src

I'm not really sure what's happening here;) Am I typing it wrong?

  • I cannot reproduce it: both curl shell blocks produce the same output for me: #+RESULTS: : <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> : <html><head> : <title>301 Moved Permanently</title> : </head><body> : <h1>Moved Permanently</h1> : <p>The document has moved <a href="https://www.gnu.org/test">here</a>.</p> : <hr> : <address>Apache/2.4.29 Server at gnu.org Port 443</address> : </body></html>

  • Yes, it works, but this message is displayed in stderr, which is a window that pops up. Do you have a curl stderr window popping up?

  • What works? This message is the stdout of the command, not the stderr (do the commands in a terminal and see). I got rid of the -v which obscured the error output. The first one does indeed fail (with a different message: curl: (3) URL using bad/illegal format or missing URL) but that's because the value of the env variable includes a trailing newline. Do C-c C-v C-v on each code block to see what it expands to and cut and paste that into a terminal to debug.

  • Use echo -n "foo" in the first code block.

  • Ah, there is a newline appended to the end of it;) How come?

There is a newline appended, so to remove the newline:

#+begin_src shell :var VFY4O4ap1bRqbadlm7Rhe=W2rVuySIKascv2KRq6zY7 :results verbatim
curl -v 'https://gnu.org/test' \
     -H "Content-Type: application/json" \
     --header 'Authorization: Bearer '`echo $_01H7STDXTTPR3GVA6ZJFCBJTWD|tr -d '\n'`'' \
#+end_src

or use -n, as suggested;)

  • Or use echo -n as I suggested in a comment.
