Bug: Cannot tangle bash source blocks [9.0 (release_9.0-237-gccf2b9 @ /usr/local/share/emacs/site-lisp/org/)]

[David Dynerman]

I cannot tangle a bash source block (via ob-shell) that contains
variables. To reproduce, enter this into an org file:

#+BEGIN_SRC bash :var HELLO="world" :tangle
echo $HELLO
#+END_SRC

Then C-c C-v t RET

This error is reported:

org-babel-tangle-single-block: Wrong number of arguments: (2 . 4)

No tangled output is produced. I can reproduce this in emacs -Q loading
a current version of org (237-gccf2b9) by executing the following first:

(add-to-list 'load-path "/usr/local/share/emacs/site-lisp/org")
(require 'org)
(require 'ob-shell)

This bug doesn't seem to apply to 8.2.10, since that version used ob-sh.

The :tangle keyword requires an argument, one of 'yes', 'no', or a path.

But I think your error message (which I can reproduce) is due to using
'bash' instead of 'shell' for the language of the source code block.

This works for me:

#+BEGIN_SRC shell :var HELLO="world" :tangle bash.sh
echo $HELLO
#+END_SRC

hth,
Tom

Fixed. Thank you.
