Hello.
I have:
GNU Emacs 29.4 (build 1, x86_64-redhat-linux-gnu, GTK+ Version 3.24.43,
cairo version 1.18.2) of 2025-01-03 Org mode version 9.6.15 (release_9.6.15
@ /usr/share/emacs/29.4/lisp/org/)
In section "16.4 Environment of a Code Block" of the manual (from Info), I
read:
The following example shows how to reliably query and pass the file name of
the Org mode buffer to a code block using headers. [...]
#+BEGIN_SRC sh :var filename=(buffer-file-name) :exports both
wc -w $filename
#+END_SRC
I have a subtree containing just this code block:
#+BEGIN_SRC shell :var filename=("/tmp/test.r") :exports both
wc -w $filename
#+END_SRC
Upon 'C-c C-c', it gives
#+RESULTS:
: 1 /tmp/test.r
which is what I expect.
However, upon latex export of the subtree (C-c e l p), I get:
org-babel-read: Invalid function: "/tmp/test.r"
Now, if I remove the parentheses, i.e., if I just use
filename="/tmp/test.r" above, then it works as I expect in both cases, that
is, there is no error during export and I do see
wc -w $filename
1 /tmp/test.r
in the exported pdf file.
Are the parentheses in the manual correct? If so, what is the rationale?
Thanks.
