header-args property

header-args property

[Michael Gauland]

I'm confused about the use of the header-args property. It works as
expected when I
export a file, but not when I evaluate a code block manually. For example,
consider this file:

    #+PROPERTY: header-args :var x="Hello" :exports both

    #+begin_src shell
      echo X is $x
    #+end_src

When I export, the result of the code block is "X is Hello", but when I
use C-c
C-c to evaluate the block in emacs, I get "X is"--the variable isn't
defined.

In practice, this means I generally define things like :session for each
block,
rather than using a file-level property. Is this behaviour expected? 

Kind regards,

Mike

This works for me on org 9.4.

I had trouble getting a file-level property to work across source blocks
before, but it worked in a property drawer. I thought this was going to be
that case, but I guess not. This seemed to work.

Did you hit C-c C-c on the property line to update org's view of the
properties set?  I think on export it will read these anew for the
export but executing C-cC-c on the src block will not pick up the value
unless you have re-initialized.
