[babel] Globally assigning a value to a variable

[babel] Globally assigning a value to a variable

[Sebastien Vauban]

#+PROPERTY:  var myvar="original"

* Overview

I would like to test a global variable assignment (just done here above) and
local ones (on the code block itself). It seems that the global value is not
"known". Though, maybe, I don't understand it fully yet.

* Test code

** Using the local var

  #+srcname: test-local
  #+begin_src sh :var myvar="canada-dry"
  echo $myvar
  #+end_src

  #+results: test-local
  : canada-dry

** Using the global var

I'm not passing anymore a local value, hence expecting the "global" value to
be used:

  #+srcname: test-global
  #+begin_src sh :var anothervar="canada-dry"
  echo $myvar
  #+end_src

  #+results: test-global
  (no output)

Am I understanding correctly how it works / should work?

Best regards,
  Seb

I think so and it works for me. Does C-c C-c on the #+PROPERTY: line and
reevaluating the block help?

Thanks for testing.

Of course, I just missed that. Thanks, and sorry for the noise...
