Re: [O] Referring to an Org Babel variable in the invocation arguments to another Org Babel code block

But you simply cannot do that. `(info "(org) var")' tells us what you can do: #+BEGIN_QUOTE The following syntax is used to pass arguments to `src' code blocks using the `:var' header argument. :var name=assign The `assign' is a literal value, such as a string `"string"', a number `9', a reference to a table, a list, a literal example, another code block (with or without arguments), or the results from evaluating a code block. #+END_QUOTE The `name' of one argument is none of these (regardless of its effect when the body of the src block is executed, which BTW depends on the src block language). There are other approaches that might serve a purpose in babel src blocks like that served by `let*' in lisp: - putting variables in a table (possibly invoking `org-sbe' in a formula) and then referencing table cells - writing other src blocks to handle the preliminary processing and referncing them - writing an elisp src block that does those preliminaries (perhaps using `org-babel-ref-resolve' to call other src blocks), then builds a string specifying a call to your shell src block and calls it using `org-babel-ref-resolve'. - using a noweb reference that executes another src block (or blocks). - setting property values and referencing them You might have better luck getting guidance on a useful approach by trying to describe what you want to accomplish.

Hi Nicolas, I tried "c", and it gives me: >>> c <<< as the result. I would like it to use the _variable_ "c", not the literal string. So the result should be ">>> test <<<" I've also cleaned up the Org I made (something went wrong when I pasted it before, it missed an #+END_SRC) Thanks! #+NAME: block-1 #+BEGIN_SRC shell :var x="X" echo ">>>" $x "<<<" #+END_SRC #+END_SRC #+BEGIN_SRC shell :var c="test" y=block-1("c") echo $y #+END_SRC #+RESULTS: : >>> c <<< On 12/29/2016 03:49 PM, Nicolas Goaziou wrote: >> #+NAME: block-1 #+BEGIN_SRC shell :var x="X" echo ">>>" $x "<<<" >> #+END_SRC #+BEGIN_SRC shell :var c="test" y=block-1(c) echo $y >> #+END_SRC #+RESULTS: : >>> $c <<<

Re: [O] Referring to an Org Babel variable in the invocation arguments to another Org Babel code block
Hi Charles, I think I found precisely the issue I'm having. When I use your example, and adjust it slightly: #+NAME: block-1 #+BEGIN_SRC shell :var x="X" echo ">>>" $x "<<<" #+END_SRC #+BEGIN_SRC shell :var c="test" y=block-1(c) echo $y #+END_SRC #+RESULTS: : >>> $c <<< I added a reference to an argument defined within the same block. I get the aforementioned error: org-babel-ref-resolve: Reference ācā not found in this buffer Thanks! Zack
