Insert variable into tangled source code

Insert variable into tangled source code

[Roland]

Hello!

I use orgmode to write code in a IA language developped by the company I 
work for. Everything was just nice when I attempted to insert in the source 
code a value set up in my org buffer.

Here is the real situation :


#+TBLNAME: tab_x
| x | 1 |

#+begin_src own_lang :tangle ./tangle_file :var x=x[0,1]
TYPE OBJ;

    CONSTANTE 
        var_x DOMAIN INTEGER DEFAULT $x
#+end_src

and I would except in tangle_file :
TYPE OBJ;

    CONSTANTE 
        var_x DOMAIN INTEGER DEFAULT 1

But unfortunately, I get 
TYPE OBJ;

    CONSTANTE 
        var_x DOMAIN INTEGER DEFAULT $x

Any ideas???

Thanks in advance.

Roland.

First, x[0,1] can't be resolved (unlike tab_x[0,1]).

For the rest, I'd guess you must add the proper replacemen "method" for
`own_lang'. Is this the case?

I mean: depending on the Babel language, variables must or must not be
prefixed by a $ sign to be replaced in the code block. For example, in Emacs
Lisp, you won't prefix vars with $.

Maybe have a look at `sh' or `sql' Babel languages for inspiration.

Best regards,

Thank you very much!!!

I've just adapted the SQL expand variable function in ob-sql.el to my 
language and it works perfectly!

Best regards.
