Hi List, doing some Elisp programming (in an orgmode context) recently, the following question with regards to the 'accepted programming style' for Elisp concerned me:
How independent and self-sustained should helper functions be? I found some redundancy in elisp code, e.g. several (main and helper) functions that do exactly the same thing to extract the same specific args out of an argument list. My first reaction was, to factor out this extraction into the main function, and then call the helper functions from inside a (let ...) environment where the extracted args are stored in a local variable. But then I recognised, that the helper functions cannot be called independently anymore, but only make sense when called from this one main function with its local bindings. Is there a kind of convention in a case like this? Like: "Make every function, even a helper function, independent, and don't care about redundancy"? Just being curious cheers -- Thorsten
