Re: call to idiomatic loop works as stand alone but not when wrapped in my function
I would do it by making read-files-into-memory take a single argument, a list of filenames, rather than N arguments, each of which is a filename. Just drop the in the function's definition and you should be done.

Re: call to idiomatic loop works as stand alone but not when wrapped in my function
Thank-you, I think that works for me! I do need the to be able to take in a variable number of arguments, but it looks like I can call vec to convert this to a vector, then call the read-files-into- memory function that now will take a single argument. Such an elegant language but difficult to search for things like args or % or to find answers ;) Best, Avram On Apr 15, 1:10 am, Alan a...@malloys.org wrote: I would do it by making read-files-into-memory take a single argument, a list of filenames, rather than N arguments, each of which is a filename.

Re: call to idiomatic loop works as stand alone but not when wrapped in my function
You never need when you are defining your own functions. It's equivalent to declaring that your function takes one argument, a vector, and then always wrapping up in a vector whatever args you want to use.

Re: call to idiomatic loop works as stand alone but not when wrapped in my function
(defn read-files-into-memory [ filenames ] (print filenames) (map #(read-json-filename %1) filenames)) The [ filenames] argument spec turns all the arguments given into a sequence. You're not passing the filenames as separate arguments, but as a vector, so you either have to change that: (read-files-into-memory name1 name2 ..) or you need to use apply: (apply read-files-into-memory fnames) -- You received this message because you are subscribed to the Google Groups Clojure group.
