Is there a niffy way to trim values extracted from a form?

[Jacob Emcken]

I have extracted input form values, and trimming the entire map afterwards.

I was wondering if there is another (better way)?

I have been looking on wrapping (get-prop :value), but have been unsuccessful so far.

Jacob,

You could just use fmap to trim the values after read-form.

(let [form-vals (from "#formid" (read-form))

       trim-vals (fmap #(if (string? %) (.trim %) %) form-vals)]

      ...)

That is more or less what I do now.
I just explored the possibility to actually trim the values before they where put in the initial map to avoid traversing it later :)

Thanks for taking the time to answer this non-enfocus question.

Cheers,

Jacob,

If you want to eliminate that step to reduce code duplication you could wrap the read-form extractor.  

(defn read-form-trimmed []

  (fn [node] 

     (fmap #(if (string? %) (.trim %) %) 

      (from node (read-form)))))

  

;then we can use it as an extractor

(from "#form-id" (read-form-trimmed))
