Hiccup with Sequence
Hi all, I'm trying to output the items from a sequence into a HTML list using the Hiccup HTML builder, but am having problems. Here is the code I think 'should' work, but nothing after the ':ul' is passed back to the response: (html [:html [:body [:ul (doseq [item myseq] [:li item]) ] ] ] ) Can anyone see why this is not working?

Re: Hiccup with Sequence
doseq do not return anything. (It is for side-effect only). You might be looking for 'for'. (doc for) - clojure.core/for ([seq-exprs body-expr]) Macro List comprehension. Takes a vector of one or more binding-form/collection-expr pairs, each followed by zero or more modifiers, and yields a lazy sequence of evaluations of expr. Collections are iterated in a nested fashion, rightmost fastest, and nested coll-exprs can refer to bindings created in prior binding-forms. Supported modifiers are: :let [binding-form expr ...], :while test, :when test. (take 100 (for [x (range 1) y (range 100) :while ( y x)] [x y])) On Mon, Sep 27, 2010 at 11:25 AM, Paul paul_bow...@yahoo.com wrote: Hi all, I'm trying to output the items from a sequence into a HTML list using the Hiccup HTML builder, but am having problems.
