Hey all. I'm pretty new to Clojure, and wanted to try my hand at
writing a macro.
'dowhile' is nothing special, but I'd still like to hear any comments/
suggestions you may have.
(defmacro dowhile [body test]
`(do ~body (while ~test ~body)))
A test shows...
(macroexpand-1 '(dowhile (dosync
I'd tend to code this so that the test was the first form, and then
any number of additional remaining forms become the body, in an
implicit do. Obviously, if you're writing something like this, its
for side effects.
In addition, I'd wrap the body in an annonymous function, defined in a
let, so
That does look better.
I had trouble with the anonymous func, however. After working it out,
here's what I think the problem is, as well as what I did about it.
~...@body expands the body (which is a list) so that the elements of the
list are represented without the surrounding parens.
