Hi Jeff,
Don't forget that Velocity and Freemarker are also good candidates for
server side templating and with clojure's java integration a snap to
use, e.g. ...
(defn genSyntaxHiLight
[] (let [fmc (freeMarkerConfig)
tmpl (. fmc getTemplate "clojure.ftl")
map (clj-ns/get-tree)
]
(. tmpl process (convertMap map) *out*)
))
the clojure.ftl is a free marker template. I think that with clojure's
maps implementing Map that the (convertMap) I had required previously
is no longer necessary.
