Actually that does seem the most idiomatic approach
(def sources
{:bcc source("bbc.. ),
:google source("),
}
(defn all-sources []

I think Colin's record may be more detailed that just a key/value, he
mentioned 'simplified definitions' so I'm guessing there things elided from
the post.

could you not just use a map?
(def sources {:bbc "bbc.co.uk" :google "google.com" ...})

Would something like:
(def ^:dynamic *SOURCES* (ref []))
(defrecord Source [name url])
(defmacro defsource [name url]
`(dosync (alter *SOURCES* conj (Source. ~name ~url
(defn get-all-sources [] @*SOURCES*)
(defsource "Google" "google.com")
do ok?
Man - it's been too long since I've done c
Hi,
given a namespace sources
with [simplified definitions]
(defrecord Source [name url])
(def google (source "Google" "google.com"))
(def bbc (source "BBC" "bbc.co.uk"))
(def nbc ...
etc.
what would be the idiomatic way to implement
(defn get-all-sources)
cheers
Colin
