// 1. Create a table on Airtable, and make URL/text columns with these names:
//        URL, Title, Description, Image, Feed
//    
// 2. Add a Form view. Click "Open form", then copy the URL. Set `airtable_form_url`
//    below to that URL.
//
// 3. Create a new bookmark in your web browser, and paste in the code below. Whenever
//    you're on a page you want to save, click the bookmark ("bookmarklet", technically).
//    You'll go to the airtable form, and the columns listed above will be prefilled.

Say you define a composite tuple like so:

#:db{:ident :foo,
     :valueType :db.type/tuple,
     :unique :db.unique/identity,
     :tupleAttrs [:bar :baz],
     :cardinality :db.cardinality/one}

Now suppose you want to change [:bar :baz] to [:bar :quux]. The [Datomic

If you call clojure.tools.namespace.repl/refresh before requiring any namespaces referenced in data_readers.clj, then *data-readers* gets messed up somehow. The readers you define in data_readers.clj won't work even if you require their namespaces. For example:

$ find -type f
./src/foo/core.clj
./src/data_readers.clj
./src/user.clj

On a project I'm working on, this gives me an error:

$ clj -Sdeps '{:deps {trident/build {:local/root "/home/arch/dev/trident/target/build"}}}' \

Exception in thread "main" Syntax error compiling at (trident/build/util.clj:1:1).

(I have (:import (jnr.posix POSIXFactory))) in that file).
