with-retry

with-retry^cljmacro

(with-retry initial-bindings & body)

It's really inconvenient not being able to recur from within (catch) expressions. This macro wraps its body in a (loop [bindings] (try ...)). Provides a (retry & new bindings) form which is usable within (catch) blocks: when this form is returned by the body, the body will be retried with the new bindings. For instance,

(with-retry [attempts 5]
  (network-request...)
  (catch RequestFailed e
    (if (< 1 attempts)
      (retry (dec attempts))
      (throw e))))
