Unconditionally executes given form and- If form succeeds: return the form's result. If form throws: Call `error!` with the thrown error and the given signal options [1], then return (:catch-val opts) if it exists, or rethrow the error. API: [form] [id-or-opts form] => form's result (value/throw) (unconditional), or (:catch-val opts) Default kind: `:error` Default level: `:error` Examples: (catch->error! (/ 1 0)) ; %> {:kind :error, :level :error, :error ...} (catch->error! {:id ::my-id, :catch-val "threw"} (/ 1 0)) ; %> {... :id ::my-id ...} (catch->error! {:let [x "x"] ; Available to `:data` and `:msg` :data {:x x} :msg_ ["My msg:" x]} (/ 1 0)) ; %> {... :data {x "x"}, :msg_ "My msg: x" ...} Tips: - Test using `with-signals`: (with-signals (catch->error! ...)). - Supports the same options as other signals [1]. - Useful for recording errors in forms, futures, callbacks, etc. See also `error!`.
