call clj

(call f & args)

Calls given function with supplied args in try/catch block, then calls ErrorHandling/handle on caught exception. If no exception has caught during function call returns its result

call-with clj

(call-with handler f & args)

Calls given function with supplied args in try/catch block, then calls handler on caught exception. If no exception has caught during function call returns its result

else clj

(else f value)

If value is a fail?, calls applies f to it, otherwise returns value

else-call clj

(else-call f value)

If value is a fail?, applies f to it wrapped to call, otherwise returns value

else-if clj

(else-if ex-class f value)

If value is an exception of ex-class, applies f to it, otherwise returns value

ErrorHandling clj protocol

Defines behavior for handling each class of exceptions

handle clj

(handle t)

fail clj deprecated

(fail)

(fail msg-or-data)

(fail msg data)

(fail msg data cause)

Calls ex-info with given msg(optional, defaults to nil), data(optional, defaults to {}) and cause(optional, defaults to nil). Deprecated, use ex-info instead

fail! clj deprecated

(fail! & args)

Constructs fail with given args and throws it. Deprecated, use ex-info with throw instead

fail-with clj

(fail-with {:keys [msg data cause suppress? trace?]
            :or {data {} suppress? false trace? false}
            :as options})

Constructs Fail with given options. Stacktrace is disabled by default

fail-with! clj

(fail-with! {:keys [trace?] :or {trace? true} :as options})

Constructs Fail with given options and throws it. Stacktrace is enabled by default.

fail? clj

(fail? t)

(fail? ex-class t)

Checks if value is exception of given class(optional, defaults to Throwable)

flet clj macro

(flet bindings & body)

Flow adaptation of Clojure let. Wraps evaluation of each binding to call-with with default handler (defined with ErrorsHandling/handle). If value returned from binding evaluation is fail?, it's returned immediately and all other bindings and body are skipped. Custom exception handler function may be passed as first binding with name :handler

then clj

(then f value)

If value is not a fail?, applies f to it, otherwise returns value

then-call clj

(then-call f value)

If value is not a fail?, applies f to it wrapped to call, otherwise returns value

thru clj

(thru f value)

Applies f to value (for side effects). Returns value. Works similar to doto, but accepts function as first arg

thru-call clj

(thru-call f value)

Applies f to value wrapped to call (for side effects). Returns value. Works similar to doto, but accepts function as first arg. Please not that exception thrown inside of function will be silently ignored by default
