*catch-from*clj
Base exception class which will be caught by call. Dynamic, defaults to Throwable. Use catch-from! or catching to modify
Base exception class which will be caught by `call`. Dynamic, defaults to `Throwable`. Use `catch-from!` or `catching` to modify
*default-handler*clj
Default handler for processing caught exceptions. When caught an exception
which class is *catch-from* or a subclass of it, and is not listed in *ignored-exceptions*(and is not a subclass of any classes listed there)
returns instance of caught exception, otherwise throws it
Default handler for processing caught exceptions. When caught an exception which class is `*catch-from*` or a subclass of it, and is not listed in `*ignored-exceptions*`(and is not a subclass of any classes listed there) returns instance of caught exception, otherwise throws it
*ignored-exceptions*clj
Exception classes which will be ignored by call. Dynamic, defaults to empty set. Use ignore-exceptions!, add-ignored-exceptions! or ignoring to modify
Exception classes which will be ignored by `call`. Dynamic, defaults to empty set. Use `ignore-exceptions!`, `add-ignored-exceptions!` or `ignoring` to modify
add-ignored-exceptions!clj
(add-ignored-exceptions! ex-class-set)Adds given set of classes to *ignored-exceptions*
Adds given set of classes to `*ignored-exceptions*`
callclj
(call f & args)Calls given function with supplied args in try/catch block, then calls *default-handler* on caught exception. If no exception has caught during function call returns its result
Calls given function with supplied args in `try/catch` block, then calls `*default-handler*` on caught exception. If no exception has caught during function call returns its result
call-withclj
(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
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
catch-from!clj
(catch-from! ex-class)Sets exception-base-class to specified class
Sets *exception-base-class* to specified class
catchingcljmacrodeprecated
(catching exception-base-class & body)Executes body with *exception-base-class* bound to given class.
Deprecated due to possible problems with multi-threaded code. Use call-with to achieve same behavior with thread-safety
Executes body with `*exception-base-class*` bound to given class. Deprecated due to possible problems with multi-threaded code. Use `call-with` to achieve same behavior with thread-safety
elseclj
(else f value)If value is a fail?, calls applies f to it, otherwise returns value

else-ifclj
(else-if ex-class f value)If value is an exception of ex-class, applies f to it, otherwise returns value

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

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

fail-withclj
(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
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)
Checks if value is exception of given class(optional, defaults to Throwable)
fletcljmacro
(flet bindings & body)Flow adaptation of Clojure let. Wraps evaluation of each binding to call-with with *default-handler*. If fail? value returned from binding evaluation, it's returned immediately and all other bindings and body are skipped. May use custom exception handler passed as first binding with name :handler

ignored?clj
(ignored? t)Checks if exception should be ignored

ignoringcljmacrodeprecated
(ignoring ignored-exceptions & body)Executes body with *ignored-exceptions* bound to given value.
Deprecated due to possible problems with multi-threaded code. Use call-with to achieve same behavior with thread-safety

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

thru-callclj
(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
