(fail category & more)Construct a new anomaly with the given category. Accepts either keyword
arguments or a map with further data.
Example: (= [::anomaly :nonono {:foo 1 :bar 2}]
(fail :nonono :foo 1 :bar 2)
(fail :nonono {:foo 1 :bar 2}))
Construct a new anomaly with the given `category`. Accepts either keyword
arguments or a map with further data.
Example: (= [::anomaly :nonono {:foo 1 :bar 2}]
(fail :nonono :foo 1 :bar 2)
(fail :nonono {:foo 1 :bar 2}))let-nomclj/smacro
(let-nom bindings & body)Like a let, but each binding is made anomaly-propagating with nom. Any
binding that assigns to a single symbol whose name starts with an underscore
is treated as a guard. If the form in a guard is a vector, its constituent
forms are checked one-by-one as in with-nom. If a guard finds an anomaly,
the bindings short-circuit at that point, so no further binding nor the body
are executed, and the value of the entire let-nom form is that anomaly.
This means that if you want to recover from an anomaly in the body, you should
not use guards.
Like a `let`, but each binding is made anomaly-propagating with `nom`. Any binding that assigns to a single symbol whose name starts with an underscore is treated as a guard. If the form in a guard is a vector, its constituent forms are checked one-by-one as in `with-nom`. If a guard finds an anomaly, the bindings short-circuit at that point, so no further binding nor the body are executed, and the value of the entire `let-nom` form is that anomaly. This means that if you want to recover from an anomaly in the body, you should not use guards.
let-nom>clj/smacro
(let-nom> bindings & body)Like let-nom, but any binding of an anomaly short-circuits, so that no
further binding nor the body are executed, and the value of the entire
let-nom> form is that anomaly. This means that you cannot recover in the
body from anomalies in the bindings.
Like `let-nom`, but any binding of an anomaly short-circuits, so that no further binding nor the body are executed, and the value of the entire `let-nom>` form is that anomaly. This means that you cannot recover in the body from anomalies in the bindings.
nomclj/smacro
(nom & forms)Macro version of nom*. Checks all the values given in the form. If any
value is an anomaly, returns that anomaly. Otherwise, evaluate the rest of
the form (without the nom).
Example: (nom foo bar) — if any of nom, foo, or bar is an anomaly, returns that; otherwise calls and returns (foo bar).
Because this is a macro that expands to a conditional and the wrapped form, arities are checked normally by compiler and runtime.
Macro version of `nom*`. Checks all the values given in the form. If any value is an anomaly, returns that anomaly. Otherwise, evaluate the rest of the form (without the `nom`). Example: (nom foo bar) — if any of nom, foo, or bar is an anomaly, returns that; otherwise calls and returns (foo bar). Because this is a macro that expands to a conditional and the wrapped form, arities are checked normally by compiler and runtime.
nom*clj/s
(nom* f & args)Takes a function f and arguments args for it. Checks all args. If any
of them is an anomaly, returns that. Otherwise, returns the result of
applying f on args.
Takes a function `f` and arguments `args` for it. Checks all `args`. If any of them is an anomaly, returns that. Otherwise, returns the result of applying `f` on `args`.
nom->clj/smacro
(nom-> form & forms)Like some->, but instead of nil short-circuits on any anomaly.
Like `some->`, but instead of `nil` short-circuits on any anomaly.
nom->>clj/smacro
(nom->> form & forms)Like some->>, but instead of nil short-circuits on any anomaly.
Like `some->>`, but instead of `nil` short-circuits on any anomaly.
some-abominationclj/s
(some-abomination x)Returns an anomaly from x if it is an anomaly or abominable, else nil.
Returns an anomaly from x if it is an anomaly or abominable, else nil.
with-nomclj/smacro
(with-nom vs & body)Takes a vector of forms to check and a body. If any of the checked forms returns an anomaly, the rest of the forms and the body are not executed and the anomaly returned.
Takes a vector of forms to check and a body. If any of the checked forms returns an anomaly, the rest of the forms and the body are not executed and the anomaly returned.
