ablauf.job.ast — exoscale/ablauf 0.2.0

Specifies an AST and provides helper functions to build it

action!! clj

(action!! type payload)

(action!! type payload {:keys [idempotent?] :as _opts})

branch? clj

(branch? node)

Predicate to test whether a node is a branch

do!! clj

(do!! & nodes)

Yields a branch of sequential actions

dopar!! clj

(dopar!! & nodes)

Yields a branch of parallel actions

fail!! clj

(fail!!)

Forcibly fail action

finally-nodes clj

(finally-nodes node)

Accessor for finally nodes of a try statement

hierarchy clj

AST node types hierarchy

idempotent-action!! clj

(idempotent-action!! type payload)

leaf? clj

(leaf? node)

Predicate to test whether a node is a leaf

log!! clj

(log!! txt)

Log action

rescue-nodes clj

(rescue-nodes node)

Accessor for rescue nodes of a try statement

try!! clj macro

(try!! & forms)

Yields a try statement, with potential rescue and finally special branches

try-extract clj

(try-extract sym forms)

Tests whether the last form of a list is a list of starting with a special symbol. If found yields a tuple of preceding forms and the last special form list:

 (try-extract 'finally
   '(:foo :bar (finally :bim :bam)))

 ;; => ['(:foo :bar) '(:bim :bam)]

This is used to break apart rescue and finally from try statements

try-nodes clj

(try-nodes node)

Accessor for standard nodes of a try statement

with-augment clj

(with-augment [source dest] node)

Provide a source and dest for ast augment: after node execution, take the value from source and put it in the context's key dest. Both source and dest can be a keyword or a sequence of keywords. see ablauf.job/augment for more details.
