meander.match.ir.epsilon — meander/epsilon 0.0.168

Functions for working with the Meander's match compiler intermediate representation (IR).

branch? clj/s

(branch? node)

true if node has any children, false otherwise.

breadth-first? clj/s

(breadth-first?)

true if the current IR compilation environment *env* specifies a :search-order of :breadth-first.

check? clj/s

(check? x)

children clj/s

(children node)

Return the child nodes of node, a sequence of ::node.

compile clj/s

(compile ir fail kind)

(compile ir fail kind env)

compile* clj/s multimethod

(compile* ir fail kind)

def-remove-unused clj/s

(def-remove-unused node)

defop clj/s macro

(defop symbol op params & body)

do-merge clj/s

(do-merge a b then)

(do-merge a b then else)

Attempts to merge two nodes a and b into a new node. If the merge is successful the function then is invoked with the new node. If the merge fails and the optional function else was passed, then else is invoked with a and b. If the merge fails and else was not passed, then the value ::merge-fail is returned.

drop-form clj/s

(drop-form n target-form kind)

fail-form clj/s

(fail-form kind)

Returns (list FAIL) if kind is :search,FAIL otherwise. This is used when compiling :def nodes to ensure the correct type of data is returned to code compiled for :call nodes.

height clj/s

(height node)

Return the height of node.

js-array-equals-form clj/s

(js-array-equals-form a b)

Form used to test if two arrays a and b are equal in ClojureScript.

make-node clj/s

(make-node node new-children)

merge clj/s multimethod

(merge a b)

Attempt to merge the nodes a and b. Returns the result of the merge if the merge succeeds. Returns a :branch node with :arms [a b] if the merge fails.

merge* clj/s multimethod

(merge* node-a node-b)

Attempts to merge two nodes into one node returning node* if successful and ::merge-fail otherwise.

merge-all clj/s

(merge-all nodes)

Attempts to successively merge all nodes in nodes from left to right.

node? clj/s

(node? x)

true if x is a ::node, false otherwise.

nodes clj/s

(nodes node)

Return all subnodes of node, a sequence of ::node.

op clj/s

(op node)

Return the ::op of node.
