Functions to transform parse trees

map-preserving-meta clj/s

(map-preserving-meta f l)

merge-meta clj/s

(merge-meta obj metamap)

This variation of the merge-meta in gll does nothing if obj is not something that can have a metamap attached.

transform clj/s

(transform transform-map parse-tree)

Takes a transform map and a parse tree (or seq of parse-trees). A transform map is a mapping from tags to functions that take a node's contents and return a replacement for the node, i.e., {:node-tag (fn [child1 child2 ...] node-replacement), :another-node-tag (fn [child1 child2 ...] node-replacement)}
