Article contents:== quasiwalk [[toc:]] Quasiwalk is a tree-map that respects quote, quasiquote, and unquote. It's for metaprogramming. (quasiwalk proc tree) Applies {{proc}} to all the non-quoted atoms in {{tree}}. I mean, the tree itself contains symbolic data, obviously (as in, one level of quotedness). (quasiwalk (as-list reverse) '(this is '(an example))) ⇒ (siht si '(an example)) (quasiwalk (as-list reverse) '(this is `(another ,(example)))) ⇒ (siht si `(another ,(elpmaxe))) It can figure out nested levels of quasiquoting and unquoting. The limitation in this version is that if {{quote}}, {{quasiquote}}, or {{unquote}} has been renamed in the environment, it doesn't know that. It works off the original names (e.g. equality to those symbols exactly). (quasiwalk softness proc tree) Quasiwalk, but assume we're already in {{softness}} levels of quasiquotation. Normally you won't need this, but {{quasiwalk}} uses it internally. (quasiwalk* proc tree) This variant runs {{quasiwalk}} for the side-effects but then doesn't return anything. It still does all the same consing as {{quasiwalk}} does, it's literally just {{(define (quasiwalk* proc tree) (quasiwalk proc tree) (void))}} which is sometimes useful. === Source code git clone https://idiomdrottning.org/quasiwalk Description of your changes:
